Diagnosis. – The new species resembles Onomastus complexipalpis Wanless, 1980   ( Wanless, 1980b: 187, Fig. 4 View Fig ) in the shape of male palp, but can be distinguished from the latter in abdomen with pairs of dark spots dorsally ( Fig. 1A View Fig ); median apophysis of male palp wide in basal part, with a middle curved flange, and spur of embolic guide shorter and wider ( Fig. 1 View Fig B-D). It is also similar to Onomastus nigricaudus Simon, 1900   ( Wanless, 1980b: 181, fig. 1A-G) in male palp with a femoral apophysis, but differs from the latter in abdomen with pairs of dark spots dorsally ( Fig. 1A View Fig ); median apophysis of male palp not branched, with distal part thin and dagger shaped, spur of embolic guide wide ( Fig. 1 View Fig B-D); female epigynum with a median septum which widened posteriorly, and spermatheca connected with an oval structure anteriorly, which is doubted to be the copulatory duct ( Fig. 1E, F View Fig ). It can also be distinguished from Onomastus kanoi Ono, 1995   ( Ono, 1995: 157, figs. 16-21) by the long and thin distal part of median apophysis, smaller embolic guide, larger spur of embolic guide and blunt femoral apophysis of male palp ( Fig. 1 View Fig B-D).

Retrolateral surface of distal femur I, prolateral and retrolateral surface of distal tibiae with a black patch respectively. Spination of leg I: metatarsi v 4- 2-0, p 1-0-0, r 1-0-0; tibiae v 4-4-4, p 1-0-0, r 1-0-0, d 0-1- 0; patellae v 0-1-0, r 0-1-0; femora p 0-0-1, r 0-0-1, d 1-1- 1.

Other characters similar to those of male. Median septum of epigynum ( Fig. 1E, F View Fig ) widened posteriorly, spermatheca small.

Etymology. – The specific name is from the Latin “nigri+maculatus”, and refers to the dorsal dark patches on abdomen.
