Gymnaetoides polaoensis View in CoL sp. nov.
( Figs. 1 View FIGURE 1 , 2 View FIGURE 2 )
Description. Male. Body medium-sized ( Figs. 1 View FIGURE 1 A–C). Vertex of head divided into two conical tubercles, bases of the well-developed tubercles drawn together, obtusely rounded apices separated ( Figs. 1D, E View FIGURE 1 ). Size of eyes not distinctly reduced ( Figs. 1D, E View FIGURE 1 ). Anterior margin of pronotum straight, posterior margin protruding caudad, ventral margin arc-shaped ( Fig. 1F View FIGURE 1 ); posterior margin of mesonotum protruding caudad; posterior margin of metanotum slightly protruding caudad.
Legs long and slender. Coxae with small medial projections. Fore femur about 1.8 times longer than the pronotum, ventrally unarmed, internal genicular lobe with 1 small spine, external genicular lobe with 1 long spine; fore tibia ventrally with 1 inner spine and 2 outer spines, apex with 1 small outer spine on dorsal surface and 1 pair of long spines on ventral surface, between the paired ventral spines with 1 small spine. Middle femur ventrally unarmed, internal and external genicular lobes with 1 long spine respectively; middle tibiae ventrally with 1 inner spine and 1 outer spine, apex with 1 pair of dorsal spines and 1 pair of ventral spines, between the paired ventral spine with 1 small spine. Hind femur ventrally unarmed, apex with 1 small dorsal spine; hind tibia dorsally with 78–81 inner spines and 74–79 outer spines, arrange in groups, ventral and dorsal surface with 1 pair of small subapical spines respectively, apex with 1 pair of long dorsal spines and 1 pair of long ventral spines; the longest dorso-apical spine not exceeding the dorso-apical spine of hind metatarsus ( Fig. 1G View FIGURE 1 ). Hind metatarsus with bristles beneath.
Abdominal sternites with short ventral projections ( Fig. 1H View FIGURE 1 ). Paraproct and epiproct normally developed, epiproct nearly triangular ( Fig. 1I View FIGURE 1 ). Epiphallus of male genitalia like the shape of “H” ( Fig. 2A View FIGURE 2 ); lateral lobes of genitalia distinctly sclerotized, dorsal lateral lobes shorter than ventral lateral lobes ( Figs. 2A, B View FIGURE 2 ).
Female. Unknown.
Coloration. Body brown with dark brown or black irregular stripes on tergites and abdominal sternites ( Figs. 1 View FIGURE 1 A–C). Face without distinct longitudinal bands ( Fig. 1D View FIGURE 1 ). Eyes off-white ( Figs. 1D, E View FIGURE 1 ). Legs light brown ( Figs. 1 View FIGURE 1 A–C).
Material examined. Holotype: 1♂, Polao Cave, Zhenfeng County, Southwest Guizhou Autonomous Prefecture , Guizhou Province, 24.VIII.2020, coll. Shihui Huang & Changqing Luo. Paratype: 1♂, same data as the holotype.
Measurements (mm). Body: ♂13.93–14.39; pronotum: ♂5.72–6.52; fore femur: ♂10.72–11.02; hind femur: ♂19.94–22.37.
Distribution. China (Guizhou).
Discussion. Gymnaetoides contained only three species before this study. This new species can be easily distinguished from the other Gymnaetoides by the morphological features of male genitalia (e.g. the shape of epiphallus and lateral lobes), body size, coloration and the number of spines on the hind tibiae. It should be noted that the size of the eyes of males is not obviously reduced, but the coloration of the eyes is off-white, which suggests that the pigments in the eyes are somewhat reduced.
Etymology. The specific epithet refers to the Polao Cave where this species occurs.
