Amorbia rectangularis Meyrick, 1931 , Exotic Microlepid. 4:155.

DIAGNOSIS. Amorbia rectangularis is superficially most similar to A. concavana ; A. rectangularis can be distinguished by its scaled frons, narrower costal fold, translucent patch subapically in the HW, the evenly distributed spines on the transtilla, and the presence of minute spines on the vesica of aedeagus.

REDESCRIPTION. MALE. FW length 6.5–8.0 mm (mean = 7.4; n = 10). HEAD: Frons convex, scaled. Vertex rough pale yellow. Antenna with pale yellow scaling. Labial palpus 1.0X length of inter-antennal space, II segment at nearly 90º from III segment, light brown laterally, inner surface paler. THORAX: Dorsum smooth scaled pale yellow; tegula concolorous. FW ground pale yellow with brownish marks in median/postmedian area near costa. Costal fold narrow, reaching 0.25 of costal length. HW with dark apical area wide, bordering a translucent patch. ABDOMEN: Pale yellow. Genitalia as in Fig. 85 (slide # JAP 2972, USNM, Brazil, Nova Teutonia; n = 4). Transtilla rectangular, spines in the middle in two groups. Valva subrectangular. Sacculus sclerotized, 0.75X length of valva, emarginate in basal 0.5, dentate in distal 0.25 along venter. Aedeagus 0.7X length of valva, slender, bent in distal 0.3; vesica with scobination in addition to cornuti.

FEMALE. FW length 9.5–12.0 mm (mean = 9.9; n = 6). HEAD and THORAX: As described for male. ABDOMEN: Genitalia as in Fig. 107 (slide # RL696, USNM, Brazil, Santa Catarina, Nova Teutonia; n = 2). Sterigma developed into small lateral, triangular pockets, slightly rounded anteriorly; median sinus subtriangular. Ductus bursae 2.5 X length of papillae anales, widening towards corpus bursae; sclerotized in posterior 0.33 .

TYPE MATERIAL. Lectotype: Male: “ Brazil, Rio Grande de Sul. Steigelmeyr , August ”. Lectotype designated by Razowski (1964), genit. slide # 4300, J. Razowski ( NHMW) .

DISTRIBUTION AND BIOLOGY. This species was found from southern Brazil to Guatemala (Fig. 136) from 50 to 1670 m elevation. It is apparently multivoltine throughout its range. No data on host plants are available.

IMMATURE STAGES ( Figs. 124, 125). Eggs are dark green, laid in round patches of 30– 62 eggs. Larvae hatched in an average of 11 days (n = 4 clutches) and fed on synthetic diet. Last instars are ca. 2.5 cm in length; the head is tan, with dark brown lateral bands; the prothoracic shield is tan with a wide dark brown band that covers most of the posterior dorsal area of the shield. Development required 7 to 8.5 weeks (JAP 98A19, 99F53).
