Material examined . – Holotype male, MALAYSIA : Pasoh, Selangor , Malaya, coll. N. Osawa , 2–9 May.1995 ( FRIM ). Decription. – Male. Thorax: Orange yellow. Scutellum with trifurcate brown patch, pale yellow on tip. Wing: Hyaline. Legs: All femora partly brown. Midleg tibia subapically with 2-4 longer setae on anterior surface. Abdomen: First to fifth tergites yellow; second tergite with brown patches submedially; third to fifth tergites each with medially slightly protruded, brown band on posterior margin and 1 pair of yellow patches laterally; sixth tergite nearly entirely dark except yellow medial line, with expanded lobe on lateral margin. Male terminalia: Epandrium pubescent anteroventrally and dorsomedially, with ca. 12 setae on dorsal to posterolateral portion per side ( Fig. 50 ). Surstylus with pubescence basally and several wedge-shaped prensisetae on apical margin to inner surface ( Fig. 51 ). Additional plate between cerci and 10th sternite pubescent, medially connected to 10th sternite ( Fig. 52 ). Posterolateral lobe of hypandrium undeveloped. Paramere expanded distally, pubescent between medial and proximal processes; apical process with 1 sensillum; medial process with 1 sensillum and 2 teeth ( Fig. 53 ). Vertical process of gonopods apically with 4-5 sclerotized projections per side ( Fig. 53 ). Aedeagus with 2 pairs of bridges ( Fig. 53 ). Female: Unknown. Measurements: BL = 3.47 mm in holotype ; ThL = 1.76 mm ; WL = 2.60 mm ; WW = 1.24 mm .

Etymology. – Pertaining to the type locality. Distribution . – Malaysia (Malaya). Remarks . – This species is very similar to P . ( P .) expansa in the morphology of male terminalia, but can be distinguished from it by the diagnostic characters.
