Papillopsocus gen. n.

Diagnosis. Belonging in the Epipsocidae . Five distal labral sensilla, almost in line: a central placoid, with one pair trichoid­placoid on each side. Wing venation caeciliusid (FW Rs 2­branched, M 3­branched; HW Rs 2­branched, M unbranched). Hindwing Rs­M fused basally for a distance. Phallosome semi­closed anteriorly, aedeagal arch stout, slightly projected apically, without external parameres; a distinct endophallus, formed by an elongate sheet, posteriorly concave, bearing a field of papillae on distal third, not reaching the posterior border; strongly pigmented on the sides, underlaid by two elongate, slender, distally acuminate sclerites. Endophallic sheet basally with a large, rounded, papillose pigmented body on each side. Female gonapophyses without v1, v3 an elongate, setose lobe on side of v2; ninth sternum thick, pigmented. Differing from the described epipsocid genera ( Bertkauia , Cubitiglabra , Dichoepipsocus , Dicropsocus , Epipsocopsis , Epipsocus , Goja , Heteroepipsocus , Hinduipsocus , Ianthorntonia , Liratepipsocus , Mesepipsocus , Metepipsocus , Odontopsocus , Rogojiella , Spordoepipsocus , and Valvepipsocus Li ), by the combination of wing venation and genital characters listed above; the phallosome structure is unique in the family.
