Type species.

Parasogata binaria sp. n.

Diagnosis.

This genus is readily recognized by its large size and vertex, pronotum and mesonotum bearing an uninterrupted white fascia. The genus is most similar to Sogata Distant, 1906 but separately by the phallus being up-curved (down-curved in Sogata ( Ding 2006: figs 281-283)), with a row processes at subapically (without process in Sogata ).

Description.

General color of male yellowish white to brown (Figs 9-12, 35-38). Vertex, pronotum and mesonotum with an uninterrupted white fascia (Figs 9, 35). Vertex, frons, face, antennae yellowish brown to yellowish white (Figs 9-12, 35-38). Pronotum and mesonotum yellowish white (Figs 13, 39). Forewings and hindwings hyaline (Figs 9-12, 35-38). Legs yellowish white (Figs 10, 36). Abdomen yellow (Figs 10, 36). Head including eyes narrower than pronotum (Figs 13, 15, 39, 41). Vertex subquadrate, anterior margin arched, lateral carinae with slightly concave, submedian carinae uniting at apex. Frons with single median carina, longer in middle line than wide at widest part, widest at apex (Figs 14, 16, 40, 42). Y-shaped carina feeble (Figs 13, 15, 39, 41). Antennae cylindrical, with basal segment shorter than second, reaching frontoclypeal suture (Figs 14, 16, 40, 42). Pronotum with lateral carinae almost attaining hind margin (Figs 13, 15, 39, 41). Posttibial spur with 29-32 distinct teeth along hind margin.

Male genitalia.

Anal segment collar-shaped, lateroapical angles produced into processes (Figs 24-25, 50-51). Pygofer in profile wider ventrally than dorsally, laterodorsal angles not produced, in posterior view with opening wider than long, lateral margins well defined, lateral quadrate areas strongly sclerotized, medioventral process absent (Figs 21-23, 47-49). Diaphragm broad (Figs 23, 49). Aedeagus long, tubular, with a row processes at subapically, slightly upward apically (Figs 26, 52). Genital styles simple, widely divergent apically (Figs 27-28, 53-54). Suspensorium large (Figs 29, 55).

Etymology.

This generic name " Parasogata " refers to its strong similarity to Sogata . The name is to be treated as feminine.

Distribution.

China.

Remarks.

The genus Parasogata gen. n. resembles Sogata Distant, 1906, Neometopina Yang, 1989, Neunkanodes Yang, 1989 and Lisogata Ding, 2006 in vertex, pronotum and mesonotum with an uninterrupted white fascia, frons with median carina single (Figs 1-8), but differs from these genera by anal segment with two pairs of processes, or with a pair of forked processes (without process in Lisogata ); aedeagus not forked at half of apex (with forked at half of apex in Neometopina and Neunkanodes ); aedeagus with processes and decurved dorsad apically (without process and decurved ventrad apically in Sogata ) (Table 1).
