Abstract

For the first time, the species Betta picta is registered for the southern part of Central Java (Indonesia), being recorded for two localities in the Progo River basin catchment, one in the Magelang and the other in the Bantul Regency, representing an extension of about 100km south to the nearest previously known distribution. These two new records were based on four specimens, three males and one female, collected in February 2019, which were identified as Betta picta since the males possess the main diagnostic features of the species: opercle with yellow-gold iridescence coloration, interrupted stripe below eyes, and a dark subdistal band on caudal and anal fins. Currently, this species is categorized as Near Threatened (NT) by the IUCN, and considering the negative effects of urbanization over the species natural habitats, the new records are important for the species conservation.
