Treatment

Astrotischeria amazonica Diškus & Stonis View in CoL , sp. nov.

( Figs. 4–6 View FIGURES 4–6 , 70–82 View FIGURES 70–78 View FIGURES 79–82 , 233 View FIGURE 233 , 241–244 View 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. 70 View 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. 4–6 View FIGURES 4–6 , 71–82 View FIGURES 70–78 View 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. 74 View FIGURES 70–78 , 79 View FIGURES 79–82 ). Valva divided ( Figs. 4–6 View FIGURES 4–6 ); ventral lobe ( Fig. 75 View FIGURES 70–78 ) slender; dorsal lobes consisting of two large, horn-like processes ( Fig. 6 View FIGURES 4–6 ); transtilla absent. Anellus thickened laterally, with 3 setae ( Figs. 76 View FIGURES 70–78 , 79 View FIGURES 79–82 ), membranous posteriorly. Phallus about 520 µm long, distally deeply bifurcated, without spines ( Figs. 71, 72, 78 View FIGURES 70–78 ).

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

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