Etymology.­­­ This species is named in honor of Dr. Jong-Seok Park, a fellow specialist of New Zealand pselaphines and supporter of this research.
Diagnosis.­­­ Externally, P. parki can be distinguished from all others in the genus by the presence of the apical flange on the apex of the median depression on ventrite II. The form of the aedeagus, with two ventral processes is also 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 three facets. Frontal margin of rostrum rounded, with sparse suberect setae in dorsal view. Gular mound modified, longer than wide, narrowed anteriorly and posteriorly, glabrous; area of head posterior to gular mound flattened, slightly concave, nude. Maxillary palpomere IV longer than head, narrow, widened at base and distal 1/6, apical area smooth, 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, raised into tumosity; metacoxae separated by extension of ventrite I. Legs unmodified. Elytra with two basal foveae, sutural fovea present; discal stria absent, sutural striae present. Abdomen:­­­ tergites of usual form for tribe. Ventrite I covered in dense, glossy setae; ventrite II with basal sulcus occupying length of ventrite, sulcus densely setose, deep ovate median depression reaching apex, sub apically with small flange projecting anteriorly back over depression. Genitalia: aedeagus asymmetrical. Median lobe simple. Dorsal processes short, curved inwards. Lateral processes absent. Two ventral processes present, as long as median lobe. Parameres absent.
Females.­­­Integument,­­­Head,­­­Thorax,­­­Abdomen:­­­ females of this species are unknown.
