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.

The genus Scipopus (Diptera, Micropezidae, Taeniapterinae) is redefined and revised to include the genera previously treated as the “Scipopus group” which included Scipopus Enderlein, Pseudeurybata Hennig, and Phaeopterina Frey. Pseudeurybata is treated as a junior synonym of Phaeopterina and the genus Scipopus is redefined to include three subgenera: Scipopus s. str., Phaeopterina and Parascipopus subgen. nov.. Redescriptions of 18 previously described species, and descriptions of 25 new species are provided as follows: S. (Parascipopus) subgen. nov., S. (Parascipopus) alturas sp. nov., S. (Parascipopus) fenestratus sp. nov., S. (Parascipopus) kubus sp. nov., S. (Parascipopus) monteverde sp. nov., S. (Parascipopus) nigriscapus sp. nov., S. (Parascipopus) otisi sp. nov., S. (Parascipopus) savegre sp. nov., S. (Parascipopus) tico sp. nov., S. (Phaeopterina) argentum sp. nov., S. (Phaeopterina) brunneus sp. nov., S. (Phaeopterina) lineatus sp. nov., S. (Phaeopterina) musculosus sp. nov., S. (Phaeopterina) narupa sp. nov., S. (Phaeopterina) noturgidus sp. nov., S. (Phaeopterina) turgidus sp. nov., S. (Phaeopterina) vee sp. nov., S. (Phaeopterina) fraudator sp. nov., S. (Phaeopterina) metallicus sp. nov., S. (Phaeopterina) quetzal sp. nov., S. (Phaeopterina) uniformis sp. nov., S. (Scipopus) brikelos sp. nov., S. (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.

The Palaearctic longhorn beetle Stictoleptura cordigera (Füssli, 1775) (Cerambycidae: Lepturinae: Lepturini) is recorded for the first time in Chile, based on specimens collected in a rural locality of the Maule Region. This new record is the first in the New World and increases to eleven the number of exotic cerambycids introduced and established in the Chilean territory. A brief diagnosis for recognition of the species and data about its distribution and natural history are provided. The possible route of entry of this cerambycid into Chile is discussed.

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.
