Allacta Saussure & Zehntner, 1895

Diagnosis.

The characteristics of the external structure and male genitalia were given in full in Roth (1993b) and He et al. (2019). The following are supplements or adjustments. Tegmina and wings usually fully developed, sometimes reduced ( A. bifolium Li & Wang, sp. nov. and A. redacta Li & Wang, sp. nov.). Subgenital plate usually with two styli, a few with one stylus ( A. unicaudata Li & Wang, sp. nov.).

Remarks.

Species of Allacta from China were listed by He et al. (2019); three belong to the hamifera species group ( A. alba , A. bimaculata and A. bruna ) and the remaining four belong to the polygrapha species group ( A. ornata , A. robusta , A. transversa and A. xizangensis ) ( Roth 1993b; Wang et al. 2014; He et al. 2019). The five new species are placed in the hamifera species group by the male interstylar margin being broadly V-shaped ( Roth 1993b).
