Phortica (Phortica) jamilii Chen & Toda , new species

( Figs. 11–15 )

Diagnosis. – Aedeagal median rod subapically with 1 pair of long slender projections and submedially with 1 pair of long, broad, apically bifurcated projections ( Fig. 15 ).

Material examined. – Holotype male (terminalia dissected), MALAYSIA: Park Headquarters, Mt. Kinabalu , Sabah, coll. M. J. Toda, 20 Mar.1999 ( KPSP) . Paratype: 1 male (terminalia dissected), same data as the holotype except for 7 Mar.2000 ( SEHU) .

Description. – Male. 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 almost brown. 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, extended below at posterolateral corners ( Fig. 11 ).

Male terminalia: Epandrium pubescent anteroventrally and dorsomedially, with ca. 14-15 setae near dorsal to posterolateral margin per side ( Fig. 12 ). Surstylus pubescent basally, with several wedge-shaped prensisetae on apical margin to inner surface ( Fig. 13 ). Additional plate between cerci and 10th sternite pubescent, medially connected to 10th sternite ( Fig. 14 ). Posterolateral lobe of hypandrium large, lacking pubescence ( Fig. 15 ). Paramere lacking pubescence; apical process with 3 teeth apically and 1 sensillum subapically; median process triangular; proximal process slender, with 1 sensillum apically ( Fig. 15 ). Vertical process of gonopods triangular lobe-like ( Fig. 15 ). Aedeagal median rod subbasally with 1 pair of small processes; outer membranous tube convoluted apically, with transparent minute spinules subapically and basally ( Fig. 15 ). Aedeagus with 1 pair of looped bridges basally ( Fig. 15 ).

Female: Unknown.

Measurements: BL = 4.20 mm in holotype (1 male paratype: 4.18); ThL = 1.94 mm (1.83); WL = 3.20 mm (3.08); WW = 1.36 mm (1.28).

Etymology. – Patronym, in honor of Dr. Jamili Nais of the Sabah Parks, Malaysia.

Distribution. – Malaysia (Sabah).

Remarks. – This species is similar to P. (P.) eugamma (Toda & Peng, 1990) from southern China in the pattern of abdominal tergites, but can be distinguished from it by the aedeagal median rod (in P. eugamma : aedeagal median rod subapically with 1 single, submedially with 1 paired, small, simple projections).
