Genus Cormopsocus Yoshizawa & Lienhard, 2020 View in CoL
Type species. Cormopsocus groehni Yoshizawa & Lienhard, 2020 View in CoL .
Revised diagnosis (after Yoshizawa & Lienhard, 2020). Macropterous. Head: vertex strongly expanded dorsally, quadrate-shaped with rounded edge apically and laterally; postclypeus well bulged, bottom half exceeding bottom line of head capsule and located in front of oral region; lacinia developed; maxillary palpus four-segmented, last segment long and tapering apically; labial palpus two-segmented, distal segment rounded; antenna long with variable length, flagellum composed of numerous short flagellomeres (over 20), each about as long as or shorter than length of pedicel, with possibility of secondary annulations on some distal segments. Legs: tarsi three-segmented; pretarsal claws symmetrical, with preapical tooth. Wings glabrous. Forewing: anterior and posterior margins almost parallel; Sc well-developed and strongly arched, ending at R 1 vein; R 1 -Rs crossvein present; A 2 vein absent; stigmapophysis absent; veins CuP and A 1 ending separately on wing margin; in-flight wing-coupling structure simple, composed of separate and almost straight spines. Hind wing: Sc vein welldeveloped, ending in distal part of anterior wing margin or not; A 2 vein present. Terminalia: paraproct lacking anal spine; paraproctal trichobothrial field well-developed; paramere well-developed and broad.
Remarks. The shape of the vertex is an additional diagnostic trait found in both species of Cormopsocus ; whereas, the characters ‘length of the antenna compared to the forewing’ and ‘vein Sc reaching the distal part of anterior wing margin’ are variable. This updated diagnosis take these three new features into account. We refrain from establishing a new genus for Cormopsocus neli for the time being since both species are based on single specimens, and no other genera are known to this family.
