Astrotischeria yungasi Diškus & Stonis

sp. nov.

Astrotischeria yungasi Diškus & Stonis   , sp. nov.

( Figs. 7–9 View FIGURES 7–10 , 23, 24 View FIGURES 19–24 , 35–40 View FIGURES 35–40 , 47, 48 View FIGURES 47–52 )

Type material. Holotype: ♂, BOLIVIA: Nor Yungas Province , Coroico, 16°12’25”S, 67°43’53”W, elevation ca. 1660 m, from feeding larva, field card no. 5268, leg. A. Diškus, J. R. Stonis, slide no. AD1070 (from adult in pupal exuvia) ( ZIN) GoogleMaps   . Paratypes: 1 ♂, 2 ♀, same label data as holotype, genitalia slides nos. AD1034 GoogleMaps   ♂ (from adult in pupal exuvia), AD1068 ♀ ( ZIN)   ; 1 ♂, same label data, genitalia slide no. AD1069 ♂ (from adult in pupal exuvia) ( NRC)   .

Diagnosis. Externally, this new species can be confused with other speckled Astrotischeria species   , including A. mystica   sp. nov. and A. parapallens   sp. nov. (both described herein), but A. yungasi   sp. nov. is slightly darker and smaller, 7.2–7.6 mm in wingspan. In the male genitalia, A. yungasi   is the most similar to A. dondavisi Stonis & Diškus   (see Stonis et al. 2019a) and A. truncata Diškus & Stonis   (see Stonis et al. 2018). From the latter, yungasi   differs in the absence of a short, truncated basal lobe of the valva, long vinculum, and the wide uncus. From A. dondavisi   , A. truncata   differs in the long vinculum, large dorsal lobes of the valva, large lobes of the uncus, and slender base of the phallus. In the female genitalia, character validity would be speculative because many Astrotischeria   females are unknown and are undiscovered. Also see Remarks.

Male (see Remarks). Genitalia ( Figs. 35–40 View FIGURES 35–40 ) with capsule 540–580 µm long, 210–225 µm wide. Uncus ( Figs. 35, 36 View FIGURES 35–40 ) comprised of four lobes: two wide dorsal and two slender and slightly shorter ventro-lateral lobes. Valva ( Figs. 35, 37, 39 View FIGURES 35–40 ) about 305 µm long (excluding the basal process); two dorsal lobes greatly developed (see Fig. 39 View FIGURES 35–40 ); basal process of valva long ( Fig. 39 View FIGURES 35–40 ). Anellus indistinctive, mostly membranous, with 2–3 setae laterally ( Fig. 40 View FIGURES 35–40 ). Vinculum long, distally rounded. Phallus about 610 µm long, distally with two long and slender lobes ( Fig. 38 View FIGURES 35–40 ).

Female ( Figs. 23, 24 View FIGURES 19–24 ). Forewing length 3.3–3.5 mm; wingspan 7.2–7.6 mm (n = 2).

Head. Frons, palpi, and pectens pale yellow-ochre; frontal tuft comprised of distinctly wide, very glossy scales with some purple iridescence; frontal tuft metallic grey medially, dark golden yellow laterally and distally; collar pale ochre, inconspicuous; antenna slightly longer than one half the length of forewing; flagellum grey to blackish grey, sometimes indistinctly annulated with grey-cream.

Thorax. Tegula dark grey with purple iridescence, distally pale ochre; thorax pale ochre to bright ochre, sometimes grey medially. Forewing densely speckled with blackish grey or dark brown scales with some purple iridescence; three large oblique spots comprised of bright, very intense, yellow-ochre scales; fringe blackish grey; fringe line comprised of blackish brown scales; forewing underside dark grey-brown to blackish grey, without spots or androconia. Hindwing dark grey on upper side and underside, without androconia; fringe grey. Legs glossy grey, forelegs black-grey on upper side.

Abdomen. Very glossy, with some purple iridescence, metallic grey on upper side and underside, distally with pale ochre cream gloss on underside; genital segments grey. Genitalia ( Figs. 47, 48 View FIGURES 47–52 ) about 1250 µm long. Oviposi- tor lobes small, oval, 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, very small, bearing a few very long slender setae, without stout, modified ‘peg setae’. Posterior and anterior apophyses almost equal in length; prela comprised of three pairs of unique, rod-like projections. Corpus bursae long and narrow, distally oval-shaped ( Fig. 47 View FIGURES 47–52 ), without pectinations or signum. Accessory sac inconspicuous, oval-shaped; ductus spermathecae very slender with 3 or 4 very large coils.

Bionomics ( Figs. 7–9 View FIGURES 7–10 ). Host plant is Oyedaea DC.   ( Asteraceae   ), most likely the species O. boliviana Britton   , which grows in this region of Bolivia ( Fig. 9 View FIGURES 7–10 ). Larvae mine leaves in June. The blotch mine ( Figs. 7, 8 View FIGURES 7–10 ) is very long, developed along the leaf margin; at the final stage the mine bends (distorts) the leaf ( Figs. 7, 8 View FIGURES 7–10 ). Pupation inside the leaf mine. Adults occur in late June–July. Otherwise, biology is unknown.

Distribution. The species is known from the single locality in Bolivia (Nor Yungas Province: Coroico) at an elevation of about 1660 m.

Etymology. The species is named after the Nor Yungas Province where it was discovered.

Remarks. The external species description is based exclusively on female adults since all three available males are known from pupal exuviae (no pinned male adults are preserved).

Our unpublished molecular study shows A. yungasi   sp. nov., A. dondavisi Stonis & Diškus   and A. truncata Diškus & Stonis   as three separate species; a phylogenetic tree will be published separately with a molecular analysis of Tischeriidae   (Stonis et al. in prep.).
