Summary:[Display omitted] •The usefulness of female genitalia as diagnostic character in Talanga since their signa structures are species specific.•A new endemic species Talanga horake is a new to science.•An identification key of Indonesian Talanga based on external morphology and female genitalia characters. Six species of the genus Talanga Moore 1855 are re-described based on both morphological and genitalia characters. T. tolumnialis Walker is not included due to the lack of available of material. Morphological characters such as a tapering, oblique outwardly antemedial band on the forewing and two black metallic spots externally bordered by similar minute interciliar spots on the hindwing, are proposed as the most appropriate characters to define the genus Talanga. The study also reveals that certain genitalia characters, such as a spatula-shaped uncus, a simple valva with a medial rod-like plate, a long cylindrical phallus without cornuti, a bundle of pencil hairs at the coremata base in male genitalia, and a pair of ovate or circular signa medially bearing denticles in female genitalia, are also diagnostic of this genus. The description of a new endemic species from Foja Mountain, Talanga horakaesp. nov., is presented, as well as an identification key to Indonesian species, and images of adults and genitalia of the studied species.
