Diagnosis

(Figs 20 - 30 ). A medium-sized species separated from the similar P. fulvifacies Hering largely by the black face in males; length of male (4.29-4.47 mm), of female (5.45-5.49 mm). This species was adequately described by Hardy (1973) except for detailed structures of male and female postabdomen. Epandrium broad, not demarcated from surstylus (profile view); proctiger smaller than epandrium. Epandrium and surstyli elongate oval in posterior view; prensisetae well developed. Phallus elongate (2.71 mm); glans with a sclerotised rod. Oviscape (1.21 mm) dark brown to black, dorsoventrally flattened; eversible membrane shorter than oviscape (0.96 mm) with conical spicules in the proximal region and triangular spicules towards distal end. Aculeus (1.01 mm) as long as eversible membrane and with triangulate apex. Spermatheca elongate oval with numerous papillae.

Distribution.

This species is known from India (Karnataka, Tamil Nadu and Kerala) and Sri Lanka to Cambodia ( Hancock 2012).

DNA Barcode.

NCBI GenBank accession number - MT019891 (1♂, India: Karnataka, Bangalore, Attur, 29.v.2019, Sachin, K.).
