*Ceratrichia fako Sáfián & Tropek, 2016

Ceratrichia fako Sáfián & Tropek, 2016. Zootaxa 4150 (2): 128 (123-132).

Type locality: Cameroon: PlantiCam camp, the main tourist trail, south-western slope of Mount Cameroon, South-West Province, Cameroon; 23.XI–18.XII.2014. Leg.: Sáfián, Sz. & Tropek, R. Gen. prep.: SAFI00079. Coordinates: 04.117° N, 09.073°E; 1100 m. Holotype (male) in the A.B.R.I., Nairobi, Kenya. Diagnosis: “C. fako is obviously closely related to C. lewisi and the recently described C. manengouba, with the following differences, which are consistent over the large available series. The hindwing upperside of both sexes of C. lewisi has an extensive yellow patch along the outer margin, covering almost half of the wing, which is missing completely from C. fako, replaced by an overlay of dense golden-brown scales. Uppersides of both wings of C. fako, and especially the hindwing, are slightly overlaid by golden-brown scales, distinguishing it from both of its relatives. The ground colour of C. manengouba is generally darker; in its description, Larsen & Collins (2014) state that: “Upperside of both sets of wings uniformly deep black”; while the ground colour of C. fako is significantly lighter—it is a warm dark chocolate brown.” (Sáfián & Tropek, 2016). Etymology: Named for the local name of Mount Cameroon, the type locality.

7 Distribution: Cameroon.

Distribution: Cameroon. Specific localities: Cameroon – Mount Cameroon (TL); Buea-Bokwaongo trail (1 700 m), Mt Cameroon (Sáfián & Tropek, 2016).
