2. Laminaris cuspidatima Cao & Dietrich sp. nov.

( Figs 2 , 24 e–h)

Description. Ground color white, heavily infused with light brown (specimens preserved in ethanol before examination), eyes grey. Basal triangles of mesonotum black. Forewing light brown apically near costal margin. ( Figs 24 e–h)

Anal tube appendage ( Fig. 2c ) greatly expanded medially, apex blunt.

Pygofer side ( Fig. 2b ) rounded distally; dorsal appendage ( Figs 2b, c ) long, surpassing hind margin of lobe, foot-like, apex pointed. Subgenital plate ( Figs 2b, e ) relatively short, base much wider than apex; with about 4 macrosetae. Style ( Figs 2f, g ) with apical part sinuate in dorsal view, sharply curved ventrad in lateral view, middle part very short. Connective ( Fig. 2h ) with length slightly greater than width, lateral arms slightly sinuate. Aedeagal shaft ( Figs 2i, j ) broad, curved dorsad, with 2 small lamellae on ventral margin near middle; dorsal apodeme and preatrium short, region between preatrium and dorsal apodeme much wider than base of shaft in caudal view; gonopore subapical, concave in lateral view.

Measurement. Male length 3.30–3.40mm.

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

Etymology. The new specific epithet is derived from Latin adverb “ cuspidatim ” which means “like a spearpoint”, referring to the pointed pygofer dorsal appendage.

Diagnosis. The new species is similar to L. serrata sp. nov., but the anal tube appendage is blunt apically, the pygofer dorsal appendage is foot-like and much longer, the style is curved sharply and the aedeagal shaft has only 2 small ventral lamellae.
