Style ( Figs 1h, i View FIGURE 1 ) with apical part straight in dorsal view, curved ventrad in lateral view, middle part short. Connective ( Fig. 1j View FIGURE 1 ) narrow, length greater than width.

Material examined. Holotype: ♂, REPUBLIC OF CONGO, Dept. Pool, Iboubikro site, Lesio-Loun Pk, 340m, 03°16.196'S, 015°28.267'E, 23.viii.2008, coll. Braet & Sharkey. GoogleMaps Paratypes: 1♂, same data as holotype GoogleMaps ; 2♂, same data except 25.viii.2008 GoogleMaps ; 1♂, same data except 03°16.020'S, 015°31.440'E, 19–26.viii.2008 GoogleMaps .

Etymology. The new specific epithet is derived from Latin adjective “ angustus ” which means narrow, referring to the narrow anal tube appendage.

Diagnosis. This species can be distinguished from the others by the anal tube appendages of uniform width and the straight aedeagal shaft.
