Figs. 16–19. Phortica ( Phortica ) liewi Chen & Toda , new species , male: 16, epandrium and cercus in lateral view; 17, surstylus in frontal view; 18, tenth sternite and additional plate in frontal view; 19, hypandrium, gonopod, paramere and aedeagus in lateral view. Material examined . – Holotype male (terminalia dissected), MALAYSIA : Park Headquarters, Mt. Kinabalu , Sabah , coll. M. J. Toda , 11 Mar.1999 ( KPSP ). Description. – Male. Head: Frons brown. Arista without ventral branches. Thorax: Orange brown. Scutellum with trifurcate dark brown patch, pale on tip. Anepisternum lacking setulae. Wing: Slightly smoky on anterior margin. Legs: All femora brown except apical portions. Midleg tibia subapically with 3–4 longer setae on anterior surface. Abdomen: First to fifth tergites yellow; second tergite with black patches submedially; third to fifth tergites each with medially slightly protruded, sublaterally interrupted, black band on posterior margin; sixth tergite nearly entirely dark, pointed anterolaterally, with a few long strong setae on posterolateral margins ( Fig. 20 ). Male terminalia: Epandrium pubescent anteroventrally and dorsomedially, with 12 setae on dorsal to posterolateral portion per side ( Fig. 21 ). Surstylus pubescent, with dense setae medially and apically rounded prensisetae on inner margin ( Fig. 22 ). Additional plate between cerci and 10th sternite pubescent, medially connected to 10th sternite ( Fig. 23 ). Posterolateral lobe of hypandrium undeveloped. Paramere with 2 sensilla and 2 pointed teeth apically ( Fig. 24 ). Aedeagus with 1 pair of bridges ( Fig. 24 ). Female: Unknown. Measurements: BL = 4.00 mm in holotype ; ThL = 1.28 mm ; WL = 3.18 mm ; WW = 1.40 mm . Indices: arb = 3/0, adf = 1.80, flw = 1.30, FW/HW = 0.45, ch/o = 0.07, prorb = 1.10, rcorb = 0.45, vb = 0.40, dcl = 0.60, presctl = 0.80, sctl = 1.15, sterno = 0.90, orbito = 1.20, dcp = 0.23, sctlp = 1.00, C = 2.05, 4c = 1.47, 4v = 2.33, 5x = 0.70, ac = 3.67, M = 0.47, C3F = 0.73. Etymology. – In reference to the aedeagal basal bridge looking like Greek letter ‘epsilon’ in lateral view. Distribution. – Malaysia ( Sabah ). Figs. 20–25. Phortica ( Phortica ) epsilon Chen & Toda , new species , male: 20, sixth tergite in ventral view; 21, epandrium and cercus in lateral view; 22, surstylus in frontal view; 23, tenth sternite and additional plate in frontal view; 24, hypandrium, gonopod, paramere and aedeagus in lateral view; 25, tip of aedeagal median rod in ventral view. Remarks . – This species is very similar to P . ( P .) cardua ( Okada, 1977 ) in that the arista lacks ventral branches and the anepisternum lacking setulae, but can be distinguished from it by the aedeagal median rod and the paramere (in P. cardua : aedeagal median rod slender, unexpanded subapically; paramere pubescent distally).
