12, female, dorsal view; 13, female internal reproductive structures, ventral view; 14, male, dorsolateral view.
Head: First flagellomere covered by pale microsetulae. Frontal vitta uniformly brown, without a darkened spot anterior to ocellar plate. Frontal vitta flat, not swollen anterior to ocellar plate. Epicephala converging, not immediately merging posterior to ocellar plate (
Fig. 15
). Epicephalon somewhat swollen above frontal vitta level.
Thorax: Mesonotum with lines of thin brownish microsetulae. Anterior half of postpronotal lobe bare. Femur covered with sparse black microsetulae. Mid and hind tibia cylindrical, without sulcus on outer face. Female cervical sclerite brown and smooth, without swelling. Cell r
4+5
open at the tip of the wing.
Abdomen: Single spermathecal duct smooth and with a rounded swelling apically. Single spermatheca cylindrical. Paired spermathecal duct broad on apical half and with an apical rounded swelling (
Fig. 16
). Paired spermathecal duct stems gradually broadened on apical half. Paired spermathecae oval with an apical nipple-like swelling.

Comments:
P. caliensis
is distinct for its wide and brownish vertex posterior to the ocellar plate and anterior to the postvertical setae. The unusual broadened paired spermathecal duct is also remarkable.
