Kutara trispinosa Xu & Zhang sp. nov.

(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.

Material examined. Holotype ♂, Vietnam, Province Ninh Binh Cuc Phuong, PL, route forêt, 20°16′46″N, 105°40′43″E, 221m, 18-IX-2015, A. Soulier-Perkins (MNHN). Paratypes: 3♀, Vietnam, Vinh Phuc, Tam Dao, sweeping understory in 2º pine forest, 21.4509ºN, 105.6325ºE, 741m, 13-VII-2019, C.H. Dietrich, VN19-8-2 (INHS).

Etymology. 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.
