The cosmopolitan pipunculid genus Dasydorylas Skevington, 2001 includes just a few species from the Neotropical Region and is completely unknown to Colombia. Three new species of Dasydorylas are described from protected areas and conflict territories of limited access in Colombia, namely Dasydorylas colombiensis sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Boyacá), D. gibber sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Boyacá), and D. santainesensis sp. nov. (type locality: Páramo de Santa Inés, Belmira, Antioquia). Diagnoses, illustrations and distributional data of the new species are presented. Dasydorylas nigellus (Rafael, 1991) is recorded for the first time from Colombia and its amended diagnosis is provided. An identification key to males of all Neotropical species is presented. With this paper, the number of Neotropical species of Dasydorylas is increased from six to nine.
An overview of the genus Psephenops Grouvelle (Coleoptera: Psephenidae: Psepheninae) is provided with geographic distributions of the species. The taxonomic history of Psephenops smithi Grouvelle, the type species from Grenada and St. Vincent, and junior synonym Xexanchorinus latus Grouvelle from Grenada, is discussed, and lectotypes and paralectotypes are designated for both. Photographs of the type series and a non-type specimen with illustrated male genitalia, along with new distributional information for the species, are provided. The male, female, and associated larva of Psephenops trini Barr and Shepard, new species, are described and illustrated, as is the habitat of this species in Trinidad and Tobago. The Peruvian species Psephenus robacki Spangler is transferred from Psephenus Haldeman to Psephenops as Psephenops robacki (Spangler) new combination. Photographs of the female holotype are included, and possible new distributional records from Peru are reported.

A contribution to the taxonomy of the genus Pelecium Kirby (Coleoptera: Carabidae: Peleciini)
(2024)
Pelecium Kirby, 1817 is a neotropical genus of flightless carabid beetles comprising 34 species, distributed from Panama to middle Argentina. Most species of Pelecium are known from short series and few localities, in some cases only from the holotype. Male and female abdominal terminalia are not described for the majority of the species, a situation that makes it difficult to describe new species or to study intraspecific variation. Here, we describe nine new species based on individuals from Brazil: Pelecium buckupi sp. nov., P. fistulosus sp. nov. and P. zaguryi sp. nov. from the Centre-West region, P. belloi sp. nov., P. chrissquirei sp. nov., P. straneoi sp. nov. and P. zophos sp. nov. from the Southeast region, and P. balli sp. nov. and P. grossii sp. nov. from the South region. We also provide new distributional records and descriptions of abdominal terminalia for twelve species: Pelecium atroviolaceum Straneo & Ball, 1989, P. bolivianum Straneo & Ball, 1989, P. cyanipes Kirby, 1817, P. helenae Straneo & Ball, 1989, P. laeve Chaudoir, 1854, P. negrei Straneo, 1962, P. drakei Quedenfeldt, 1890, P. punctatostriatum Straneo, 1970, P. purpureum Straneo, 1955, P. rotundipenne Schaum, 1860, P. striatum Straneo, 1955 and P. violaceum Brullé, 1838.
Two new species and one new genus of Lamiinae (Coleoptera: Cerambycidae) are described in Acanthocinini: Embera flava new species, new genus, from Panama; and Nealcidion lingafelteri new species from Costa Rica. The species-group name of Nealcidion napoensis Nascimento and McClarin, 2018 is corrected and morphological variations in Leptostylus cristulatus Bates, 1872 are reported. Trypanidius mimicavus Carelli, Monné, and Souza, 2013 is redescribed and transferred to Carphina Bates, 1872, forming the new combination Carphina mimicavus. Colombicallia curta Galileo and Martins, 1992 (Calliini) is recorded from Panama for the first time.

The Neotropical eucnemid genus, Dyscolotaxia Horn, is revised following the examination of specimens from five collections, examination of the published original description of Plesiofornax tetratoma Chassain, and from images provided by Fernanda Salazar-Buenaño (QCAZI). Dyscolotaxia championi Horn is redescribed with included descriptions of the male genitalia and a female specimen. Three new species of false click beetles (Coleoptera: Eucnemidae) are described from the Neotropical region. These new species are: Dyscolotaxia chiriquiensis (Panama), Dyscolotaxia hispaniolensis (Dominican Republic) and Dyscolotaxia picea (Ecuador). Amazotaxia new genus is described from South America for Plesiofornax tetratoma Chassain, creating Amazotaxia tetratoma (Chassain) new combination. Morphology of both Dyscolotaxia and Amazotaxia in relation to Pleisofornax Cocquerel are reviewed along with biogeographical hypotheses for these groups. An identification key is provided for species of Dyscolotaxia in the Neotropical region. Images for all species of Dyscolotaxia and Amazotaxia are provided.
