(Figs. 4−6, 11, 14)
Description. Adult (Figs. 4−6): Wing length 11.4−11.6 mm. Head white mixed with gray and brown. Thorax gray mixed with white. Antennae brownish gray, 2/3 length of forewing, each flagellomere with basal row of scales dark brown and apical row gray. Labial palpi with outer side of second segment dark brown, some specimens with white annuli beyond middle and at tip, inner side white; third segment white with two black annuli. Forewing dark gray to brown, subbasal fascia dark brown, with a brown basal patch extending from subbasal fascia to base and from dorsum to near R vein, some specimens with dark brown median spot at base; costa with two dark brown spots, one at 1/3 length and one at 2/3 length, some specimens with a third dark brown spot near base; discal cell with dark brown median streak, some specimens with streak surrounded by brown; apical area with black median streak beyond discal cell and dorsum with dark brown spot at 2/3 length. Hindwing light gray or brown with brown or gray fringe; male with yellow hair pencil at base and narrow line of yellowish orange sex scales from base to CuA2.
Male genitalia (Fig. 11). Uncus squared with apical margin convex, 2x length of gnathos; gnathos stout, spatulate, middle of gnathos broader than base, 0.5 x length of tegumen; valva with costal part slender, longer than tegumen, with bulbous base; saccular part absent; vinculum projecting posteriorly as pair of spatulate processes, sparsely setose on basal 1/3, densely setose on apical 2/3, apices rounded, almost 1/ 3 x length of phallus; phallus 1.5x length of costal part of valva, with a cornutus, fulcrum not developed.
Female genitalia (Fig. 14). Apophyses posteriores 2.5x length of apophyses anteriores; apophyses anteriores 2x length of abdominal segment VIII; sterigma sclerotized, cone-shaped; signum hook-shaped with basal end having lateral flanges.
Diagnosis. S. chambersi can be distinguished from other species of Sinoe by the forewing having a brown basal patch extending from the subbasal fascia to the wing base (Fig. 6), a dark brown median streak in the discal cell, and the male hindwing with a hair pencil at base. The male genitalia differ by having the uncus squared apically, the valva with costal part present and saccular part absent, and the vinculum projecting posteriorly as a pair of spatulate processes. The female genitalia have a cone-shaped sterigma surrounding the ostium bursae (Fig. 14).

Distribution and flight period. This species has a wide distribution extending in the United States from Pennsylvania to Mississippi and also in California and in Canada from Alberta to Quebec with flight times from January to June. The single record from California identified by barcode data and confirmed by dissection of genitalia and may represent an introduction (J.-F. Landry, personal communication.)
Biology. Host data are lacking for this new species, but it differs from S. robiniella by its earlier flight period. Sinoe chambersi is a spring species that flies during late January through March in southern latitudes and March through June in northern latitudes. The early flight periods of S. chambersi before trees have leaves suggest that oviposition occurs in leaf buds or on flowers of its host.
In the northern parts of its distribution in Alberta, Canada, e.g., Lac La Biche and Dunvegan, the species occurs in the boreal zone where plant diversity is limited. Potential hosts among deciduous trees include aspen, poplar, birch, and dogwood as well as Amelanchier and wild rose (J.-F. Landry, personal communication).
Etymology. The specific epithet is a patronym for V.T. Chambers, to recognize his work on Gelechiidae.
