Astrotischeria sanjosei Stonis & Diškus, sp. nov.

(Figs 19–21, 42–46, 88–99)

Type material. Holotype: ♂, PERÚ: Junín Region, La Merced, 11 ° 04ꞌ02.7ꞌꞌS, 75 ° 20ꞌ37.7ꞌꞌW, Fundo San José, 840–900 m, at light, 8–17.v.2018, leg. J. R. Stonis and S. Hill, participation by J. Puplesyte-Chambers, genitalia slide no. AD990 (ZMUC) . Paratypes: 3 ♂ (one with abdomen missing), same label as holotype, genitalia slide no. AD991 (ZMUC) .

Diagnosis. Externally, this new species can be easily distinguished from all other Astrotischeria by the dark color of adults: the entire body is covered either with brown-grey or black scales, which is very unusual for the genus and uncommon for the family in general. In the male genitalia, the combination of a distinct uncus with very short dorsal lobes (Fig. 89); small, weakly developed dorsal process of valva (Figs 92, 94); long but very slender, process-like ventral plate of vinculum (Fig. 98); and apically bilobed but symmetrical phallus distinguishes A. sanjosei from all known congeneric species.

Description. Male (Figs 42–46). Forewing length 3.1–3.3 mm; wingspan 6.6–7.2 mm (n = 4).

Head. Face triangular, covered with grey and some grey cream scales; labial palpus glossy, grey cream to grey; frontal tuft and collar brown-grey; antenna slightly longer than one-half length of forewing; flagellum grey.

Thorax. Tegula, thorax and forewing with very little or no purple iridescence, densely covered with browngrey to black scales; majority of scales cream-tipped (see Figs 42, 46); fringe grey to dark grey, with indistinct and incomplete fringe line, comprised of grey-black scales; forewing underside blackish grey with very little purple iri- descence and without spots or androconia. Hindwing and its fringe concolorous with forewing, without androconia. Legs grey to black grey, with some grey cream scales on underside and tarsi.

Abdomen. Black-grey on upper side and underside, with little purple iridescence; anal tufts (Fig. 44) large, merged dorsally, blackish grey. Genitalia (Figs 88–99) with capsule 465–485 µm long, 215–230 µm broad. Uncus (Fig. 89) comprised of two wide and very short dorsal lobes and two slender and long ventral lobes. Valva (Fig. 98) about 270–290 µm long (excluding the basal process); dorsal lobe weakly developed (Figs 92, 94, 96); transtilla absent; basal process of valva long (Fig. 88). Anellus slightly thickened, mostly membranous, with 2–3 setae laterally (Fig. 96). Phallus about 470–510 µm long, distally deeply bifurcated, symmetrical (Fig. 99), with two small spines on each lobe (Fig. 95).

Female. Unknown.

Bionomics. The host plant is unknown. Adults occur in May, and are attracted to light.

Distribution. The species is known from the single locality, La Merced, Junín Region, central Peru, at an elevation of about 900 m, from the “selva alta” (Figs 19–21).

Etymology. The species is named after a private ecological park, Fundo San José.