Aksakidion odontokeras, new genus and new species (Coleoptera: Chrysomelidae: Eumolpinae: Eumolpini), is described from four specimens in the Bowditch Collection at Harvard University. It is distinguished from all other genera in the Eumolpinae by an elongate, seta-bearing, tusk-like projection on the dorsal side of each mandible. Although locality data only mention Paraguay as the country of origin, information about the collector indicates it was collected in the late 19th century in the vicinity of Asunción.

(Scipopus) convexus sp. nov., S. (Scipopus) nitidus sp. nov., S. (Scipopus) planus sp. nov., and S. (Scipopus) wokomung sp. nov. Scipopus (Scipopus) limbativertex Enderlein is a new junior synonym of S. (Scipopus) nigripennis (Hendel), S. (Scipopus) bolivianus Hennig is a new junior synonym of S. (Scipopus) belzebul (Schiner), S. (Scipopus) frit Cresson is a new junior synonym of S. (Scipopus) calocephalus (Bigot) and S. (Scipopus) alvarengai Albuquerque is a new junior synonym of S. (Scipopus) erythrocephalus (Fabricius). The phylogeny of Scipopus s. lat. and its presumed outgroup (a clade containing Rainieriella Aczel) is considered using morphological and molecular data and supported with a maximum likelihood tree for the genes 12S, 28S and COI.

New taxa in Hesperiidae (Lepidoptera: Papilionoidea) are traditionally proposed after inspection of male genitalia, which largely form the basis for Hesperiidae taxonomy. However, with genomic DNA sequencing, even a single female specimen can be placed in a phylogenetic context of existing classification and taxonomically assigned with confidence. Genomic sequencing of an unusually patterned Hesperiidae female from San Martin, Peru, characterized by pearly spots outlining an inverted heart pattern on the rust-colored ventral hindwing, reveals that it represents an undescribed genus and species named here as Gemmia buechei Brockmann and Grishin, new genus and new species.

In this study, the new genus Spanglerelmis Polizei & Bispo is described; Microcylloepus ochus Hinton, 1940 is synonymized with Microcylloepus femoralis Hinton, 1940, and transferred to the new genus; and two new species, S. xiririca gen. et sp. nov. and S. timburi gen. et sp. nov. are described. The new genus can be characterized by the combination of the following characters: 1) pronotum without transverse, longitudinal or oblique impressions, sulci or gibbosities on disc; 2) elytra with a carina on interval III and two sublateral carinae on intervals V and VI; 3) mesoventrite with sides strongly raised; and 4) femora with an oblique belt of tomentum dorsally and a transverse belt ventrally. The specimens of the two new species were collected mainly in riffles of unimpacted streams in the Atlantic Forest in São Paulo State, Brazil. Scanning electron microscope images, an identification key for the genus and habitat notes are also presented.
Revision of the high Andean genus Eremophygus Ohaus (Coleoptera: Scarabaeidae: Rutelinae: Rutelini)
(2022)
The genus Eremophygus Ohaus, 1910 (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), endemic to the Andean biogeographic region, is revised and now includes two altiplanic species: Eremophygus lasiocalinus Ohaus, 1915 and Eremophygus philippii Ohaus, 1910. A redescription of the genus and included species, diagnoses, distribution records, and a key to species are provided. Additionally, photographs of the type specimens are included. Based on examination of type specimens of all species-group names, Eremophygus bicolor (Gutiérrez, 1951) and Eremophygus pachyloides Ohaus, 1925 are new synonyms of Eremophygus lasiocalinus, while Eremophygus leo Gutiérrez, 1951 is a new synonym of Eremophygus philippii. Lectotypes are designated for E. lasiocalinus, E. pachyloides, and E. philippii. Eremophygus philippii is formally reported from Argentina.

