1. Laminaris angusta Cao & Dietrich sp. nov.

( Figs 1 , 24 a–d)

Description. Ground color white (specimens preserved in ethanol before examination), eyes grey, face with indistinct longitudinal brown medial band. Basal triangles of mesonotum brown. Forewing dark brown apically near costal margin. ( Figs 24 a–d)

Anal tube appendage ( Fig. 1e ) narrow, base curved, apex blunt, as wide as base.

Pygofer side ( Fig. 1d ) rounded distally; dorsal appendage ( Figs 1d, e ) short, not extended to hind margin of lobe, blunt apically. Subgenital plate ( Figs 1d, g ) with short apical part curved dorsad; with about 4 macrosetae. Style ( Figs 1h, i ) with apical part straight in dorsal view, curved ventrad in lateral view, middle part short. Connective ( Fig. 1j ) narrow, length greater than width. Aedeagal shaft ( Figs 1k, l ) narrow and straight; preatrium rudimentary, region between preatrium and dorsal apodeme slightly wider than base of shaft in caudal view; gonopore central.

Measurement. Male length 3.00mm.

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. Paratypes: 1♂, same data as holotype ; 2♂, same data except 25.viii.2008 ; 1♂, same data except 03°16.020'S, 015°31.440'E, 19–26.viii.2008 .

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.
