M. K. Tan (dried pinned, ZRC).

Female description. Similar to male in habitus ( Fig. 4A ). Tenth abdominal tergite with posterior margin deeply notched in the middle, with lateral lobe triangular ( Fig. 4B ). Epiproct small and obtusely rounded, with two small basal lobes ( Fig. 4B ). Cercus slender and cylindrical, apical end narrowed abruptly into an obtuse apex ( Fig. 4C ). Subgenital plate transverse, wider than long; with posterior margin broadly notched in the middle ( Fig. 4D ). Ovipositor long with base slightly swollen; straight in middle and apical third before tapering to an acute apex ( Fig. 4E ). Valves smooth; ventral and dorsal valves equal length, ventral valve more curved towards apex than dorsal valve ( Fig. 4E ).

Colouration. Similar to male.

Measurement (in mm). BL = 8.2, BWL = 21.8, PL = 3.8, TL = 15.4, HWT = 3.0, HFL = 9.8, HTL = 11.8, OL = 7.9.

Comparison. The female of this species differs from congeners by the posterior of subgenital plate distinctly notched in the middle.

The female subgenital plate differs from congeners with known females: P. bella bella Gorochov, 2008 from Mount Trus Madi, Borneo (oval, with distinct transverse fold and hardly notched apex instead); P. bella lambir Gorochov, 2014 from Lambir Hills, Borneo (oval, with slightly pointed apex instead); P. mima Gorochov, 2014 from Tawau Hills, Borneo (oval with rounded apex instead); P. parallela curup Gorochov, 2014 from Sumatra (with distinct median groove on posterior half instead); P. picta (Karny, 1924) from Java (with rounded apex instead); P. raggei (Bey-Bienko, 1971) from Mount Dulit, Borneo (triangular with acute apex instead); and P. spinea Gorochov 2014 from Sumatra (oval, with slightly pointed apex instead).

Female of P. sundaica (Kästner, 1932) and P. (S.) subtilissima Gorochov, 2008 are unknown.
