Diagnosis: Among Galápagos Spilomelinae this species ( Figs 41, 42View Figs 41 - 48) could only be confused with Salbia haemorrhoidalis Guenée  ( Figs 51, 52View Figs 49 - 56) by virtue of their similar, mostly orange colour, although some specimens of O. indicata  are mostly purplish brown ( Fig. 41View Figs 41 - 48). The 14-20 mm wingspan O. indicata  differs in harbouring a thicker, more contrasting dash in the forewing cell, a smaller spot anteriorly in the cell (usually), and a submedian dash near costa separate from the wavier and more rounded submedian line in the hindwing usually. On the other hand the male abdomen of S. haemorrhoidalis  has apical white and black patches on the last and penultimate segments dorsally.

Biology: In the Galápagos I reared a specimen from a pupa found on Desmodium glabrum (Mill.)  DC. ( Fabaceae  ) and another specimen from Rhynchosia minima  (L.) DC. ( Fabaceae  ), both Galápagos natives found on a large number of islands (Jaramillo Díaz & Guézou, 2015). The literature also records a wide spectrum of host plants in the Fabaceae  , but also in other families ( Acanthaceae  , Amaranthaceae  , Annonaceae  , Asteraceae  , Chenopodiaceae  , Cucurbitaceae  , Euphorbiaceae  , Lamiaceae  , Malvaceae  , Poaceae  , Solanaceae  , and Verbenaceae  ) ( Gentili & Solis, 1998; Robinson et al., 2014). The Galápagos specimens were collected from a diverse range of habitats from the littoral zone up to 1240 m above sea level, and from February until May.

Distribution: This is a widespread species in the tropical regions of the world ( Gentili & Solis, 1998). Based on BMNH specimens it can be found in Cuba, Jamaica, Grenada, St Vincent, St Thomas, Santo Domingo, Trinidad, Mexico, Guatemala, Costa Rica, Honduras, Colombia, French Guiana, British Guiana, Brazil, Paraguay, Peru, Africa, Seychelles, Solomon Isl., India, Java, Taiwan. It is also widespread in the south-eastern US States ( Patterson et al., 2015). In the Galápagos it is known from Fernandina, Isabela, Pinta, San Cristóbal, Santa Cruz, and Santiago.

Remarks: Galápagos specimens were identified as this species based on Gentili & Solis (1998) and material in the BMNH, in which is deposited the type material of some of the synonyms, such as Nacoleia vulgalis Guenée, 1854  (TL: French Guyana, Cayenne), Botys moeliusalis Walker, 1859  (TL: Malaysia), and Botys connexalis Walker, 1866  (TL: Dominican Republic). The type material of Botys sabalis Walker, 1859  (TL: Brazil) and Botys reductalis Walker, 1866  (TL: China), also synonyms of O. indicata  , could not be found in the BMNH.
