A revision of the Larainae (Coleoptera, Elmidae) of Venezuela, with description of nine new species.

ABSTRACT: The species of the riffle beetle subfamily Larainae occurring in Venezuela are revised. Examination of 756 specimens yielded 22 species in nine genera occurring throughout the country. Seven species are newly recorded from the country: Phanoceroides sp. 1, Phanocerus clavicornis Sharp, 1882, Phanocerus congener Grouvelle, 1898, Pharceonus volcanus Spangler & Santiago-Fragoso, 1992, Disersus dasycolus Spangler & Santiago-Fragoso, 1992, Disersus chibcha Spangler & Santiago-Fragoso, 1987, and Disersus inca Spangler & Santiago-Fragoso, 1992. Nine species are found to be new to science, which are here described: Hexanchorus dentitibialis sp. n., H. falconensis sp. n., H. flintorum sp. n., H. homaeotarsoides sp. n., H. inflatus sp. n., Phanocerus rufus sp. n., Pharceonus grandis sp. n., Pharceonus ariasi sp. n., Potamophilops bostrychophallus sp. n. Additionally, a key to species, distribution maps, and photographs and genitalia illustrations are provided for all species.

Revision of the genus Limobius, with the description of a new species (Coleoptera, Curculionidae, Hyperini).

Project description:The new species, Limobius winkelmannisp. n. is described, keyed, and illustrated. This enigmatic new species has seven desmomeres as other Hyperini-species, but according to shape of elytra and aedeagus, which are typical for representatives of Limobius, it is treated in this genus. The actualised key and check-list of Limobius is presented. The taxonomical position and status of the genus Limobius within the tribe Hyperini is also discussed here.

Revision of the Theopea genus group (Coleoptera, Chrysomelidae, Galerucinae), part III: Descriptions of two new genera and nine new species.

Project description:This publication treats species within Theopea and closely allied genera that were not covered in the previous two revisions. Three species of Theopea Baly, 1864 are treated herein, with T. bicolor Kimoto, 1989 and T. mouhoti Baly, 1864 redescribed, and T. bicoloroides sp. nov. described. A new genus that we consider closely related to Theopea, Pseudotheopea gen. nov., is described. This new genus can be recognized with the presence of reticulate microsculpture on the vertex of the head and pronotum and presence of an apical spine on each metatibia. The following species are transferred to Pseudotheopea as new combinations: Theopea aeneipennis Gressitt & Kimoto, 1963, T. azurea Gressitt & Kimoto, 1963, T. clypealis Medvedev, 2015, T. nigrita Medvedev, 2007, T. smaragdina Gressitt & Kimoto, 1963, T. similis Kimoto, 1989, and T. subviridis Medvedev, 2012. Theopea subviridis Medvedev, 2012 is regarded as new synonym of Pseudotheopea similis (Kimoto, 1989). In addition, six new species of Pseudotheopea are described: P. boreri sp. nov. from India, P. gressitti sp. nov. from Philippines, P. hsingtzungi sp. nov. from Laos, P. kimotoi sp. nov. from Laos, Thailand, and Vietnam, P. leehsuehae sp. nov. from Laos, and P. sufangae sp. nov. from Taiwan. A second new genus regarded as closely related to Pseudotheopea, Borneotheopea gen. nov., can be recognized by possessing uniform antennae in both sexes and lacking an apical spine on each metatibia. Two new species of Borneotheopea are described from Borneo: B. jakli sp. nov. and B. kalimantanensis sp. nov.

Project description:Nine new species constituting the 'spiny' group of dragon millipedes are assigned to the new genus Spinaxytes Srisonchai, Enghoff & Panha, gen. n. Seven new species are described from Thailand: S.biloba Srisonchai, Enghoff & Panha, sp. n. and S.palmata Srisonchai, Enghoff & Panha, sp. n. from Surat Thani Province, S.hasta Srisonchai, Enghoff & Panha, sp. n. from Chumphon Province, S.krabiensis Srisonchai, Enghoff & Panha, sp. n. (type species) and S.sutchariti Srisonchai, Enghoff & Panha, sp. n. from Krabi Province, S.uncus Srisonchai, Enghoff & Panha, sp. n., and S.macaca Srisonchai, Enghoff & Panha, sp. n. from Phang Nga Province; as well as one from Malaysia, S.tortioverpa Srisonchai, Enghoff & Panha, sp. n., and one from Myanmar, S.efefi Srisonchai, Enghoff & Panha, sp. n. The new genus is endemic to South Myanmar, South Thailand, and Malaysia, and all new species are restricted to limestone habitats. All were exclusively found living on humid rock walls and/or inside small caves. Complete illustrations of external morphological characters, an identification key, and a distribution map are provided.

