Epitonga Fennah, 1954

Epitonga Fennah, 1954: 462 . Type species: Epitonga ferox Fennah, 1954 (by original designation).

The genus Epitonga was erected by FENNAH (1954) for a single species from the Solomon Islands (New Georgia Island) and distinguished by the peculiar convex “shoulders” (a strong bulge near to basal cell) of fore wings (in dorsal view), narrow metope, and leaf-shaped lateral margins of the narrow coryphe. According to Melichar’s illustration ( MELICHAR 1906: Fig. 42) Lollius gratiosus Melichar, 1906 from New Guinea apparently belongs to Epitonga as well.

The genus Lollius Stål, 1866 (= Okissus Matsumura, 1916 = Ecapelopterum Chan & Yang, 1994 ; synonymy after GNEZDILOV 2009) is characterized by a quite wide metope with two sublateral carinae joined in the shape of an inverse letter ‘V’ ( FENNAH 1954, GNEZDILOV 2009) and a quite wide coryphe without leaf-shaped lateral margins. The genus is widely distributed from Australia and New Guinea to Taiwan and the Ryukyus and currently includes 24 species ( BOURGOIN 2014).
