( Figs. 41–45 View Figs )

Diagnosis. – Aedeagal median rod submedially with slender, apically asymmetric, slightly sclerotized process ( Fig. 44 View Figs ); aedeagal basal bridge with long, sclerotized, apically pointed projection anteroventrally, and large flap bearing 2 small acute projections antero- and mediodorsally ( Fig. 44 View Figs ).

Material examined. – Holotype male (terminalia dissected), MALAYSIA: Park Headquarters, Mt. Kinabalu , Sabah, coll. M. J. Toda, 2 Oct.1999 ( KPSP) . Paratypes: MALAYSIA: Mahua, Crocker Range , Sabah, 2 males (terminalia dissected), coll. M. J. Toda, 16 Oct.1999 ( SEHU, ITBC) .

Description. – Male. Head: Frons brown on upper half, dark brown on lower half.

Thorax: Orange yellow. Scutellum with trifurcate dark brown patch, pale yellow on tip.

Wing: Hyaline.

Legs: Foreleg femur only partly brown. Midleg tibia subapically with 3-4 longer setae on anterior surface.

Abdomen: First to fifth tergites yellow; second tergite with brown patches submedially; third to fifth tergites each with medially slightly protruded, brown band on posterior margin and 1 pair of yellow patches laterally; sixth tergite nearly entirely dark except yellow medial line, with expanded lobe on lateral margin.

Male terminalia: Epandrium pubescent anteroventrally and dorsomedially, with ca. 15 setae on dorsal to posterolateral portion per side ( Fig. 41 View Figs ). Surstylus with pubescence basally and several wedge-shaped prensisetae on apical margin to inner surface ( Fig. 42 View Figs ). Additional plate between cerci and 10th sternite pubescent, medially connected to 10th sternite ( Fig. 43 View Figs ). Posterolateral lobe of hypandrium undeveloped. Paramere expanded distally; apical process with 1 sensillum; medial process with 2 teeth; proximal process pubescent ( Fig. 45 View Figs ). Vertical process of gonopods apically with 4-6 sclerotized projections per side ( Fig. 44 View Figs ). Aedeagus with 2 pairs of bridges; ventral bridge slender, apically somewhat truncate ( Fig. 44 View Figs ).
