The Acanthocinini genus Alcathousiella Monné, 2005 (Coleoptera, Cerambycidae, Lamiinae) is revised with both the genus and the type species, Alcathousiella polyrhaphoides (White, 1855) redescribed. New country records for the species, greatly expanding its known distribution in South America, are also presented. Lastly, Alcathousiella giesberti sp. nov., from Nicaragua, Costa Rica and Panama is described and illustrated.
The taxonomy of Micronectidae in Vietnam is reviewed. Based on our cumulative collections during 2001–2020, 11 new species of Micronecta Kirkaldy, 1897 are documented and described in this study: M. acuminata sp. nov., M. arcuata sp. nov., M. caperata sp. nov., M. clavata sp. nov., M. cultellata sp. nov., M. fulvopicta sp. nov., M. nieseri sp. nov., M. pingae sp. nov., M. sinuata sp. nov., M. undulata sp. nov., and M. vietnamica sp. nov. Nine species are recorded from Vietnam for the first time: M. decorata Lundblad, 1933, M. drepani Nieser, 2000, M. erythra Nieser, Chen & Yang, 2005, M. fugitans Breddin, 1905, M. johorensis Fernando, 1964, M. melanochroa Nieser, Chen & Yang, 2005, M. ornitheia Nieser, Chen & Yang, 2005, M. sahlbergi (Jakovlev, 1881), and M. tuwanoni Nieser, Chen, Leksawasdi, Thanyakam & Duangsupa, 2004. Thus, in this study, two genera and 37 species of Micronectidae are now reported from Vietnam: Synaptonecta Lundblad, 1933 with only one species, S. issa (Distant, 1910), and Micronecta with 36 species. A key to all species occurring in Vietnam, subgeneric diagnoses, and a key to all current subgenera of Micronecta are provided.
Two new species of Sonerila Roxb. (Melastomataceae), S. erectifolia Phonep., Soulad. & Tagane sp. nov. from southern Laos, and S. souvannii Phonep. & Soulad. sp. nov. from central Laos, are described and illustrated. Comparisons with morphologically similar species are presented, along with ecological information and preliminary conservation status. A key to the species of Sonerila in Laos is also provided.
New species, revision, and phylogeny of Ronzotherium Aymard, 1854 (Perissodactyla, Rhinocerotidae)
(2021)
Ronzotherium is one of the earliest Rhinocerotidae in Europe, which first appeared just after the Eocene/Oligocene transition (Grande Coupure), and became extinct at the end of the Oligocene. It is a large-sized rhinocerotid, with a special position in the phylogeny of this group, as being one of the earliest-branching true Rhinocerotidae. However, its intra-generic systematics has never been tested through computational phylogenetic methods and it is basically unknown. Its taxonomical history has gone through numerous complications, and thus we aim to provide here a complete revision of this genus, through phylogenetic methods. After a re-examination of all type specimens (five supposed species) as well as of most well-preserved specimens from all over Europe and ranging through the complete Oligocene epoch, we performed a parsimony analysis to test the position of some problematic specimens. According to our results, five species can be distinguished, Ronzotherium velaunum (type species), R. filholi, R. elongatum and R. romani as well as a new species: R. heissigi sp. nov. We also drastically re-interpret its anatomy and show that the ‘short-limbed’ “Diaceratherium” massiliae, described from Southern France, can be considered as a junior synonym of R. romani. Finally, we exclude the Asian species “Ronzotherium” orientale and “Ronzotherium” brevirostre from Ronzotherium and we consider R. kochi as a junior synonym of R. filholi.
