Figs 45–57

Diagnosis

This species can be easily indentified by vertex showing three brown parallel longitudinal bands ( Fig. 48 ); aedeagus bearing two pairs of ventral processes, ventral anterior processes strongly curved and antero-dorsally oriented, ventral posterior processes long and nearly straight with apex oriented dorsally ( Figs 55 , 57 ).

Etymology

The dorsal margin of the periandrium being shaped like a curly bracket, the name is made from a concatenation of two Latin words: parenthesis meaning “bracket” and flexuosa meaning “sinuous”.

Type material

Holotype CHINA: ♂, Menglun , Xishuangbanna, Yunnan Province, N 21º53′993′′, E 101º16′810′′, 611 m, 19 Aug. 2007, coll. Guo Zheng ( IZCAS).

Paratypes CHINA: 2 ♂♂, same data as holotype ( IZCAS).

Description

Length, male (including tegmina) (n = 3): 10.5–11.0 mm.

Vertex in dorsal view 1.1 times longer in midline than wide at base; apical margin slightly concave; lateral margins slightly excavate. Frons 1.7 times longer in midline than widest part, 2.9 times longer in midline than wide at base; sublateral carinae parallel and elevated, fused dorso-apically and forming an acute angle. Pronotum 3.7 times broader at widest part than long in midline. Mesonotum 1.0 times broader at base than long in midline. Tegmina 2.8 times longer at longest part than broad.

Coloration

Vertex ochraceous, with three brown paralleled longitudinal bands ( Fig. 48 ). Eyes grey ( Fig. 48 ). Frons protrusion in front of vertex in dorsal view ochraceous, with one brown transverse band at middle and several dark brown patches on each side ( Fig. 48 ). Frons ochraceous; sublateral carinae brown, with 7 brown patches on each side along outer rim of sublateral carinae; lateral margins brown ( Fig. 49 ). Ocelli tawny. Genae ochraceous. Pronotum ochraceous, with curved brown band along lateral carinae and three brown longitudinal stripes in lateral area on each side; carinae ochraceous ( Fig. 48 ). Mesonotum tawny, median and lateral carinae pale yellow ( Fig. 48 ). Tegmina dark tawny; costal margin with several brown oblique transverse stripes; apical part with one sinuate brown stripe at tip ( Figs 45–46 ). Legs ochraceous.

Male terminalia

Pygofer higher than wide in profile, with dorsal margin sloping down posteriorly on the ¼ of anterior part; postero-dorsal angle truncated; posterior margin slightly concave medially ( Fig. 50 ). Anal tube in dorsal view longer than wide, cylindrical, with apical margin rounded ( Fig. 53 ). In lateral view, gonostylus approximately as broad as high; dorsal margin slightly sinuate, on the upper anterior side a very small lateral process curving down, ventro-posterior margin oblique ( Figs 50, 54 ). In lateral view, dorsal margin of periandrium “curly brackets” shaped ( Figs 55–56 ). Aedeagus bearing two pairs of ventral processes, ventral anterior processes hidden in the periandrium folds, strongly curved and antero-dorsally oriented, ventral posterior processes nearly straight with apex oriented dorsally ( Figs 55 , 57 ).
