The hypnorum-complex of bumblebees (in the genus Bombus Latreille, 1802) has been interpreted as consisting of a single widespread Old-World species, Bombus hypnorum (Linnaeus, 1758) s. lat., and its closely similar sister species in the New World, B. perplexus Cresson, 1863. We examined barcodes for evidence of species’ gene coalescents within this species complex, using the closely related vagans-group to help calibrate Poisson-tree-process models to a level of branching appropriate for discovering species. The results support seven candidate species within the hypnorum-complex (Bombus taiwanensis Williams, Sung, Lin & Lu, 2022, B. wolongensis Williams, Ren & Xie sp. nov., B. bryorum Richards, 1930, B. hypnorum, B. koropokkrus Sakagami & Ishikawa, 1972, and B. hengduanensis Williams, Ren & Xie sp. nov., plus B. perplexus), which are comparable in status to the currently accepted species of the vagans-group. Morphological corroboration of the coalescent candidate species is subtle but supports the gene coalescents if these candidates are considered near-cryptic species.
Revision of the tribe Pogonini (Coleoptera, Carabidae, Trechinae) from the Ibero-Balearic region
(2022)
In the Iberian Peninsula and the Balearic Islands, Pogonini (Coleoptera, Carabidae) is the least species-rich tribe of Trechinae. Nevertheless, the taxon is relatively poorly studied in this territory, and the available records are mostly published in old and/or faunistic works. The present study provides a taxonomic revision of the 3 genera and 11 species of Pogonini occurring in the Ibero-Balearic region, with an identification key, diagnoses and illustrations of their external morphology and aedeagus. The chorology of the species was also studied, and was assessed by obtaining precise records from published papers and the collection localities of the examined material. These data were used to make updated distribution maps (with several new occurrence points) that reveal a strong regionalization of the tribe in the Ibero-Balearic territory. The species occur in humid and saline environments, especially along the meridional and Mediterranean coasts of the Iberian Peninsula and in inner arid localities of eastern Spain. This result agrees with the widely accepted halobiont condition of the group. However, sampling bias must be considered, and new records are expected to be provided from future revisions of collections and new samplings.
An annotated list, including information on type species, distribution, and number of species, is provided for all of the non-flea-beetle galerucine genera known to occur in the New World (tribes Galerucini, Metacyclini, and Luperini). A diagnostic key to the genera is provided. Habitus illustrations are provided for most genera. The following new genera are proposed: Amplioluperus gen. nov., Cornuventer gen. nov., Geethaluperus gen. nov., Megarhabda gen. nov., Mexiluperus gen. nov., Monoaster gen. nov., Pyesexora gen. nov., Texiluperus gen. nov., Trachyelytron gen. nov. and Yingabruxia gen. nov. The following new taxonomic placements are proposed: Microbrotica Jacoby, 1887 is transferred from the tribe Metacyclini to the section Diabroticites Chapuis, 1875 (tribe Luperini, subtribe Diabroticina Chapuis, 1875); Pteleon Jacoby, 1888 is transferred from the section Exosomites Wilcox, 1973 (tribe Luperini, subtribe Luperina Gistel, 1848) to the section Scelidites Chapuis, 1875 (subtribe Luperina). The following new combinations are proposed: Luperodes histrio Horn, 1895, Luperus maculicollis LeConte, 1884, and Scelolyperus cyanellus Horn, 1895 are transferred from Pseudoluperus Beller & Hatch, 1932 to Amplioluperus; Luperodes tuberculatus Blake, 1942 is transferred from Pseudoluperus to Cornuventer; Luperus flavofemoratus Jacoby, 1888 is transferred from Pseudoluperus to Geethaluperus; Trirhabda obscurovittata Jacoby, 1886 is transferred from Trirhabda LeConte, 1865 to Megarhabda; Cneorane nigripes Allard, 1889 is transferred from Scelida Chapuis, 1875 to Metacycla Baly, 1861; Luperodes wickhami Horn, 1893 and Luperus dissimilis Jacoby, 1888 are transferred from Pseudoluperus to Mexiluperus; Scelolyperus tenuimarginatus Bowditch, 1925, is transferred from Scelida to Mimastra Baly, 1865 and is synonymized with Mimastra semimarginata Jacoby, 1886 syn. nov.; Pseudoluperus fulgidus Wilcox, 1965 and Pseudoluperus linus Wilcox, 1965 are transferred from Pseudoluperus to Monoaster; Crioceris detrita detrita Fabricius, 1801, Malacosoma detrita laevicollis Jacoby, 1887, Pyesia detrita meridionalis Bechyné, 1958, Pyesia elytropleuralis elytropleuralis Bechyné, 1958, and Pyesia elytropleuralis subalutacea Bechyné, 1958 are transferred from Pyesia Clark, 1865 to Pyesexora; Luperodes spretus Horn, 1893 and Luperodes texanus Horn, 1893 are transferred from Pseudoluperus to Texiluperus; Chthoneis smaragdipennis Jacoby, 1888 is transferred from Platymorpha Jacoby, 1888 to Trachyelytron; Luperus albomarginatus Jacoby, 1888 is transferred from Pseudoluperus to Trichobrotica Bechyné, 1956; and Galleruca sordida LeConte, 1858, Monoxia apicalis Blake, 1939, Monoxia batisia Blatchley, 1917, and Monoxia brisleyi Blake, 1939 are transferred from Monoxia LeConte, 1865 to Yingabruxia; all comb. nov. Pseudoluperus decipiens (Horn, 1893), originally described in Scelolyperus Crotch, 1874, is reduced to a junior synonym of Pseudoluperus longulus (LeConte, 1857), syn. nov. Trachyscelida dichroma Viswajyothi & Clark is proposed as a nom. nov. for Racenisa bicolor Bechyné, 1958 (not Agelastica bicolor LeConte, 1884), as both species are currently placed in the genus Trachyscelida Horn, 1893.
The taxonomic status of the nominal taxon Dryophis prasinus flavescens Wall, 1910 is reevaluated herein. Based on molecular data generated from fresh collections of Ahaetulla prasina (H. Boie in F. Boie, 1827) auctorum from Northeast India and, additionally, morphological data from museum specimens originating from the same areas, we resurrect this taxon as Ahaetulla flavescens (Wall, 1910) comb. nov. We clarify the status, identity and locations of its type specimens, rediscover, redescribe and illustrate those specimens and also designate a lectotype in order to effect a proper taxonomic redefinition of this nominal taxon. We provide further details on the morphology and diagnosis of this species and elucidate its phylogenetic position. We also provide a summary of the natural history and distribution of this species. Adding to the known cryptic diversity and genetic divergence within Southeast Asian populations, this work also hints at the need for a taxonomic revision of the A. prasina complex. This work complements a previous study on the A. prasina complex focusing on populations in Indonesia. Taken together, these two studies represent phylogenetic reconstructions from different populations of the A. prasina complex across its distribution range, on the Asian mainland and the surrounding islands.
