Abstract: Two assassin bugs, Ectomocoris cordiger Stål, 1867 and E. fenestratus (Klug, 1830) (Hemiptera: Heteroptera: Reduviidae: Peiratinae), are redescribed. Ectomocoris picturatus Distant, 1919, syn. nov., is treated as a junior synonym of E. cordiger, and Pirates adjunctus Walker, 1873 is confirmed as a synonym of that species. Ectomocoris costatus Miller, 1954, syn. nov., is treated as a junior synonym of E. fenestratus. Types of all four nominal species were examined, and lectotypes of E. cordiger, E. picturatus, E. fenestratus and P. adjunctus are designated. Habitus images of the type specimens, figures of the male genitalia and a distribution map are also provided. The occurrence of E. fenestratus in Uganda is confirmed.

Löbl IvanOn the identity of Scaphidium grande, with resurrection of S. inimpressum and S. melanopus and description of two new species (Coleoptera: Staphylinidae: Scaphidiinae)Acta Entomologica Musei Nationalis Pragae 65(1): 15-20Abstract: Scaphidium grande Gestro, 1879, assumed to be widely distributed in Asia, has been misidentified. The range of this species is likely restricted to Borneo. Scaphidium grande is distinguished from allied species by the male genital characters, notably by the shape of the median lobe. Scaphidium grande var. inimpressum Pic, 1920 and S. grande var. melanopus (Achard, 1924), placed in synonymy by Löbl (1992, 2018), are resurrected as valid species. The lectotype is designated for Scaphidiolum grande var. melanopus Achard, 1924. Similar and obviously related species, Scaphidium metafasciatum sp. nov. from Taiwan and Scaphidium grandior sp. nov. from Thailand, are described.Published online: 9th March 2025
Chen Zhuo, Cai WanzhiThe second Malagasy species of Anacanthiocnemis (Hemiptera: Heteroptera: Reduviidae) with an updated key to the species of the genusActa Entomologica Musei Nationalis Pragae 65(1): 21-30Abstract: Based on the material collected from Toamasina, east Madagascar, we describe Anacanthiocnemis lihui sp. nov. as the second Malagasy representative of the genus Anacanthiocnemis Reuter, 1882 (Hemiptera: Heteroptera: Reduviidae: Stenopodainae). The new species presents relatively long postocular region of head, widely separated mandibular plates, and different armatures on the profemur, that allow it to be readily distinguished from its congeners. Illustrations and COI barcode of the new species as well as an updated key to the species of Anacanthiocnemis are provided. The known distribution records of Anacanthiocnemis are summarized, showing that the species of the genus occur mainly in tropical rainforests or savannas.Published online: 9th March 2025
Byeon Ui-Joung, Chandler Donald S., Leschen Richard A. B., Park Jong-SeokRevision of the New Zealand genus Euglyptus (Coleoptera: Staphylinidae: Pselaphinae) with eight new speciesActa Entomologica Musei Nationalis Pragae 65(1): 31-59Abstract: The New Zealand endemic genus Euglyptus Broun, 1893 (Staphylinidae: Pselaphi-
nae: Euplectitae) is revised. Eight new species are described: Euglyptus bifurcatus sp. nov., E. boreus sp. nov., E. dunedinensis sp. nov., E. latefossatus sp. nov., E. parvus sp. nov., E. punctatosimilis sp. nov., E. robertensis sp. nov., and E. waimatensis sp. nov. The following new synonyms are proposed: Euglyptus elegans Broun, 1893 = E. costifer Broun, 1893, syn. nov.; and E. punctatus Broun, 1893 = E. iracundus (Broun, 1893), syn. nov. Lectotypes are designated for E. abnormis Broun, 1921, E. punctatus Broun, 1893, and E. costifer Broun, 1893. Euglyptus now comprises 15 species; all taxa are (re)described, habitus and diagnostic characters are illustrated, and their distribution maps are provided. We also provide an identification key for the Euglyptus species.Published online: 6th April 2025
