Nigeria specimens (as Crematogaster ?
gabonensis, Taylor, 1979: 29). WORKER. TL 4.01 mm, HL 0.90, HW
0.96, SL 0.67, PW 0.56
Colour of entire body orange-brown, except the gaster which is very
dark red-brown. Mildly striate on the mesonotum and propodeum.
Moderately dense pilosity and moderately abundant erect hairs. Profile
of pro- and mesonotum convex, metanotal groove impressed. Propodeal
spines long, acute and slightly upturned. Subpetiolar spine minute but
This seems a good match, although perhaps larger, for zavattarii;
alternatively or perhaps a synonym is nigeriensis although that
appears from Santschi's description to have shorter propodeal spines.
Nests in dead wood both on
the ground and on living trees building carton nests around and under
flaky, cankerous bark (right, clickable image).
Can be a dominant species on cocoa, found on up to 2% of
trees throughout the cocoa-growing area of Nigeria (Taylor,
1977). Tends Homoptera and builds carton tents to protect them (Taylor
& Griffin, 1981). Also found on native shrubs and trees, and on
cashew and kola.
