Description
Eutetrapha stigmosa Pu & Jin, 1991
Figs. 22–26
Eutetrapha stigmosa Pu & Jin, 1991: 191, 196. Type locality: China, Guangxi, Tianpingshan. Type depository: IZAS. Eutetrapha stigmosa; Hua et al., 2009: 455 (part); Löbl & Smetana, 2010: 324 (part); Lin, 2015: 278, fig. 217695.
Supplementary description (female and male genitalia). Female (Fig. 23, described for first time) matches male quite well except sexual differences of genus, including claws simple, antennae shorter than male and subequal to body length, body stouter and middle of last visible abdominal ventrite with a fine longitudinal furrow. Female genitalia not available. Male genitalia (Figs. 24–26): Tergite VIII (Fig. 24) nearly as broad as long, apex weakly projected, with setae which are long at sides, and shorter and sparser at middle. Spiculum gastrale slightly shorter than ringed part of tegmen, spiculum relictum about one half of spiculum gastrale in length. Tegmen (Figs. 25 a–c, 26) about 3.5 mm in length; lateral lobes slender, each about 0.8 mm long and 0.2 mm wide; apex with fine setae which are shorter than half of lateral lobes; median lobe slightly curved (Fig. 25 b), slightly shorter than tegmen (35:37); median struts about half-length of median lobe (Fig. 25 c); apex of ventral plate (Fig. 26) pointed; endophallus more than triple length of median lobe, with more than four pieces of basal plate-like sclerites (located behind apex of median struts), two bands of supporting armature, and largely and quite strongly chitinized part after basal plate-like sclerites. Rod-like sclerites at end destroyed in specimen observed, but it is assumed that there are three of similar length.
Diagnosis. This species can be easily separated from the known congeners by the grayish-white pubescent spots located along the humeral carina of elytra and arranged in a longitudinal row (Pu & Jin 1991).
Distribution. China: Guangxi, Guizhou (new province record).
Type specimens examined. Holotype (Fig. 22), male, Guangxi, Tianpingshan, 1963. VI.6, leg. Qi-Jing You (IZAS, IOZ (E)217695).
Other specimens examined. Guizhou: 1 female (Fig. 23), Jiangkou, Fanjingshan, 2001. VII.29, leg. Guo- Dong Ren (HBU).
Remarks. The allotype and one male paratype from Hubei Province were misidentifications of Eutetrapha parastigmosa Lin & Yang, sp. nov. The known localities of this species are Guangxi and Guizhou, which suggests a relationship with the Nanling Mountains. One specimen was reported from Guizhou, Fanjingshan by Wang (2014: 722, fig. 3419+1) as a variety of E. elegans, which obviously belonged to this species, and the locality was confirmed by the specimen we examined.
