Male genitalia: Pygofer dorsal appendage not extended beyond caudal margin of lobe, little curved ventrally, with apex sharp (Fig. 3). Pygofer ventral appendage long and slim, branched about 1/3 distance from apex, dorsal branch long, ventral branch extremely short (Fig. 3). Subgenital plate with 3 macrosetae on outer surface and row of short setae along upper margin, basal setae of row longer than distal setae (Fig. 3). Style tapering towards apex (Fig. 4). Aedeagus wide in lateral view, with pair of small lateral processes arising near midlength of shaft; gonopore apical on ventral surface (Figs 5, 6).

Specimen examined. Holotype: ♂, CHINA, Hainan Prov., Jianfengling, 800~ 900m, 12-VII-2007, coll. Qiongzhang Song. Paratype: 2♂♂, 2♀♀, same data as holotype.

Measurement. Body length males 2.9–3.0 mm, females 3.1–3.3 (including wing).

Remarks. This species is similar to Salka fujiwara Chiang & Knight (1990), but differs in having the aedeagus with a pair of small processes arising from the middle of the aedeagal shaft laterally (Figs 5, 6); the pygofer ventral appendage bifurcate 1/3 distance from the apex (Fig. 3); and the apex of the style long and tapered (Fig. 4).

Etymology. The specific name is derived from the Latin word “ aciculus ”, referring to the aedeagus with one paired small appendage (Figs 5, 6).
