Nos.: NHMUK014331135 (♂) (prepared by Volynkin), Arctiidae 43 (♀) (NHMUK); KENYA: 1 ♀, Western, Kakamega Forest, Rondo Retreat, 00°13'37''N 34°53'06''E, 1610m, Black / MV lights, 27.vii.2001, K. Maes leg. (ANHRT). Note. The type locality of the species, Akoafim is an abandoned German colonial town situated north of the Aïna River (Eckert 1912). Diagnosis. The forewing length is 10.0– 12.5 mm in males and 11.5–13.5 mm in females. Crocosia divisa is superficially very similar to the allopatric C. phaeocraspis and a detailed comparison is provided above in the diagnosis of the latter species. Distribution. The species is currently known from Cameroon, Gabon, Republic of Congo, Uganda, and western Kenya. It is also present in Democratic Republic of Congo based on a photograph examined of a specimen in RMCA (accessed at https://virtualcol.africamuseum.be). Kühne’s (2008, as Ilema mesosticta) record from Nigeria is highly likely based on the type locality of Cragiosia mesosticta, although it’s occurrence in southeastern Nigeria cannot be ruled out.
