Bendib & Minet (1999)
defined the Lithosiini on two characters, one adult, one larval: the forewings
overlap considerably at rest, one concealing most of the distal half of the
other one; the D and SD2 verrucae on larval segments T2 and T3 are arranged
unusually with the D verruca lying caudad or dorso-caudad of the SD2 one instead
of vertically above it. Their discussion of this tribe is still in preparation.
Some additonal features that
may help distinguish the Lithosiini from other tribes include (see also Birket-Smith,
1965): a plesiomorphic, bisignate corpus bursae in the female genitalia;
in the forewing, loss of vein M2 and stalking of M3 with CuA1 (Figs 1c, f, h).
At least one vein from the hindwing cell is usually lost, sometimes several
(e.g. in Lambula Walker, Fig 1e). The forewings tend to be rather long
and narrow, often uniform, sometimes simply fasciated, the fasciae usually
rather diffuse, broad, rather than sharply defined or punctate.