Large ants are not easy – the taxonomy of Dinoponera Roger (Hymenoptera: Formicidae: Ponerinae)
(2021)
The taxonomy of the giant ants of the genus Dinoponera is revised based on female and male morphology. Eight species are recognized. Dinoponera nicinha sp. nov., from Amazonas and Rondônia, Brazil, is described and D. grandis (Guérin-Méneville, 1838) is revived. The species D. australis Emery, 1901 and D. snellingi Lenhart, Dash & Mackay, 2013, plus the subspecies D. australis bucki Borgmeier, 1937 and D. australis nigricolor Borgmeier, 1937 are synonymized under D. grandis sp. rev. An unnamed and unidentified male is reported. In general, male morphology has greater and more discrete variation than in females, but they are scarce in museum collections. Species distributions are updated and illustrated, the genus ranging from southern Colombia to northern Argentina, with no reliable records from the Guiana Shield and all nominal species occurring in Brazil. Intraspecific variation and natural history are discussed. New illustrated identification keys are provided for both sexes. Future studies should address the collection of fresh specimens for molecular work and to assess the conservation status of several species and populations.
Seven new species of Cacostola Fairmaire and Germain, 1859 (Coleoptera: Cerambycidae: Lamiinae: Onciderini) are described: C. plotkini Wappes and Santos-Silva from Costa Rica; C. galenae Wappes and Santos- Silva from Panama; C. opitzi Wappes and Santos-Silva from Bolivia; C. howdenae Wappes and Santos-Silva from Guatemala; C. thomasorum Wappes and Santos-Silva from Brazil; C. nearnsi Wappes and Santos-Silva from Bolivia and Panama; and C. rothschildi Wappes and Santos-Silva from Argentina and Brazil. Notes on C. simplex (Pascoe, 1859), and C. mexicana (Breuning, 1943) are also included.
Five new species and one new genus in Neotropical Lamiinae (Coleoptera: Cerambycidae) are de-scribed: Cotycicuiara lingafelteri Wappes and Santos-Silva, from Panama (Acanthoderini); Nesozineus morrisi Wappes and Santos-Silva, from Bolivia (Acanthoderini); Trichoanoreina panamensis Wappes and Santos-Silva, from Panama (Acanthoderini); Callisema skillmani Wappes and Santos-Silva, from Bolivia (Calliini); Rileyellus panamensis Wappes and Santos-Silva, new genus and species, from Panama (Desmiphorini). Callia pulchra Melzer, 1930 is placed in synonymy with Callia axillaris (Dalman, 1823).
The number of specimens in the type series of Hemilophus leuconotus Laporte, 1840 (= Cirrhicera leuconota) is corrected. Cirrhicera leucronota Thomson, 1857 (Coleoptera: Cerambycidae: Lamiinae: Hemilophini), currently considered lapsus calami or an error to C. leuconotus, and the number of specimens in the type series is also corrected. Cirrhicera leuconota is recorded from Guatemala for the first time. The sex of the holotype of Lamacoscylus albatus Martins, Santos-Silva and Galileo, 2015, is corrected, and a new state record in Mexico is provided. The description of the antennae in females of Lamacoscylus Martins and Galileo,1991 is discussed; Malacoscylus humilis Bates,1881 (currently Lamacoscylus humilis) sensu Gahan (1892) is discussed and the two varieties described by him, M. humilis var. fulvescens and M. humilis var. grisescens (only part of the speci-mens), as well as M. usingeri Linsley,1935 are transferred to Schmidarius Santos-Silva, Heffern, Botero and Nascimento, new genus. Additionally, a new species from Mexico (Mexico) is described in Schmidarius as S. kondratieffi Santos-Silva, Heffern, Botero and Nascimento. The correct type-species of Phoebe Audinet-Serville,1835 is determined as Saperda bicornis Olivier,1800 and Phoebe phoebe Lepeletier and Audinet-Serville,1825 and Phoebe tinga Martins and Galileo,1998 are transferred to Phoebella Lane,1966, which is redescribed. Leucophoebe Lane,1976 is synonymized with Phoebe. A key to species of Hemilophini with 12-segmented antennae is provided. The differences between Callanga Lane,1973 and Lapazina Lane,1973 are discussed, and a new species of Callanga from Peru is described as C. ashaninka Santos-Silva, Heffern, Botero and Nascimento. A new species of Fredlanea Martins and Galileo,1996 from Colombia is described as F. lazulina Santos-Silva, Heffern, Botero and Nascimento; a new department record in Colombia is provided for Fredlanea consobrina (Lane,1970) and a chromatic variation in this species is discussed.