A morphological and molecular review of the genus Goniurosaurus, including an identification key
(2021)
The genus Goniurosaurus (tiger geckos) currently consists of 23 species distributed in China, Japan and Vietnam. Several species complexes and recent discoveries of cryptic species pose challenges to the species identification, which is crucial to effectively implement the recent listing of the species from China and Vietnam in CITES Appendix II and the species from Japan in CITES Appendix III. Based on the results of our field work in northern Vietnam and data compiled from literature, we herein provide a taxonomic review of the genus Goniurosaurus. Our phylogenetic analyses showed that all recorded populations of tiger geckos from Vietnam, which were found to be monophyletic with low intra-specific genetic divergences, are assigned to one of the four species: G. catbaensis, G. huuliensis, G. lichtenfelderi or G. luii. Both genetic and morphological analyses confirm that the species from China and Vietnam can be split into three major groups. Based on the newly collected data, we provide an extended morphological description of the Vietnamese species. In addition, we provide an identification key for all Goniurosaurus species from China, Japan and Vietnam in order to assist authorities in the enforcement of the recent CITES listing.
The Smicridea (Smicridea) fasciatella species group occurs from the southwestern USA, throughout Central America, the Greater Antilles islands, and most of South America, except for the Chilean subregion. It is characterized by the phallic apparatus being a simple tube with eversible internal sclerites at the apex. The fasciatella group is composed of 61 species, of which only 11 occur in Brazil, mainly in the Atlantic Forest biome in the southeastern region. In order to reduce the Linnean and Wallacean shortfalls for the Smicridea Brazilian fauna, we diagnose, describe, and illustrate males of six new species in the fasciatella group: Smicridea (Smicridea) blahniki Desiderio, Pes & Hamada sp. nov., S. (Smicridea) brevitruncata Desiderio, Pes & Hamada sp. nov., S. (Smicridea) caaguara Desiderio, Pes & Hamada sp. nov., S. (Smicridea) ipiranga Desiderio, Pes & Hamada sp. nov., S. (Smicridea) jeaneae Desiderio, Pes & Hamada sp. nov., and S. (Smicridea) polyacantha Desiderio, Pes &; Hamada sp. nov. Additionally, we provide distributional data for S. (Smicridea) albosignata Ulmer, 1907, S. (Smicridea) bivittata (Hagen, 1861), S. (Smicridea) erecta Flint, 1974, S. (Smicridea) obliqua Flint, 1974, S. (Smicridea) paranensis Flint, 1983, and S. (Smicridea) sattleri Denning & Sykora, 1968. The number of S. (Smicridea) species in Brazil increases from 21 to 27 and Smicridea is recorded from the states of Acre, Amapá, and Sergipe for the first time.
Selizitapia gen. nov. (Hemiptera: Fulgoromorpha: Flatidae) from tapia woodlands of Madagascar
(2021)
A new monotypic genus of flatid planthoppers (Hemiptera: Fulgoromorpha: Flatidae), Selizitapia gen. nov., is described for Selizitapia pennyi gen. et sp. nov. (type species) from the island of Madagascar. Habitus, male and female external and internal genital structures of the new species are illustrated and compared with similar taxa. Selizitapia pennyi gen. et sp. nov. is endemic to Madagascar where it is known to date only from one locality in the Central Plateau and is associated with tapia woodland formation.
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 new South American leafhopper genera of the tribe Gyponini are proposed: Beltrana gen. nov. based on Beltrana reticulata gen. et sp. nov. from French Guiana, Fulana gen. nov. based on Fulana brasiliensis gen. et sp. nov. from Brazil, and Sicrana gen. nov. based on Sicrana plana gen. et sp. nov. from Brazil and Ecuador. Diagnoses, detailed descriptions, and illustrations are provided for each taxon, as well as comparisons with closely related genera. In addition, the following synonyms are proposed: Freytagana DeLong, 1975 as a junior synonym of Marganana DeLong, 1948 and F. gibsoni DeLong, 1975 as a junior synonym of M. (Marganana) mexicana DeLong & Freytag, 1963. Chilella DeLong & Freytag, 1967 is transferred from Gyponini to Selenomorphini Evans, 1974.
