Trinoridia , gen. nov.

Type species, Trinoridia calcaris , sp. nov.

Description. Moderately small to medium size species. General habitus similar to Calodia ; aedeagus long, tubular with 3 distinctive processes arranged subapically to apex of shaft, glabrous and/or with accessory spines apically on shaft, sometimes with patch of small teeth on dorsal margin; pygofer glabrous or sparsely setose, sometimes with digitate caudoventral process, never with long caudodorsal process, always with small lobe apically; style with short to long apophysis; subgenital plate glabrous or with few apical setae, never with apical spine.

Etymology. The name of the genus is a combination of the Latin root trin - [= three of each] and suffix - idia is derived from the genus Coelidia .

Remarks. The genus Trinoridia is distinguished from related genera by the narrow aedeagal shaft with 3 separate, subapical to apical processes. Two new species and 3 species removed from Calodia are assigned to this genus. The group is widely distributed from India to Malaysia.