Nomenclatural and taxonomic changes are proposed for American Apomecynini (Coleoptera: Cerambycidae: Lamiinae). New synonymies: Parmenonta valida Thomson, 1868, type species of Parmenonta Thomson, 1868, is transferred to Adetus LeConte, 1852, making obligatory the synonymy of Parmenonta with Adetus; Adetus cylindricus Bates, 1866 = A. inaequalis (Thomson, 1868); Adetus leucostigma Bates, 1880 = Adetus binotatus (Thomson, 1868); Adetus tuberosus Galileo and Martins, 2003 = Typophaula melancholica Thomson, 1868; Adetus latericius Belon, 1902, and Adetus irregularis (Breuning, 1939) = Adetus nanus (Fairmaire and Germain, 1859).

The genus is comprised of four new species, all described by Skelley and Gasca-Álvarez: D. belamyi, D. dathomirria, D. pulcricolor, and D. tomasi. The unique broad head structures of this genus are characterized and compared with other genera. Problems associated with the taxonomy of Erotylini are discussed.
Five small species groups of Traumatomutilla André, 1901 are revised. A new species, T. pilkingtoni Bartholomay and Williams sp. nov. (Argentina) is described and placed within its own species group. All known species of the bellica, diabolica, vitelligera, and bifurca species groups are redescribed. New synonymies are proposed for T. vitelligera (Gerstaecker, 1874) = Mutilla fascinata Smith, 1879, syn. nov.; = Traumatomutilla comata André, 1906, syn. nov. and for T. bifurca (Klug, 1821) = T. ira Casal, 1969, syn. nov. The lectotypes of Mutilla bifurca Klug, 1821 and Mutilla comata André, 1906 are designated. The hitherto unknown males of T. vitelligera and T. bifurca are diagnosed and described.
Four new species in the genus Amphicnaeia (Coleoptera: Cerambycidae: Lamiinae) are described: A. panamensis Wappes, Santos-Silva and Galileo and A. fuscofasciata Wappes, Santos-Silva and Galileo from Panama; A. bezarki Wappes, Santos-Silva and Galileo from Venezuela; and A. rileyi Wappes, Santos-Silva and Galileo from Costa Rica and Panama. Amphicnaeia affinis Breuning, 1940 is placed in synonymy with A. lineata Bates, 1866, and the species newly recorded from the Brazilian state of Minas Gerais. Amphicnaeia cordigera Aurivillius, 1920 is transferred to Rosalba Thomson, 1864, resulting in a new combination, and Rosalba rufescens Breuning, 1940, is found to be a junior synonym of the former. The holotypes of A. vitticollis Breuning, 1940, and A. villosula (Thomson, 1868) are illustrated for the first time.
A new species of ant-mimicking spider of the subfamily Castianeirinae, Myrmecotypus rubrofemoratus Perger and Rubio, new species (Araneae: Corinnidae), is described from the Pre-Andean area of the Bolivian orocline. Adults of M. rubrofemoratus new species resemble the carpenter ant Camponotus femoratus Forel, 1907, which is considered one of the most aggressive ants in the world.
The genus Microogenius Gutiérrez (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), endemic to the Andean biogeographic region, is revised and now includes six species: Microogenius arrowi (Ohaus) (Bolivia), Microogenius borealis sp. nov. (Peru), Microogenius gutierrezi Martínez (Bolivia), Microogenius lanterii (Soula) (Argentina), Microogenius martinezi Gutiérrez (Bolivia) and Microogenius puna sp. nov. (Bolivia, Chile, Peru). Redescription of the genus, individual diagnoses, identification keys and distribution records for all known species are provided. Additionally, photographs of adults and of diagnostic morphological characters are included. Eremophygus calvus Gutiérrez, based on the female holotype, is synonymized under Microogenius arrowi (Ohaus), based on the male lectotype. The genus Microogenius is recorded for the first time for the altiplano of Chile and Peru based on specimens of a new species that has been long confused with Eremophygus lasiocalinus Ohaus.
