A new genus of the family Alexarasniidae (Insecta: Embiida) from the Triassic of Kyrgyzstan

Abstract

The Recent webspinners (Embiida = Embioptera) comprise a small order of insects; there are about 400 species distributed mainly in tropical and subtropical regions (Miller et al., 2012). They are gregarious, living subsocially in galleries of fine silk which they spin from glands on their forelegs (Edgerly et al., 2002). The webspinner lineage is traceable back via Middle Cretaceous Sorellembiidae, Jurassic Sinembiidae and Late Permian–Triassic Alexarasniidae to the Early–Middle Permian Atactophlebiidae (Engel & Grimaldi, 2006; Huang & Nel, 2009; Shcherbakov, 2015).
