Pselaphogenius fimbria Owens ­­­&­­­Carlton,­­­sp.­­­nov.

(Fig. 12a–c)

Type­­­ Material.­­­ Holotype: (1­­­ male)­­­ NEW ZEALAND ND Parahaki Park 5 Nov 1981 G. Kuschel // litter and decayed wood 81/126 (NZAC). Paratypes:­­­(1­­­male,­­­2­­­females)­­­ holotype locality (NZAC).

Etymology.­­­ The specific epithet refers to the fimbriate process present on the male aedeagus.

Diagnosis.­­­ Externally, P. fimbria is difficult to distinguish from the other species of Pselaphogenius in New Zealand. The form of the aedeagus, with the median lobe associated with a fimbriate process and the right lateral process curled, 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 four facets. Frontal margin of rostrum rounded, with sparse suberect setae in dorsal view. Gular mound modified, as long as wide, glabrous; area of head posterior to gular mound flattened, slightly concave, nude. Maxillary palpomere IV as long as head, narrow, widened at base and distal 1/5 apical area lightly rugose, v-shaped sensory patches present. Thorax:­­­ pronotum basal sulcus absent, lateral antebasal foveae and median antebasal fovea minute, pit-like. Mesoventrite with median shield unmodified. Metaventrite afoveate; metacoxae separated by extension of ventrite I. Legs unmodified. Elytra with single basal fovea, sutural fovea present; discal stria and sutural striae present. Abdomen:­­­ tergites of usual form for tribe. Ventrite I covered in dense, shining setae; ventrite II with basal sulcus occupying length of ventrite, sulcus densely setose, shallow oval median depression not reaching apex. Genitalia: aedeagus asymmetrical. Median lobe short, blunt, associated with fimbriate process. Left lateral process curved ventrad, right lateral process curled over one rotation, then curved laterally to the right. Ventral process straight, short. Parameres present, as long as lateral processes.

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

Distribution.­­­ This species is known only from the type locality in ND
