P. obtusiclavatus sp. nov.

( figures 57, 58)

Diagnosis. Head with occiput sharply margined; post-occipital carina present ( figure 57). Scape at least partly dark; pedicel dark; funicular segments all longer than broad; clava about 1.2 times as long as broad, obtuse. Pronotum mostly dark, with two symmetrical yellow patches on dorsum ( figure 57). Scutellum smooth, with sublateral grooves narrow and not reaching posterior pair of scutellar setae. Dorsellum completely dark, including area laterally. Propodeal median carina raised anteriorly into a translucent, elongate and tongue-shaped protuberance ( figure 58).

Remarks. This species is very similar to P. natadae in having transparent, elongate, raised propodeal carina. But it differs from latter species by having a longitudinal, dark strip on scutellum, completely dark dorsellum and hind coxae, as well as F1 around 3 times as long as broad.

Description. Head mostly yellow with occiput and area around ocelli black; occipital carina present, developed into translucent lamina; post-occipital carina present; antennal scrobe black. Scape dark on dorsal margin; pedicel dark; flagellum concolorous, with all funicular segments longer than broad, not becoming shorter and broadened towards clava simultaneously; F1 1.7 times as long as broad; F4 samely separated from F3 and clava, and distinctly four-segmented. Clava medially same breadth as funicle, obtuse, around 1.2 times as long as broad.

Dark parts on mesosoma black. Pronotum with yellow parts occurring more than on posterior end, never translucent. Pronotum mostly dark, with two symmetrical yellow patches on dorsum, with distinct transverse carina anteriorly, without longitudinal, parallel, short carinae attaching to the transverse carina. Mid lobe of mesoscutum mostly dark, with large, median yellow patch posteriorly, with engraved reticulations, covered with setae all over the dorsum, without median longitudinal carina. Axillae mostly dark, with yellow patch near to inner corners, smooth and bare. Axillula completely dark. Scutellum with median, longitudinal, dark stripe, without longitudinal median carina, smooth; sublateral grooves narrow, not reaching posterior pair of scutellar setae. Area between sublateral grooves completely yellow, differing from the area lateral to the grooves, which latter area is smooth. Dorsellum completely dark including lateral area, smooth, without tooth-like structure directing posteriorly. Propodeum completely dark and smooth, with median carina at least translucent along margins, thus appearing yellow, raised anteriorly into a translucent, elongate and tongue-shaped protuberance, without short carinae attached. Petiole not apparent.

Hind coxae completely dark. Hind femora dark on dorsal margin. Hind tibiae yellow, with one tibial spur more than 1.5 times length of the first tarsomere. Hind tarsi with the first tarsomere fuscous, as long as the second.
