Oligomyrmex (Aeromyrma) urichi (Wheeler)

Type location Trinidad (Spelaeomyrmex urichi new species, Wheeler, 1922c: 9, illustrated, worker; in Erebomyrma by Wilson, 1962a: 63; in Oligomyrmex, Ettershank, 1966: 124; reverted to Erebomyrma by Wilson, 1986b: 61; "revived combination" in Bolton, 1995: 299) Guacharo Cave, F M Urich; major, minor and queen described.

It seems from Longino (http://academic.evergreen.edu/projects/ants/genera/carebara/home.html) that this is synonymous with nevermanni; confirmed by Fernández (2004).

Placed in the Carebara concinna species somplex by Fernández (2004),  This bears a striking similarity to the African saxicola species-group, especially the relatively small Pheidole philippi, the obvious difference being the Pheidole have 12-segmented antennae and large eyes on the minor.

The Ants of Costa Rica website (John Longino) has:

Range: Mexico to southern Brazil (Fernández 2004). Costa Rica: wet forest habitats on both slopes to 1300m elevation.

Identification: Antennae 11-segmented; pronotal dorsum longitudinally rugose; hind tibia with long suberect pilosity.

Similar species: brevipilosa.

Natural History: This species is mainly known from Winkler samples of sifted litter from the forest floor. It is relatively common in Winkler samples from lowland and mid-elevation wet forest habitats. It is less often collected using other methods. Nichole Barger made one collection of urichi while baiting at La Selva Biological Station. Bill Eberhard observed a flight of males from a nest in the ground near his home in Cerros de Escazu. Nevermann found the type series of nevermanni (now a junior synonym of urichi) in a rotten log, in company with Pachycondyla stigma.
