( Figs. 46–49 View Figs )

Diagnosis. – Aedeagal median rod submedially with slender, apically somewhat asymmetric process ( Fig. 49 View Figs ); aedeagal ventral bridge slender, apically largely bifurcated, sometimes with 1 or 2 small acute projections on dorso-subapical margin; aedeagal basal bridge with flap bearing 1 large and 1 small acute projections antero- and mediodorsally, respectively ( Fig. 49 View Figs ).

Material examined. – Holotype male, MALAYSIA: Poring, Sabah, coll. M. J. Toda, 30 Dec.1998 ( KPSP) . Paratypes: MALAYSIA: 3 males, same data as holotype except for 17 Mar.1999 (terminalia dissected, KPSP), 24 Mar.1999 ( ITBC), 3 Oct.1999 ( SEHU); Ulu Senagang, Crocker Range , Sabah , 4 males ( 1 male terminalia dissected), coll. M. J. Toda, 18 Oct.1999 ( FRIM, KPSP, SCAU, ITBC) .

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

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

Wing: Hyaline.

Legs: All femora 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. 18 setae on dorsal to posterolateral portion per side ( Fig. 46 View Figs ). Surstylus with pubescence basally and several wedge-shaped prensisetae on apical margin to inner surface ( Fig. 47 View Figs ). Additional plate between cerci and 10th sternite pubescent, medially connected to 10th sternite ( Fig. 48 View Figs ). Posterolateral lobe of hypandrium undeveloped. Paramere expanded distally; apical process with 1 sensillum; medial process with 1 sensillum and 1 tooth; proximal process pubescent ( Fig. 49 View Figs ). Vertical process of gonopods apically with 4-5 sclerotized projections per side ( Fig. 49 View Figs ). Aedeagus with 2 pairs of bridges ( Fig. 49 View Figs ).

Etymology. – From the Latin word “palmatus”, meaning palm, referring to the palm-shaped vertical process of gonopods.

Distribution. – Malaysia ( Sabah).

Remarks. – This species is very similar to P. ( P.) kinabalensis in the morphology of male terminalia, especially of the aedeagal basal bridge, but can be distinguished from it by the diagnostic characters.
