Material examined. LECTOTYPE: (here designated) „. Papua New Guinea: Central District : (type number 15.295), Mondo, 1524 m (5000 ft), February 1934, L. E. Cheesman, in BMNH.

Other material. PARALECTOTYPE: 1 „, same data as holotype dated January 1934, in BMNH .

Distribution. Known only from Mondo, Papua New Guinea ( Figure 60 ).

Diagnosis. Male: metasoma black with T 6–7 and S6–8, and the posterior and lateral margins of T 2–5 and S2–5, red-orange and the antennae black. The genitalia have the apical lobe of the parameres digitate, twisted, divergent and appearing as a short downturned digitate process in profile, ending beyond apex of aedeagus. Aedeagus short and ending before the apex of the parameres, and the basiparameres long (see Brown 2001: Figures 26, 27 ).

Description. Male: black; posterior and lateral margins of T 2–5 and S2–5, T 6–7 and S6–8 red-orange; tegulae testaceous, brown; tibial spurs orange; wings very weakly infuscate, veins brown; setae white becoming orange on apex of metasoma, pale yellow on dorsum of thorax and margin of genal cavity. Clypeus closely and finely punctate, apically truncate, sagittal carina obscure especially dorsally. Frons rugosely punctate. Vertex closely to rugosely punctate. Gena finely punctate, slightly oblique, less than half length of minimum eye diameter. Occipital carina just visible dorsally. Genal cavity not visible dorsally. Pronotum and mesoscutum rugosely punctate. Mesoscutellum closely to rugosely punctate. Metanotum finely punctate. Propodeum closely and shallowly punctate. Mesopleura closely and finely punctate, becoming coarser and rugose anterodorsally. T 1–5 almost impunctate; T 6 closely punctate, T 7 closely and coarsely punctate; T 1 with length: width 1.2:1. S1 shallowly and sparsely punctate; S2–8 almost impunctate but becoming punctate posterolaterally on posterior sternites especially S8. Hypopygium subovate, lateral spines short and acute, apical spine subtriangular. Genitalia with parameres subparallel over most of length, apices twisted, divergent and appearing as a short down-turned digitate process in profile, ending beyond apex of aedeagus; basiparameres in dorsal view broadly triangular with preapical notch, apex rounded, 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, apical section short, narrow and parallel without ventral lobes, ending before level of apices of parameres. BL: 11; FW: 9; HW: 7.

Remarks. The gena and genitalia illustrated as this species by Kimsey (1996) do not belong to this species ( Brown 2001).
