Diagnosis.
Argyrotaenia tucumana
can be distinguished from other
Argentine
Argyrotaenia
by the following: a more typical
Argyrotaenia
forewing pattern in the male with a median fascia and a well defined subapical blotch; a slightly shorter valva with a nearly straight costa; the sacculus extending to near the apex of the valva; the vesica of the aedeagus with approximately 14 deciduous cornuti, forming a dense fascicle; the sterigma of the female concave in the middle dorsally, with a weakly sclerotized anterior edge; the cupshaped antrum with distinct microsetae; and the colliculum not broader than ductus bursae.
Description. Male (
Fig. 3
).
Head
: Pale brown. Labial palpus pale brown, speckled with dark brown scales.
Thorax
: Pale brown. Forewing length
5.1–7.1 mm
(mean = 6.0, n = 3), oblong, weakly expanding terminally, costa moderately arched near base, slightly concave subapically, apex obtusepointed, termen rather oblique. Forewing ground color pale tan; basal blotch ill defined, pale brown; median fascia oblique, brown, dark and well defined in costal area, becoming less defined at dorsum; subapical blotch semicircular, dark brown; terminal fascia brownish. Cilia pale brownish. Hindwing pale cream grey, tinged grey in apical 0.3. Cilia pale cream.
Abdomen
: Genitalia (
Fig. 10
) with uncus relatively long, rounded apically; tegumen small; socius small with weak hairs; gnathos arm slender, terminal plate pointed; vinculum with distal fold sclerotized; valva broad, shorter than in
pomililiana
, with costa nearly straight; pulvinus distinct, digitate, with long slender hairs; sacculus simple, long, extending to apex of valva, slightly convex in median part, without free termination; transtilla plateshaped, tapering medially; juxta small. Aedeagus long and slender, with sharp termination, caulis small, coecum penis rounded and developed; vesica with approximately 14 short, lanceolate, deciduous cornuti, forming a dense fascicle.
Female (
Fig. 4
):
Head
: As is male.
Thorax
: Forewing length 8.0 mm (n =1), ground color slightly darker than in male, yellow ochre; basal blotch brownish; median fascia brownish, obsolete in costal area; subapical blotch faint. Hindwing darker than in male.
Abdomen
: Genitalia (
Fig. 15
) with papillae anales large, well developed; apophyses anteriores long; sterigma concave in middle dorsally, with weakly sclerotized anterior edge, anteostial portion weakly sclerotized; antrum large, cupshaped, with distinct microsetae; colliculum not broader than ductus bursae, strengthened with internal sclerite; ductus bursae moderately long; ductus seminalis postmedian and receptaculum seminis developed; proximal sclerite of ductus bursae absent; corpus bursae well developed, spherical; signum typically archipine with internal spine and external capitulum, elongate, length less than 0.5 of corpus bursae.
