3. Acalyptris marmor Stonis & Diškus , sp. nov. ( Figs 24–29 View FIGURES 24–29 )

Diagnosis. External characters of A. marmor are not always sufficient for species identification, however, the new species differs from most Neotropical Acalyptris by the densely speckled, grey-brown forewing ( Figs 24, 25 View FIGURES 24–29 ). In the male genitalia, the uniquely-shaped carinae of the phallus easily distinguishes A. marmor from all known Acalyptris species.

Description. Male ( Figs 24, 25 View FIGURES 24–29 ). Forewing length 2.5 mm; wingspan 5.5 mm (n = 1).

Head. Scape yellowish cream with some pale ochreous scales; frontal tuft pale orange; collar comprised of greyish orange piliform scales; antenna slightly shorter than one-half length of forewing; flagellum dark grey-brown on upper side, brownish cream on underside, with 34 segments.

Thorax. Tegula, thorax, and forewing densely speckled with dark grey-brown and black-brown scales with some blue and purple iridescence; fringe grey, without fringe line; forewing underside blackish brown, without spots or androconia. Hindwing and fringe grey to dark grey on upper side and underside, without androconia. Legs silvery glossy, ochre cream, with black-brown scales on upper side.

Abdomen. Blackish grey with some purple iridescence on upper side, glossy, metallic grey on underside; anal tufts short, dark grey; genital plates brownish cream. Genitalia ( Figs 26–29 View FIGURES 24–29 ) with capsule about 330 µm long, 200 µm wide. Phallus about 215 µm long, with unique, wide ventral carinae ( Figs 28, 29 View FIGURES 24–29 ).

Female. Unknown.

Bionomics. Host plant is unknown. Adults fly in May (one specimen was attracted to light). Otherwise, biology is unknown.

Distribution ( Fig. 1 View FIGURE 1 ). Currently known from a single locality in Peru, Departamento de Junín: Selva Central, Satipo, at an altitude about 750 m ( Figs 2–5 View FIGURES 2–11 ).

Etymology. The species name derived from the Latin marmor (marble, stone), in reference to the dark greybrown speckled forewing of the new species.

Type material. Holotype: ♂, PERÚ, Junín Region, Satipo , 11°15ꞌ30ꞌꞌS, 74°37ꞌ56ꞌꞌW, 750 m, at light, 13– 15.v.2018, leg. J. R. Stonis & S. R. Hill, genitalia slide no. AD950 ( ZMUC).
