Figs 4–5 View Fig View Fig , 6G–J View Fig


Male pygofer ( Fig. 4F View Fig ) with dorsal margin strongly excavated; macrosetae located on apical half, forming longitudinal row. Subgenital plate ( Fig. 4F–G View Fig ) ligulate, with tuft of filiform setae near apex on dorsal surface. Style ( Fig. 4H–I View Fig ) with apex acute, more sclerotized and curved outwards. Aedeagus ( Fig. 4J–K View Fig ) with dorsal apodeme with pair of long, claviform processes; shaft tubular with pair of long apical processes directed anteroventrally. Female sternite VII ( Fig. 5B–C View Fig ) with posterior margin with broad median lobe, rounded and emarginated medially.


The species name refers to its flattened body ( Fig. 6H, J View Fig ).

MEASUREMENTS. Total length: male 13.0– 13.7 mm (n =2); female 16.8 mm (n =1). COLORATION. Male yellow ( Fig. 6G–J View Fig ) without markings. Female with face ( Fig. 5A View Fig ) with dark band adjacent to margin of crown.

HEAD AND THORAX. External morphological characters as in generic description.

MALE TERMINALIA. Sternite VIII ( Fig. 4E View Fig ) subrectangular, about 1.3 times as wide as long; lateral margins parallel, posterior margin slightly rounded. Valve subrectangular, 2.3 times as wide as long; posterior margin convex. Pygofer in lateral view ( Fig. 4F View Fig ) moderately produced posteriorly, about 1.7 times as long as maximum height, without processes; dorsal margin strongly excavated; less than 10 macrosetae forming a longitudinal row, near dorsal margin of apical half; apex tapered and rounded. Subgenital plate, in lateral view ( Fig. 4F View Fig ), produced posteriorly as far as pygofer apex; in ventral view ( Fig. 4G View Fig ), ligulate, about 3.6 times as long as wide; ventral surface covered by small setae; dorsal surface with tuft of moderately long filiform setae near apex; lateral margins divergent towards apex; apex abruptly tapered and rounded. Connective ( Fig. 4H View Fig ) with anterior portion membranous, posterior portion sclerotized; approximately one-seventh length of style; arms narrow, strongly divergent. Style in dorsal view ( Fig. 4H View Fig ) with outer lobe poorly developed; in lateral view ( Fig. 4I View Fig ), with margins parallel; ventral margin smooth; apex acute, more sclerotized and curved outwards. Aedeagus ( Fig. 4J–K View Fig ) with preatrium absent; atrium expanded posteriorly; dorsal apodeme well developed; apodemal processes claviform, extending to apex of shaft, subapical region of each process rounded and with preapical excavation dorsally; shaft elongated and tubular, curved dorsally; apex with pair of processes parallel to shaft, extending anteroventrally, half-length of shaft, each process with inner margin crenulate and apex acute.

FEMALE TERMINALIA. Sternite VII ( Fig. 5B–C View Fig ) 2.3 times as wide as long; posterolateral angles developed and subacute; posterior margin with broad median lobe, rounded and emarginated medially. Internal sternite VIII membranous. Pygofer ( Fig. 5D View Fig ) elongate, about 1.5 times as long as maximum height; apex rounded; few macrosetae distributed near apex and ventral margin. First valvifer ( Fig. 5E View Fig ) subtriangular. First valvula of ovipositor ( Fig. 5E View Fig ) slightly curved dorsally; about seven times as long as high; slightly higher on median third; dorsal sculptured area beginning at basal third; apex ( Fig. 5F View Fig ) with dorsal and ventral sculptured areas strigate; blade apex acute. Second valvifer ( Fig. 5D View Fig ) higher than long. Second valvula of ovipositor ( Fig. 5G View Fig ) slightly higher medially; approximately 7.5 times as long as maximum height; median third with dorsal triangular protuberance; apical portion ( Fig. 5H View Fig ) with large preapical tooth; blade apex tapered and acute. Gonoplac ( Fig. 5D View Fig ) 5.4 times as long as high; dorsoapical margin long and straight; apex rounded.
