Material examined . – Holotype male (terminalia dissected), MALAYSIA : Park Headquarters, Mt. Kinabalu , Sabah , coll. M. J. Toda , 11 Mar.1999 ( KPSP ) . Paratype : 1 male , same data as holotype ( SEHU ) . Description. – Male. Head: Frons brown with large triangular black patch on upper half. Thorax: Orange yellow. Scutellum with triangular brownishblack patch. Wing: Slightly smoky on anterior margin. Legs: All femora dark brown except apical portions. Midleg tibia subapically with 2-4 longer setae on anterior surface. Abdomem: First to fifth tergites yellow; second to fifth tergites each with brownish black band on posterior margin and 1 pair of yellow patches anterolaterally; caudal band medially broadly interrupted on second tergite, but protruded on third to fifth; sixth tergite nearly entirely black except yellow medial line. Figs. 6–10. Phortica ( Phortica ) ni Chen & Toda, new species , male: 6, sixth tergite in ventral view; 7, epandrium and cercus in lateral view; 8, surstylus in frontal view; 9, tenth sternite and additional plate in frontal view; 10, hypandrium, gonopod, paramere and aedeagus in lateral view. Male terminalia: Epandrium lacking pubescence anteroventrally, with 9 setae on dorsal to posterolateral portion per side ( Fig. 7 ). Surstylus lacking pubescence, with several, apically rounded prensisetae ( Fig. 8 ). Additional plate between cerci and 10th sternite pubescent, medially connected to 10th sternite ( Fig. 9 ). Posterolateral lobe of hypandrium pubescent ( Fig. 10 ). Aedeagal median rod with knot subapically and 1 pair of bridges basally ( Fig. 10 ). Female: Unknown. Measurements: BL = 4.06 mm in holotype ( 1 male paratype : 4.57); ThL = 2.13 mm (2.06); WL = 3.32 mm (3.36); WW = 1.40 mm (1.48).

Etymology . – In reference to the paramere looking like Greek letter ‘niu’ in lateral view. Distribution . – Malaysia ( Sabah ). Remarks . – This species is very similar to P . ( P .) biprotrusa (Chen & Toda, 1998) from Yunnan , China , in the male sixth tergite with prickly process at the anteroventral corner, but can be distinguished from it by the posteroventral corners of male sixth tergite (in P . biprotrusa : with 2 prickly projections per side).
