Diagnosis. This species is superficailly similar to S. hydeana , S. calthograptana , S. umbosana , and S. xenopsana . The presence of a male forewing costal fold and protuberances and specialized scales on the head (visible when longer scales of the vertex are removed) distinguish it from S. hydeana and S. calthograptana , both of which lack these features. Sparganothoides probolosana can be distinguished from S. umbosana and S. xenopsana by the presence of an anterior protuberance, which is absent in the latter two species.

Description. Male. Head: Frons white; vertex roughened, yellowish brown or brownish orange, two exoskeletal protuberances between the mesal-posterior margins of compound eyes; one laterally broad protuberance between antennae; dense clump of small, pale, erect, brownish yellow scales between rear protuberances; broad area of densely packed, short, yellowish brown scales anterior to anterior protuberance. Labial palpus yellowish white to light orange mesally, golden yellow or brownish orange with brown scales laterally. Antennal scaling brownish yellow to brownish orange with scattered brown scales. Thorax: Smooth scaled laterally, golden yellow or brownish orange with light scattering of dark brown scales; dense column of short yellowish white to brown scales mesally; tegula with clump of small, orange, pointed scales at apex giving tegula truncate appearance. Forewing length 10.9–12.0 mm (= 11.3; n = 4). Forewing costal fold short; forewing ground color either predominantly golden yellow or brownish orange with speckling of orange and dark brown scales; pattern elements brown to orange; indistinct subterminal fascia brown and orange; indistinct brown and orange transverse strigulae in interrupted rows in subterminal and terminal areas; dark brown spot at apex of discal cell. Fringe yellowish brown to light orange. Hindwing grayish white with dense gray transverse strigulae throughout, most dense in apical and terminal regions. Abdomen: Genitalia ( Fig. 24 ; slide #JAP2623; EME; Mexico, Durango, 24 mi W La Ciudad; n = 3) with uncus long, slender, widened apically, elbowed at nearly 90° angle at two-thirds distance from base, with long setae dorsally and patch of small setae ventrally; tegumen raised and rounded at base of uncus; socius narrow and rounded posteriorly, secondary arms long, slender, abruptly angled near middle, enlarged apices asymmetrically lobed, moderately boot-shaped; transtilla strongly sclerotized, bilobed, spines small to large, numerous over most of posterior margin, anterior process reinforced with invagination at middle; valva subrectangular with sclerotized crease curved, connecting to near base of sacculus, extending over two-thirds of valva; costa straight; sacculus convexly curved; pulvinus present; phallus pistol-shaped, aedeagus parallel-sided with slight swelling at middle, shorter than phallobase, attenuate at apex, attached to juxta by a narrow process.

Female. Unknown.

Type material. Holotype: Male: MEXICO: DURANGO: 4 mi [6.4 km] S El Salto , 8000’, 10.viii.1986, J. Brown & J. Powell ( EME).

Paratypes (3♂). MEXICO: DURANGO : 4 mi S El Salto , 8000’, 10.viii.1986 (2♂), J. Brown & J. Powell ( EME, NMNH) . 24 mi W La Ciudad , 7500’, 19.vii.1964 (1♂), J. Powell ( EME) .

Immature stages. Unknown.

Distribution. Sparganothoides probolosana is known only from the Sierra Madre Occidental of western Durango, Mexico.

Remarks. This species is dimorphic in color: one form is predominantly golden yellow and the other is brownish orange. The type series includes one golden yellow morph, one brownish orange morph, one intermediate specimen, and one badly worn specimen.

Etymology. The name is derived from the Greek “probolos” (= projecting) and refers to the protuberances of the head.
