Holotype.
female, pinned, with genitalia slide no. AD967. Labels: Argentina, Misiones Province, Puerto Iguazú, 25°41'8"S, 54°26'47"W, elevation 160 m, mining larva on Allophylus edulis (A. St.-Hil., A. Juss. & Cambess.) Hieron. ex Niederl., Sapindaceae , 10 Feb 2019, field card no. 5291, A. Diškus (ZIN).
Diagnosis.
Externally, this new species can be differentiated from all congeneric species by the distinct forewing pattern with an ochre, oblique, postmedian fascia and ochre subapical spot (Fig. 47 View Figures 44–49 ). Male unknown. In the female genitalia, the new species is characterized by the unique, oval-shaped widening of slender part of corpus bursae proximally (Fig. 111 View Figures 111–115 ). This species is also distinctive because no other species in Tischeriidae is known to feed on Allophylus edulis (A. St.-Hil., A. Juss. & Cambess.) Hieron. ex Niederl. ( Sapindaceae ).
Description.
Male. Unknown.
Female (Fig. 47 View Figures 44–49 ). Forewing length 3.2 mm; wingspan 6.9 mm (n = 1). Head: frons and pecten ochre cream to pale ochre; golden cream; collar glossy ochre-grey; antenna slightly longer than one half the length of forewing; flagellum dark grey on upper side, pale grey on underside. Tegula and thorax glossy ochre-grey. Forewing slender, glossy grey-ochre in basal half, with bright ochre, oblique postmedian fascia and bright ochre subapical spot widely surrounded by black and cream-tipped scales with purple iridescence; fringe black-grey, without fringe line. Hindwing and fringe grey on upper side and underside, without androconia. Legs grey to blackish grey on upper side, ochre cream on underside. Abdomen blackish grey on upper side, glossy pale ochre with some grey scales (especially prominent proximally) on underside; anal tufts absent; ovipositor slightly protruding.
Female genitalia (Figs 111-115 View Figures 111–115 ) 1310 µm long. Ovipositor lobes large, rounded, clothed with short, modified peg-like setae; area between ovipositor lobes slender, with tiny papillae and some short setae. Second pair of lobes, lateral and anterior to the ovipositor lobes, slightly smaller, triangular, with long slender setae. Posterior apophyses slightly shorter than anterior ones (Fig. 115 View Figures 111–115 ); prela comprised of three pairs of rod-like projections (Fig. 115 View Figures 111–115 ); inner pair of these rod-like projections very long (as long as anterior apophyses). Corpus bursae folded, oval-shaped proximally, bulbous distally (Fig. 111 View Figures 111–115 ), without pectination or signum on wide, basal part, but with some tiny spines proximally (Fig. 113 View Figures 111–115 ). Ductus spermathaecae very slender, with many coils (Fig. 112 View Figures 111–115 ).
Bionomics.
(Figs 19-21 View Figures 15–21 ). Host plant is Allophylus edulis (A. St.-Hil., A. Juss. & Cambess.) Hieron. ex Niederl., Sapindaceae (Fig. 19 View Figures 15–21 ). Larvae mine leaves in February. Larva very pale green with a bright green intestine and very pale brown head. The mine is blotch-like (Figs 20 View Figures 15–21 , 21 View Figures 15–21 ), fully transparent, without frass. Adults occur in March.
Distribution.
This species is known from a single locality in northern Argentina, Misiones Province, Puerto Iguazú, at the elevation ca. 160 m, but the host plant has a much wider distribution (see Discussion).
Etymology.
The species name is derived from Latin fasciatus (banded, with a fascia) with the prefix supra, in reference to the unusual (in Tischeriidae ), forewing pattern with a distinctive postmedian facia.
