Diagnosis.­­­ Externally, P. jiaweii is similar to other species in the genus, Pselaphogenius , in NZ. The form of the genitalia, with the laterally compressed and distally expanded ventral process and elongate and laterally compressed median lobe is unique.

Description.­­­ MALE holotype. ­­­Integument: head, pronotum, elytra, abdomen, and appendages light brown, palpi lighter in color. Head:­­­ width between eyes equal to ½ length of head from base of vertex to apex of rostrum. Eyes small, composed of six facets. Frontal margin of rostrum emarginate in dorsal view, with sparse suberect setae. Gular mound modified, longer than wide, narrowed anteriorly and posteriorly, glabrous; area of head posterior to gular mound flattened, slightly concave, bearing sparse setae. Maxillary palpomere IV longer than head, narrow, widened at base and distal 1/5, apical area smooth, v-shaped sensory patches present, row of ventral tubercles along length. Thorax:­­­ pronotum basal sulcus absent, lateral antebasal foveae absent, median antebasal fovea minute, pit-like. Mesoventrite with median shield unmodified. Metaventrite afoveate, produced into tumosity with patch of golden setae; metacoxae separated by extension of ventrite I. Legs unmodified. Elytra with one basal fovea, sutural fovea present; discal stria present, sutural striae present. Abdomen:­­­ tergites of usual form for tribe. Ventrite I covered in dense, shining setae; ventrite II with basal sulcus occupying width of ventrite, sulcus densely setose, ovate median shallow, narrow, not reaching apex of ventrite. Genitalia: aedeagus symmetrical. Median lobe laterally compressed, slightly expanded and curved dordsad, distally. Inner and outer lateral processes short, straight, simple. Ventral process laterally compressed, ventrally curved and distally expanded. Parameres present, as long as median lobe and ventral process.

Females.­­­Integument,­­­Head,­­­Thorax,­­­Abdomen:­­­ similar to male except eyes slightly smaller and ventrite II lacking median ovate depression.

Distribution.­­­ This species is known from several localities in BP. Additionally, P. jiaweii is known from two localities in GB.
