Technomyrmex sycorax casent0103273 dorsal 1.jpg Paratype Specimen Label

Workers from Gabon were collected from leaf litter and sweeping from low vegetation (Bolton 2007).

Identification

Bolton (2007) - A member of the Technomyrmex textor group. Essentially sycorax is a slightly larger and more elongated close relative of Technomyrmex parviflavus. The former also has longer scapes and smaller eyes, has the propodeal dorsum longer with respect to the declivity, and has body colours that strongly contrast between mesosoma and gaster.

Description

Worker

Holotype. TL 3.0, HL 0.64, HW 0.54, SL 0.74, PW 0.39, WL 0.98. Indices: CI 84, SI 137, OI 30, EPI 164.

Answering the description of parviflavus but differing as follows. Scape relatively longer, eyes slightly smaller, promesonotum more slender (compare indices). Propodeum in profile with a dorsal straight-line length that is distinctly greater than the depth of the declivity to the spiracle. Head, mesosoma, petiole and legs yellow but gaster black, the colours strongly contrasting. Sculpture of dorsal head more strongly developed, consisting of sharply defined minute reticulate-punctulation.

Paratypes. TL 2.7 - 3.0, HL 0.60 0.64, HW 0.50 - 0.52, SL 0.67 0.70, PW 0.37, WL 0.86 0.98 (2 measured). Indices: C1 81 - 83, SI 134 - 135, or 28 - 31, EPI 73 - 74, DTI 162 - 170. As holotype.
