( Figs. 15–16 View FIGURES 15–16 )

Description (female only): Body length 4 mm; wing 3,5 mm. Head and abdomen dark brown, thorax black. Palpus brown except for white outer face. Clypeus brown with sparse pale microsetulae. First flagellomere dark brown. Fronto-orbital plate dark brown. Row of katepisternal setae brownish. Fore tibia dark brown. Fore tarsus white and covered by brownish small setulae. Hind femur mostly dark brown, white on basal quarter and with a small angled preapical white ring. Tergites dark brown. Oviscape dark brown.

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 View FIGURES 15–16 ). 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 View FIGURES 15–16 ). Paired spermathecal duct stems gradually broadened on apical half. Paired spermathecae oval with an apical nipple-like swelling.

Type material: Holotype: COLOMBIA. Valle Del Cauca, PNN Farallones de Cali Anchicaya , 3º26’ N 76º48’ W, 650 m, Malaise, 1.VIII–10.X.2000, M. 1103, S.

Distribution: Colombia.

Etymology: The specific name is a reference to Cali, a city near the type locality.

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.
