Pararhinoleucophenga amnicola sp. nov.

( Fig. 4 )

Diagnosis. This species is related to P. maura (de Meijere, 1911) from Java and Sumatra, Indonesia in the male terminalia, but can be distinguished by the epandrium with several setae near posterior margin only ( Fig. 4A ); cercus with short setae ( Fig. 4A, B ); aedeagus acute apically, lacking lobe-like processes ventrobasally ( Fig. 4C ).

Description. Only characters that depart from the universal description given by Cao & Chen (2009) for this group are provided for brevity. Male. Eye brownish red. Pedicel and first flagellomere brownish. Face brown laterally, dark brown medially; facial carina black. Palpus dark brown. Thorax brownish yellow, with unapparent, dark brown longitudinal stripes. Katepisternun dark brown, with 1 row of setae below katepisternal setae. Scutellum brownish yellow. Legs mostly brown; mid femur with 2 rows of strong setae on anterior surface. First to fourth abdominal tergites yellow except for black bands on posterior margins of second to fourth tergites; fifth and sixth tergites nearly entirely black. Abdominal sternites dark brown, longer than broad. Male terminalia: Surstylus with 8 prensisetae on inner margin of distal part ( Fig. 4B ). Cercus lacking ventral process ( Fig. 4B ). Hypandrium posterolaterally without pubescence; vertical flap (fla) of hypandrium with dense pubescence ( Fig. 4C, D ). Posteromedian plate of gonopod very narrow, arcuate ( Fig. 4D ). Paramere basally rod-like, distally flap-like and pubescent ( Fig. 4C, D ). Aedeagus robust, with dense, fine serrations: apodeme slender ( Fig. 4C, D ).
