Out of the Palaearctic: the Helophorus water beetles of the Afrotropical Region (Coleoptera: Helophoridae) David T. Bilton Helophorus Fabricius, 1775 (Coleoptera: Hydrophiloidea: Helophoridae) is an old and largely Holarctic genus of beetles, with most extant diversity concentrated in the Palaearctic. As with a number of primarily northern temperate lineages, the genus has colonised the Afrotropical Region, with species…

Scaphobaeocera setosa sp. nov., an unusual Scaphidiinae (Coleoptera: Staphylinidae) with elongate tarsal setae from China Ivan Löbl, Vivien Cosandey A new species of Scaphobaeocera Csiki, 1909 from Yunnan, China, S. setosa sp. nov., is described. It is unique in having strongly enlarged male protarsomeres with long oblique setae, forming a fan-like structure. The new species may be also readily distinguished from its congeners by its…
ERRATUM: ZHANG W.-X. & YIN Z.-W. 2023: Feabatrus gen. nov., a conspicuous new genus of Batrisitae from Myanmar and China (Coleoptera: Staphylinidae: Pselaphinae). Acta Entomologica Musei Nationalis Pragae 63 (1): 165–175. https://doi.org/10.37520/aemnp.2023.008
Two new sympatric species of Songius from Mount Fanjing, Southwest China (Coleoptera: Staphylinidae: Pselaphinae) Zi-Wei Yin, Zheng-Kun Hu The ant-loving beetle genus Songius Yin & Li, 2010 (Coleoptera: Staphylinidae: Pselaphinae: Batrisini) is rarely collected due to a cryptic myrmecophilous lifestyle, and its diversity remains insufficiently explored. Here we describe two new sympatrically distributed species from Mount Fanjing,…
Larval morphology of Crephelochares and Peltochares (Coleoptera: Hydrophilidae) Yusuke N. Minoshima, Martin Fikáček, Hsing-Che Liu The larval morphology of Crephelochares Kuwert, 1890 and Peltochares Régimbart, 1907 is described in detail based on specimens of C. abnormalis (Sharp, 1890) and P. atropiceus (Régimbart, 1903) collected in Taiwan; the chaetotaxy of the head capsule and head appendages of both genera is…
Discovery of a troglomorphic trechine beetle from the Ryukyu Archipelago, Southwestern Japan (Coleoptera: Carabidae: Trechinae) Kazuki Sugaya, Showtaro Kakizoe, Sohei Ooka, Hisao Tamura, Shinzaburo Sone A new genus and new species of Trechina (Coleoptera: Carabidae: Trechinae: Trechini), Ryukyuaphaenops pulcherrimus gen. & sp. nov. is described from the Ryukyu Archipelago, Japan. This is the first troglomorphic Carabidae in the Ryukyus and probably the most cave-adapted beetle in Japan.…
Description of one new genus and two new species of Apomecynini (Cerambycidae: Lamiinae) from Mexico Oscar Pérez-Flores, Emmanuel Arriaga-Varela, José Luis Navarrete-Heredia, Antonio Santos-Silva The knowledge of the diversity of leaf litter cerambycid fauna is limited, particularly in the Neotropics, where several species likely remain unreported. Most of these small and apterous beetles commonly belong to the tribe Apomecynini (Cerambycidae: Lamiinae). Herein, one new genus and two new…
First record of the tribe Oecleini in Australia (Hemiptera: Auchenorrhyncha: Fulgoromorpha: Cixiidae) with the description of a new genus and species Werner E. Holzinger, Birgit Löcker A new genus and species, Apollo maculiceps gen. & sp. nov., in the planthopper family Cixiidae is described from south Western Australia. It can be distinguished from all other Australian Cixiidae by the presence of a denticle on the distal part of the fore coxa, a character that is shared…
A review of Lasioglossum (Leuchalictus) in Taiwan (Hymenoptera: Apoidea: Halictidae) Ryuki Murao, Wen-Chi Yeh, Sheng-Shan Lu The Taiwanese bee species of the subgenus Leuchalictus Warncke, 1975 of the genus Lasioglossum Curtis, 1833 are revised. Three species are recognised, Lasioglossum formosae (Strand, 1910), Lasioglossum subopacum subopacum (Smith, 1853), and one new species, L. subinoum sp. nov., which was…
Chalarus (Diptera: Pipunculidae) of Colombia, with description of two new species and an updated key to males of the Neotropical species Yardany Ramos-Pastrana, Dayse W. A. Marques, José Albertino Rafael Chalarus Walker, 1834 (Diptera: Pipunculidae: Chalarinae) has a cosmopolitan distribution, with 11 known species in the Neotropical Region, but none recorded in Colombia. Two new species of Chalarus are described from Colombia, namely Chalarus boyacensis sp. nov. (type locality: Cabaña Chaina,…
Rehabilitation of Mormoschema (Hemiptera: Heteroptera: Pentatomidae): generic status restituted and tribal placement revised S. Salini, Petr Kment, Gerasimos Cassis Tolumnia immaculata Distant, 1900 (Hemiptera: Heteroptera: Pentatomoidea: Pentatomidae: Pentatominae) is redescribed based on the study of primary types and additional specimens from India and Sri Lanka. This species is found to not be congeneric with the rest of Tolumnia Stål, 1868, including the…
Integrative taxonomy of Central European Planetella (Diptera: Cecidomyiidae) indicates high species diversity, intraspecific variation and low host specificity Jan Ševčík, Heikki Hippa, Nikola Burdíková, Kryštof Sopuch, Marcela Skuhravá, Hans H. Bruun A first attempt is made to revise the European species of the gall midge genus Planetella Westwood, 1840 (Diptera: Cecidomyiidae), with a focus on the fauna of the Czech Republic, Slovakia and Denmark. A total of 19 species are recognized based on unique DNA sequences, of which…
