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.
