[ Colotis rogersi Dixey, 1915 ]

Larsen 1996: pl. 7, figs 69 i. d’ Abrera 1997: 85 (3 figs).

Not included by Kielland (1990) as a member of the Tanzanian fauna, this taxon was originally described from Taveta (type material in OUMNH, K. St Aubyn Rogers). Talbot (1939, p.205) gives records of rogersi from the coastal area of Kenya south to central Tanzania (various localities to the west of Dar es Salaam, up to a maximum recorded height of about 1800 m). More widely, C. rogersi is now considered to extend to northern Kenya, southern Ethiopia and southeastern Sudan ( Ackery et al. 1995). Neither Ackery et al. (1995) nor d’ Abrera (1997) seem to have been aware that Taveta is in the south of Kenya, on the border between Kenya and Tanzania, and only a few kilometres east of Moshi. Larsen (1996) encountered this species in Kibwezi. Given this and the Taveta type locality, the presence of this butterfly on the lower slopes of Kilimanjaro seems likely. However, Talbot’ s (1939) records do not list Kilimanjaro. Using the DNA barcode, Nazari et al. (2011, p.211) were unable to separate material identified as C. rogersi from C. euippe , and they urged further investigation into this nominal species (while noting that “misidentifications could not be ruled out”). Given all these uncertainties, C. rogersi is not formally included here.
