- Lonchaea Fallen (figs. 48, 49): Lonchaea (3.4-4.2
mm) is a black, heavy-bodied fly with a pointed abdomen and red-brown
eyes. The antennae have three segments with a subapical arista; the
third segment is much more elongate than that of other flies discussed
here. The wing (fig. 48A) is similar to that of Medetera but
has a small cross vein nearer the apical cross vein. The larva (fig.
48B) has soft skin and internal mouthparts.
