CHLORODONTOPERA WARREN View in CoL

The genus Chlorodontopera is characterized by the following characters: both fore- and hindwings have large, rounded discal spots, which are larger on the hindwing; a dull reddish-brown patch is present between the discal spot and the costa on the hindwing; in the male genitalia, the socii are stout and setose and the lateral arms of the gnathos are developed, not joined; sternite 3 of the male has setal patches; and veins M 3 and CuA 1 are unstalked on the hindwing. Inoue (1961) suggested that Chlorodontopera is more or less related to Aracima , but he hesitated to place it in the tribe Aracimini . Chlorodontopera was placed in Nemoriini by Hausmann (1996) and in Aracimini by Holloway (1996), followed by Han & Xue (2011a). Prout (1920 –41) referred to the similar morphological characters of Chlorodontopera and Euxena Warren. Later, Holloway (1996) compared Chlorodontopera and Euxena , showing that both genera have similar wing patterns but different genitalia. In this study, Chlorodontopera is sister to the clade including Neohipparchini, Aracimini , Nemoriini , Synchlorini , Comibaenini , Timandromorphini and Geometrini . Chlorodontopera is not related to Aracimini and, therefore, can be excluded from that tribe. Given isolated position, the designation of a new tribe, perhaps including the genus Euxena , is probably appropriate. Further study is needed to confirm a close relationship between these two genera.
