Tribe: LonchaeinaeGenus: Lonchaea
SUMMARY
L. albitarsis is a rather large, black, hairy species similar in many respects to L. affinis but with whitish wings. The calyptrae and their fringes are dark
brown. All the tarsi are entirely brownish with paler obscurely yellowish metatarsi. The orbital plate is hairy above the orbital bristle; the eye is bare;
there are several stigmatal hairs on the epimeron, and the notopleuron has a few weak hairs in addition to the two notopleural bristles; the disc of the scutellum
is covered with numerous, erect, fine hairs.
L. albitarsis and L. obscuntarsts are very closely related species but L. albitarsis differs in having several stigmatal hairs (usually one in L. obscuritarsis)
and several hairs behind the sternopleural bristle (bare in L. obscuritarsis). In addition, the shapes of the epandrium, of the surstylus (=inner lamellate process
of Collin) and of the base of the aedeagus differ from those of L. obscuritarsis
