Type
species
Parasogata binaria
Zhou, Yang & Chen, 2018
(by original designation).
Amended diagnosis
Yellowish white to brown (
Fig. 1A
). Vertex, pronotum and mesonotum with uninterrupted white fascia. Vertex, frons, face, antennae yellowish brown to yellowish white. Pronotum and mesonotum yellowish white (
Fig. 1
C–D). Forewings and hindwings hyaline with prominent veins (
Fig. 1B
). Legs yellowish white. Abdomen yellowish orange (
Fig. 1B
). Head including eyes narrower than pronotum (
Fig. 1C
). Vertex subquadrangular, weakly anteriorly projected; anterior margin arched, submedian carinae uniting at apex; Y-shaped carina feeble (
Fig. 1C
). Frons with lateral margins weakly diverging ventrad (widest near frontoclypeal suture); much longer in middle line than wide at widest part; median carina forked at fastigium (
Fig. 1D
). Antennae cylindrical, scape longer than wide, pedicle more than twice length of scape (
Zhou
et al.
2018
: figs 13–16). Pronotum relatively broad, lateral carinae nearly attaining hind margin (
Fig. 1C
). Spinal formula of hind leg 5-7-4. Post-tibial spur with 29–32 fine teeth along hind margin. Pygofer in profile wider ventrally than dorsally, lateral quadrangular areas strongly sclerotized, medioventral process absent. Diaphragm well developed, dorsal margin broadly convex, armature very weak (
Fig. 2
D–F). Aedeagus long, tubular, weakly upturned, with row of dorsal subapical processes (
Fig. 2
B–C;
Zhou
et al.
2018
: figs 26, 52). Parameres (= gonostyli) simple (basal and apical angles not developed), widely divergent apically (
Fig. 2H
;
Zhou
et al.
2018
: figs 27–28, 53–54). Suspensorium elongate (
Zhou
et al.
2018
: figs 29, 55). Segment 10 collar-shaped, lateroapical angles produced into 1–2 paired processes (widely separated at base in caudal view) (
Fig. 2G
;
Zhou
et al.
2018
: figs 24–25, 51).
Remarks
This genus is readily recognized by its large size and vertex, pronotum and mesonotum bearing an uninterrupted white fascia. The genus was compared with four similar genera by
Zhou
et al.
(2018)
and considered most similar to
Sogata
Distant, 1906
but distinguished by the phallus being up-curved, bearing a dorsal row of subapical processes.
