{Promyopias silvestrii}Santschi's description (1914d, 324, translated by me) is -
WORKER - TL 5 mm; colour red brown; head, mandibles and funiculus darker; legs more clear (translucent?). Shiny, smooth with a fine piligerous puncturation spaced on the body, denser and coarser on the head, which is submatt. Quite abundant short pilosity, especially on the head where it is quite erect. Several long hairs on the mandibles, the clypeus and the posterior gaster.
Head rectangular, slightly longer than wide, occipitum transverse with rounded angles. Sides of head almost straight with the eyes clearly distinct in the anterior sixth; frontal carinae overhanging the clypeus and that forming an anterior rounded small lobe. Frontal notch reaching to the posterior fifth of the head. Mandibles linear, arcuate, as long as the head, truncated and denticulate at the apex, larger in the basal half and narrowing sharply at the mid-point where there is a rudimentray tooth, rest on internal border solely with three minute spaced out denticules. Scape slightly surpassing the posterior quarter. Funiculus with first segment about half as long again as the following segments; segments 3 to 9 narrower than or as wide as long, last five segments slightly swollen. Alitrunk narrower than the head and in profile the dorsum flat and continuous, feebly convex in front. Promesonotal suture very marked, concave posteriorly; no metanotal suture; pronotum a little longer than wide with straight sides, rounded in front. Metanotum laterally impressed at the level of the sutures. Propodeum bordered laterally, dorsum passing into the declivity with a rounded curved. Petiole cuboid, dorsal face trapezoidal and a little longer than the posterior width, slightly higher in front. Anterior face truncated with a smooth border and the posterior face with a rounded angle to the dorsum. Gaster wider than the head, narrowed after the first segment. Lateral spines on the tarsae pectinate, as long as the third of the median spines.
French Guinea, Mamou, 24.viii.1913, 2 workers.
