is known only from a few localities in Madagascar: the P.N. Andringitra
, P.C. Ankazomivady
, P.N. Befotaka-Midongy
and R.S. Kalambatritra
. All of these localities are mountainous regions in the southern Central Region and harbour mid-elevation to montane rainforest; Crematogaster sabatra
has been collected only from elevations of 1250 m and above (up to 1700m).
Little information exists on the biology of Crematogaster sabatra
. Workers of this species were mostly collected while beating vegetation and through other ground sampling methods. On a few occasions colonies were found in dead branches or twigs and carton nests, but queens or males were not collected and remain unknown. It seems likely that C. sabatra
shares a very similar arboreal lifestyle as the rest of the Malagasy Decacrema.
- Antennae 10-segmented
postero-laterally distinctly angular to tuberculate
- Promesonotal suture usually
- Large to very
large species (HW 1.151.31,WL 1.201.34)
spines medium to large size, usually with SPI > 0.22
- Head and
aciculate, reticulate to weakly costulate
is very closely related to the Crematogaster hova-
complex, from which it can be distinguished by size, the angular postero-lateral character of the mesonotum and the reduced sculpture. This species is further morphologically very similar to Crematogaster mahery
, from which it can be separated in the overlapping distribution range by the more pronounced sculpture and the incomplete promesonotal suture.
