| Microdaceton viriosum|
Specimens have been collected in litter-samples from wet forest.
Bolton (2000) - In the type-series the first gastral tergite and sternite are both superficially sculptured in at least their basal halves; the propodeal spines are stout, straight to slightly downcurved. With the head in profile the highest point of the vertex has a pair of small, low, obtuse tubercles. Another, smaller, tubercle is present anterior to this pair, the three together forming the points of a triangle.
