Astrotischeria amazonica Diškus & Stonis  , sp. nov.

( Figs. 4–6View FIGURES 4–6, 70–82View FIGURES 70–78View FIGURES 79–82, 233View FIGURE 233, 241–244View FIGURES 239–244)

Type material. Holotype: ♂, ECUADOR: Napo Province, 1 km N Misahualli, 1°01'28"S, 77°40'02"W, elevation 440 m, 07.ii.2007, V. Sruoga, genitalia slide no. AD 929♂ ( ZMUC).

Diagnosis. The combination of a very wide uncus and two horn-like dorsal lobes of valva in the male genitalia distinguishes A. amazonica  sp. nov. from all other Astrotischeria  , including other members of the A. trilobata  group.

Male ( Fig. 70View FIGURES 70–78). Forewing length about 2.5 mm; wingspan about 5.4 mm. Head: face, palpi and frontal tuft glossy, pale ochre cream; pecten indistinct in the poorly preserved holotype (see Remarks); antenna with about 35–37 segments, longer than half the length of forewing; flagellum cream on upper side, dark grey on underside; sensillae long and fine, whitish cream. Thorax and tegula pale brownish grey. Forewing, except for a few large, irregular pale orange-ochre patches, densely speckled with brown-grey scales; some of these scales with ochre cream tips and little blue, green or purple iridescence; fringe black-grey, including the forewing apex; fringe-line indistinct; forewing underside dark greybrown, without spots or androconia. Hindwing brownish grey, without androconia; fringe grey-brown. Legs pale brownish grey, with rather strong golden gloss; foreleg and midleg densely speckled with grey-brown scales on upper side. Abdomen brownish grey, distally brownish cream on underside; anal tufts indistinct, grey; genital plates grey.

Female. Unknown.

Male genitalia ( Figs. 4–6View FIGURES 4–6, 71–82View FIGURES 70–78View FIGURES 79–82). Capsule about 465 µm long, 200–210 µm wide. Uncus consisting of two slender lateral lobes and two short but very wide median lobes ( Figs. 74View FIGURES 70–78, 79View FIGURES 79–82). Valva divided ( Figs. 4–6View FIGURES 4–6); ventral lobe ( Fig. 75View FIGURES 70–78) slender; dorsal lobes consisting of two large, horn-like processes ( Fig. 6View FIGURES 4–6); transtilla absent. Anellus thickened laterally, with 3 setae ( Figs. 76View FIGURES 70–78, 79View FIGURES 79–82), membranous posteriorly. Phallus about 520 µm long, distally deeply bifurcated, without spines ( Figs. 71, 72, 78View FIGURES 70–78).

Bionomics. Adults fly in early February. Otherwise biology unknown.

Distribution ( Fig. 233View FIGURE 233). Known from a single locality in Ecuadorian Oriente, disturbed Amazonian rainforest habitat at the elevation of about 440 m ( Figs. 241–244View FIGURES 239–244).

Etymology. The species name is derived from the Amazon Basin, a place name of South American region in reference to the occurrence in the Amazonian rainforest.

Remarks. Head of the holotype is broken, placed in a plastic tube.
