Scaralina durango Yanega, sp. nov.

(Figs 17, 30, 45, 60)

Etymology. This species is named for its provenance, and treated as a noun in apposition.

Diagnosis. This species is most similar to aethrinsula, with which it shares the unmodified female tergum 6 that would have excluded it from consideration as a member of the “ Calyptoproctina ”, but with some similarities also to cristata, as the pronotal carina is somewhat stronger than is typical, and the forewings are medially maculated. The face is very dark; the forewings are relatively heavily maculated, especially medially, with some orange tint to the translucent basal area; the hindwing bases are reddish-orange; the emargination of the female anal tube is more nearly semicircular than most species.

Description (female only; male unknown). Head (Figs 30, 45). Many features as in aethrinsula, but lower frons and clypeus much darker.

Thorax (Fig. 45). Many features as in aethrinsula, but pronotal medial ridge more prominent, mesonotum darker laterally; dorsal setae slightly longer.

Wings (Figs 17, 60). Forewings with membrane in several medial cells black and nearly opaque, though not quite as extensive as in cristata, and with somewhat more visible brownish-orange pigmentation to membrane near base; venation much like cristata, if not slightly coarser, generally not as finely anastomosing as in aethrinsula, especially not in the anal portion. Costal crossveins numerous, close, highly anastomosing, highly reticulate, more similar to aethrinsula . Veins and venules often outlined in black, though not quite as often as in cristata . Hindwing bases reddish-orange.

Abdomen (Fig. 17). Nearly identical to aethrinsula, though possibly with weaker medial pigmentation, tergum 6 unmodified.
