4. Kabakra acutata sp. nov.

( Figs 7–11 , 46–59 )

Description. The only specimen has lost its natural coloration and shape after removal from alcohol and drying. Ground color of anterior dorsum ochre-testaceous. Coronal suture only visible in basal half, pair of tadpole-shaped patches brownish except its ochre center, small patch at tip orange ( Figs 7, 9 ); face with its upper 1/5 sordid yellowwhitish, frontoclypeus light brown on upper part and being much darker towards lower part, gena, lorum and anteclypeus blackish brown ( Fig. 10 ). Pronotum with stripes and patches on antero-lateral part dark brown, which have divided ochre-testaceous tint into 8 patches; oval patch in center and two semicircular patches along hind margin grey, remaining part light brownish ( Figs 7, 9 ). Basal triangles large, extending to scutellum, blackishbrown; transverse patch on top of scutoscutellar sulcus and stripe along midline of mesonotum brownish, tip of scutellum blackish-brown ( Figs 7, 9 ). Forewing infuscated, veins lighter, sides of brochosome field ochre-yellow, patches as in Fig. 11 greyish-brown ( Fig. 11 ); hind wing smoky, veins light brownish.

Basal abdominal apodemes comparatively long, slightly exceeding fourth sternite ( Figs 46 ).

Pygofer side with dorso-caudal margin and ventro-caudal margin membranous, with about four macrosetae at dorsal margin and several rigid microsetae on dorso-caudal membrane, terminal part pointed and directed mesad; pygofer dorsal appendage cheliform ( Figs 47–50 ). Subgenital plate resembling that of K. fuscata , rounded apically, central part of dorsal fold well pigmented, macrosetae more basad than in type species ( Fig. 52 ). Style with basal and apical part long, central part short, apical part slender and tapering towards apex ( Fig. 53 ). Connective as in K. pompela , two arms thick, separated with ventral sclerite caudad and fused with latter at central lobe ( Figs 54–56 ). Aedeagal shaft tubular, with pair of short, slim processes subapically on dorsum, preatrial processes almost as long as aedeagal shaft, provided with minute oval depressions at terminal half; gonopore subapical, ventral ( Figs 57–59 ).

Measurement. Male length 2.3 mm.

Material examined. 1 Holotype: 3, CHINA, Yunnan Prov., Jinghong, Yexianggu, 30-viii-2010, coll. Zhang Meng.

Deposition. Entomological Museum of NWAFU.

Diagnosis. Distinguished from other Kabakra by the pointed terminal part of pygofer side, cheliform pygofer dorsal appendage and existence of aedeagal preatrial processes.

Etymology. This new specific epithet is derived from the Latin word “acutatus” in view of the pointed caudal part of the pygofer side.
