Lintneria smithi (Taxonomy)
Transferred to Lintneria by Tuttle, 2007, The Hawkmoths of North America: 97.
Most similar in pattern to Lintneria xantus, but structurally more similar to Lintneria lugens.Smaller than both Lintneria xantus and Lintneria lugens; forewing shorter, more rounded apically than in Lintneria xantus; hindwing shorter than in Lintneria xantus. Forewing upperside differs from Lintneria xantus in having the pale area that separates the dark apical line from the dark longitudinal pattern posterior to it on the outer margin smaller; no white double chevron midway along hind margin. The pattern more sharply contrasting than in Lintneria lugens, with a larger proportion of pale areas; the pale marginal area broader near the tornus; the area on the hind margin just distal to the subbasal lines paler and more extensive than in Lintneria lugens; fringe more extensively white. Forewing underside basal area paler than in Lintneria xantus; the postdiscal band whiter and broader. Hindwing upperside with black basal area more extensive than in Lintneria xantus; the postdiscal white band narrower and more sinuate. 34-39 mm. Larger and broader winged than the male. 41-42 mm. Similar to those of Lintneria lugens, but distinguished by:gnathos slightly notched, as in Lintneria lugens, but the sclerotised part of the lateral lobes larger;saccus distinctly narrower, the edges subparallel, not broad with bulging apex;aedeagus with cornute diverticulae of vesica of unequal size, not subequal as they are in Lintneria lugens.
