Atemelia torquatella: Herrich-Schäffer, 1853: 9 , 33; Pierce and Metcalfe, 1935: 58; Agassiz, 1996: 67; Beavan and Heckford, 2012: 48; Sohn and Peralta, 2014: 340; Lewis and Sohn, 2015: 70.

Atemelia compressella Herrich-Schäffer , [1855]: 112. Type locality: Germany (Mannheim). Oecophora fuscifrontella Stainton, 1849: 13 . Type locality: England (Scotland).

Wingspan 8.5¯ 9.5 mm, male smaller than female. Forewing fuscous, with variable pale creamy spots or fasciae (Figs 4¯7). Males in the extreme case nearly unicolorous, but with white scales traceable on tornus (Fig. 6). Females have more and larger white spots, with those on costa near apex and on tornus sometimes joined (Fig. 7).

Male genitalia ( Fig. 9 ).

Female genitalia ( Figs 13, 13 a) are characterized in the Diagnosis of A. fusca sp. nov.

Pregenital abdomen ( Fig 11 ). Similar to A. fusca sp. nov. Coremata extending out of the body from between sixth and seventh segment, although Moriuti (1977) declared the absence of coremata for Praydidae .
