Diagnosis.

Male of P. mamillaris is similar to that of P. platembola Jäger, 2001 , in having a similar sickle-shaped embolus (E) and petal-shaped conductor (C). However, it can be distinguished from the latter by the following characteristics: (1) in ventral view, embolus (E) is apically rugged and as wide as its middle section (vs. apically not rugged, pointed) (cf. Figs 8 A View Figure 8 , 10 B View Figure 10 , and Jäger 2001: figs 35 b, g, i); (2) dorsal branch of RTA (dRTA) tip not curved (vs. slightly or distinctly curved) (cf. Figs 8 A, B View Figure 8 , 9 B View Figure 9 , 28 B View Figure 28 , and Jäger 2001: figs 35 a – c, f – h); (3) RTA inserted closer to cymbium (Cy), both dRTA and vRTA separated from cymbium (Cy) by approximately half of the tibial (Ti) diameter (vs. inserted farther, both dRTA and vRTA separated from cymbium (Cy) by more than one tibial (Ti) diameter) (cf. Figs 8 A, B View Figure 8 and Jäger 2001: figs 35 b, g). For the female diagnosis, see Zhang et al. (2023 a).

Tibia (Ti) moderately long, ca. 3 / 5 cymbium length, with retrolateral apophysis (RTA) arising mesially; RTA bifurcated, ɔ-shaped in retrolateral view, both ventral and dorsal branches distinctly protruding: dorsal branch (dRTA) finger-like, slightly curved and tapering, ca. 3 / 5 of tibia length, extending to cymbial base; ventral branch (vRTA) thumb-like, relatively short, ca. 1 / 2 length of dRTA, apex round. Cymbium (Cy) ca. 1.9 × longer than wide, cymbial bulge (CB) indistinct. Tegulum (T) oval, ca. 1.2 × longer than wide, posteriorly slightly bulged, slightly excavated on prolatero-apical side to accommodate embolus (E) and conductor (C); spermophor (Sp) sinuate, forming a loop along tegular margin.
