Holotype. Male. PAPUA NEW GUINEA: Rosenti - Dorich. Deposited in Rijksmuseum van Natuurlijke Historie.
Diagnosis. Distinguished by relatively short labium, profemora armed with 7+ ventral barbs, proctiger of male slightly swollen distally ( Fig. 19F View FIGURE 19 ), outer ventral rim of pygophore without medial process ( Fig. 19D View FIGURE 19 ).
Description. Body 2X longer than broad ( Fig. 16F View FIGURE 16 ). Vertex of head slightly convex, punctate. Juga apically acute, rounded laterally, swollen. Juga slightly longer than tylus. First antennal segment surpassing apex of head. Eyes stalked; posterior margins convex. Pronotum subrugose; anterolateral margins crenulate; lateral angles acute. Scutellum swollen anteriorly; apex narrowly pointed. Laterotergites with posterior angles weakly produced into small rounded tubercles.
Bucculae produced, becoming obsolete before reaching posterior margin of head; anterior angle of bucculae acute, directed anteroventrally. Labial ratios 1:1.5:1.5:? (segment IV broken off). Peritreme 1/4 as long as distance from ostiole of metathoracic scent gland to lateral margin of metapleuron. Episternal ridge located 2/ 3 of distance between ostiole of metathoracic scent gland and lateral margin of metapleuron. Venter of abdomen primarily convex; median flat on segments II–III. Profemora with 7–8 ventral thorn–shaped spines; spines becoming larger on distal portions.
Color and vestiture. Ground color straminous to testaceous with black shining punctures. Antennal segments I–III testaceous with piceous markings, segments IV–V piceous. Legs mostly straminous; tibiae with two castaneous bands on longitudinal ridges. Abdomen mostly straminous, spiracles black. Antennal segments I–II and proximal portion of segment III shiny with sparse vestiture; remainder of segment III and segments IV–V with dense short pile.
Male. Ventral rim of pygophore posteriorly produced, convex; dorsal rim with two short lateral lobes ( Fig. 19D–F View FIGURE 19 ). Proctiger elongate, becoming narrowed distally though distal portion slightly expanded; basal sclerite sinuate on posterior margin, anterior margin convex ( Fig. 19F View FIGURE 19 ).
Measurements. Male (n=1): body length 17.4, anterior pronotal width 3.4, humeral width 8.8, scutellar length 6.0, medial length of sixth sternite (fifth visible) 1.4, medial length of seventh sternite (sixth visible) 2.3. Appendages in Table 3.
Etymology. From the Latin adjective sphaeroides — round, spherical; referring to the spherical shape of the pygophore.
Distribution. New Guinea