Bulirsch Petr, Magrini Paolo, Ho Bin-Hong, Fikacek MartinSpecies of the genus Reicheiodes from Taiwan (Coleoptera: Carabidae: Scaritinae)Acta Entomologica Musei Nationalis Pragae 65(1): 61-70Abstract: The species of the genus Reicheiodes Ganglbauer, 1891 from Taiwan are reviewed. The Taiwanese fauna consists of three species: Reicheiodes (Reichonippodes) kuankong sp. nov., R. (Reichonippodes) ursinus sp. nov., and R. (Reichonippodes) taiwanensis Bulirsch, 2018; the latter previously known in the female holotype only. All species are (re)described, diagnosed, their habitus and male genitalia are illustrated, and the body measurements are provided for the newly collected specimens of R. taiwanensis. Keys to all Taiwanese species, as well to all species of the subgenus Reichonippodes Dostal, 1993, are provided. DNA barcodes are provided for all three species and used to reconstruct the phylogenetic relationship of the species and to estimate their age. Both morphological and DNA data indicate that all three species are closely related and probably represent within-island radiation in the last 2.4 million years. All three species are allopatric, inhabiting the northern (R. kuankong), central (R. taiwanensis) and southern (R. ursinus) Taiwan. All specimens were sifted from the leaf litter of lowland to submontane (R. kuankong) or higher montane (R. taiwanensis and R. ursinus) broadleaf forests.Published online: 10th May 2025
Reshchikov AlexeyBylesia gen. nov., a new genus of Darwin wasp (Hymenoptera: Ichneumonidae) from the Eastern HimalayaActa Entomologica Musei Nationalis Pragae 65(1): 71-79Abstract: A new genus of Cremastinae (Hymenoptera, Ichneumonidae), Bylesia gen. nov., and its type species, B. brachyscleromamorpha sp. nov., are described from the Eastern Himalaya, Yunnan, China. The new taxa are illustrated, diagnosed, and their relationships are discussed.Published online: 3rd June 2025
Benda Daniel, Straka JakubA new species of the genus Eurystylops (Strepsiptera: Stylopidae) rediscovered after more than 100 years from Rophites bees (Hymenoptera: Halictidae)Acta Entomologica Musei Nationalis Pragae 65(1): 81-94Abstract: A new species of Strepsiptera of the genus Eurystylops Bohart, 1943 (Stylopidae) from the Western Palearctic Region is described based on the female cephalothorax. Eurystylops ogloblini sp. nov. represents the first species described from the host bee of the genus Rophi-
tes Spinola, 1808. We have found Rophites clypealis Schwammberger, 1976, R. hartmanni Friese, 1902 and R. quinquespinosus Spinola, 1808 to be hosts of this species. We summarize all known data on the distribution of the genus Eurystylops in the Western Palearctic Region which suggest a recent decline of these rare parasites. We consider their rarity to be a direct consequence of the threat to their hosts, which are oligolectic bees. We also provide the first evidence of the existence of males in the genus Eurystylops based on an empty male puparium, which was noticed more than 100 years ago in R. quinquespinosus. A detailed redescription of the female cephalothorax of Eurystylops oenipontana Hofeneder, 1949 is provided. Eurystylops oenipontana is recorded from the Czech Republic for the first time.Published online: 3rd June 2025
Gierlasiński Grzegorz, Dobosz Roland, Poźniak Aleksandra, Sitnik Michelle, Taszakowski ArturNotes on plant bugs from New Caledonia with descriptions of two new species of the genus Bolbomiris (Hemiptera: Heteroptera: Miridae)Acta Entomologica Musei Nationalis Pragae 65(1): 95-104Abstract: Two new species of Bolbomiris Hosseini & Cassis, 2019, B. picpinensis Gierlasiński & Taszakowski sp. nov. and B. koghi Gierlasiński & Taszakowski sp. nov., are diagnosed and described. Photographic images of habitus and male genital structures, as well as scanning electron micrographs of selected structures of these species, are provided. An updated key to the species of Bolbomiris is presented. Additionally, the paper also presents new localities of Bolbomiris cola Hosseini & Cassis, 2019, Bolbomiris samuelsoni Hosseini & Cassis, 2019, as well as Peritropis bicolor Gorczyca, 1999 and Kanakamiris krypton Cassis & Monteith, 2006 (Cylapinae), Fingulus novocaledonicus Stonedahl & Cassis, 1991 (Deraeocorinae), and Coridromius variegatus (Montrouzier, 1861) (Orthotylinae). The occurrence of scopula in Bolbomiris and other plant bugs is briefly discussed.Published online: 14th June 2025
