Abstract

The genus Khasurtyphilus Lyubarsky & Perkovsky, gen. nov. (type species Khasurtyphilus storozhenkoi Lyubarsky, Vasilenko, Legalov & Perkovsky, sp. nov.) is described from the Lower Cretaceous of Western Transbaikalia, Russia. The new genus is morphologically similar to the extinct genus Turgaphilus Lyubarsky et Perkovsky, 2025 (Lower Cretaceous, Eastern Transbaikalia) but differs from it in having: a pronotum with a lateral tooth in the posterior third of its length, tarsomere 1 shorter than tarsomeres 2 and 3 combined, tarsomere 5 longer than tarsomere 1, and narrowly separated metacoxae. The genus Khasurtyphilus differs from the genus Isocryptophilus Li & Cai, 2024 (Erotyloidea) in: temples present; lateral margin of the pronotum with a tooth; epipleura complete; tarsomere 3 longer than tarsomere 2.
