2. Kapsa (Rigida) aculeiformis Cao & Zhang sp. nov.

(Figs 1a–d, 6)

Description. Body (Fig. 1a, b) yellow-whitish. Coronal suture (Fig. 1c) visible basally, not exceeding midlength of vertex. Face (Fig. 1d) relatively short.

Abdominal apodemes short, extended to anterior margin of 4th sternite. Anal tube appendage (Fig. 6 a, b) broadened subbasally and narrowed apically.

Pygofer dorsal appendage (Fig. 6 a, b) short, tapering apically, slightly curved ventrad, with some furrows on ventral side. Subgenital plate (Fig. 6 a, d) with 4 lateral macrosetae, stout microsetae of basal group smaller towards apex. Paramere (Fig. 6 e) distinctive, apex forked, apical branch shorter than the basal one. Connective (Fig. 6 f) narrow, lateral arms long, manubrium short. Aedeagal shaft (Fig. 6 g, h) compressed, denticulate dorsoapically, with small thornlike process terminally on ventral side; preatrium large, without process; gonopore terminal.

Measurement. Body length: males 3.0– 3.10mm, females 3.1mm.

Material examined. Holotype: 3, China: Tibet, Linzhi, Gengzhang, 3050m, 1 vi 1978, coll. Li Fasheng. Paratypes: 1Ƥ, same data as holotype; 131Ƥ, China: Tibet, Linzhi, 3050m, 7 vi 1978, coll. Li Fasheng; 33, China: Tibet, Linzhi, Mafenggou, 3050m, 3 vi 1978, coll. Li Fasheng.

Remarks. This species resembles K. alba Dworakowska, but can be distinguished by its longer anal tube appendage, forklike paramere apex, and thorn-shaped apical process of the aedeagal shaft. Etymology. The specific name is derived from the Latin word “ aculeiformis ”, referring to the shape of the apical process of the aedeagal shaft.

3. Kapsa (Rigida) apicispina Yang & Zhang sp. nov. (Figs 1 e–h, 7)

Description. Body (Fig. 1 e, f) yellow-whitish. Coronal suture (Fig. 1 g) visible in basal half. Face (Fig. 1 h) long. Abdominal apodemes small, extended to anterior margin of 4th sternite. Anal tube appendage rudimentary, small, apex not hooked.

Pygofer dorsal appendage (Fig. 7 a) robust, base broad and nearly straight, tapering to slightly ventrally curved apex. Subgenital plate (Fig. 7 a, c) with 4 lateral macrosetae. Paramere (Fig. 7 d, e) slender, apex foot-shaped, preapical lobe small. Connective (Fig. 7 f) with lateral arms long, manubrium short. Aedeagal shaft (Fig. 7 g, h) compressed, curved caudad, with a long lamellate spine at mid-ventral margin of apex; preatrium short tapering basally; dorsal apodeme small; gonopore apical.

Measurement. Body length: males 3.0mm, females 3.0mm.

Material examined. Holotype: 3, China: Yunnan Prov., Mengyuan, 1000m, 18 xii 1999, coll. I. Dworakowska. Paratypes: 5313Ƥ, same date as holotype; 13, China: Yunnan Prov., MengYuan, Sancha River, 840m, 19 xii 1999, coll. Qin Daozheng.

Remarks. The new species is similar to K. bela Dworakowska, but can be distinguished by the very distinctive shape of the aedeagus.

Etymology. The specific name is derived from the Latin prefix “apic-” and Latin word “spineus”, referring to the long spine at the apex of the aedeagal shaft.
