Sciopemyia birali Chaves Júnior, Shimabukuro, Pinto & Andrade View in CoL sp. n.

( Figs 15–16 View FIGURE 15 View FIGURE 16 )

Diagnosis. Female: preapical papilla on flagellomere III absent; individual spermathecal ducts practically of the same width throughout their length and eight times or less longer than the spermatheca; this latter with the intermediate rings perceptibly of the same width as the apical rings. Width of individual spermathecal ducts at the spermatheca’s junction equivalent to half or more of the spermatheca’s width, measured at its central part. Width of the basal part of the individual spermathecal ducts (junction with the common duct) ca. half of the spermaheca’s width, measured at its central part. Cibarium with the posterior teeth not lateralized and the distance between the internal ones slightly greater than that between these latter and the external ones. Fifth palpal segment clearly shorter than the sum of 3 rd + 4 th. Individual spermathecal ducts at most 3.5 times longer than the spermatheca. Individual spermathecal ducts ca. two times longer than the spermatheca and increases in caliber as they get closer to the spermatheca. Presence of “callosity” in the individual spermathecal ducts.