The planthopper genus Arcofaciella Fennah, 1956 (Hemiptera: Fulgoromorpha: Delphacidae) is reviewed. Four species are recognized, of which A. obflexa Guo & Liang, 2005 and A. verrucosa Fennah, 1956 are redescribed, and one new species, A. indiana sp. nov., is described. Habitus photos for adults and illustrations of male genitalia (excluding A. penangensis (Muir, 1919)) are given. A key for identifying the species of Arcofaciella is also provided.
The Brazilian endemic irroratus species group of the genus Inca (Scarabaeidae, Cetoniinae) is defined and described. This species group is composed of Inca irroratus Chevrolat, 1833 and two new species: I. axeli sp. nov. and I. neglectus sp. nov. One new synonym is proposed: I. irroratus Chevrolat, 1833 = I. burmeisteri Burmeister, 1844 syn. nov. To guarantee nomenclatural stability, a neotype is designated for I. irroratus and a lectotype for I. burmeisteri. A key to all species of Inca and a map with the distribution of the irroratus species group are provided.
Susamyia Ziegler & Gilasian gen. nov. and its type species Susamyia mira Ziegler & Gilasian gen. et sp. nov. are described from southwestern Karkheh National Park and southeastern Jazmourian Wetland of Iran. Drawings of terminalia and head of the male as well as images of habitus, head and egg are provided. Susamyia gen. nov. is incorporated into the identification key to the Palearctic tachinid genera of Tschorsnig & Richter (1998). The systematic position of Susamyia gen. nov. in the tribe Goniini (Exoristinae) is discussed in light of molecular analyses based on the ribosomal genes 16S, 18S and 28S, and the egg type of females. The morphology of the microtype eggs was studied and compared with that of other Goniini, but proved too unreliable to be included in the phylogenetic analysis. Susamyia gen. nov. is believed to be most closely related to the goniine genera Gymnophryxe Villeneuve, 1922, Palesisa Villeneuve, 1929 and Prosopodopsis Townsend, 1926.
Taxonomic review of the genus Erythrocricus Schubart, 1962 (Diplopoda, Spirobolida, Rhinocricidae)
(2021)
We review the genus Erythrocricus Schubart, 1962 based on the type material of the species Erythrocricus sanguineostriatus (Schubart, 1962). We propose a new diagnosis, redescribe the type species, and propose a new synonymy and a new combination. In addition, a male-based key to both species recognized, including Erythrocricus electrofasciatus (Schubart, 1957), comb. nov. ex. Rhinocricus, is given.
The genus Miridiba Reitter, 1902, of phytophagous chafers from Asia, is revised based on external morphological and genital (male and female) characters. In this study, a total fifty-eight species of Miridiba were examined, and the genus is redescribed. Male genital characters of Miridiba, especially the morphology of parameres and endophallus, are studied in depth herein. The female genitalia of Miridiba are studied and described in detail for the first time. According to genital characters, nine genital morphotypes, including fifty-four species, are established under the genus Miridiba. Sixty-seven type specimens are studied. Miridiba gressitti (Frey, 1970) comb. nov., Miridiba borneensis (Moser, 1918) comb. nov., Miridiba coxalis (Arrow, 1944) comb. nov., Miridiba rugaticollis (Moser, 1913) comb. nov., Miridiba nigrescens (Moser, 1916) comb. nov., Miridiba scutata (Reitter, 1902) comb. nov., Miridiba ciliatipennis (Moser, 1903) comb. nov. and Miridiba brunneipennis (Moser, 1916) comb. nov. are transferred from Holotrichia. Holotrichia dalatensis Frey, 1970 is transferred to Miridiba as a synonym of Miridiba sinensis (Hope, 1842). Four junior subjective synonyms are proposed: Miridiba pilosella (Moser, 1908) (= Holotrichia formosana Moser, 1909), Miridiba sinensis (= Holotrichia dalatensis Frey, 1970), Miridiba scutata (= Holotrichia scutulata Dalla Torre, 1912 and Miridiba lassallei Keith, 2010). Miridiba frontalis (Fairmaire, 1886) is resurrected as a valid species. A key to 51 of the 58 valid species of Miridiba is presented.
