Snelling, in NTM; 1 <i>„</i>, Ivimka camp, Lakekamu Basin, 7.73 <i>°</i> S, 146.76 <i>°</i> E, 110–200 m, 20–25 October 1996, R. R. Snelling, in LACM. <i>Distribution.</i> Known only from the Lakekamu Basin, Papua New Guinea (Figure 60). <i>Etymology.</i> The specific name is derived from Latin, and is a reference to the black setae found on most of the head and body. <i>Diagnosis.</i> Male: erect setae on head and mesosoma black. Parameres long and digitate apically and ending near the apex of the aedeagus (Figures 39, 40). Basiparameres (viewed dorsally) relatively narrow especially apically. <i>Description.</i> Male: black; metasoma (except T1 and S1) red suffused with black; flagellum dark yellow-brown; setae fulvous on head and metasoma, black on mesosoma, frons, vertex and gena with both decumbent fulvous setae and erect black setae; wings very weakly infuscate; veins and stigma light brown. Clypeus closely and finely punctate, apically truncate, sagittally carinate. Frons rugosely punctate. Vertex rugosely punctate. Gena finely rugosely punctate, subparallel, less than half length of minimum eye diameter. Occipital carina just visible dorsally. Genal cavity not visible dorsally. Pronotum and mesoscutum, mesoscutellum and metanotum rugosely punctate. Propodeum closely punctate. Mesopleura rugosely punctate. T1–6 almost impunctate except laterally; T7 closely and coarsely punctate, impunctate medially; T1 with length: width 1.5:1. S1 sparsely punctate; S2–8 almost impunctate except posteriorly. Hypopygium (Figure 32) subparallel, lateral spines acute, apical spine broadly subtriangular. Genitalia (Figures 39, 40) with parameres subparallel over most of length, apices slightly twisted, slightly divergent and appearing as a long digitate process in profile, ending at apex of aedeagus; basiparameres in dorsal view broadly triangular with preapical notch, apex narrowly rounded and clearly differentiated from aedeagus, ending before level of apices of cuspides, broad in lateral view; aedeagus with distinct basal and apical sections, basal section short and hidden below basiparameres, without ventral lobes, apical section straight, narrow, parallel, ending at level of apices of parameres. BL: 10–12; FW: 7–9; HW: 5–6.
