( Figs. 1–6 View FIGURES 1–6 , 19–22 View FIGURES 19–24 , 30–34 View FIGURES 30–34 , 49, 50 View FIGURES 47–52 )

Type material. Holotype: ♂, Peru, Urubamba Province , near Machu Picchu, 13°9’48”S, 72°32’12”W, elevation ca. 2180 m, from feeding larvae 19.x.2008, ex pupa xi.2008, field card no. 4944, leg. A. Diškus, genitalia slide no. AD1050 ( ZIN) GoogleMaps   . Paratypes 4 ♂, 2 ♀, same label data as holotype, genitalia slide nos. AD1048 GoogleMaps   ♂, AD1049 ♀, AD1051 ♀ ( ZIN)   ; 1 ♂, same label data, genitalia slide no. AD1047 ♂ (from adult in pupal exuvia) ( NRC)   .

Diagnosis. Only the male genitalia provide reliable diagnostics: the combination of a unique-shaped uncus (see Figs. 30, 32 View FIGURES 30–34 ), and abruptly bent dorsal lobe of the valva ( Fig. 30 View FIGURES 30–34 ) with distal spine-like process ( Fig. 34 View FIGURES 30–34 ) distinguishes A. mystica   sp. nov. from all other Astrotischeria species.  

Male ( Figs. 19–21 View FIGURES 19–24 ). Forewing length 4.1–4.5 mm; wingspan 9.0– 9.8 mm (n = 5).

Head. Frons, palpi, and pectens pale ochre yellow to bright ochre, occasionally ochreous cream; frontal tuft and collar comprised of brownish grey, pale-tipped lamellar scales; antenna slightly longer than one half the length of forewing; flagellum dark brown, annulated with ochre cream; sensilla relatively short, very fine, inconspicuous.

Thorax. Tegula and thorax densely covered with grey-brown, ochre-tipped scales or entirely dark grey-brown. Forewing densely speckled with grey-brown and dark grey-brown scales and small, irregular spots of bright yellowish ochre scales; fringe dark grey, apically brown-ochre; fringe line absent or incomplete, comprised of dark brown or black-brown scales; forewing underside dark grey-brown, without spots or androconia. Hindwing dark brown to grey-brown on upper side and underside, without androconia; fringe brown to grey. Legs grey-brown to dark grey-brown.

Abdomen. Brownish grey on upper side and underside, ochre glossy distally on underside; anal tufts dorsal, long, dark grey; genital plates brownish grey. Genitalia ( Figs. 30–34 View FIGURES 30–34 ) with capsule 420–455 µm long (or 585 µm long if measured from valval tips to vinculum), 260 µm wide. Uncus ( Figs. 30, 32 View FIGURES 30–34 ) comprised of two sets of short but wide lobes. Valva ( Figs. 30, 31 View FIGURES 30–34 ) about 420 µm long (excluding the basal process); dorsal lobe wide and with spine-like processes distally (see Fig. 34 View FIGURES 30–34 ). Anellus only slightly thickened, mostly membranous, inconspicuous. Vinculum rounded ( Figs. 30, 31 View FIGURES 30–34 ). Phallus 360 µm long, deeply bifurcated, symmetrical, with a large spine on each apical lobe ( Figs. 30, 33 View FIGURES 30–34 ).

Female ( Fig. 22 View FIGURES 19–24 ). Forewing length 4.5 mm; wingspan 9.9 mm (n = 2).

Head. Similar to male. Antenna bright yellow-ochre in basal 1/5.

Thorax. Forewing grey-brown with two very large and two-four small, bright ochre-yellow spots; fringe widely yellow-ochre apically, grey-brown on tornus. Legs metallic glossy, brownish grey to dark brown with some yellowish ochre scales.

Abdomen. Genitalia ( Figs. 49, 50 View FIGURES 47–52 ) about 2210 µm long. Ovipositor lobes small, rounded, clothed with short, modified setae (‘peg setae’); area between ovipositor lobes relatively wide, with tiny papillae and some short setae. Second pair of lobes, lateral and anterior to the ovipositor lobes, twice smaller than ovipositor lobes, but bearing very long lamellar but slender setae. Anterior and posterior apophyses almost equal in length; prela comprised of three pairs of unique projections ( Fig. 49 View FIGURES 47–52 ). Corpus bursae very long and slender, without pectinations or signum. Accessory sac small, rounded. Ductus spermathecae very slender, with about 4 large coils and indistinctive, platelike vesicle.

Bionomics. Host plant is Verbesina   L., possibly V. plowmanii Sagást.   ( Asteraceae   ) ( Figs. 1–3 View FIGURES 1–6 ). Larvae mine leaves and produce blotch-like leaf mines ( Figs. 4–6 View FIGURES 1–6 ). Pupation in a circular nidus inside the leaf mine ( Fig. 5 View FIGURES 1–6 ). Adults occur in November. Otherwise, the biology is unknown.

Distribution. The species is known from the single locality in Urubamba Province (near Machu Picchu), Peru, at an elevation of about 2180 m.

Etymology. The species name is derived from the Ancient Greek mysticus (mysterious), for the unusual dorsal lobe of the valva in the male genitalia.
