  A review of the genus Platydialepis Haupt (Hymenoptera, Pompilidae) of China, with description of four new species and key to the species Abstract The genus Platydialepis Haupt is a small genus of Pompilidae . Its members hunt spiders for larval provisioning. Studying this genus helps further enhance the understanding of biodiversity within this genus. The genus Platydialepis Haupt from China is reviewed. Four new species, Platydialepis bidentata Cui, Li & Ma, sp. nov ., P. flavipectoralis Cui, Li & Ma, sp. nov ., P. frontimaculata Cui, Li & Ma, sp. nov ., and P. prominula Cui, Li & Ma, sp. nov . are described. Additionally, P. ryoheii (Ishikawa, 1957) is reported as a first record from China. A key to Chinese species of the genus Platydialepis is provided.

New Theraphosinae from Ecuador: description of five species (Mygalomorphae, Theraphosidae, Romopelma, and Homoeomma) with the establishment of a new genus

Abstract

A review of specimens from the subfamily Theraphosinae in Ecuador resulted in the identification of five new species across three genera; from the genus Romopelma Peñaherrera-R et al., 2024, Romopelma chirapa sp. nov. (♂♀); from the genus Homoeomma, Homoeomma josti sp. nov. (♂♀). The female of Romopelma barrigae Peñaherrera-R et al., 2024, the type species of the genus, is described for the first time. The proposed synonymy of Homoeomma strabo (Simon, 1892) from Colombia with H. familiare Bertkau, 1880, from Brazil, is rejected. Additionally, one new genus is established, and three species are described: Yunka gen. nov., Y. suenos sp. nov. (♂♀), Y. guasaganda sp. nov. (♂♀), and Y. baboso sp. nov. (♂♀). SEM images of palpal bulb, and urticating setae are presented, and morphological nomenclature of palpal bulb keels is updated.
