Diagnosis. Rejectaria villavicenciamay be the largest named species of New World Herminiinae. Both villavicenciaand villosaare sexually dimorphic, but villavicencialess pronouncedly; the paler tannish-brown coloration in the median field of the female FW is more diffuse in villavicenciathan in villosa. Male villavicenciaare slightly larger than male villosawith more elongate forewings, but the am and pm lines are wavy in both sexes of villavicencia, whereas the pm line in villosais straight. The reniform spot in villavicenciais light brown, larger than that in villosa, and, in the male of villavicencia, more clearly divided and circumscribed with a black boundary. The am and st lines in villavicenciaare discontinuous and less faint than in villosa, and the terminal line is a series of alternating black and orange-brown curved dashes; all lines reappear in the same configuration on the middle third of the HW, as in villosa.The male genitalia of villavicenciaare distinct, with the costal sclerotization terminating less than midway along the costa as a thorn-like projection. The female genitalia, again most similar to those of villosa, share with that species a laterally produced deformation above the whorled appendix bursa; both share with magasand ritaashleyaethe distinct band of signa but the number of serrate hemi-discs differs. Re-description. Head. ( Figs 33–34, 41) Frons, vertex gray-brown; antennae setose-ciliate; male palpi ( Fig. 33) sweeping over head, with eye-level notch at the acutely angled junction of 1st and 2nd segment; 2 ndsegment broad at base and tapering as it arches over head; 3 rdsegment approximately as long as 2 nd; female palpi ( Fig. 34) incomplete on specimens examined but 2 ndsegment arches gently upward. Thorax. Wings—(males, 30mm, n=5; female, 30mm, n=1[ type]) Sexual dimorphism conspicuous, with paler tannish-brown coloration dominant but diffuse in median field of female FW; reniform spot tannish-orange, outlined in black; bands and coloration continue on hind wings. Legs—( Figs 33–34, 41) Male forefemoral tufts massive; legs more or less uniformly tannish-gray throughout; bands faint, if present. Abdomen. Gray-brown above, concolorous with ground color of uppersides of wings. Male genitalia. ( Figs 49–50, 61–64) Uncus elongate, setose, sheepsfoot-shaped; costa rudimentary, sclerotized in basal ~third only, free terminus reduced to a small nub mid-way along the costa, bearing a small setal tuft; vinculum bluntly tapered; small phallic ridge present; vesica multi-lobate; microspines distributed on phallus at base of vesica, concentrated on subbasal lobe and more diffusely throughout lower vesica; localized sclerotization apically. Female genitalia. ( Fig. 88, 96) Ductus bursae elongate with sclerotized bands along most of its length; corpus bursae deformed where it meets ductus, at base of whorled appendix bursae comparable to that of villosaand ritaashleyae; well-developed mid-ventral band of micro-spinules ( Fig. 96) on corpus bursae, subparallel to long axis of corpus, punctuated by a series of 14 internal perpendicular ridges comparable to those in villosa, richardashleyi, ritaashleyae, and magas; secondary band of spinules present near junction with ductus bursae. Immature stages. ( Figs 105, 107) Mature larvae purplish with reddish intersegmental rings; head and prothoracic shield dark brown; spiracles dark, conspicuous.
Etymology.The specific epithet villavicenciarefers to the typelocality, Villavicencio, Colombia.
Biology.Larvae have been documented feeding on Cyclanthus bipartitus(5) and Asplundia utilis(1).
Distribution. Colombia, Costa Rica
Remarks.This and the closely related villosaare the two largest species of New World Herminiinae of which we are aware. We acknowledge the possibility that the reared specimens of villavicenciafrom Costa Ricarepresent a distinct species from the Colombia holotype, but without the benefit of examining and multiple barcoded specimens, there is no evidence to support the description of a second species. Hence we treat the Costa Rican material as villavicenciapending the accumulation of more data.
