Stegomyrmex connectens

This species is known from a single queen and a tentatively, and questionably, associated male.

Identification
Feitosa et al. (2008) - The gyne of S. connectens can be immediately recognized and separated from the other species in the genus by the presence of two anteroventral projections in the petiolar peduncle.

Distribution based on Regional Taxon Lists
Neotropical Region: Bolivia, Ecuador, Peru.

Nomenclature

 *  connectens. Stegomyrmex connectens Emery, 1912b: 100, fig. 5 (q.m.) PERU. See also: Hölldobler & Wilson, 1986a: 16; Diniz, 1990: 284; Feitosa, Brandão & Diniz, 2008: 79.

Feitosa et al. (2008) - Stegomyrmex connectens  is the type species of the genus and remains known only by a single gyne collected in Vilcanota, Peru, and a male tentatively assigned to this species, from Mapiri, Bolivia. In the original description, Emery (1912) mentioned that the male might belong to a different Stegomyrmex  species, although he decided to describe it as S. connectens . Diniz (1990) examined this specimen and noticed that it presents some important morphological differences in comparison to the conspecific gyne, mainly in wing venation, pilosity, and by the absence of a second anteroventral spine in the petiolar peduncle. These differences, and the disjunct distribution of the gyne and male specimens, may indicate that they indeed do not belong to the same species.

Type Material
