9. Kapsa (Rigida) serrata Cao & Zhang sp. nov.

( Figs 2 m–p, 13)

Description. Body ( Fig. 2 m, n) yellow-whitish. Coronal suture ( Fig. 2 o) obvious, exceeding midlength of vertex. Face ( Fig. 2 p) short.

Abdominal apodemes ( Fig. 13 a) short, extend to the 4th sternite. Anal tube appendage ( Fig. 13 b, c) with apical half slim.

Pygofer dorsal appendage ( Fig. 13 b, c) straight, knife-shaped. Subgenital plate ( Fig. 13 b, d) with 4 macrosetae, with numerous stout microsetae subbasally. Paramere ( Fig. 13 e) bifurcated apically, ventral branch shorter than dorsal branch. Connective ( Fig. 13 f) with lateral arms long, manubrium short. Aedeagal shaft ( Fig. 13 g, h) relatively broad, denticulate dorsoapically, with serrated, compressed protrusion ventrally; dorsal apodeme well developed, preatrium short; gonopore apical, ventral.

Measurement. Body length: male 3.2mm.

Material examined. Holotype: 3, China: Tibet, Yigong, 2300m, 16 vi 1978, coll. Li Fasheng.

Remarks. This species resembles K. maculata Sohi & Mann , but the pygofer dorsal appendage is broad and straight, the anal tube appendage is curved caudad, the apex of the paramere is bifurcated, the aedeagal shaft is more slender with a serrated, compressed ventral protrusion, and lacks a ventral process.

Etymology. The specific name is derived from the Latin word “serratus”, referring to serrated edge of aedeagal ventral protrusion.
