Redescription. Adult: Head: ( Fig. 3 ), Vertex and frontoclypeus with grayish-brown scales tipped with pale grayish brown; outer and inner surfaces of labial palpus grayish brown intermixed with grayish brown scales tipped with pale grayish brown and grayish-brown scales along apical margin of second palpomere ( Fig. 3 ); scape of antenna with grayish-brown scales tipped with pale grayish brown, pecten pale yellow, flagellum grayish brown; male first flagellomere unmodified ( Fig. 4 ). Proboscis pale grayish brown.

Thorax: Tegula with grayish-brown scales tipped with pale grayish brown; [mesoscutum with scales missing]. Legs with grayish-brown scales tipped with pale grayish brown intermixed with pale grayish-brown scales near midsegments and apical margins of all segments and tarsomeres. Forewing ( Fig. 1 ), length 6.0− 6.2 mm (n=3), patterned with grayish-brown scales tipped with pale grayish brown intermixed with grayish-brown scales; cell with two spots present or absent; if present, cell with one spot near middle and/or on distal end near tornus. Venation ( Fig. 5 ) with a pterostigma between Sc and R 1; R 3 and R 5 connate basally, divergent slightly beyond half length of R 5; M 1 closer to M 2 from beyond base than to R 5; M 3,CuA 1, and CuA 2 connate; CuA 2 separate from CuA 1, and near right angle from Cubitus. Undersurface brown. Hindwing: translucent pale brown. Venation ( Fig. 6 ) with cubitus appearing 4-branched, with M 2 and basal stem of M 3 and CuA 1 connate from posterior intersection of Cubitus and crossvein of cell; M 2 farther apart from M 1 basally, converging from 1/3 to 1/2 length, parallel distally; M 3 and CuA-1 connate from about 1/2 length from basal stem.

Abdomen: Male with seven irregular rows of spinelike setae on terga 2−7, and three irregular rows of spinelike setae on tergum 8; female with seven irregular rows of spinelike setae on terga 2−6.

Male genitalia: ( Figs. 7−8 ) with uncus setose, widened dorsally, gradually narrowed to an obtuse apex with a keeled edge. Gnathos separated from tegumen by membrane, narrow, entire along ventroposterior margin. Valva divided into an upper part and lower parts; upper part widened basally, gradually narrowed to a broadly rounded apex; densely setose from slightly beyond base to apex; lower part widened basally, slightly narrowed to about 4/5, abruptly constricted, forming a spinelike apical process, acutely curved apically, setose along outer margin of basal 2/3. Vinculum narrowly U-shaped. Juxta platelike, ventral margin nearly straight. Phallus broadly curved, sclerite of phallus wide, bifurcate apically, each bifurcation with acuminate apex; anellus with microsetae.

Female genitalia ( Fig. 11 ): with apical part of ovipositor with 3 membranous subdivisions. Papillae anales, two broadly widened, apically setose lobes. Apophyses posteriores long, about 2X length of apophyses anteriores. Ostium in membrane near emarginate anterior margin of eighth sternum, posterior 1/3 setose. Antrum membranous, short, constricted near inception of ductus seminalis; ductus semilalis slightly anterior seventh segment; ductus bursae short, uncoiled. Corpus bursae elongate with a signum absent.

Remarks. The larva of Syncola crypsimorpha is gray ( Fig. 13 ) compared to the pale yellow color of the larva of S. pulverea ( Fig. 15 ). It appears as numerous as the latter species in regions where surveyed. No gross differences in the pupae of both species were detected ( Figs. 14, 16 ). Descriptions of the immature stages of S. crypsimorpha are forthcoming when specimens become available.
