Sinoe Chambers

Sinoe Chambers, 1873b: 229 , 231.

Type species: Sinoe fuscopalidella Chambers, 1873 , by monotypy.

Description. Imago ( Fig. 56 ). Labial palpus with third segment as long as second. Clypeus with ventral margin broadly truncate or rounded. Antenna longer than half forewing length. Ocellus absent. Posterior area of sitophore with four campaniform sensilla not in trapezoid; anterior area with two or four campaniform sensilla. Forewing (length/width ratio 4.6) with pterostigma; R5 and M1 stalked, M2 and M3 connate, CuA1 and CuA2 present ( Fig. 7 ); subbasal fascia directed from apex of costa toward dorsum; median fascia transverse or directed from base of costa toward posterior margin. Hindwing (length/width ratio 5.4) with R5 and M1 connate, M2 and M3 connate, M3 and CuA1 connate ( Fig. 16 ).

Male genitalia ( Fig. 29 ): uncus rounded apically, subequal in length with gnathos; gnathos without dorsal part, ventral part of gnathos hook shaped; valva divided into costal and saccular parts; tegumen basal width/ length 0.4; phallus without cornuti, phallic fulcrum well developed.

Female genitalia ( Fig. 47 ): apophyses posteriores 1.5 x length of apophyses anteriores; apophyses anteriores 2 x length of abdominal segment VIII; sternum surrounding ostium bursae sclerotized; ductus bursae smooth; signum present.

Larva. Undescribed.

Pupa. Undescribed.

Diagnosis. Sinoe species are superficially similar to Coleotechnites , but can be differentiated by having the forewing with the subbasal fascia directed from apex of costa toward posterior margin, and by the bilaterally symmetrical vinculum + valva and apically hook shaped ventral gnathos instead of a cushionlike apex in male genitalia.

Hosts. Fabaceae : Amorpha fruticosa L. ( S. robiniella ), Robinia pseudoacacia L. ( S. robiniella ). ( Forbes 1923; Godfrey et al. 1987; Robinson et al. 2002; Schaffner 1959).

Diversity and distribution. This genus includes one species occurring in eastern North America ( Hodges 1965).
