description: Phortica (Phortica) zeta Chen & Toda, new species   
(Figs. 30–35)  
  Diagnosis. –  Paramere medially much expanded, pubescent on submedial small part, distally with 2 processes: apical process with 1 sensillum and 3 small teeth apically; subapical process longer than apical one, with spine-shaped projection apically (Figs. 33, 34); aedeagal median rod subapically expanded and asymmetrical, with 1 pair of small acute projections submedially (Figs. 33, 35); aedeagal basal bridges asymmetric, tripartite, strongly sclerotized, but without small teeth except for triangular tip of anterior process (Fig. 33).   
  Material examined. –  Holotype male (terminalia dissected), MALAYSIA: Ulu Senagang, Crocker Range, Sabah, coll. M. J. Toda, 18 Oct.1999 (KPSP).   
  Decription. –  Male. Thorax: orange yellow. Scutellum with trifurcate brown patch, pale yellow on tip. Anepisternum with several setulae.   
Wing: Hyaline.  
Legs: All femora lacking patches. Midleg tibia subapically with 3–4 longer setae on anterior surface.  
Abdomen: First to fifth tergites yellow; second tergite with brownish black patches submedially; third to fifth tergites each with medially nearly interrupted, laterally protruded, black band on posterior margin and 1 pair of yellow patches laterally; sixth tergite nearly entirely black, narrowed on lateral margins, with a few long strong setae on posterolateral margins.  
Male terminalia: Epandrium pubescent anteroventrally and dorsomedially, with 8 setae on dorsal to posterolateral portion per side (Fig. 30). Surstylus pubescent, with dense setae medially and apically rounded prensisetae on inner margin (Fig. 31). Additional plate between cerci and 10th sternite pubescent, medially connected to 10th sternite (Fig. 32). Posterolateral lobe of hypandrium undeveloped. Aedeagus with 1 pair of bridges (Fig. 33).  
Female: Unknown.  
Measurements: BL = 3.78 mm in holotype; ThL = 1.94 mm; WL = 3.00 mm; WW = 1.28 mm.  
Indices: arb = 6/3, avd = 0.83, adf = 2.20, flw = 1.60, FW/ HW = 0.40, ch/o = 0.08, prorb = 1.15, rcorb = 0.50, vb = 0.35, dcl = 0.60, presctl = 0.80, sctl = 1.10, sterno = 0.95, orbito = 1.60, dcp = 0.24, sctlp = 1.10, C = 2.21, 4c = 1.36, 4v = 2.43, 5x = 0.88, ac = 3.80, M = 0.50, C3F = 0.74.  
  Etymology. –  In reference to the paramere looking like Greek letter ‘zeta’ in lateral view.   
  Distribution.  – Malaysia (Sabah).   
  Remarks.  – This species is very similar to P. (P.) eparmata (Okada, 1977) from Taiwan in the shape of paramere, but can be distinguished from it by the aedeagal median rod and the aedeagal basal bridge (in P. eparmata: aedeagal median rod much expanded apically, without submedial projections; aedeagal basal bridge with a few acute teeth).
