Genus Crematogaster - Subgenus Eucrema
Genus Crematogaster Introduction

Subgenus Eucrema Santschi (1918d: 182)

Diagnostic Features - Antenna with a 3-segmented club. Frontal carinae well developed. Petiole with parallel sides, usually straight or scarcely arcuate, rarely broader posteriorly than anteriorly. Postpetiole more or less impressed.

Santschi's (1918d) subgenus description is at {original description}.

All five species listed by Bolton (1995) are Neotropical; so the following seems likely to be an erroneous separation, possibly a member of the subgenus Orthocrema, see below.

Crematogaster (Eucrema) species 1

Entire dorsum of alitrunk longitudinally concave. Spines of propodeum very long. Listed by Bolton (unpublished key, 1969) as found at CRIN, Nigeria.

Bolton's sketch of the lateral alitrunk profile, specially the points at the posterior of the promesonotum, suggests that the specimens may have been Crematogaster (Orthocrema) pulchella (or pauciseta).
