( Figs 1–3 ) Description: Body length (including tegmina), male: 8.0mm, female: 8.2mm . Head and thorax orange; crown ( Fig. 1A,B,D ) with a transverse medial band, dark brown; clypeus and clypellus ( Fig. 1C ) sordid brown. Pronotum ( Fig. 1A,B ) marked with dark brown, posteriorly. Scutellum ( Fig. 1A,B ) with basal triangles and medial area sordid brown. Forewings ( Fig. 1A,B ) brownish hyaline with apical margin and veins darker brown. Male abdomen ( Fig. 1F ) yellowish. External features as in generic description. Male pygofer side ( Fig. 2I ) caudally narrowly rounded. Subgenital plate ( Fig. 2J,K ) elongate; wide basally, tapering distally with several short and fine hair-like microsetae arising from lateral margin, irregularly arranged. Style ( Fig. 2J,K ) with lateral lobe indistinct; apical process very short. Connective ( Fig. 2J,L ) with stem similar in length to arms, strongly widening distally, ventral margin angled at mid-length in lateral view. Aedeagus ( Fig. 2I ,M-O) with shaft elongate, cylindrical, curved dorsad and tapering distally, with a long spine-like dorsal extension beyond gonopore and a pair of moderately long spine-like subapical processes arising from ventral margin, not surpassing apex of shaft; gonopore subapical on dorsal side. Female : Hind margin of seventh sternite ( Fig. 3P ) with bowl-shaped notch and lateral margin pointed. The first valvulae ( Fig. 3Q,R ) with sculpturing pattern strigate dorsally; the second valvulae ( Fig. 3S, T ) with a dorsal toothlike process, dorsal margin with serrate teeth about apical 1/3; the third valvulae ( Fig. 3U ) with several longish setae on ventrolateral surface.

The new species epithet derives from the Latin word trispinosa , referring to the spine-like extension of the aedeagal shaft beyond the gonopore and paired spine-like processes subapically. Remarks . This new species can be distinguished from all other species of the genus by the following characters: head and pronotum orange; style with apical apophysis very short; shaft with a pair of ventral spine-like processes subapically, not exceeding spine-like apex of shaft.
