Genus Rostrolatum Che, Zhang & Wang, 2020

Rostrolatum Che, Zhang & Wang, 2020 in Zhang et al. 2020: 335.

Type species: Rostrolatum separatum Che, Zhang & Wang, 2020 , by original designation.

Diagnosis

The genus Rostrolatum can be differentiated from all other genera of Parahiraciina by the following combination of characters:

(1) the head elongate with a more or less conical cephalic process curved anteroventrally;

(2) the vertex with lateral margins concave and with incomplete median carina;

(3) the tegmina evenly rounded along lateral margin in dorsal view;

(4) the anal tube of male dorsoventrally flattened and with apical margin roundly emarginate;

(5) the aedeagus rather simple, moderately curved in lateral view and with a single pair of ventral processes curved anterodorsad.

Note

The genus was recently described in Zhang et al. (2020) to include a new species from Hainan Island, and it is here recorded from Vietnam for the first time.

Species included

Rostrolatum curviceps sp. nov.
