Material examined: BRAZIL: São Paulo State, São Carlos, UFSCar, Mayaca pond, 2 males with associated pupa and larva exuviae (slide-mounted in Euparal), 13. iv. 2004, C. S. N.

Diagnostic characters. The male lacks blade on the volsella (“ aedeagal complex ” Roback 1985), and the gonostylus is shorter and more sinuate than in other known Ablabesmyia species. In addition A. (S.) metica has lateral tufts of setae on the ninth abdominal segment. The pupa has the aeropyle tube ending apically on the thoracic horn and the apical nipple is evident. It can be separated from other Ablabesmyia species in having shagreen on abdominal tergites consisting of simple spines in arches and thoracic horn with dense, fine, oval-type of reticulation. The larva has palp with three segments, two sclerotized and one membranous. It can be separated from other Ablabesmyia species by having the margin of ligula concave and toothed, by having six apical setae on procercus and a procercus L / W of 3.2 – 3.7.
