Type species: Chinaia bella Bruner & Metcalf, 1934  by original designation.

Total length. 5.2– 10 mm.

Diagnosis. Head with anterior margin broadly rounded, without transverse carina in transition between crown and frons ( Figs 1, 3View FIGURES 1 – 11, 12, 13View FIGURES 12 – 21, 22View FIGURES 22 – 30, 31, 33View FIGURES 31 – 40); ocelli located slightly below transition margin between crown and frons ( Figs 23View FIGURES 22 – 30, 13View FIGURES 12 – 21, 23View FIGURES 22 – 30, 32–33View FIGURES 31 – 40); clypeus with lateral margins apically divergent ( Figs 2View FIGURES 1 – 11, 23View FIGURES 22 – 30, 32View FIGURES 31 – 40). Pronotum with posterior margin straight, not emarginated ( Figs 1View FIGURES 1 – 11, 12View FIGURES 12 – 21, 22View FIGURES 22 – 30, 31View FIGURES 31 – 40); forewing thickened, opaque and colored on basal and middle thirds, always with contrasting stains in yellow, orange, red and/or brown tones, only apical third hyaline ( Figs 4View FIGURES 1 – 11, 14View FIGURES 12 – 21, 24View FIGURES 22 – 30, 34View FIGURES 31 – 40); forewing venation obscure except claval suture and apical cells, with three apical cells ( Figs 4View FIGURES 1 – 11, 14View FIGURES 12 – 21, 24View FIGURES 22 – 30, 34View FIGURES 31 – 40); hind wing with R4+5 and M1+2 divergent apically, not fused. Male genitalia: pygofer either with dorsal processes or elongated apex ( Figs 5View FIGURES 1 – 11, 15View FIGURES 12 – 21, 25View FIGURES 22 – 30, 35View FIGURES 31 – 40); subgenital valve fused with subgenital plates, but with weak depigmented line between them; subgenital plates deep and scoop-shaped, fused only on basal third, sometimes with six or less setae close to inner margins ( Figs 6View FIGURES 1 – 11, 16View FIGURES 12 – 21, 26View FIGURES 22 – 30, 36View FIGURES 31 – 40); styles with preapical lobe well developed and laterally projected ( Figs 7–8View FIGURES 1 – 11, 17–18View FIGURES 12 – 21, 27–28View FIGURES 22 – 30, 37–38View FIGURES 31 – 40); connective cruciform, articulated to aedeagus ( Figs 8View FIGURES 1 – 11, 18View FIGURES 12 – 21, 28View FIGURES 22 – 30, 38View FIGURES 31 – 40); aedeagus moderately straight or recurved, with or without lateral flaps or processes, and with apical gonopore ( Figs 9–11View FIGURES 1 – 11, 19–21View FIGURES 12 – 21, 29–30View FIGURES 22 – 30, 39–40View FIGURES 31 – 40); anal tube simple and membranous, without processes ( Figs 5View FIGURES 1 – 11, 15View FIGURES 12 – 21, 35View FIGURES 31 – 40).

Notes. Chinaia  can be easily separated from the other genera of Neocoelidiinae  by the general coloration of the crown, pronotum and mesonotum, yellow to orange with dark-orange to red stains and/or strips ( Figs 41–47View FIGURES 41 – 47). The forewings are thickened and colored on the basal and middle thirds, always with contrasting stains in yellow, orange, red and/or brown tones, apical third hyaline ( Figs 41–47View FIGURES 41 – 47). Besides the characters given above, the following combination of features also help to separate Chinaia  from the other genera: (1) pygofer, in lateral view, approximately triangular, enlarged basally, narrowing gradually towards apex ( Figs 5View FIGURES 1 – 11, 15View FIGURES 12 – 21, 25View FIGURES 22 – 30, 35View FIGURES 31 – 40); (2) valve fused to subgenital plates, with depigmented line between them ( Figs 6View FIGURES 1 – 11, 16View FIGURES 12 – 21, 26View FIGURES 22 – 30, 36View FIGURES 31 – 40); and (3) connective cruciform ( Figs 8View FIGURES 1 – 11, 18View FIGURES 12 – 21, 28View FIGURES 22 – 30, 38View FIGURES 31 – 40).
