 Overview --- Identification  Specimens --- References/Links  Nomenclature ---
This pan-tropical subfamily consists of only three genera, but two of them [Pseudomyrmex in the New World, and Tetraponera in the Old World] are diverse and abundant in most tropical woodlands and forests.  The third genus, Myrcidris, is monotypic and occurs in Brazil.  

 These ants are predominantly arboreal, though a few species nest in dead wood on the ground, and one or two are even found in termite nests.  In the New World tropics there are perhaps 150-200 Pseudomyrmex species.  Some are obligate inhabitants of specialized ant-plants, and a very few are social parasites, but the vast majority are free-living.

The subfamily Pseudomyrmecinae is represented in Australia by a single genus, Tetraponera <tetraponera/tetraponera.htm>. Their elongate, slender bodies and large, oval eyes, combined with their arboreal habits, are distinctive and make these ants easily recognisable.
This subfamily contains three genera and are found world-wide primarily in tropical and subtropical areas, although they extend south into more temperate areas in Australia. There are over 250 described species and subspecies in the subfamily, five of which are known from Australia.
