Diagnosis. Metacarp about 4× its distance from apex of marginal cell; inner spur of hind tibia markedly longer than outer one; postscutellum with an emargination between its middle point and forwarding-pointing projection, phragma exposed; scutellar sulcus reduced to a fine groove in which there is no obvious foveolation; apical part of T1 and T2 strongly to weakly rugose; T3 virtually entirely smooth, shiny; T1 markedly narrowing towards apex; T2 more transverse; hind coxa almost infuscate more or less throughout; antenna rather more noticeably longer than body compared with P. laetus ; ovipositor sheath shorter, only 3/4 length of hind basitarsus; and ocelli small, distance between fore and a hind ocellus slightly greater than diameter of hind ocellus.
