Charaxes (Eriboea) baumanni tenuis van Someren, 1971

Henning 1989: 251 (2 figs). SI: Figure 13e – h.

Forewing length: male 25.5 – 30.5 mm [mean (n = 12) 27.81 mm, SD = 1.241]; female 28 – 33.5 mm [mean (n = 6) 30.88 mm, SD = 1.326]. van Someren (1971, p. 219) gave male forewing length as 27 – 31 mm, female 30 – 31 mm.

Records

The Northern Highlands, including Oldeani-Ngorongoro Range, Mt Meru, Mt Kilimanjaro, Longido, Mbulu Forests, Mt Kwaraha and Lolkisale, at 1400 – 2000 m ( Kielland 1990, p. 96). The population from Lolkisale is intermediate to the nominate subspecies ( Kielland 1990, loc. cit.). Henning (1989, p. 252) notes Moshi and Arusha (probably based on van Someren 1971, p. 219). In OUMNH there is a female from the slopes of Kilimanjaro, December 1905, and a male from Taveta, c. 2500 ft, both collected by Rogers. The BMNH has three males collected by Cooper at Engare- Nairobi, West Kilimanjaro, at 4000 – 5000 ft, February – March 1937, a male from Old Moshi collected by Selous, and a female labelled ‘ Kilimandjaro ’ ex Rogenhofer ex Honrath ex Adams that could have been part of the original type series of Charaxes baumanni Rogenhofer (the restricted type locality of which nominal species is the Pare Mountains). Although not encountered by Liseki (2009), it might conceivably enter the lowest forest zone on Kilimanjaro – although, according to Kielland (loc. cit.), it is found in open forests and shrublands. Outside Tanzania subspecies tenuis occurs in Kenya (highlands east of Rift Valley). Collectively, the 10 subspecies of C. baumanni Rogenhofer, 1891 , listed by Ackery et al. (1995, p. 434) range widely in eastern Africa, from southern Sudan to Mozambique.
