Body proportions and coloration as in generic description.

Male genitalia: Pygophore broad, rounded posteriorly, covered with macrosetae posteriorly and some at mid-ventral margin; posterior margin with triangular membranous process on inner apex, covered with minute setae. Subgenital plate elongate, extending beyond pygophore, narrowing to rounded apex, lateral margin sinuate, with numerous macrosetae. Connective Y-shaped, shaft robust, arms well developed. Style with basal half wide, narrowing to middle, apical half narrow. Aedeagus with well-developed basal projection from dorsal margin, tapered to acute apex, deeply concave at dorsal margin; shaft about as long as basal projection, with ventral triangular flange subapically and pair of lateral appendages, apically branched and with short process near midlength, phallotreme apical on ventral surface.

Material examined. China: Holotype ɗ, Fujian Prov., Wuyi Mountain, 7 August 1998, Yang Maofa (GZU). Other material: 1ɗ, Fujian Prov., Wuyi Mountain, Xianfengling, 21 July 2003, coll. Duan Yani (EM); 4Ψ, Fujian; Wuyi, Sangang, 17 Nov. 1980, coll. Chen Tong (EM); 1Ψ, Fujian; Longdu, Wuyishan Mountain, 21 Aug. 1988, coll. Yang Zhongqi (EM).

Remarks. This species resembles Abrus coneus Dai and Zhang externally, but can be distinguished from the latter by: 1) pygophore without long appendage at ventral posterior margin; 2) aedeagal shaft about as long as basal projection, with ventral triangular flange subapically; 3) aedeagal projection tapered to acute apex and deeply concave at dorsal margin.

Distribution. China (Fujian).
