Paraparatrechina
Paraparatrechina is a genus of small ants in the subfamily Formicinae. The genus contains 39 species distributed in the tropics of Africa, Asia and Australia.
Distribution and habitat
The genus is restricted to the Paleotropics. Thirteen species are known from the Afrotropical and Malagasy regions, and twenty-five species and subspecies from Asia and Australia, although preliminary study suggests that there are many undescribed species. Very little is known about the biology of Paraparatrechina in the Afrotropical and Malagasy regions. They have been found in a wide range of tropical habitats from rainforests to forest clearings in sifted leaf litter, rotten logs, under stones, and from beating vegetation and fogging samples from the forest canopy.Taxonomy
Paraparatrechina was first described as a subgenus of Paratrechina by Donisthorpe. LaPolla et al. elevated the formerly synonymized subgenus to genus rank based on both morphological and molecular data.Description
Paraparatrechina are small formicine ants, which often reflect a metallic iridescence under light microscopy. In darker species, the iridescence tends to be a darker bluish-purple, while lighter colored species either show little iridescence or reflect a more pinkish-purple hue. Paraparatrechina are usually easily distinguishable from other formicine genera by a unique mesosomal setal pattern: two pairs of erect setae on the pronotum, one pair on the mesonotum and one pair on the propodeum. Nylanderia, the genus most likely confused with Paraparatrechina, never possesses a pair of erect setae on the propodeum. The mandibles of Paraparatrechina also possess five teeth, while in Nylanderia six teeth are usually present.Species
