Diagnosis
Body pale brown to blackish brown, mostly yellowish brown. Clypeus normal, not thickened. Pronotum usually oval, wider than length. Tegmina and wings usually fully developed, a few slightly reduced (T.hainanensis). Tegmina with M, CuA oblique, hind wings with R straight, sometimes forked, M and CuA usually straight or nearly so, latter with 1–6 (usually 4 or 5) complete branches; apical triangle small, reduced or absent. Anteroventral margin of front femur Type B2 or B3; pulvilli present only on the fourth tarsomere of all legs, tarsal claws symmetrical and unspecialized, arolia present. Male abdominal terga unspecialized. Male genitalia usually have three principal phallomere sclerites, the hook-like phallomere on right side, the median, and the left; most species have an accessory median phallomere. Ootheca not rotated prior to deposition.
Note
Roth (1996)[4] and Wang et al. (2014)[5] discussed the difference among Allacta, Sundablatta, and Pseudophyllodromia, but actually, Allacta is closely related with the three genera Margattea, Balta, and Sorineuchora according to Wang et al. (2017)[7], which are also under the subfamily Pseudophyllodromiinae. The most striking difference between Allacta and its closely related genera is pulvilli only present on the fourth tarsomere of all legs; or anteroventral margin of front femur Type B2 or B3. It is possible that Allacta and Balta prove to be synonym in the future by molecular method.
Remarks
Roth (1993)[2] erected three species groups under Allacta based on color patterns and male interstylar margin, viz. funebris species group, hamifera species group, and polygrapha species group. According to Roth (1993)[2], these three species can be put in the hamifera species group, A.bruna sp. n. by having a dark pronotum and keel-like ridge at interstylar margin (Figs 4, 11) and A.alba sp. n. and A.hainanensis (Liu et al. 2017) comb. n. by the two close lobes between the styli (Figs 23, 34).
