Palp. With dense dark and long setae on dorsal of patella, tibia and pro-dorsal side of proximal of cymbium, cymbium flattened. Embolus curved and stout, compound terminal apophysis (CTA) flattened and closed to distal part of embolus. Retrolateral tibial apophysis (RTA) base broad, bifurcated distally. Tegular lobe (TL) well developed, pointing downwards, with stout ending (Fig. 2 F, G, Fig. 3 C and D).

Epigyne (Fig. 3 A – B and E – F) 1.5 times longer than wide, with pair of hoods near epigastral furrow; atria oval, with distinct anterior rim (ar) and ridge of the septum (rs); copulatory openings locating in anterior portion of atria; spermathecae thick V-shaped, with slightly twisted inner tubes; fertilization ducts well-developed and close to proximal position of spermathecae.

Diagnosis

The new species is similar to Nigorella hirticeps ( Song & Chai, 1992) in the genital morphology, but it can be distinguished from the latter by the following: (1) the dorsal surface of abdomen in males with scutum (Fig. 2 A, vs. in N. hirticeps , such scutum is absent; see Lin et al. (2023): fig. 12 A); (2) the embolus is upturned distally (Fig. 2 F and 3 C; vs. in N. hirticeps , the embolus extends gently towards the distal end); (3) the compound terminal apophysis of the embolus (CTA) turns smoothly to the retrolateral side, forming no ledge-like extension visible from the ventral view (Fig. 2 F and 3 C; in N. hirticeps , the CTA forms a small, ventrally visible ledge-like extension; see Lin et al. (2023): fig. 11 A); (4) the female atria have obvious anterior rims (ar; Fig. 2 A and E; vs. in N. hirticeps , such rims are absent; see Zha and Zhang (2014): fig. 9); (5) the spermathecae have lateral extensions distally (Fig. 3 B and F; vs. such extensions are absent in N. hirticeps ; see Zha and Zhang (2014): fig. 10).

Etymology

The specific epithet is derived from the type locality and is a noun in apposition.

Distribution

Type locality in Guangxi, China (Fig. 1 ).
