description: <i>Deuterothynnus fulvicentratus</i> sp. n. (Figures 11–13, 59) <i>Material examined.</i> HOLOTYPE: <i>„</i>. <b>Papua New Guinea</b>: Central District: Ivimka camp, Lakekamu Basin, 7.73 <i>°</i> S, 146.76 <i>°</i> E, 200 m, Mountain <i>#</i> 6, lowland rainforest, 11–20 November 1996, R. R. Snelling, in LACM. <i>Distribution.</i> Known only from lowland rainforest in the Lakekamu Basin, Papua New Guinea (Figure 59). <i>Etymology.</i> The specific name is a combination of the Latin words <i>fulvus</i> meaning redyellow and <i>centratus</i> meaning centre. It is a reference to the orange of the first two metasomal segments. <i>Diagnosis.</i> Male: metasoma black with first two metasomal segments orange; setae white. Margins of basiparameres (viewed dorsally) subparallel (Figures 11, 12). Apical filament of aedeagus convoluted and much longer than the length of the parameres. <i>Description.</i> Male: black; metasomal segments 1 and 2 orange; antennae brown; wings hyaline, veins brown; setae white. Clypeus closely and finely punctate, apically truncate, sagittal carina obscure over most of length. Frons and vertex rugosely punctate. Gena finely rugosely punctate, slightly oblique, less than half length of minimum eye diameter. Occipital carina visible dorsally. Genal cavity not visible dorsally. Pronotum including anterior surface, mesoscutum and mesoscutellum rugosely punctate. Metanotum impunctate. Propodeum rugosely punctate. Mesopleuron rugosely punctate. T1–6 almost impunctate, shallowly punctate laterally; T7 closely and coarsely punctate, medially impunctate; and T1 with length: width 2.6:1. S1 shallowly and sparsely punctate; and S2–8 almost impunctate but becoming punctate posterolaterally on posterior sternites. Hypopygium (Figure 13) with sides subparallel, broadly emarginate apically with large apical spine and smaller preapical spine laterad to emargination, weakly sclerotized medially. Genitalia (Figures 11, 12) with parameres broad and subparallel, dorsal margin almost straight over much of its length, ventral margin sinusoidal apically, apex slightly convergent, rounded, down-turned, ending beyond apex of aedeagus (when coiled); basiparameres in dorsal view with lateral margins subparallel over most of length becoming subtriangular apically, extreme base constricted, apex not clearly differentiated from aedeagus, apparently narrowly emarginate and ending slightly beyond level of apices of cuspides, broad in lateral view; aedeagus with basal and apical sections, basal section elongate-ovoid without ventral lobes, apical section very long, filamentous, coiled, much longer than length of parameres. BL: 8; FW: 6; HW: 4. <i>Remarks.</i> The left antenna is incomplete.
