Diagnosis.
Stenentoma sorindeiae
is superficially most similar to
S. bisecta
(see
Razowski and Krüger 2007
: fig. 126), with a dark forewing ground color. The male genitalia of
S. sorindeiae
are most similar to those of
S. chrysolampra
, but in
S. sorindeiae
the top of the tegumen is pointed rather than rounded; the valva is entirely sclerotized and much broader basally; the neck of the valva is very slender and strongly curved; and the very short cucullus is somewhat elliptical.
Description.
Male.
Head
: Vertex and upper portion of frons blackish, lower portion of frons whitish; labial palpus upcurved, white, length ca. 1.2 times horizontal diameter of compound eye.
Thorax
: Notum dark brown, with sparse whitish scales; tegula paler distally. Forewing length
4.1–4.5 mm
(mean = 4.2; n = 4); costal fold absent; forewing slightly expanding distally; costa almost straight in basal 0.65, then gently arched to apex; apex rounded; termen weakly convex, with notch just before middle; ground color dark brown with fine gray lines and distinct refractive bluish lines; orange and yellow-orange spots in postmedian and terminal areas; three faint, white costal strigulae in distal 0.5, separated by blackish divisions; fringe gray, whiter at tornus. Hindwing black-brown, with narrow costal fold in basal 0.6; fringe white with blackish basal line.
Abdomen
: Genitalia (
Fig. 27
) with tegumen long, attenuate to apical prominence at top; pedunculi long, very slender; valva broadest basally, tapering to termination of sacculus; neck short, very slender, strongly curved ventrad; cucullus rounded-triangular, mostly strongly sclerotized, with dense linear row of long spines along caudal edge; phallus long, slender, very weakly sclerotized, about 0.66 as long as valva, with distal 0.2 more narrow, apex flared dorsally, cornuti not evident.
Female.
Head and thorax
: Essentially as described for male; forewing length
3.9–4.5 mm
(mean 4.3; n = 5); hindwing without costal fold, frenulum with three bristles.
Abdomen
: Segment VIII with pair of large, rounded-triangular, lightly sclerotized, lateral regions surrounded by longitudinal wrinkles. Genitalia (
Fig. 37
) with papillae anales unmodified; sterigma ill-defined; ductus bursae long, slender, slightly longer than corpus bursae; ductus seminalis originating postmedially; corpus bursae elongate-ovoid; signa a pair of slender blades, each from a rounded base.
