Brasura sinistra sp. nov.

( Figs 1, 3, 5 , 13–21 )

Description. Measurements. Male body length 9.54 mm; head width 2.47 mm; crown length×width 0.78× 0.94 mm; eye width 0.87 mm; frontoclypeus length 1.89 mm; clypellus length 1.13 mm; pronotum length×width 1.00× 2.90 mm; mesonotum+scutellum length 1.76 mm. Female unknown.

Crown light brown with pair of slightly darker maculae mesad of posteromedial eye corners ( Fig. 1 ). Pronotum piceous with dense light brown granules ( Fig. 1 ). Forewings piceous with light brown spots along veins, central area with numerous tiny pale spots ( Figs 1, 5 ). Crown, pronotum and mesonotum midline ratio about 1:1.28:2.26.

Male genitalia. Pygofer in lateral view with caudoventral digitiform process short, caudodorsal margin with small, broad lobe ( Fig. 14 ). Segment X broad, lateral margins slightly conveX ( Fig. 13 ). Aedeagus slender, slightly swollen at base and apeX, constricted medially; shaft with numerous short spines basally in ventral and lateral view ( Figs 15, 17 ); apical third with elongate, distally trifurcate retrorse lobe on left side, and 2 small setiform spines on right side ( Fig. 16 ); apeX with 2 short spines on each side; gonopore subbasal, among group of ventral spines ( Fig. 15 ). Dorsal connective narrow and straight in lateral view ( Fig. 17 ), broad in dorsal view ( Fig. 20 ). Style short, tapered distally ( Fig. 18 ). Connective triangular basally, with anterior arm long and rolled apically ( Fig. 19 ). Subgenital plate slender, inner margin straight, outer margin conveX medially, apeX rounded with fine setae ( Fig. 21 ).

Material examined. Holotype male, Republic of the Congo: Department Pool, Lesio-Loun Wildlife Reserve , 3°16.196′S 15°28.287′E, 340m, 27 Oct. 2008, coll. M. Braet and M. Sharkey.

Etymology. The new species name is a Latin word, meaning “left”, referring to the spine eXtended from the left side of the aedeagal shaft.

Remarks. This species is close to B. torquea Nielson and B. evaginata Nielson , but can be easily distinguished by aedeagus with elongate subapical process, 2 subapical spines at one side and 4 spines apically on the shaft, the latter two species with subapical process broad and short, seta-like spines numerous or absent at distal 2/3 of shaft, without apical spines.
