Camponotus (Myrmotrema) bayeri Forel

return to key {link to the Hymenoptera Name Server} Type location Zaïre (Camponotus (Myrmotrema) Bayeri n. sp., Forel, 1913h: 356, soldier only) collected at Karemi, by Bayer; soldier and minor known (see Bolton, 1995). Note bayeri ssp nigeriensis (Santschi, 1914) now is regarded as a subspecies of Camponotus perrisii .

Forel's (1913h) description is at {original description}.

Santschi's Key (1915c) separated the species by its having prismatic tibiae and scapes which are flattened but only moderately expanded from base to apex; plus a near trapezoidal clypeus. NOTE - I suspect that couplet 42 in Santschi's key is, at the least, unsatisfactory, or at worst, wrong, with the onward numbers transposed - as Wheeler's picture of perrisii ssp jucundus shows a very distinct trapezoidal clypeus. Thus bayeri would have a near rectangular clypeus. On the other hand, describing rhamses (from Egypt, and separated in the key from foraminosus), Santschi noted that has "clypeus is more distinctly trapezoidal than in foraminiceps but less narrowed posteriorly than bayeri". Similarly on C. puberulus, he noted "Emery writes that the major has a trapezoidal clypeus, as with the minor. C. bayeri is thus a very close form, characterised by the effacement of the hair pits on the genae".

Wheeler (1922) reported the Lang & Chapin expedition collected 13 workers from Faradje in Zaïre.

Bernard (1952) listed a single queen from Kéoulenta, Guinea which he ascribed to this species.