Descriptions of a new genus, Giesberticus Wappes and Santos-Silva, and seven new species in the Rhinotragini (Coleoptera: Cerambycidae: Cerambycinae) are included: Oxylymma soniae Wappes and Santos-Silva, from Bolivia; O. surinamensis Wappes and Santos-Silva, from Suriname; O. birai Wappes and Santos-Silva, from Brazil; Paraeclipta albopilosa Wappes and Santos-Silva, from Bolivia; P. vandenberghei Wappes and Santos- Silva, from Nicaragua; Odontocera elllanocarti Wappes and Santos-Silva, from Panama; and Giesberticus longiventris Wappes and Santos-Silva, from Bolivia. In addition, the holotype of Oxylymma gibbicollis Bates, 1873 is figured for the first time, Odontocera argenteolineata Santos-Silva and Bezark, 2016 is newly recorded for Guatemala and the Bolivian record for Odontocera globicollis Zajciw (based on a misidentification), is excluded from the Bolivia fauna.
Hamaticherus Dejean, 1821 (Coleoptera: Cerambycidae: Cerambycinae) is considered a junior synonym of Cerambyx Linnaeus, 1758. Hamaticherus sensu Audinet-Serville, 1834 is considered a posterior usage of Hamaticherus Dejean, 1821, and an unavailable name. Plocaederus is considered as a new genus, and not a replacement name, proposed by Dejean (1835) to allocate the species included in Hamaticherus sensu Audinet-Serville, 1834. Therefore, a new genus, Hamaederus Santos-Silva, Garcia and Botero,is herein proposed to include the species currently allocated in Plocaederus Dejean, 1835, creating 15 new combinations, and additionally, a new species from French Guiana, Hamaederus allofasciatus Santos-Silva, Garcia and Botero, is described. Furthermore, Plocaederus barauna Martins and Monné, 2002 and Plocaederus confusus Martins and Monné,2002 are proposed as new junior synonyms of Hamaederus yucatecus (Chemsak and Noguera, 1997), and Hamaticherus bellator Audinet-Serville, 1834 is transferred to Plocaederus Dejean,
1835, new combination. New geographical records are provided for Hamaederus fraterculus (Martins), H. glaberrimus (Martins), H. rusticus (Gounelle), and H. yucatecus (Chemsak and Noguera). Hamaederus fasciatus is formally excluded from the fauna of French Guiana. A key to American genera of Cerambycina (Cerambycini) is provided.
Species-specific ant resemblance in heteronotine membracids (Hemiptera: Membracidae) is reported for the first time, providing evidence for ant mimicry. The shape, integument color and shine of the pronotal process of females of Heteronotus fabulosus Boulard closely resemble workers of the cooccurring giant turtle ant Cephalotes atratus (Linnaeus) (Hymenoptera: Formicidae). The entire membracid appears to mimic a mutualistic relationship between a membracid and a turtle ant.
Two new species of Cerambycidae (Coleoptera) are described from Bolivia: Compsibidion woodleyi Wappes, Santos-Silva and Galileo (Cerambycinae: Neoibidionina): and Drycothaea dozieri Wappes, Santos-Silva and Galileo (Lamiinae: Calliini). Illustrations of the new species are included. Mallodon downesii Hope, 1843 (Prioninae: Macrotomini) is reported for the first time in Costa Rica.
This is the first part of a revision of the type specimens of the South American Sericini. Herein, we examine type specimens of Astaena described by Lawrence Webster Saylor (1913–1999). We provide diagnostic redescriptions, images of habitus, aedeagus, and labels of the type specimens of all 18 species described by him in the genus Astaena. We raise Sayloria Frey, 1973, a former subgenus of Symmela Erichson, 1835 that includes three species, to genus level. Our study results in the following new combinations and synonymy: Sayloria bicoloripes (Saylor, 1946) comb. nov. (= A. postnodata Frey, 1973 syn. nov.), S. abcora (Saylor, 1946) comb. nov. (= A. apolinarmaria Saylor, 1946 syn. nov.) and S. pottsi (Saylor, 1946) comb. nov.
