2. Ground colour of forewing golden with indistinct white fasciae, without a distinct margin ( Fig. 22 )........... 02. mayumbe

– Ground colour of forewing reddish ochreous brown with distinct white fasciae, with rather wide blackish irregular edging basally ( Fig. 24 )........................................................................... 04. pentadesma

Key to the species of the Afrotropical Neolithocolletis based on male genitalia

– Valva elongate, slender, narrow, more than 6× long than broad, both margins running almost parallel to each other, slightly puffed caudally, with two large barbs at cucullus; aedoeagus straight; sternum VIII spatulate, long, significantly longer than vinculum ( Figs 144–146 )..................................................................... 02. mayumbe

2. Costal margin of valva shallowly concave in apical third, apex round with a blunt angle at costal side; sternum VIII small subpentagonal ( Fig. 149 )...................................................................... 04. pentadesma

– Valva elongate, rather broad, with dilating cucullus, costal and ventral margins of valva gently distancing from each other and united in rounded apex; sternum VIII very small, semi-rounded, slightly longer than broad ( Fig. 147 )...........03. nsengai

Key to the species of the Afrotropical Neolithocolletis based on female genitalia*

1. Segment VII strongly sclerotized on cephalic margin; sterigmatic sclerotizations on sternum VII absent; corpus bursae sparsely covered with acute spinules on inner surface except at caudal and cephalic ends ( Figs 293, 294 )........... 04. pentadesma

– Segment VII not sclerotized on cephalic margin, arc-shaped strongly sclerotized seam extends along entire sternum VII, acute spinules on inner surface of corpus bursae absent, caudal part of corpus bursae ringed with narrow sclerotized curled line ( Fig. 292 )........................................................................................03. nsengai

* female genitalia of N. mayumbe unknown.
