Pachylioides resumens (Walker, 1856)

Abdominal tergites with a black basal belt; the belts of the anterior segments visible, at least laterally, in specimens where the segments are telescoped into one another.Spines of posterior tergites much shorter, weaker, more numerous, closely spaced. Penultimate flagellomere of antenna longer than vertically broad. Spines of proximal sternites contiguous, those of posterior sternites separate, stronger sclerotized spines generally alternating with weaker ones.Palps closely appressed to head, rounded in lateral and dorsal views, not projecting.Hind edge of merum of midcoxa and hindcoxa carinate, very faintly angulate. Outer spur of midtibia only one-quarter shorter than inner. Forecoxal hair-brush strongly developed.Scales along upper and lower edges of hindtibia and hindbasitarsus prolonged; hindtarsus with some spines between the four regular rows, hindbasitarsus slightly less than half the length of the tibia. Uncus with two long processes, which are broadest apically, downcurved and somewhat twisted, the flat side being nearly vertical.Gnathos processes as long as those of the uncus, the left a little shorter than the right, both somewhat compressed and slightly S-shaped, apex not very acute.Anal tube projecting between the lobes of the segment in lateral view.Valve sole-shaped, broader and shorter than in Erinnyis, with a patch of stiff bristles on the inner surface in the middle of the dorsal margin; a double basal tubercle, smooth, the lower one carinate.Harpe produced ventrally into a strongly hooked, short process that is plainly visible from the outside.Aedeagus with an obtuse straight apical process that bears a row of setae along the left edge, proximally the row generally double. Sternite 7 long, trapezoidal, apex membranous.Tergite 8 rounded-sinuate, the lobes strongly rounded.Sterigma rather large, apical edge membranous, a deep semilunar proximal cavity, surrounded proximally by a small ridge.Ostium bursae postmedian, small, covered by a heart-shaped bilobed flap.
