Crematogaster (Sphaerocrema) bequaerti mutabilis
Type location Kenya (Cremastogaster
Bequaerti For. var. mutabilis
nov., Santschi, 1914b:
93,
illustrated, worker) from Kenya, Lumbwa
|
A form smaller than the type, with more horizontal
propodeal spines, a
shallower metanotal groove, and, the front of the head shinier.
Bernard (1952) listed 4 workers of this form, variety mutabilis,
"known solely from Congo and eastern Africa", as collected in Guinea,
Mt. Nimba, at station T 40, Ziéla, from a termite hill (Lamotte); also
one alate queen from Camp IV, 1000 m.
Santschi's (1914b) illustrated description of mutabilis
is at . Santschi's
(1915c) added the variety mutabilis
Santschi is lighter than the type. In his 1937a key it was separated
under - head and alitrunk yellow more or less reddish, gatser
brownish. However, he nowhere provided any size.
Santschi's (1937a)
key to the varieties is on .
Noticeable in my (1979) drawing and the Cameroun
specimens shown below is the decumbent hairs on the gaster

Nigeria specimens (Taylor, 1979: 29). WORKER.
TL
3.02 mm, HL 0.75, HW 0.75, SL 0.65, PW 0.47
Colour brown, shiny. Sculpturation of slight striations on the lateral
alitrunk. Pilosity moderate, erect hairs few. Alitrunk profile flat,
metanotal groove not impressed but the propodeum is on a lower level
and the posterior face of the mesonotum is angled. Propodeal spines
long, straight, flat and acute. Subpetiolar spine blunt.
In Nigeria it nests in dead branch ends on
trees and in mummified cherelles (small aborted pods) on cocoa. Found
on up to 1% of cocoa, often in association with Oecophylla longinoda
(Taylor, 1977). Tends aphids on cocoa flowers. Also found on native
shrubs and trees.

In Ghana, Belshaw & Bolton (1994b) found it,
as a 'tourist', in leaf litter samples at three locations (primary
forest at Atewa Forest Reserve, secondary forest at Bunso, and cocoa at
Asiakwa) in the semi-deciduous forest zone.
