Diagnosis.
Gypsonoma scolopiae
is most similar to
G. o p s o n o m a
(Meyrick, 1918) and
G. scenica
(Meyrick, 1911)
from
South Africa
, but
G. scolopiae
has more slender socii, broader valvae, an atrophied horn of the distal edge of basal cavity, and a smaller spiny part of the cucullus. The female genitalia are distinguished by a large, sclerotized, somewhat angulate J-shaped cingulum and a strongly reduced sterigma.
Description.
Male.
Head
: Scaling on vertex mostly pale gray brown, frons and median part of vertex cream white; labial palpus pale gray brown on outer surface, white on inner surface, segment III and distal portion of segment II white, length ca. 1.2 times horizontal diameter of compound eye.
Thorax
: Notum whitish gray, brown anteriorly. Legs unmodified. Forewing length
4.5–5.5 mm
(mean = 5.1; n = 5); forewing weakly expanding distally; costa straight; termen moderately oblique to costa, straight, with weak concavity below apex; ground color white with ill-defined gray and pale brown suffusions, basal patch (basal 0.4) dark gray to brown with irregular striations and spots of gray and white, outer margin of patch convex, well defined by darker scales, postmedian interfascial regions white with some grayish suffusions, an oblique median fascia from costa ca. 0.6 distance from base, narrow at costa between strigulae 4 and 5, interrupted at upper and lower margins of discal cell to form an oblique line with a broad triangular spot on dorsum; costal strigulae white, divisions brownish gray; speculum faint, grayish with two or three small black dots; dark rhomboid blotch from speculum to concolorous apical blotch; termen finely edged with brown; fringe dark gray, whiter at tornus. Hindwing gray cream, paler basally; fringe concolorous with middle of wing.
Abdomen
: Genitalia (
Fig. 22
) with posterior edge of tegumen bilobed (possibly representing uncus); socius moderately sclerotized, rather slender, rounded distally; base of gnathos well sclerotized; valva broad, rounded distally; cucullus distinct with semicircular area of dense spines, large semi-membranous area of valva distad of cluster of spines; phallus ca. 0.6 length of valva; vesica with 8–12 long, slender cornuti that are weakly undulate subapically.
Female.
Head and thorax
: Essentially as described for male, except forewing length 4.8–6.0 mm (mean = 5.4, n = 5); forewing often slightly paler than in male, with narrow darker posterior edges and darker subtornal blotch; frenulum with two bristles.
Abdomen
: Genitalia (
Fig. 34
) with papillae anales slender; apophyses posteriores ca. 2 times as long as apophyses anteriores; sterigma membranous with strongly sclerotized, short, tubular antrum separated from long, strongly sclerotized, somewhat angulate J-shaped cingulum by short membranous region of ductus bursae; ductus seminalis from near anterior end of cingulum; two long, bladelike signa, equal in size.
