Pselaphogenius chandleri Owens ­­­&­­­Carlton,­­­sp.­­­nov. (Fig. 8a–c) Type­­­Material.­­­ Holotype: (1­­­male) New Zealand, BP Orete Forest Te Puia Hut 26 Apr 1993 G. Hall // Sifted litter 93/96 (NZAC). Paratypes:­­­(2­­­males,­­­3­­­females)­­­ holotype locality (NZAC). Etymology.­­­ This species is named after Donald. S. Chandler, fellow pselaphine worker, whose years of support to both authors has been much appreciated. Diagnosis.­­­ Externally, P. chandleri is difficult to distinguish from other species of Pselaphogenius in New Zealand. The form of the aedeagus, with the simple, straight, median lobe and the absence of lateral and ventral processes, 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 three facets. Frontal margin of rostrum narrowly rounded, with sparse suberect setae in dorsal view. Gular mound modified, longer than wide, broad anteriorly and narrowed posteriorly; area of head posterior to gular mound flattened, slightly concave, nude. Maxillary palpomere IV longer than head, narrow, widened at base and distal 1/5 to 1/6, v-shaped sensory patches present. Thorax:­­­ pronotum basal sulcus absent, lateral antebasal foveae and median antebasal fovea absent. Mesoventrite with median shield unmodified. Metaventrite afoveate, posterior margin with elongate setae extending to base of ventrite II, metacoxae separated by extension of ventrite I. Legs unmodified. Elytra with two basal foveae, single sutural fovea present; discal stria absent, 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 small, restricted to basal portion of ventrite. Genitalia: aedeagus asymmetrical. Median lobe straight, simple, slightly down-curved. Lateral processes absent. Ventral process absent. Parameres present, as long as median lobe. Females.­­­ Integument,­­­ Head,­­­Thorax,­­­Abdomen:­­­ similar to male except ventrite II lacking median ovate depression. Distribution.­­­ This species is known from several localities in BP.
