Gonionota hemiglypta

Alar expanse 17–21 mm.

Labial palpus ferruginous; second segment fuscous dorsally and apically; third segment fuscous at middle with carmine scales at base and preapically; apex yellowish. Antennal ferruginous basally, shading to brown toward apex; segments each with tiny fuscous spot. Head yellow with ferruginous, carmine-tipped spreading scales laterally. Thorax yellow mixed with carmine; tegula ferruginous, tipped with yellow and carmine. Forewing ground color yellow with dorsal half strongly overlaid carmine; costal half ferruginous at base, this color becoming attenuated toward apex; extreme costal edge narrowly whitish; at basal third, in cell, a small black dot followed at end of cell by a similar dot; termen and cilia, from vein 7 to tornus, ferruginous. Hindwing ochraceous tawny; cilia yellowish white with ochraceous tawny suffusion. Foreleg ocherous white; femur overlaid ferruginous on outer side; tibia carmine shaded; midleg ocherous white; hindleg ocherous white with small ill-defined fuscous spot at middle and another near distal end of tibia. Abdomen grayish dorsoanteriorly, ferruginous posterodorsally; ocherous white ventrally, sparsely irrorate with black laterally.

Male genitalia slide JFGC 10820. Harpe narrowest at base, dilated at middle, terminating in a broadly rounded cucullus; from inside middle of costa, a conspicuous cluster of fine setae; clasper short, terminating in ventrally directed spines; from basal third a stout curved spine; sacculus with small flap at middle. Gnathos an oval spined knob. Uncus broad basally with widely separated curved lateral arms. Vinculum a narrow band. Tegumen about as long as broad. Anellus an elongate plate with deep excavation on each side and terminating in a pair of widely divergent slender spines. Aedeagus moderately slender, curved, pointed.

Female genitalia slide JFGC 10821. Ostium broad, transverse, oval, with crenulate ventral edge. Genital plate a narrow sclerotized band. Antrum sclerotized. Inception of ductus seminalis at anterior edge of antrum. Ductus bursae membranous. Bursa copulatrix membranous. Signum a small, quadrate, dentate plate.

HOLOTYPE.—USNM 71092.

TYPE LOCALITY.—Brazil, Nova Teutonia.

DISTRIBUTION.—Brazil.

Described from the holotype and one paratype (IV. ’48, Fritz Plaumann).

This species is similar to G. vivida (Meyrick) from Bolivia but can be distinguished easily by the widely separated arms of the uncus. In vivida the uncus arises as a broadly based stalk, divided apically as in many other members of Gonionota.

Gonionota hemiglypta is a moth in the family Depressariidae. It was described by John Frederick Gates Clarke in 1971. It is found in Santa Catarina, Brazil.

The wingspan is 17–21 mm. The forewings are yellow with the dorsal half strongly overlaid carmine. The costal half is ferruginous at the base, this color becoming attenuated toward the apex. The extreme costal edge is narrowly whitish and at the basal third, in the cell, is a small black dot followed at the end of the cell by a similar dot. The hindwings are ocheraceous tawny.
