Diagnosis. Coleophora camerunensis   is a small, dark brown species, with a lighter narrow line along the costa. It belongs to a group of species that includes C. presbytica Meyrick, 1921   and C. etoshae Baldizzone & van der Wolf, 2011   , which share the same habitus. The genitalia are very similar in all three, but in the male of C. camerunensis   the dorsal part of the juxta rods is in the shape of an obtuse angle rather than an arrow tip like, as in the other species, In C. camerunensis   the cornutus is long, thin, and needle-shaped, whereas C. etoshae   has two short and curved cornuti, joined at the base to form a claw ( Fig. 41 View FIGURES 36–41 ), and C. presbytica   has a very long, thin and curved cornutus ( Fig. 40 View FIGURES 36–41 ). In the female genitalia, the most comspicuous distinguishing characteristic is the spinulate part of the ductus bursae: in C. etoshae   there are no spinose parts in the transparent ductus ( Fig. 44 View FIGURES 42–44 ), and C. presbytica   has the ductus with the spinose area twice as long as that of C. camerunensis   sp. nov., and the spines completely envelop the ductus ( Fig. 42 View FIGURES 42–44 ), whereas those of the new species are arranged in two short bands; moreover, in the proximal part of the colliculum, there is also a short, but evident median line, absent in the other two species.

Description. Wingspan 8–10 mm. Head brown, tinged white over compound eye. Antennae ringed dirty-white and dark brown; scape without tuft of erect scales. Labial palpus white on inner side and almost completely brown on outer side; second segment about 0.5 times as long as third. Proboscis normal, slightly longer than labial palpus. Thorax brown. Tegula brown, lighter on inner edge. Forewing brown, with a white costal line that widens towards apex, where it terminates before fringe; costal fringe hazelnut, dorsal fringe light brown. Hindwing and fringe greyish brown. Abdomen brown.

Male genitalia ( Figs. 36, 37, 39 View FIGURES 36–41 ): Gnathos knob oval. Tegumen broad, narrow in middle, pedunculus slightly dilated. Transtilla short, oval, joined in center. Valvula small, oblong, well sclerotized. Cucullus short, ear-shaped Sacculus curved and jagged on lateral edge, with short protuberance in dorsal corner. Phallotheca with two juxta rods more sclerotized in dorsal part, and bent at an angle in central part. Cornutus thin and curved with wider base.

Female genitalia ( Fig. 43 View FIGURES 42–44 ): Papillae anales oval. Apophysis posterioris twice as long as anterioris. Sterigma trapezoidal, about 1.5 as wide as long, distal margin curved. Ostium bursae broad. Colliculum transparent in proximal part, with short small medial line, and broad, more sclerotized and cup-shaped in distal part. Ductus bursae very long, thin and transparent, with some convolutions in proximal half and with small spines covering distal part which is as long as sterigma. Corpus bursae an elongated, oval sack with leaf-shaped signum.

Abdominal structures ( Fig. 38 View FIGURES 36–41 ): No posterior lateral struts. Transverse strut almost straight, with thicker proximal edge. Tergal disk about 4.5 times longer than wide, covered by 15 conical spines.

Bionomy. The early stages and the foodplant are unknown.

Distribution. The species is known only from Cameroon.

Etymology. The name derives from the country in which the specimens were collected.
