From the Santschi (1935a) description - TL 2.3 mm.
Comparisons
with canescens
[that seems erroneous].
The head being more completely square. Black; mandibles, scape and
tarsi yellow brown, remainder of appendages brown. Smooth and shiny,
part of metasternum, and posterior part of mesonotum with longitudinal
rugae. Propodeal dorsum part reticulo-punctatate, rest shiny. Pilosity,
fine, long and white, twice as long as canescens, abundant on
whole of body, shorter on the head. Head rectangular, as wide as long,
sides feebly convex, occipitum near straight, occipital angles rounded.
Eyes almost one-third length of face, situated slightly behind the
midline, seen from the front not crossing the lateral borders. Clypeus
carinate, relatively wider. Scape surpassing the occiput by no more
than one-third; funiculus segment 2 longer and more slender than those
following; 2 plus 3 shorter than 1. Pronotum wider than long, largest
around mid-length; meso- and metasternum about same size. Dorsum of
propodeum slightly oblique from the main axis of the thorax but a
little more concave between the angles. Petiole scale truncated and
slightly convex transversely with two divergent denticles; about a
quarter higher than the length of the posterior peduncle. Overall
pilosity and appearance similar to cacozela
but that has a narrow anterior to the head and a thick petiole scale
and a different funiculus formula. A cousin of imperfecta
but that has a much smaller head which also narrows anteriorly, plus
shorter funiculus segments and sparser much shorter pilosity.
