Overview:

A cryptic inhabitant of forest floor leaf litter and rotten wood; from cloud forest of the Sierra Madre de Chiapas. // Distribution

Distribution:

    Americas: Mexico
  Biogeographic regions (According to curated Bioregion/Taxon lists):
    Neotropical

Distribution Notes:

Mexico (Chiapas).

Biology:

This species is known only from the three type workers, all from one Winkler sample of sifted litter and rotten wood from the forest floor. The sample was taken in mesophyll cloud forest in the Sierra Madre de Chiapas, at 1520 m elevation.

Identification:

Face lacking transverse arcuate carina; basal five teeth of mandible acute; apex of labrum bilobed; face and mesosomal dorsum lacking erect setae.

Comments:

This is the largest Central American species. It is very similar to the allopatric O. schusteri, from Volcán Atitlán in Guatemala. The two differ only in the presence of spatulate setae on the face of O. schusteri.

The name refers to the general lack of spatulate setae on the dorsal surfaces.
