The presence of the metapleural gland, the nodiform (a structure resembling a node, which is a segment found between the mesosoma and gaster, the bulbous posterior portion of the metasoma), the structure of the petiole and its general physical appearance of an ant concludes Sphecomyrma species are ants rather than wasps; the absence of the ...
The structure of the petiole is an easy way to visually classify ants, because the major subfamilies of Formicidae have structural differences: some ants have two-segmented petioles, while others have a single-segmented petiole. [4] [page needed] Certain wasps also possess a two-segmented petiole, notably extant wasps of the family ...
The head capsule bears most of the sensory organs, including the antennae, ocelli, and compound eyes, along with the mouthparts. In the adult insect, the head capsule appears unsegmented, though embryological studies show it to consist of six segments that bear the paired head appendages, including the mouthparts, each pair on a specific ...
The prementum bears a structure called the ligula; this consists of an inner pair of lobes called glossae and a lateral pair called paraglossae. These structures are homologous to the lacinia and galea of maxillae. The labial palps borne on the sides of labium are the counterparts of maxillary palps.

The head and thorax is a dark brown colour while the gaster, legs and antennae are a milky white colour. [3] [2] Due to its small size and light colour, the ghost ant is difficult to see. [4] Ghost ants are monomorphic and the thorax is spineless. [3] The gaster is hairless, and has a back opening that is similar to a slit-like opening. [4]
The ant's colour ranges from brown to black. Described as an arboreal nesting species, O. glaber lives in open or savannah woodland areas, nesting under stones, old dry logs, rotten wood, and in hollow trees and plant stems. Nests can also be constructed in buildings and structures, specifically in pavings, ceilings and walls.
An ant's head contains many sensory organs. Like most insects, ants have compound eyes made from numerous tiny lenses attached together. Ant eyes are good for acute movement detection, but do not offer a high resolution image. They also have three small ocelli (simple eyes) on the top of the head that detect light levels and polarization. [43]
