Diagnosis
This species resembles P. cophenius Senglet, 2008 (see Senglet 2008: 365, figs 57–65) in having similar male chelicerae (Fig. 6D), appendix (Fig. 6C), and female external genitalia (Fig. 6A), but can be distinguished by slightly thicker male pedipalpal trochanter (Fig. 5 A–B), by absence of distal sclerites on less curved procursus (Fig. 5 C–D), by more elongate uncus (Fig. 6C) (Huber 2011b), and by more elongate vulval pore plates (Fig. 6B).

PEDIPALPS. As in Fig. 5 A–B; trochanter with long curved ventral apophysis; femur with small dorsal apophysis proximally and small ventral modification; procursus simple proximally but complex distally, with two prolatero-dorsal spines; uncus with scaly edge; appendix with scales distally and flat prolateral process; embolus short and weakly sclerotized, with some transparent projections distally. Retrolateral trichobothrium of tibia I at 6%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae; tarsus I with approximately 5 distinct pseudosegments.
