4. Laminaris tenuis Cao & Dietrich sp. nov.

( Figs 4 , 24 m–p)

Description. Ground color white, heavily infused with light brown (specimens preserved in ethanol before examination), eyes grey. Basal triangles of mesonotum black. ( Figs 24 m–p)

Anal tube appendage ( Fig. 4c ) expanded medially, apical part narrow and curved cephalad, apex pointed.

Pygofer side ( Fig. 4b ) rounded distally; dorsal appendage ( Figs 4b, c ) short, not extended to hind margin of lobe, blunt apically. Subgenital plate ( Figs 4b, e ) with long apical part curved dorsad, with about 4 macrosetae. Style ( Figs 4f, g ) with apical part curved laterad in dorsal view and curved ventrad in lateral view, middle part short. Connective ( Fig. 4h ) with length slightly greater than width. Aedeagal shaft ( Figs 4i, j ) slender and long, curved dorsad, without flanges or processes, apex relatively wide; preatrium short, region between preatrium and dorsal apodeme wider than base of shaft in caudal view; gonopore subapical.

Measurement. Male length 3.30mm.

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 except 29.viii.2008 ; 1♂, same data except 05.viii.2008 ; 1♂, same data except 07–21.viii.2008 .

Etymology. The new specific epithet is derived from Latin adjective “ tenuis ” which means slender, thin, referring to the slender aedeagal shaft.

Diagnosis. The new species is similar to L. serrata sp. nov., but the anal tube appendage is narrower apically, the pygofer dorsal appendage and the apical part of the style are narrower, the aedeagal shaft is much thinner and longer, and lacks flanges.
