Preta Distant, 1908: 234.

Type-species.

Preta gratiosa (Melichar, 1903).

Diagnosis.

Head ( Figs 8, 9 ) strongly and angulately produced. Pronotum ( Figs 8, 9 ) with pair of well-developed submedial longitudinal carinae extended entire length. Forewings ( Fig. 17 ) with claval veins fused for short distance near midlength.

Notes.

Preta is restricted to the Oriental region and currently includes two species, Preta gratiosa and Preta luzonensis Baker, 1923, the latter known only from the Philippines. It can be easily distinguished from Signoretia by its complete paired longitudinal carinae on the pronotum ( Fig. 8 ) and medially fused claval veins of forewings ( Fig. 17 ), as indicated in the key.

Distribution.

Indonesia (Sumbawa, Jacobi 1941 apud Knight 2010), E. and W. Malaysia ( Baker 1923), Myanmar ( Distant 1908), Philippines (Luzon, Baker 1923), Singapore ( Baker 1923), Sri Lanka ( Melichar 1903), and Thailand [new record].
