03ADA707FFDF1C2B36E2F8CBFC51FCBC.taxon	diagnosis	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). In the male genitalia, the uniquely-shaped carinae of the phallus easily distinguishes A. marmor from all known Acalyptris species.	en	Stonis, Jonas R., Diškus, Arūnas, Remeikis, Andrius, Vargas, Sergio A., Solis, M.

External characters of A. hilli are not always sufficient for species identification, however, the new species differs from the most Neotropical Acalyptris by the silvery glossy forewing with strong purple iridescence and black postmedian fascia (Figs 65 – 67). In the male genitalia, the presence of large cornuti in the phallus, uniquely-shaped uncus (Fig. 77), large, bilobed juxta (Fig. 69), and extremely short vinculum (Fig. 69) easily distinguishes A. hilli from all known Acalyptris species.	en	Stonis, Jonas R., Diškus, Arūnas, Remeikis, Andrius, Vargas, Sergio A., Solis, M.

In the male genitalia, the unique shape of valva with a strongly bulged inner lobe (Fig. 156), and particularly two pairs of extremely developed horn-like processes (Fig. 159) easily distinguish the new species from all known Acalyptris species.	en	Stonis, Jonas R., Diškus, Arūnas, Remeikis, Andrius, Vargas, Sergio A., Solis, M.
