Chapoania dentigera Razowski, 1999

( Figs. 13 , 33 , 45 )

Chapoania dentigera Razowski 1999a: 74 ; Brown 2005: 170; Razowski and Pelz 2010: 7.

Redescription. Head: Vertex and frons with pale gray scales mixed with pale reddish brown scales; length of labial palpus about 4 times diameter of compound eye in both sexes, pale reddish brown scales on outer surface, cream scales on inner surface; antenna in male weakly serrate, with sensory setae ca. 3 times width of flagellomere, antenna in female simple with sensory setae much shorter, sparser.

Thorax: Dorsum and tegula with pale gray scales mixed with pale reddish brown scales; forewing length 8.5‒11.5 mm (n = 5); forewing pattern fairly uniform, but intensity of markings variable, ground color from pale cinnamon brown to pale gray ocherous, slightly paler and tinged with pinkish along costa; finely dotted with brown along termen and at base, with larger spots along costa; brown to purplish brown, hook-shaped, oblique postbasal fascia from costa about 0.3 distance from base to apex, extending to ca. middle of discal cell, oblique postmedial fascia roughly parallel to latter, originating ca. 0.66 distance from base to apex, terminating beyond end of discal cell; faint, semicircular, subapical patch; fringe pale gray brown, cream in dorsal 0.5. Hindwing dingy white, slightly tinged with ocherous, with faint pale gray-brown mottling throughout; fringe pale gray in apical region, cream elsewhere.

Abdomen: Dingy white-scaled throughout. Male genitalia ( Fig. 33 ) with tegumen narrowed dorso-posteriorly, vinculum broadly U-shaped; uncus simple, rod-like, comparatively short, from slightly flattened dorso-posterior margin of tegumen; socius elongate, slender, hairy and scaled; gnathos complex, with lateral prominences and short, pointed terminal plate; transtilla a sclerotized bridge with slender median spine from slightly triangular broadened median portion; valva elongate, costa long, nearly straight, sacculus long, strongly sclerotized, confluent with ventral margin of valva in basal 0.5, ending in a long, free, terminal, strongly toothed process extending across face of valva; juxta with small dorsal process; phallus long, bent at ca. 100˚ angle in distal 0.33, with complex, bilobed, sclerotized tip; vesica lacking cornuti. Female genitalia ( Fig. 45 ) with papillae anales rather slender, ca. 5 times as long as wide, apophyses slender, posteriores ca. 1.5 times as long as anteriores; sterigma complex, a somewhat broad, weakly undulate plate, densely spined throughout, with a small narrow furrow at median anterior margin, and a pair of slender, curved gaps sub-laterally; antrum bulbous, weakly sclerotized, with small hook-shaped process; corpus bursae elongate-ovate, membranous throughout, lacking spiculae and signum.

Molecular characterization. Three specimens were sequenced but only one yielded data—a 407 bp portion of a “barcode” designated as BIN BOLD:AAH7377.

Distribution and biology. Chapoania dentigera is widely distributed in Central Chile from about 30 to 600 m elevation; it is recorded from Cautín, Chiloe, Llanquihue, Ñuble, Osorno, Temuco, and Valdivia provinces. It has also been recorded from Neuquén Province, Argentina, at 875 m elevation. Collection records extend from late November to late February, with a single record from March. The early stages remain unknown.
