Type material.

Holotype ♂: China, Yunnan Province: Tengchong County, Dahaoping Village, km 41-46 on the road from Bawan to Tengchong, 24.5563°N, 99.4516°E, 2416 m, 18.X.2003, Guo Tang leg. (Tang031018). Paratypes: 1♂18♀♀, same data as holotype (Tang031018).

Etymology.

The specific epithet is derived from the Latin adjective " uncatus " (hook-shaped), referring to the hook-shaped distal suprategular apophysis.

Diagnosis.

The new species resembles Himalaphantes lingulatus sp. nov. (Figs 3 View Figure 3 - 6 View Figure 6 ) but can be distinguished by the following characters: (1) proximal cymbial apophysis narrowing posteriorly in prolateral view in H. uncatus sp. nov. (Fig. 7A View Figure 7 ), whereas somewhat rectangular in H. lingulatus sp. nov. (Fig. 4A View Figure 4 ); (2) anterior pocket of paracymbium triangular in retrolateral view in H. uncatus sp. nov. (Fig. 7B View Figure 7 ), whereas somewhat cymbiform in H. lingulatus sp. nov. (Fig. 4B View Figure 4 ); (3) posterior margin of proscapus with a deep inverted V-shaped depression in H. uncatus sp. nov. (Fig. 8A-C View Figure 8 ), whereas with a transverse arc-shaped depression in H. lingulatus sp. nov. (Fig. 5A-C View Figure 5 ); (4) stretcher almost as long as wide, posterior margin slightly depressed medially in dorsal view in H. uncatus sp. nov. (Fig. 8B View Figure 8 ), whereas much longer than wide, with rounded end in H. lingulatus sp. nov. (Fig. 5B View Figure 5 ).
