1. Nsesa cameroonica Cao & Zhang sp. nov.

( Figs 21 , 27 m–p)

Description. Ground color pale yellow, eyes grey, gena pale, basal triangles of mesonotum dark brown. ( Figs 27 m–p)

Pygofer dorsal appendage ( Figs 21d, e ) large, base extended dorsad then directed ventrad, basal part long, apical part bifurcated, upper branch thinner and shorter than lower branch. Subgenital plate ( Figs 21d, g ) without macroseta, with numerous fine setae marginally. Style ( Fig. 21h ) with apical part sinuated. Connective ( Fig. 21h ) with central lobe, convex on apical margin. Aedeagus ( Figs 21i, j ) simple, apex extended on dorsal side, pointed; dorsal apodeme short; gonopore subapical.

Measurement. Male length 5.60mm.

Material examined. Holotype: ♂, CAMEROON: Adamaoua ; Mbam et Djerem National Park; WCS Guest-house; N6º 12' 08.1" E 12º 44' 41.7"; 15-30.iii.2009; J. R. Cryan & G.J. Svenson,

Etymology. The new species is named for the type locality “ Cameroon ”.

Diagnosis. The new species is similar to N. mpanza Dworakowska, 1974 , but the pygofer lobe is longer, the pygofer dorsal appendage is thinner and has longer upper branch, the subgenital plates lack macrosetae, the aedeagal shaft is thinner and lacks process.