Taxonomic revision of the Afrotropical <i>Agabus raffrayi</i> species group with the description of four new species (Coleoptera, Dytiscidae).

Project description:We revise the Afrotropical Agabus raffrayi species group, motivated by the discovery of new diversity in Kenya and South Africa. Whilst Agabus is mainly a holarctic genus, the Agabus raffrayi group is restricted to high altitude regions of eastern Africa and temperate parts of South Africa, from where we describe the southernmost Agabus in the world. The following new species are introduced: Agabus anguluverpus sp. nov. from Mount Kenya in central Kenya, Agabus austellus sp. nov. a widespread species in South Africa, Agabus riberae sp. nov. from the Kamiesberg and northeastern Cederberg ranges in the Northern and Western Cape Provinces of South Africa and Agabus agulhas sp. nov. from the Agulhas Plain, Western Cape Province, South Africa. We provide a distribution map, a determination key for males, quantitative measurements of diagnostic characters, habitus photos and detailed photos of male genitalia for all described species in the group, as well as images of diagnostic characters and habitats. The presence or absence of an elongated section between the subapical broadening and the base of the apical and subapical teeth of the male aedeagus is a useful novel character, first revealed by our study. In contrast with the most recent revision of Afrotropical Agabus, we show that Agabus ruwenzoricus Guignot, 1936 is restricted to eastern Africa; South African records of this species having been based on misidentifications, no species of the group being common to southern and eastern Africa. We speculate that the raffrayi group may display phylogenetic niche conservatism, being restricted, as an originally temperate taxon, to higher elevations in tropical eastern Africa, but occurring at lower altitudes in temperate South Africa.

Revision of the genus Phloeoditica Schedl - with description of two new genera and two new species in Phloeosinini (Coleoptera, Curculionidae, Scolytinae).

Project description:The genus Phloeoditica Schedl currently includes four species from Southeast Asia. These species vary substantially in important morphological characters and indicate the existence of multiple genera for these species. A revision based on morphological and in part molecular data resulted in the transfer of Phloeoditica setosa to Pseudoxylechinus the erection of a new genus Asiophilus for Phloeoditica phloeosinoides and a new species Asiophilus macropunctatus from Vietnam. Another new genus with affinities to Phloeoditica is described based on the new species Microditica uniseriata from Thailand. The new genera are included in a revised key to the tribe Phloeosinini.

A taxonomic revision of the Cymindis (Pinacodera) limbata species group (Coleoptera, Carabidae, Lebiini), including description of a new species from Florida, U.S.A.

Project description:The Cymindis (Pinacodera) limbata species group (Coleoptera, Carabidae, Lebiini) is a precinctive New World taxon with ranges extended from portions of temperate southeastern Canada and the U.S.A. through the montane regions of Mexico, south to the Isthmus of Tehuantepec. The group is distinguishable from all other members of the subgenus Pinacodera by males possessing a distinctive sclerite (endophallic plate) at the apex of the endophallus. In the past, a lack of material and misunderstandings of range of variation within species have contributed to confusion about how many species there really are. This revision of the limbata species group includes a classification, a key to groups within the subgenus Pinacodera and species within the limbata group, descriptions of species, re-rankings and new synonymies. In total 10 taxa are treated, with 6 new synonyms proposed, 1 new combination introduced and 1 new species described: Cymindis (Pinacodera) rufostigma (type locality: Archbold Biological Station, Highlands County, Florida, U.S.A.). Each taxon is characterized in terms of structural features of adults, habitat, geographical distribution, and chorological affinities. Available ecological information and treatments of variation are included.