Comanopa Blocker, 1979 and Gehundra Blocker, 1976 are small and poorly known genera of leafhoppers, previously comprising four and five species, respectively. In this study, two new species are proposed: Comanopa mananciensis sp. nov. from the state of Paraná, Southern Brazil, and Gehundra cristalinensis sp. nov. from the state of Mato Grosso, Centralwestern Brazil. The male of Gehundra sordida (Baker, 1900) is studied by the first time. Detailed descriptions and illustrations of males and females are provided and keys to males of Comanopa and Gehundra are given.
Integrative taxonomy was employed to exploit the differences between the known Metaphire anomala (Michaelsen, 1907) and other specimens collected in Vietnam. The results brought to light two new species, namely Metaphire iranomala sp. nov. and Metaphire decemtheca sp. nov. The former is easily recognised by having male pores on xix and four pairs of spermathecal pores on 5/6/7/8/9 while the latter is distinguished by having five pairs of spermathecal pores on 4/5/6/7/8/9. The K2P distances of the fragment of the cytochrome c oxidase subunit I (COI) gene are 13.1% between M. iranomala sp. nov. and M. anomala (Michaelsen, 1907) and 18% between M. decemtheca sp. nov. and Metaphire grandiverticulata Nguyen & Lam, 2017. The intraspecific divergences are 1.5%–10.6% for M. iranomala sp. nov. and 2.1%–11.4% for M. decemtheca sp. nov.
The enigmatic millipede assassin bug genus Xenorhyncocoris Miller, 1938 is revised. Previously known species, X. caraboides Miller, 1938, X. princeps Miller, 1949 and X. schoenitzeri Putshkov & Bérenger, 1999, are diagnosed and photographed. A new species, X. attractivus sp. nov., is described based on male and female specimens from northeastern Borneo. The male of Xenorhyncocoris is reported for the first time, revealing the extreme sexual dimorphism present in the genus. The diagnosis of Xenorhyncocoris is extended in order to make it applicable to the new discovery, and a female-based key to species of the genus is updated. Relationships among Xenorhyncocoris and Vilius Stål, 1863, Neozirta Distant, 1919 and Schottus Distant, 1902 are briefly discussed.
The taxonomic status of the widely distributed freshwater crab Potamonautes lirrangensis (Rathbun, 1904) sensu lato is revised because morphological and molecular evidence indicates that this taxon is a complex comprising more than one species. Four taxa are now recognized: Potamonautes lirrangensis (Rathbun, 1904) s. str. and P. kisangani sp. nov. from the Middle Congo River in Central Africa, P. amosae sp. nov. from the drainages of Lakes Kivu and Tanganyika, and P. orbitospinus (Cunnington, 1907) from Lake Malawi which had been previously synonymised with P. lirrangensis s. lat. Diagnoses, illustrations and distribution maps are provided for each of these taxa and they are compared to similar species from Central and Southern Africa.
The genus Microplitis Förster, 1862 (Hymenoptera, Braconidae, Microgastrinae) was studied from northern Iran. Specimens were collected using Malaise traps during 2010–2011. A total of 13 species were collected and identified, of which six species are recorded for the first time from Iran: M. cebes Nixon, 1970, M. docilis Nixon, 1970, M. eremitus Reinhard, 1880, M. kaszabi Papp, 1980, M. pallidipennis Tobias, 1964 and M. varipes (Ruthe, 1860). Two species M. kaszabi and M. pallidipennis are new records for the west Palaearctic region. A new species, Microplitis alborziensis Abdoli & Talebi sp. nov., is described and illustrated. The number of species of Microplitis in Iran is now raised from 17 to 24. A faunistic list, an identification key to all known Iranian species and brief diagnoses and illustrations for all species that have been collected in this study are provided. The validity of the new species is supported by DNA barcoding.
