Material examined.

38♂, 16♀ COSTA RICA (34♂, 15♀): The following label data precede individual unique voucher codes of the format yy-SRNP-xxxxxx (SRNP = Santa Rosa National Park, a unique identifier coined when the inventory was confined to Sector Santa Rosa of ACG in the early 1980's) on all reared and light-trapped specimens from ACG (24♂, 9♀): Voucher: D.H. Janzen & W. Hallwachs DB: http://janzen.sas.upenn.edu Area de Conservacion Guanacaste, COSTA RICA.

All records of “on” a given plant species refer definitively to "feeding on." Specimens lacking food plant records were light trapped in the forest and have a 6-digit suffix in their SRNP codes, while reared specimens have a 1-5-digit suffix.

Diagnosis.

The apposition of the forewing and hind wing colors differentiates this species from several unrelated New World species (both tropical and extra-tropical) that share superficially similar orange forewing coloration. None of these has a deep reddish hind wing or the laterally bisected contrast in body coloration between thorax and abdomen. The combination of the expressed M2 on the hind wing, the absence of abdominal coremata, and the configuration of the male and female genitalia are summarized in the generic diagnosis supra vide as distinct from Eriopinae and other pteridivorous Noctuidae .

Description.

Head. Eyes smooth; labial palpi upturned, apex level with antennal base; antennae setose, bifasciculate in males; frons and vertex mix of golden yellow and reddish-orange scales concolorous with those of forewings and thorax.

Thorax. Prothoracic vestiture as described for genus. Wings. Forewing length, males, 12.1 mm– 15.0 mm (males, n = 34, x̄ = 13.5 mm, M = 13.2 mm); females, 12.1 mm– 16.1 mm (n = 17, x̄ = 14.2 mm, M = 14.3 mm). FW not broadly rounded, outer margin convex; FW scaling golden yellow, suffused with reddish-orange scales, some lilacine at costa; postmedial area less heavily suffused with reddish-orange than antemedial or subterminal areas; antemedial, medial, and postmedial lines distinct and unbroken, the medial line ~2 × as thick as others; baso-posterior russet patch; reniform spot constricted to form two white stigmata, the antero-costal stigma round and smaller than the other, j-shaped stigma; HW near-uniformly russet-orange, yellowish-orange terminal line unbroken. FW underside russet in center, bounded by paler shading along the costal and posterior margin below the anal vein; pm line jagged, dark gray, fading gradually from costal fascia to the anal vein. HW underside with discal spot present, pm line visible as a series of dark gray spots where it meets the veins; medial lines of both wings diffuse. Legs. As above, for genus. Scales the same mix of golden orange and reddish as on the head and thorax, but more uniformly reddish on the fore-femora.

Abdomen. As above, for genus. Vestiture paler than on thorax and concolorous with hind wing.

Male genitalia. As above, for genus. Phallus not uniformly sclerotized, weakly so towards the vesica; vesica without cornuti, with a complex of four bubble-like sub-basal diverticula and one larger basal diverticulum; vesica distended baso-medially, recurved clockwise over the phallus before narrowing and everting in a counter-clockwise twist ( Figs 24-27 View Figures 24–27 ).

Female genitalia. As above, for genus.

Immature stages.

Known only from images of living larvae. Larvae are cylindrical, not tapered posteriorly, exhibiting green-brown polymorphism (in some cases the penultimate instar green, ultimate instar brown), and both bear false eyespots on the first abdominal segment; the spot is white postero-ventrally, the front half black with a white dot. In the brown form, the head bears a calico pattern, while in the green form the head is more uniformly green; both forms bear a lateral genal stripe. The brown form is predominantly rusty orange, a pair of subdorsal stripes formed by paler orange wedges. Larvae curl their heads under their abdomens when disturbed, emphasizing their false eyespots. This recall’s Yen and Wu’s (2009) remarks on the eriopine genus Callopistria which "when threatened...bend their abdominal segments A1 and A2 upwards," as do caterpillars in many families. The subdorsal lines in the green larval form comprise a series of irregularly shaped segmental yellow blotches through A6, beneath which runs a series of supra-spiracular spots; a small supra-spiracular black dash may is visible on A4 and A7 as well. The posterior segments, beginning with A7, bear scattered yellow markings.

Biology.

Larvae collected in March, May, June, September, October, and November, with adults eclosing in each of the corresponding subsequent months. Recorded times from the onset of pre-pupa to eclosion 15-17 days. Pupation within a cocoon of leaves lightly silked together. Larvae have been collected feeding on the following ferns: Pteris plumula Desv. (= Pteris quadriaurita Retz., Pteridaceae ), Pteridium caudatum (L.) ( Dennstaedtiaceae ), Thelypteris nicaraguensis (E. Fourn.) C.V. Morton ( Thelypteridaceae ), Salpichlaena volubilis (Kauf.) J. Sm. ( Blechnaceae ), Lomariopsis vestita E. Fourn. ( Lomariopsidaceae ), and Nephrolepis biserrata (Sw.) Schott ( Davailleaceae ). Recorded hymeopteran parasitoids at ACG include Enicospilus maculipennis (Cameron, 1886) ( Ichneumonidae : Ophioninae) and at least one undescribed ichneumonid (cocoon, Fig. 50 View Figures 46–53 ). False eyespots on the first abdominal segment appear well developed by the third instar and conspicuous in the green fourth instar as well as the brown last instars. It may be no more than coincidence that all the brown last instars turned out to be males when reared, while all the green penultimate instars turned out to be females when reared.
