Head dark brown, lower portion of frons orange. Interfrontal bristles in four pairs. Thorax brown, shiny despite microtomentum. Anterior dorsocentral bristles separated by 8–9 rows of acrostichal setulae. Ventral surface of male mid tibia with two rows of stout setae along apical quarter; mid femur with two corresponding rows of proximoventral setae; female mid tibia with a large apicoventral bristle. Hind tibia with only fine dorsal setulae. Wing (Fig. 68C) hyaline, basally with a small, indistinct darker spot. R 2+3 almost straight with a slight sinuate curve about midlength. MALE ABDOMEN (Fig. 49). S5 simple, right side 1.5× as long as left, uniformly setose, and slightly desclerotized posteromedially. S6 long and thin. Epandrium relatively large, wedge-shaped and relatively sparsely setose, ventrolateral margins with two distinct emarginations (for hypandrial arm and for posterodorsal corner of surstylus); cercus large, flattened, and shiny, without any enlarged setae. Hypandrial arms stout basally. Surstylus large, inverted V-shaped: anterior lobe rectangular with an apical emargination, outer surface with two large preapical setae, inner surface with long setae and setulae, posterior lobe triangular with three long laterobasal setae and a row of long setae along entire ventral margin. Postgonite elongate, slender, slightly sinuate, apex slightly broadened and truncate. Phallapodeme long and gently curved; basiphallus tall, 3.1 × as tall as long in lateral view, slightly constricted subbasally with a small posterodorsal tooth. Distiphallus large, box-like, with a large, broad ventral sclerite, a pair of long, dorsoventrally flattened, hoop-like dorsolateral sclerites supporting the membranous sides, and curved, wedge-shaped apical sclerite; lateral membrane setulose. FEMALE ABDOMEN (Fig. 50). T7 desclerotized posteromedially. Epiproct broad, rectangular, emarginate anteromedially. Cercus semicircular with slightly thickened apical seta and two long preapical setae. S8 slightly desclerotized medially. Hypoproct trough-shaped. Spermathecae stout, subcylindrical, and lightly grooved with small apical invagination. Distribution Australasian/Oceanian: Cook Islands (new record), Fiji (new record), French Polynesia (Marquesas, Tahiti, Tubuai Is.) (Roháček et al. 2001), Hawaii (USA) (Tenorio 1967), Papua New Guinea (new record), Samoa, Tonga (Roháček et al. 2001). Remarks Given the apparent abundance of Ps. brevivenosum on most of the Pacific Islands from which we have sphaerocerid samples, it is likely that this species is also found throughout Polynesia.
