Diagnosis

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

(1) the elongate frons (at least 1.2 times as long in midline as wide) with median carina extending from dorsal margin almost to frontoclypeal suture and without a black tubercle in the middle of the disc;

(2) the tegmina distinctly widest in the basal ⅓, not subparallel nor regularly rounded;

(3) the vertex with anterior margin in dorsal view only very slightly angularly convex or straight;

(4) the anal tube of male dorsoventrally flattened and wide at midlength;

(5) the aedeagus rather simple, with a single pair of ventral processes curved anterodorsad.

Note

Two species of Pusulissus are currently known from Vietnam: P. phiaoacensis Bourgoin & Wang, 2020 from Cao Bang Province and P. quangninhensis Constant & Pham, 2024 from Quang Ninh Province. An additional record of the genus, from Vinh Phuc Province, was provided, based on an incomplete female specimen ( Bourgoin & Wang 2020; Constant & Pham 2024).
