Kutara trispinosa Xu & Zhang  sp. nov.

( Figs 1–3View FIGURE 1View FIGURE 2View FIGURE 3)

Description: Body length (including tegmina), male: 8.0mm, female: 8.2mm.

Head and thorax orange; crown ( Fig. 1A,B,DView FIGURE 1) with a transverse medial band, dark brown; clypeus and clypellus ( Fig. 1CView FIGURE 1) sordid brown. Pronotum ( Fig. 1A,BView FIGURE 1) marked with dark brown, posteriorly. Scutellum ( Fig. 1A,BView FIGURE 1) with basal triangles and medial area sordid brown. Forewings ( Fig. 1A,BView FIGURE 1) brownish hyaline with apical margin and veins darker brown. Male abdomen ( Fig. 1FView FIGURE 1) yellowish.

External features as in generic description.

Male pygofer side ( Fig. 2IView FIGURE 2) caudally narrowly rounded. Subgenital plate ( Fig. 2J,KView FIGURE 2) elongate; wide basally, tapering distally with several short and fine hair-like microsetae arising from lateral margin, irregularly arranged. Style ( Fig. 2J,KView FIGURE 2) with lateral lobe indistinct; apical process very short. Connective ( Fig. 2J,LView FIGURE 2) with stem similar in length to arms, strongly widening distally, ventral margin angled at mid-length in lateral view. Aedeagus ( Fig. 2IView FIGURE 2,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. 3PView FIGURE 3) with bowl-shaped notch and lateral margin pointed. The first valvulae ( Fig. 3Q,RView FIGURE 3) with sculpturing pattern strigate dorsally; the second valvulae ( Fig. 3S, TView FIGURE 3) with a dorsal toothlike process, dorsal margin with serrate teeth about apical 1/3; the third valvulae ( Fig. 3UView FIGURE 3) 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)GoogleMaps  . 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)GoogleMaps  .

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.