Three species of Synemosyna Hentz, 1846 were recorded during a survey in five Bolivian forest ecoregions: S. aurantiaca (Mello-Leitão, 1917), S. myrmeciaeformis (Taczanowski, 1871) and S. nicaraguaensis Cutler, 1993. Synemosyna aurantiaca and S. nicaraguaensis are recorded for Bolivia for the first time and the previously unknown male of S. nicaraguaensis is described and illustrated. The habitus and the genitalia of the female of S. myrmeciaeformis are illustrated for the first time. Synemosyna aurantiaca occurs in semi-deciduous forests south of 18° S and S. myrmeciaeformis in the Bolivian Yungas forest and ecoregions of the Amazon biome north of 16° S. Synemosyna nicaraguaensis is possibly an Andean species that enters into the moist Isthmian forests of Central America. Several potential mimicry complexes with two broad patterns were observed: sex-specific polychromatic mimicry (S. nicaraguaensis), and transformational mimicry involving smaller orange and larger brown to dark-brown forms (S. aurantiaca and S. myrmeciaeformis).
The genus Onychelmis Hinton, 1941 was for a long time regarded as a small taxon with only three known species distributed in the Andes. A study of new material from Ecuador, using morphological and molecular data, has resulted in the discovery of five new species: Onychelmis lenkae sp. nov., O. lobata sp. nov., O. minor sp. nov., O. onorei sp. nov. and O. splendida sp. nov. We also revised the entire genus and redescribed the three known species, O. longicollis (Sharp, 1882), O. leleupi Delève, 1968 and O. whiteheadi Spangler & Santiago, 1991. Habitus photographs of adults are provided, together with line drawings of male and female genitalia, and schematic illustrations of the distribution of femoral tomentum for each species. DNA sequences for barcoding the COI mtDNA fragment were used to support species delimitation and to suggest possible relationships among species. The revision includes a key to adults of all species of Onychelmis and notes on the biogeography of the genus, with an updated distribution map.
The adult stage of Helioandesia tarregai gen. et sp. nov. (Lepidoptera: Yponomeutoidea: Heliodinidae) is described and illustrated from the arid western slopes of the Andes of northern Chile. The larvae of H. tarregai gen. et sp. nov. feed as leaf skeletonizers on Mirabilis acuta (Reiche) Heimerl (Nyctaginaceae). The mostly gray forewing of H. tarregai gen. et sp. nov., ornamented with strongly bulging metallic spots, resembles that of the representatives of the mainly Nearctic Lithariapteryx Chambers, 1876. However, the latter lacks CuP in the forewing, has a single bristle in the female frenulum, and lacks a well-developed cornutus. Helioandesia gen. nov. clustered as sister to Neoheliodines Hsu, 2004 in a cladistic analysis, although no synapomorphies were found for this cluster, while Lithariapteryx was sister to Helioandesia gen. nov. + Neoheliodines based on two synapomorphies. The genetic distance between a DNA barcode sequence of H. tarregai gen. et sp. nov. and representatives of other genera of Heliodinidae Heinemann, 1877 was 9.0–12.5% (K2P), and a maximum likelihood analysis based on this molecular marker confirmed the placement of H. tarregai gen. et sp. nov. as a member of this micromoth family. This contribution represents the first confirmed record of Heliodinidae for Chile.
In 1842, J.D. Hooker collected a number of mosses on Hermite Island (Cape Horn region). From one of those gatherings, Hooker 141, four species of Ulota have been described: U. luteola, U. fuegiana, U. glabella, and U. eremitensis. The first two species are widely accepted, whereas the identity of the latter two has been recently discussed, and the names are now synonymized under U. fuegiana, the more widely distributed species in the Tierra del Fuego archipelago. Our studies, based on recent collections of Orthotrichaceae from Patagonia, show that specimens different from those of U. fuegiana and agreeing with the protologues of both U. glabella and U. eremitensis are common in Patagonia. Comparisons with type material of all four names demonstrate that the type for U. glabella is in such bad condition that it cannot be used, and an epitype should be selected. In this paper, we comment on the whereabouts of the collection Hooker 141 and the species described from it, discuss the distinct identity of U. glabella and its relationship with U. eremitensis as well as its differentiation from other species, present a diagnostic description of U. glabella and, finally, select an epitype to fix the application of this name.
The spider genus Bistriopelma Kaderka, 2015 is endemic to Peru and includes three species known to date: Bistriopelma lamasi Kaderka, 2015, B. matuskai Kaderka, 2015 and B. titicaca Kaderka, 2017. The present contribution diagnoses, describes and illustrates two new species of Bistriopelma from Peru: B. peyoi sp. nov. and B. kiwicha sp. nov., both based on male and female. The male of B. peyoi sp. nov. is provided with a remarkable thoracic horn, and the species is the first horned tarantula for this genus. An updated distribution map for all known species is presented.
