DIAGNOSIS: Distinguished from P. dorsalis , n. sp., as given in the diagnosis above.
DESCRIPTION: Very similar to P. dorsalis with the exception of the following features: Head: Antenna with arista terminal, not dorsal-preapical. Male eyes large, holoptic for length of approximately 8 facets; ocellar triangle and small portion of frons exposed; no differentiation of facets; ocelli on low tubercle, close together. Thorax: Posteriormost notopleural seta very long and robust, ca. 2× the length and width of other notopleurals; 2 (vs. 1) postalar setae (anterior one finer). Transverse suture well developed. Anteriormost scutellar seta very small, length less than 0.3× that of adjacent scutellar seta (vs. approximately equal in size). Legs: Hind tibia with dorsal row of 6 stout, slightly curved setae, alternating with smaller stout setae. Wing: As drawn: longer, L/ W 1.89 (vs. 1.77), from tip to level of crossvein h. M 1 slightly more arched; microtrichia confined to wing margin. Terminalia: Epandrium glabrous, brown, apparently heavily sclerotized; laterally flattened (clamlike), with fine setae on inner edge; surstylus pendulous, setulose, curved and clavate, apparently articulating with ventrolateral portion of epandrium (not fused). Aedeagus and paraphallic structures not observable.
SPECIMENS EXAMINED: Holotype, male, AMNH Bu-SE2/6, in Burmese amber. In excellent condition.
ETYMOLOGY: In reference to the position of the arista on the basal flagellomere.
