Changa Lee, 2016: 596–597 [type species: Cosmopsaltria sita Distant, 1881 (southern

India)].

Diagnosis

Body medium-sized (body length around 24 mm), but smaller than other Haphsa -like genera. Head including compound eyes wider than mesonotum. Postclypeus moderately prominent, without symmetrical series of fuscous fasciae along transverse grooves but with marks forming the shape of the letter X in general. Pronotum longer than head and distinctly shorter than mesonotum excluding cruciform elevation. Lateral pronotal collar dentate. Mesonotum greenish or ochraceous with black marks. Wings hyaline, with eight and six apical cells on fore wing and hind wing, respectively. Fore wing with apical cells in comparatively long. Fore wing with infuscations on radial and radiomedial crossveins. Male operculum longer than wide, about 1.5 times to twice as long as wide, reaching about middle of abdominal sternite IV. Male opercula separated. Male abdomen much longer than head and thorax together. Male abdominal tergite 3 slightly wider than mesonotum. Timbal cover about as long as wide, mostly concealing timbal but exposing some portion of inner and anterior parts of timbal in dorsal view. Male pygofer obovate in ventral view. Clasper and upper lobes of pygofer absent. Uncus thick and short, with uncal lobes fused at base, bifurcate and widely separated from each other distally in ventral view; distally hooked inwardly in lateral view. Basal lobe of pygofer absent. Aedeagus thin, protruding between bases of uncal lobes.

Species included

Changa sita (Distant, 1881) comb. rev. and Changa jsguillotsi (Boulard, 2005) comb. rev.

Remarks

This genus is distinguished from Haphsa by the small body size, more slender body (ratio of body length to head width about 3.20), long male abdomen, black to fuscous marks on the postclypeus, forming the shape of the letter X, long fore wing apical cells, small timbal cover and the shape of uncal lobes which are widely separated from each other at apices and are hooked inwardly.