The Neotropical genus Mesoconius Enderlein, 1922 is revised with the redescription or diagnosis of 20 previously described South American species, the description of one new species of the M. infestus group (M. triunfo sp. nov.) from Mexico and the description of 32 new species in four species groups from Andean South America (M. eques group: M. albiseta sp. nov., M. albitergum sp. nov., M. anchitarsus sp. nov., M. cosanga sp. nov., M. epandribarba sp. nov., M. hirsutimamma sp. nov., M. nigripleuron sp. nov., M. noteques sp. nov., M. pasachoa sp. nov., M. rufipleuron sp. nov. and M. suzukii sp. nov.; M. infestus group: M. acca sp. nov., M. albipedis sp. nov., M. nigricephala sp. nov. and M. notacca sp. nov.; M. nono group: M. aurantium sp. nov., M. bipleuron sp. nov., M. garyi sp. nov., M. nono sp. nov., M. reinai sp. nov., M. uchumachi sp. nov., M. woytkowskii sp. nov. and M. zorro sp. nov.; M. oblitus group: M. apa sp. nov., M. apicalis sp. nov., M. gelbifacies sp. nov., M. keili sp. nov., M. lobopoda sp. nov., M. nigra sp. nov., M. quadritheca sp. nov., M. rex sp. nov. and M. ruficrus sp. nov.). Calobata eques Schiner, 1868 is transferred from Cliobata Enderlein, 1923 to Mesoconius and all South American species previously treated as Zelatractodes Enderlein, 1922 are transferred to Mesoconius. Mesoconius aeripennis Enderlein, 1922 is synonymized with M. eques, M. enderleini Frey, 1927 is synonymized with M. infestus Enderlein, 1922 and Aristobata melini Frey, 1927 is synonymized with M. filipes (Enderlein, 1922). Mesoconius garleppi (Enderlein, 1922) is newly recognized as a subjective junior homonym and given the replacement name Mesoconius ottoi nom. nov. A maximum likelihood tree is provided for 29 species of Mesoconius sequenced for the barcode region of CO1 and a key is provided for all South American species of Mesoconius.
The gigas species group of the subgenus Canthidium (Neocanthidium) is defi ned and described. This species group is composed of three described species [C. gigas Balthasar, 1939, Brazilian Atlantic Forest, including intrusions into Cerrado, C. bokermanni (Martínez et al., 1964), Chaco and western Cerrado in Brazil, Bolivia, Paraguay, and Argentina, and C. kelleri (Martínez et al., 1964), Brazilian Cerrado and neighbouring open areas] and three new species: Canthidium stofeli sp. nov. from the western and southern regions of the Brazilian Amazon, Canthidium feeri sp. nov. from French Guiana, and Canthidium ayri sp. nov. from the Brazilian Atlantic Forest. We present descriptions and redescriptions, illustrations, an identifi cation key and comments on the distributions of the species of the gigas group.
Four new species of Lobolibethra Hennemann & Conle, 2007 (Diapheromerinae: Diapheromerini: “Clonistria-group”) are described and illustrated. Lobolibethra carbonelli sp. nov. and L. pozuzoae sp. nov. from eastern Peru are described from both sexes and the eggs, L. tricarinata sp. nov. from southeast Ecuador is described from the female and male, and L. verruculosa sp. nov. from eastern Peru is described from the male. The previously unknown males of the Peruvian L. mainerii (Giglio-Tos, 1910) and L. mutica Hennemann & Conle, 2007 are described and illustrated. Dyme iconnicoffi Caudell, 1918 is shown to represent the previously unknown male of L. mainerii (Giglio-Tos, 1910) and is synonymised (syn. nov.). An updated key is presented for the eleven known species of Lobolibethra.
Four new species of Nyctonympha Thomson, 1868 are described: N. antonkozlovi sp. nov. and N. sinjaevi sp. nov. from Colombia, N. birai sp. nov. from Venezuela and N. mariahelenae sp. nov. from Brazil (Rondônia), Bolivia and Peru. Nyctonympha flavipes Aurivillius, 1990 is formally excluded from the Peruvian and Brazilian fauna. A provisional key to species of Nyctonympha is provided.
