3. Laminaris serrata Cao & Dietrich sp. nov.

( Figs 3 , 24 i–l)

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

Anal tube appendage ( Fig. 3c ) expanded subbasally, apex pointed and curved cephalad.

Pygofer side ( Fig. 3b ) truncate distally; dorsal appendage ( Figs 3b, c ) short, not extended to hind margin of lobe, blunt apically. Subgenital plate ( Figs 3b, e ) with long apical part curved dorsad, with about 5 macrosetae. Style ( Figs 3f, g ) with apical part straight in dorsal view, directed dorsad in lateral view, middle part relatively long. Connective ( Fig. 3h ) with length subequal to width. Aedeagal shaft ( Figs 3i, j ) broad, curved dorsad, dorsal edge with serrate lamella from base to middle, ventral margin with pair of triangular, serrate flanges; preatrium relatively long, region between preatrium and dorsal apodeme wider than base of shaft in caudal view; gonopore central.

Measurement. Male length 3.30–3.40mm.

Material examined. Holotype: ♂, REPUBLIC OF CONGO, Dept. Pool, Iboubikro site, Lesio-Loun Pk, 340m, 03°16.196'S, 015°28.267'E, 05.viii.2008, coll. Braet & Sharkey. Paratypes: 1♂, same data as holotype except 25.viii.2008 ; 1♂, same data except 18–28.viii.2008 ; 1♂, same data except 03°16.020'S, 015°31.440'E, 29.viii.2008 .

Etymology. The new specific epithet is derived from Latin adjective “ serratus ” which means saw-like, referring to the serrate flanges of the aedeagal shaft.

Diagnosis. The new species is similar to L. tenuis sp. nov., but the pygofer dorsal appendage is wider, the style has a wider apical part, the aedeagal shaft is much broader but shorter, and has three serrate flanges.
