Diagnosis. Sparganothoides cornutana is superficially similar to S. canorisana and S. capitiornata , but the apices of the socius/gnathos arms are not lobed in S. cornutana . Sparganothoides cornutana appears to be most closely related to S. broccusana , but in S. cornutana the apex of the socius/gnathos arm is parallel-sided as in S. aciculana .

Description. Male. Head: Frons yellowish white, smooth scaled; vertex roughened, yellowish white or brownish yellow to golden yellow; two exoskeletal protuberances between mesal-posterior margins of compound eyes; dense clump of small white to yellowish white scales between protuberances, extending mesally along vertex between eyes and antennae. Labial palpus white mesally, yellowish white to brownish yellow laterally. Antennal scaling yellowish white to brownish yellow, often with dark brown scales. Thorax: Smooth scaled laterally, brownish yellow or golden yellow; dense column of short white to yellowish white scales mesally; tegula with clump of small orange or brown pointed scales at apex giving tegula truncate appearance. Forewing length 6.9–8.4 mm (= 7.6; n = 10). Forewing costal fold extending less than one-half wing length; forewing ground color yellowish white to brownish yellow or golden yellow with scattered orange and brown scaling; pretornal patch brown with some orange scales, often angled toward apex from discal cell; often with ill-defined brown subterminal fascia accented by extension of tornal patch; indistinct orange and brown transverse strigulae throughout subterminal and terminal areas; often with suffused grayish brown spot at distal end of discal cell. Fringe yellowish white to brownish yellow to golden yellow. Hindwing white to light grayish white, becoming yellowish gray or gray toward margins, with ill-defined gray transverse striae throughout in most specimens; patch of yellowish white to orange scales at anal angle. Abdomen: Genitalia ( Fig. 38 View FIGURES 37–38 ; slide #JAP3245; NMNH; Mexico, Chiapas, San Cristóbal de Las Casas; n = 10) with uncus long, slender, slightly tapered, gently curved, with very sparse long setae dorsally and patch of short setae ventrally; tegumen moderately raised and triangular or ovate at base of uncus; socius/gnathos broadly rounded posteriorly, secondary arms approximately equal in length to apical portion, slender, abruptly curved just before apical portion, apical portion parallel-sided, long, narrow; transtilla sclerotized, straight, spines short with some scattered larger spines, numerous over most of posterior margin, anterior margin without reinforcement; valva unusually shaped, without a sclerotized crease near middle, costa straight to gently curved, sacculus angular, narrow, rounded basally, thick and flattened distally beyond elbow to apex, extending slightly beyond apex of valva, pulvinus reduced; phallus pistol-shaped, aedeagus parallel-sided, slightly curved, subequal to length of phallobase, attenuate apically, attached to juxta by a short process; cornuti with a minute spine near base.

Female. Head, Thorax: Essentially as described for male except lacking costal fold, slightly larger, and with a less defined pretornal patch. Forewing length 6.8–9.9 mm (= 8.2; n = 7). Lacking yellowish white to orange scales at anal angle of hindwing. Abdomen: Genitalia ( Fig. 60 View FIGURES 57–60 ; slide #RL679; NMNH; Guatemala, Volcán Santa María; n = 7) with ovipositor complex large; papillae anales parallel-sided, subtriangular posteriorly; sterigma narrow, sclerotized, curved; ductus bursae relatively short, widened anteriorly; corpus bursae small relative to ovipositor complex posterior to ductus bursae, irregularly rounded; signum simple, shorter than most congeners, approximately two to three times as long as wide, weakly curved, rounded at apices.

Purulha , vii.[no year] (1♀), Schaus and Barnes Collection ( NMNH) . Volcán Santa María , vii.[no year] (1♂, 2♀), xi.[no year] (5♂, 1♀), Schaus and Barnes Collection ( EME, NMNH) .

Immature stages. Eggs are dark peach-orange, laid in patches of 5–18 (= 10.0 eggs per patch, n = 4). Eggs hatched in 10 days. Larvae fed on synthetic diet and Quercus lobata but refused Prunus lyonii . The anal comb has seven tines. Development from oviposition to pupation required 34–48 days. Adults emerged in 11–18 days following pupation.

Biology. Adults have been recorded in mixed broadleaf woods in July, August, and November, suggesting that this species is bivoltine.

Distribution. Sparganothoides cornutana is recored from Hidalgo, Veracruz, and Chiapas, Mexico, south into Guatemala.

Etymology. The name cornutana , which was proposed by Lambert (1950), is derived from the Latin “cornu” (= horn) and refers to the protuberances on the head.
