Boloponera vicans

This species is currently known from a single specimen from a leaf litter (miniWinkler) sample in the Central African Republic near the border of Gabon, Cameroon, and Congo. The collection details (from leaf litter) in combination with morphological characteristics (e.g., lack of eyes) suggests that it is cryptobiotic. The identity of its prey is unknown but its linear mandibles are suggestive of prey specialization.

Worker
Measurements (holotype). TL 3.3, HL 0.79, HW 0.67, CI 85, SL 0.41, SI 62, ML 0.98.

Inner margin of mandible blade with two small, blunt teeth located in basal half of inner margin. Eyes absent. Posterior margin of head slightly concave. Antenna with two-segmented club. Propodeal declivity bordered on each side by raised lamella that does not extend across dorsum. Femoral grove not visible on mesofemur; metafemur with a longitudinal groove present along entire length. Petiole quadrate in profile; subpetiolar process with posterior projecting acute tooth. Abdomen strongly constricted between A3 and A4.

Head, posterior of frontal lobes, densely foveolate punctate; punctures less than one diameter apart and overlaid and separated by reticulate or longitudinal rugae; dorsum of mesosoma with a few shallow punctures, mostly striate. Sides of mesosoma with inconspicuous striae. Propodeal declivity with a few transverse striae but otherwise smooth and highly polished. Petiole with effaced punctures and striae. A3 and A4 with foveolate punctures larger and sparser than on cephalic dorsum; longitudinal rugae present on central dorsum of A3.

Punctures on dorsum of head and mesosoma each with a small suberect hair arising from center, the hair approximately twice the diameter of the puncture. Longer standing hairs present on metanotum, petiole, A3 and A4.
