  Hidden in the woods: A new species of Hexura (Araneae, Mygalomorphae, Antrodiaetidae) from a highly restricted range in Idaho Abstract A new species of Hexura Simon, 1885 is described from a very restricted geographic range in the Rocky Mountains of Idaho, 500 km east of the previously known distribution of the genus in the Coastal Ranges and western Cascade Mountains of Oregon and Washington. This work provides the first taxonomic information for this group in almost 50 years, including a phylogenomic framework for the genus within the mygalomorph superfamily Atypoidea , based on Ultraconserved elements ( UCEs ). Hexura vandal sp. nov . can be distinguished from the other two described species by a combination of morphological, molecular, and geographic characteristics. Lastly, we discuss the need for conservation actions to secure the survival of the species.

Scorpions of Angola (Arachnida, Scorpiones). Part I. Family Buthidae, with descriptions of two new species.

Abstract

All scorpion species of the family Buthidae known from Angola are listed, with color photographs and maps of their distribution. Diagnosis of Babycurus ansorgei Hirst, 1911 is revised; its male is described for the first time. Babycurus crassicaudatus Roewer, 1952, is revalidated (it was erroneously synonymized with B. ansorgei, since the females of both species are morphologically almost identical). Uroplectes angolensis sp. n. and U. xavieri sp. n. are described from Angola. Validity of Uroplectes ngangelarum Monard, 1930 is confirmed as different from U. planimanus (Karsch, 1879); its lectotype is designated. Lectotype is also designated for Uroplectes planimanus kuanyamarus Monard, 1937. Female of Uroplectes ebogo Kovařík et al., 2024 from Cameroon is recorded for the first time; its pectines are imaged (Fig. 603). Uroplectes machadoi Lourenço, 2000 is for the first time listed from Congo (Brazzaville).
