    Malagasy

Distribution Notes:

MADAGASCAR
Collections of Crematogaster malala are rare, with only a few colonies from montane rainforest (>1250m) at three locations in the Ankaratra (Ankazomivady), Andringitra and Midongy massifs.

Biology:

The few collections of Crematogaster malala workers document these ants as nesting in dead twigs and in carton nests; queens or males of this species have not yet been discovered. A recent search for C. malala in the P.N. Andringitra at about 1800m, not far from where it had been collected before, was unsuccessful and suggests that these ants might be highly restricted in habitat and possess very inconspicuous habits.

Identification:

  • Antenna 10-segmented
  • Petiole dorsally with postero-lateral tubercles, each bearing a single stiff and long erect seta
  • Postpetiole distinctly bilobed and broadly medially impressed, with a pair of dorso-posterior stiff, long erect setae
  • Abdominal tergites 4-7 usually with scattered erect pilosity
  • Lateral portions of promesonotum postero-laterally rounded or angular
  • In lateral view promesonotum forming a more or less convex outline
  • Mandibles with 4 teeth
  • Rare, montane forests of southern central Madagascar