A new species of the Andean stag beetle genus Auxicerus Waterhouse, 1883 is described from the humid Tucuman-Bolivian forest in the southern Bolivian Andes. Auxicerus magnipunctatus sp. nov. is distinguished from all congeners by the distinctly larger punctures of the mesosternum; antennomeres 2–6 subquadrate, last two joints of club wider than long; lamellae not widely separated; posterior end of ocular canthus rounded and anterior edge of canthus moderately developed into an obtuse triangle. Auxicerus magnipunctatus sp. nov. is possibly endemic to the Tucuman-Bolivian forest. Along with the presence of other endemic beetle species with tropical congeners, the discovery of A. magnipunctatus sp. nov. supports the idea that the persistence of rather tropical taxa in the subtropical realm is fostered by increased humidity at orographic rain barriers and climatic stability in the Tucuman-Bolivian forest.
Macunahyphes zagaia sp. nov. and M. araca sp. nov. are described based on imagines collected from the Amazon biome in Brazil. Specimens belonging to all species of the genus were examined and a diagnosis for each one is provided. Variation seen in the male imago of M. eduardoi is described, as well as the female and egg for the first time. Together with M. eduardoi, the two new species share the presence of a basal swelling on segment II of the forceps, which raises important questions concerning the evolution of this character in Leptohyphidae. Finally, a re-definition of the genus is proposed.
An early, overlooked description of the genus Atelodesmis (Coleoptera, Cerambycidae, Lamiinae) is attributed to Chevrolat (in Duponchel and Chevrolat 1841), with A. mannerheimii Duponchel and Chevrolat, 1841 as its type species, and the genus redescribed. Atelodesmis Buquet, 1857, is a junior synonym and primary homonym of Atelodesmis Chevrolat. Atelodesmis hirticornis Buquet, 1857 and A. vestita Buquet, 1857 are synonymized with A. mannerheimii. Fallaxdesmis is described as a new genus with Atelodesmis unicolor Buquet, 1857 as type species. Atelodesmis piperita Bates, 1855 is transferred to Eupogonius and newly recorded for the state of Oaxaca, Mexico. A new species for Mexico and Guatemala, Eupogonius giesberti, is described. The following new combinations are established: Fallaxdesmis unicolor (Buquet, 1857) and Eupogonius piperita (Bates, 1855). Illustrations of A. mannerheimii, Fallaxdesmis unicolor, and the holotypes of A. hirticornis, A. vestita, A. unicolor, A. piperita and Eupogonius giesberti are included.
Adesmus martinsi (Coleoptera, Cerambycidae, Lamiinae, Hemilophini), a new species from Bolivia, is described, illustrated, and included in a previous key. The new species displays gender dimorphism in the pubescent pattern and in anatomical structure. Thus, Adesmus becomes the second genus recorded in the Hemilophini to have visual chromatic dimorphism.
Hemidactylus frenatus is an Asian gecko species that has invaded many tropical regions to become one of the most widespread lizards worldwide. This species has dispersed across the Pacific Ocean to reach Hawaii and subsequently Mexico and other Central American countries. More recently, it has been reported from northwestern South America. Using 12S and cytb mitochondrial DNA sequences I found that South American and Galápagos haplotypes are identical to those from Hawaii and Papua New Guinea, suggesting a common Melanesian origin for both Hawaii and South America. Literature records suggest that H. frenatus arrived in Colombia around the mid-‘90s, dispersed south into Ecuador in less than five years, and arrived in the Galápagos about one decade later.
A new genus and two new species of Argentine Rhinotragini
(Coleoptera, Cerambycidae, Cerambycinae)
(2017)

Two Neoibidionini from Bolivia are described as new: Neocompsa schneppi sp. nov. and Tropidion nancyae sp. nov. The new species are compared to closely related species and previous keys by Martins and Galileo (2007, 2009) are modifi ed to include them. Illustrations of dorsal, ventral and lateral habitus, as well as head structures are included for both species. Comments are also included on color and pattern variation of each species.
Two new species of Corimbion Martins, 1970 are described from Bolivia: Corimbion kuckartzi and Corimbion ledezmae. A previous key to the South American species of Corimbion (Martins 2009) is herein modified to include the new species. Dorsal, ventral and lateral habitus illustrations, as well as variation in color and dorsal pattern for C. kuckartzi, are also presented.
