2. Kapsa (Rigida) aculeiformis Cao & Zhang View in CoL sp. nov.
( Figs 1a–d View FIGURE 1. a – d , 6 View FIGURE 6 )
Description. Body ( Fig. 1a, b View FIGURE 1. a – d ) yellow-whitish. Coronal suture ( Fig. 1c View FIGURE 1. a – d ) visible basally, not exceeding midlength of vertex. Face ( Fig. 1d View FIGURE 1. a – d ) relatively short.
Abdominal apodemes short, extended to anterior margin of 4th sternite. Anal tube appendage ( Fig. 6 View FIGURE 6 a, b) broadened subbasally and narrowed apically.
Pygofer dorsal appendage ( Fig. 6 View FIGURE 6 a, b) short, tapering apically, slightly curved ventrad, with some furrows on ventral side. Subgenital plate ( Fig. 6 View FIGURE 6 a, d) with 4 lateral macrosetae, stout microsetae of basal group smaller towards apex. Paramere ( Fig. 6 View FIGURE 6 e) distinctive, apex forked, apical branch shorter than the basal one. Connective ( Fig. 6 View FIGURE 6 f) narrow, lateral arms long, manubrium short. Aedeagal shaft ( Fig. 6 View FIGURE 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 View FIGURE 1. a – d e–h, 7)
Description. Body ( Fig. 1 View FIGURE 1. a – d e, f) yellow-whitish. Coronal suture ( Fig. 1 View FIGURE 1. a – d g) visible in basal half. Face ( Fig. 1 View FIGURE 1. a – d 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 View FIGURE 7 a) robust, base broad and nearly straight, tapering to slightly ventrally curved apex. Subgenital plate ( Fig. 7 View FIGURE 7 a, c) with 4 lateral macrosetae. Paramere ( Fig. 7 View FIGURE 7 d, e) slender, apex foot-shaped, preapical lobe small. Connective ( Fig. 7 View FIGURE 7 f) with lateral arms long, manubrium short. Aedeagal shaft ( Fig. 7 View FIGURE 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.
