Technomyrmex semiruber

Besides the type material, there is a collection from a mature wet forest.

Identification
Bolton (2007) - A member of the T. semiruber complex in the Technomyrmex albipes group. T. semiruber  is very distinctive and is related to the East African species Technomyrmex menozzii and Technomyrmex hostilis, but is easily distinguished from them by its much denser pilosity and presence of erect setae on the scapes and tibiae. See notes under hostilis.

Distribution based on Regional Taxon Lists
Afrotropical Region: Cameroun, Uganda.

Nomenclature

 *  semiruber. Technomyrmex semiruber Emery, 1899e: 489 (w.) CAMEROUN. See also: Bolton, 2007a: 35.

Worker
Bolton (2007) - TL 3.0, HL 0.77, HW (approximate as right side of head is crushed) 0.76, SL 0.74, PW 0.50, WL 1.00. Indices: CI 99,5197,0125, EP167, DTI 134.

Dorsum of head smooth and shining, with abundant setae of varying length (too many to count easily), the longest about equal to the maximum diameter of the eye. Ventral surface of head with numerous short setae. Anterior clypeal margin almost transverse, with only an extremely shallow and feeble concavity across the median portion. Clypeus smooth and shining. Outer margin of eye just touches outline of side in full-face view. Scape, especially leading edge and dorsum, with numerous erect fine setae; most slightly shorter than maximum scape width but the longest about subequal to the scape width. Pranotal dorsum smooth and shining except for setal pits; numerous setae present on pronotum, shorter than the maximum diameter of the eye. Mesonotum in profile with a transverse anterior section and a steep declivitous face, the two surfaces of equal length. Metathoracic spiracle on a strongly prominent tubercle. Propodeum in profile with a long, shallowly convex dorsum that rounds broadly and evenly into the declivity. Propodeal spiracle very high on the declivity. Mesonotum without setae, propodeum with a couple of pairs posteriorly (above the spiracle), but both surfaces appear to have suffered some abrasion. Middle and hind tibiae with short suberect to erect setae that are shorter than the maximum tibial width. Pubescence on legs much denser than on gaster. Gastral tergites 1 - 4 each with abundant setae, the longest subequal to the maximum diameter of the eye. Gastral tergites strongly shining; gastral pubescence short and very sparse. Head, mesosoma, petiole, gaster and appendages glossy light brown; gaster glossy dark brown.

Type Material
