Glauce Chambers

Glauce Chambers, 1875a: 11 .

Type species: Glauce pectenalaeella Chambers, 1875 , by monotypy.

Description. Imago ( Fig. 53 ). Labial palpus with third segment nearly as long as second, apex acute. Antenna more than half forewing length. Clypeus with ventral margin rounded. Ocellus present. Posterior area of sitophore with four campaniform sensilla in line except one sensillum offset on left or right side; anterior area with six campaniform sensilla. Forewing (length/width ratio 4.4) without tufts of raised scales; R4 and R5 stalked, R5, M1, and M2 separate, M2 and M3 connate, CuA1 and CuA2 present; median fascia transverse or directed from base of costa toward posterior margin. Hindwing (length/width ratio 4.8) with strong black hair pencil at one–third length of costa in males; R5 and M1 widely separate, M2 twice as near to M3 as to M1, M2 and M3 separate, M3 and CuA1 separate. Male abdominal tergum VIII lingulate.

Male genitalia ( Fig. 26 ): uncus present, subequal in length with gnathos; gnathos divided into dorsal and ventral parts; valva entire, not divided into costal and saccular parts; tegumen basal width/length ratio 0.8; saccus well developed; phallus without cornuti; phallic fulcrum well developed.

Female genitalia ( Fig. 44 ): apophyses posteriores about 3 x length of apophyses anteriores; apophyses anteriores subequal in length with abdominal segment VIII; antrum undeveloped or membranous; accessory bursae lacking spinules; ductus bursae lacking colliculum; signum pocketlike.

Larva. Undescribed.

Pupa. Undescribed.

Diagnosis. Glauce and Agnippe differ from other genera of Teleiodini by lacking tufts of raised scales on the forewing. Glauce is easily distinguished from Agnippe by having an undivided male valva and vein M1 separate from R 5 in the forewing.

Hosts. Unknown.

Diversity and distribution. Glauce includes one species in eastern United States.

Notes. An undescribed species of Glauce has been misidentified in many collections as the type species, G. pectenalaeella . Chambers described the male of G. pectenalaeella from Texas as having a hindwing with the costal margin having a row of widened “bristles” that changed gradually into large scales from the base to the middle. Male specimens matching this description have been collected in longleaf pine savannahs in Louisiana and remnants of the Black Belt prairie in Mississippi. These specimens have sex scales that vary from black near the wing base to gray near midwing. In contrast, the undescribed species, sp. 1 in Appendix 1 and elsewhere, has a black, hair pencil near the base of the costa that extends no more than one third the wing length. The undescribed species occurs widely in a variety of habitats in eastern North America.
