Note.

See the note under D. laticeps comb. nov. This species was originally described in the genus Acesines Stål, but similar to members of Dunnius in external morphology and male genitalia like the shape of paramere, genital capsule (shape of caudolateral lobes, ventral and dorsal rim) and shape of phallus similar to that of D. barpetensis sp. nov. The absence of metasternal notch and the short basal abdominal tubercle, which is not in contact with metasternum (see under the note of D. laticeps), which is evident from the description and ventral habitus image of this species by Fan (2011: 573, fig. 219). This also indicates that Acesines tridentatus is congeneric with Dunnius and hence transferred from Acesines to Dunnius in this paper.
