Description. General appearance as in Paralaevicephalus grossus sp. nov..

Male genitalia: Subgenital plate short, outer and apical margins rounded, macrosetae irregularly arranged towards apex; elongate stout process arising basally from inner margin, strongly curved dorsad at apex ( Fig.

38). Style short, apical process narrow, rounded, not exceeding apical margin of subgenital plate, base narrow ( Fig. 38 ). Connective with arms forked, without stem ( Fig. 41 ). Aedeagus with shaft short, curved dorsad, apex lamellar. ( Figs. 39, 40 ).

Measurement. Length (including tegmen): 3, 2.7–2.9 mm; Ƥ, 2.9–3.1 mm.

Etymology. The species name is derived from the Latin words lamellatus , indicating the end of aedeagus is lamellar.
