Terryerwinia gen. n.

Diagnosis. Belonging in the Epipsocidae . Five distal labral sensilla, almost in line: one central placoid, flanked by one trichoid and one placoid. Without row of cuticular cones on setal bases of fore­ and hind­femora. Wing venation caeciliusid, hindwing Rs­M fused basally for a distance. Clunium slightly projected posteriorly in area over epiproct. Phallosome simple,semi­closed anteriorly, without external parameres, with lateral struts slender, with a subquadrate apical projection, flanked by straight, acuminate projections, directed outwards. Endophallus constituted by a dense radula, formed by numerous individual corns. Hypandrium with distinct, postero­lateral prominences, bearing each a setal field. Gonapophyses with v1 absent, v3 an elongate, setose lobe on side of v2. Ninth sternum complex, with a well defined central piece. Differs from the other epipsocid genera with caeciliusid venation ( Bertkauia , Epipsocopsis , Epipsocus , Heteroepipsocus , Mesepipsocus , Rogojiella , and Spordoepipsocus ), by the posterior lateral projections of the phallosome, the posterior hypandrial prominences and absence of external parameres in the males, and in the females by the lack of v1 and structure of the ninth sternum.

Type species. Terryerwinia acutiphallica
