Head: Frons brown with large triangular black patch on upper half. Thorax: Orange yellow. Scutellum with trifurcate brown patch, yellowish white on tip. Wing: Slightly smoky. Legs: All femora partly brownish. Midleg tibia subapically lacking longer setae on anterior surface. Abdomen: First to fifth tergites yellow; second tergite with black patches submedially and laterally; third tergite with medially and laterally slightly protruded, sublaterally nearly interrupted, brown band on posterior margin; fourth and fifth tergites each with medially and laterally slightly protruded, brown band on posterior margin and 1 pair of small yellow patches sublaterally; sixth tergite nearly entirely black except yellow medial line. Male terminalia: Epandrium pubescent anteroventrally and dorsomedially, with 7 setae near dorsal to posterolateral margin per side ( Fig. 16 ). Surstylus lacking pubescence, with several wedge-shaped prensisetae on apical margin to inner surface ( Fig. 17 ). Additional plate between cerci and 10th sternite pubescent, medially connected to 10th sternite ( Fig. 18 ). Posterolateral lobe of hypandrium large, lacking pubescence ( Fig. 19 ). Paramere lacking pubescence; apical process with 3 teeth apically and 1 sensillum subapically; median process triangular; proximal process slender, with 1 sensillum apically ( Fig. 19 ). Vertical process of gonopods nearly triangular ( Fig. 19 ). Aedeagal median rod apically with 2 pairs of (inner longer and outer small) triangular processes, subbasally with 1 pair of small processes; outer membranous tube convoluted apically, with transparent minute spinules subapically and basally ( Fig. 19 ). Aedeagus with 1 pair of looped bridges basally ( Fig. 19 ). Female: Unknown. Measurements: BL = 3.75 mm in holotype (range in 4 male paratypes : 3.52-3.87); ThL = 1.78 mm (1.69-1.83); WL = 3.17 mm (2.80-3.40); WW = 1.40 mm (1.24-1.36).

Etymology. – Patronym, in honor of Dr. Francis Liew of the Sabah Parks, Malaysia . Distribution . – Malaysia ( Sabah ). Remarks . – This species is similar to P. ( P .) linae (Máca & Chen, in Máca & Lin, 1993) from Taiwan and central China in the morphology of phallic organs, but can be distinguished from it by the aedeagal median rod (in P. linae : aedeagal median rod subapically with 1 pair of asymmetric or only 1 triangular projection(s) in addition to 1 pair of submedial long projections).
