Remarks. This species is still known only from females and the material studied herein, differs from the redescription of Lonsdale & Marshall (2016) in the following characters: (i) head with narrow brownish stripe from ocellar tubercle to anterior third of frons; (ii) anepisternum dark brown with whitish dorsal stripe; (iii) katepisternum dark brown with whitish yellow spot at posterodorsal margin; (iv) mid coxa with anterior half dark brown and posterior half yellow; (v) hind coxa partially brown and yellow; (vi) mid and hind femora with diffuse brownish distomedial rings (Fig. 20); (vii) abdominal tergite 5 with broad dark brown area laterally, fusing to the posterome- dial brown spot; (viii) tergite 6 brownish yellow with narrow lateral area dark brown. Lonsdale & Marshall (2016) did not mention the color of palpus, however we note that it is dark brown, unlike other species in the genus except N. biguttatus Wulp, 1896 .
