Material examined: 6 ♀, 13 of undetermined sex from the Galápagos Islands: – San Cristóbal: 4 km SE P[uer] to Baquarizo [sic]; La Toma, ca. 6.5 km east El Progreso, GPS: 299 m elev[ation]., S 00° 55.356’, W 89° 31.089’. – Santa Cruz: Charles Darwin Research Station; Charles Darwin Research Station, base of El Barranco, GPS: S 00° 44.305’, W 90° 18.105’; Horneman Farm, 220 m; Media Luna, pampa zone. Deposited in CAS, CDRS, CNC, MCZ, and MHNG.

Diagnosis: In the Galápagos this species ( Fig. 16View Figs 9 - 16) is similar to Diaphania hyalinata  (L.) ( Fig. 15View Figs 9 - 16), but it is generally smaller (19-25 mm versus 26-29 mm) and its forewing dark brown marginal band slightly expands anteriorly before reaching the inner margin whereas this terminal band is straight until the inner margin in D. hyalinata  .

Biology: The larva feeds on various Cucurbitaceae  , but it has also been recorded on Annonaceae  , Fabaceae  , Malvaceae  , Oleaceae  , Poaceae  , and others ( Robinson et al., 2014). In the Galápagos, in contrast to D. hyalinata  , D. indica  was collected mostly in anthropized habitats in the littoral zone, but also in the highest (pampa) zone at about 700 m in elevation on Santa Cruz. Collecting dates of the available Galápagos specimens are in February and March.

Distribution: Around the world in tropical, subtropical and warm temperate regions on all continents (including Australia) and many islands ( BMNH and MHNG specimens; Shaffer et al., 1996; Robinson et al., 2014). In the Galápagos it has been collected so far on San Cristóbal and Santa Cruz, but see above under Distribution for Diaphania hyalinata  (L.).

Remarks: I confirmed the identification of a Galápagos specimen by comparing it with specimens in the BMNH. The latter had been curated by Michael Shaffer, who wrote to Jack Clarke about two syntypes of D. indica  found in the University Museum of Oxford and his manuscript lectotype and paralectotype designations, made available by Clarke (1986: 80).
