Myrmecina andalas

No information about the biology of this species is available, except that specimens were collected in Sumatra, Indonesia, from leaf litter in secondary forests.

Identification
Myrmecina andalas is morphologically most similar to Myrmecina magnificens among the species known from Sundaland. However, it is distinguishable from the latter by the following characteristics of worker:
 * ventrolateral area of head (temple + gena) smooth and shiny
 * anterior pair of denticles on propodeal dorsum very small and short (distinct in M. magnificens)
 * propodeal spine triangular, much shorter than broad at base and pointing dorsad
 * propodeal declivity vertical, with posterodorsal angle almost 90°
 * sternopostpetiolar process absent.

Worker of M. andalas also resembles that of Myrmecina nipponica. However, it is easily separated from the latter by the much larger eye that is more than twice as long as the antennal pedicel (vs. eye small, as long as pedicel), long erect setae on scape, some of which are 1.5 times as long as scape width (vs. most erect setae very short, not longer than scape length), and the propodeal lobe dorsally roundly convex (vs. in shape of a narrow strip).
