Jie, Lulan, Liang, Feiyang & Liu, Xingyue, 2022, Dipsocus gen. n.: A new bark louse genus of the tribe Thyrsophorini (Psocodea: Psocidae: Psocinae), with description of a new species from China, Zootaxa 5222 (1), pp. 94-100 : 95-96

Dipsocus gen. n.

Type species. Dipsocus fashengi sp. n.

Diagnosis. Forewing Sc ending free; Rs and M connected by a crossvein; areola postica nearly trapezoidal; cell m3 normal, not narrowed. Male genitalia: Hypandrium symmetrical, divided into two parts, basal part strongly sclerotized, distal part weakly sclerotized; phallosome ring-like, posteriorly closed. Female genitalia: Epiproct subtriangular; paraproct triangular; subgenital plate with short and distally rounded egg guide, pigmented area slightly sclerotized, roughly T-shaped, stem thread-like and distally bifurcated; gonapophyses: ventral valve slender, dorsal valve broad, pointed at tip, inner margin with strongly sclerotized area at base, external valve with triangular posterior lobe.

Distribution. China.

Remarks. The new genus can be easily distinguished from the other genera of Thyrsophorini by the male hypandrium divided into two parts, of which the basal part is strongly sclerotized but the distal part is weakly sclerotized; the pigmented area of the female subgenital plate stem is thread-like and distally bifurcated.

Etymology. From Greek “ Di- ” (meaning “two”) and “ Psocus ” in reference to the male hypandrium divided into two parts. Gender: Feminine.
