Charaxes (Eriboea) berkeleyi marci Congdon and Collins, 1998


Charaxes (Eriboea) berkeleyi marci Congdon and Collins, 1998  

Congdon and Collins 1998: pl. 2, fig. 11 (both sexes). SI: Figure 16a – d.

Forewing length (estimated from photographs): male 31 – 36 mm [mean (n = 4) 33.3 mm, SD = 1.372]; female 32 – 43 mm [mean (n = 6) 38.4 mm, SD = 3.248].

Note: The female differs from other subspecies on the forewing upperside, on which the postdiscal spotting is reduced, and on the hindwing upperside, which has the discal band broader. In females of marci, the bands on the upperside of both wings are the same colour, whereas other subspecies have the hindwing markings paler than those of the forewings ( Congdon and Collins 1998, p. 52).


The type locality is ‘ West Mt Kilimanjaro, 7000 ft. ’ Collected in March 1993 by S.C. Collins, the type series (three males, six females, with one additional male) is in the African Butterfly Research Institute, Nairobi. Endemic to Kilimanjaro, and known only from the type locality ( Congdon and Collins 1998, p. 52), it was not encountered by Liseki (2009). The two other recognized subspecies of C. berkeleyi van Someren and Jackson, 1957   , are restricted to highland forests in Kenya ( Ackery et al. 1995, p. 435).
