Mintonia shiwandashan Wang, Mi, Li & Xu, 2024, sp. nov.

Mintonia shiwandashan sp. nov. Figs 11, 47 Type material. Holotype ♂ (TRU - JS 0743), China: • Guangxi Zhuang Autonomous Region, Fangchenggang City, Shiwandashan National Nature Reverse, Wanglue Station (21°54.23'N, 107°54.18'E, ca 310 m), 30. IV. 2021, A. L. He et al. leg. Etymology. The specific name refers to the type locality: Shiwandashan National Nature Reverse; noun in apposition. Diagnosis. Mintonia shiwandashan sp. nov. resembles M. breviramis Wanless, 1984 in having very short embolus (E), but can be easily distinguished by the presence of baso-retrolateral and dorsal tibial apophyses, and by the bifurcated retrolateral tibial apophysis (RTA) (Fig. 11 B, C) vs lacking baso-retrolateral and dorsal tibial apophyses and having non-bifurcated retrolateral tibial apophysis (Wanless 1984: fig. 12 A, B). Description. Male (Fig. 11). Total length 5.10. Carapace 2.43 long, 2.05 wide. Abdomen 2.62 long, 1.71 wide. Eye sizes and interdistances: AME 0.62, ALE 0.38, PLE 0.34, AERW 2.00, PERW 1.86, EFL 1.19. Legs: I 5.92 (1.70, 0.88, 1.53, 1.18, 0.63), II 5.43 (1.60, 0.85, 1.30, 1.10, 0.58), III 5.08 (1.50, 0.50, 1.25, 1.25, 0.58), IV 6.86 (1.95, 0.78, 1.68, 1.75, 0.70). Carapace pale yellow except eye field dark, with elevated and square cephalon, covered with brown and golden thin setae; fovea dark. Chelicerae yellow, with three promarginal and seven smaller retromarginal teeth. Legs yellow, tinged with brown, spiny. Dorsum of abdomen pale to brown, covered with golden and dark setae, with two well-visible pairs of anteromedian muscle depressions; venter pale, with two pairs of dotted lines medially. Palp (Fig. 11 A – C): femur length / width ratio ca 3.3; patella ~ 1.5 × longer than wide in retrolateral view; tibia slightly longer than wide in ventral view, with almost half-round, lamellar base-retrolateral apophysis (BTA); ventral tibial apophysis (VTA) almost sub-triangular; retrolateral tibial apophysis (RTA) strongly sclerotized, bifurcated with two blunt rami; dorsal tibial apophysis (DTA) bar-shaped, with blunt end in dorsal view; cymbium ~ 1.47 × longer than wide in ventral view; tegulum oval; embolus (E) strongly sclerotized, broad, with tapered projection. Female. Unknown. Distribution. Known only from the type locality in Guangxi, China (Fig. 47). Comments. Although the new species is similar to Portia jianfeng Song & Zhu, 1998 in palpal structure, it has not been considered to be a member of Portia Karsch, 1878 because it lacks tufts on the abdomen and a pronounced dorso-basal flange on the cymbium, which are diagnostic for Portia (Wanless 1984). The new species is provisionally placed in the genus Mintonia due to the general similarity of palpal structure to current congeners.
