Lintneria lugens (Walker, 1856)

Similar to Lintneria eremitus, but larger. Protarsal first segment longer than in Lintneria eremitus, with 3 or 4 long spines, the apical one more than one-third the length of the segment.Hindtibia as long as 1st and 2nd hindtarsal segments in the female, a little shorter in the male.Abdomen underside pale with small black spots, usually only one distinct in contrast to the otherwise very similar Lintneria geminus, which has one very large spot and several smaller. Forewing upperside blackish grey; discal cell usually with a longitudinal line at the apex; fringe with white dots much smaller than the black spaces between them. Forewing underside with 2 narrow, faint median bands, the space between not darker than the background, so not giving the appearance of a single broad band as is the case in Lintneria geminus. Hindwing upperside with median black bands fusing posteriorly, the distal band projected distad along the veins almost to subdivide the pale band, which is narrower than in Lintneria geminus; fringe almost uniformly white. Uncus abruptly narrowed in the middle, then slightly narrowing to apex, which is quite obtuse, gently bent ventrad, the upperside convex, underside sulcate.Gnathos with an obtusely triangular, flat, mesial lobe that is sinuate and slightly curved dorsad.Valve with subdorsal fold with very long bristles.Harpe non-denticulate, deeply concave on the surface, ventral margin rounded-dilated, distal margin produced at dorsal angle into a prominent hook.Aedeagus produced into a slightly curved semi-cylinder that is round apically, and has a small, sharp tooth subapically. Ostial plate longer than in other species with non-spinose midtibiae, the distal part membranous, transversely folded mesially, the folds mesially connected.Ostium more proximal than in close relative, similarly placed to that in Sphinx leucophaeata.
