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
