A new endemic fish species from Sri Lanka

Rasbora is a genus of fish that belongs to the family Cyprinidae. they’re distributed all over freshwater habitats in South and Southeast Asia, also as southeast China. Several species are regularly kept in aquariums. There are 80 different species in the world and Sri Lanka is home for 6 species including the new species Rasbora adisi. Rasbora is the most distributed fish genus and Rasbora dandia is the most common freshwater fish species in Sri Lanka. According to the latest studies Rasbora dandia is distributed all over the island, and Rasbora microcephalus is distributed in Nothern and Southwestern areas. These two species are non-endemic Rasbora species that present in Sri Lanka. From the other 4 endemic species, Rasbora wilpita and Rasbora armitagei is restricted to shaded rain-forest streams, Rasbora naggsi is distributed in the Southern part and Rasbora adisi is distributed in the Eastern part of the island (Sudasinghe et al., 2020).

The research was conducted by Hiranya Sudasinghe, Rohan Pethiyagoda, Ranasinghe Hettiarachchige Tharindu Ranasinghe, Rajeev Raghavan, Neelesh Dahanukar, and Madhava Meegaskumbura. The research article was published in the Journal of Zoological Systematics and Evolutionary Research (https://onlinelibrary.wiley.com/doi/abs/10.1111/jzs.12395). This is the first-ever molecular phylogeny of the genus Rasbora in Sri Lanka. The new species, (Rasbora adisi) was named with a noun in apposition, which means mysterious or enigmatic in Sinhala. This is the 5th new freshwater fish species discovered by Mr. Hiranya Sudasinghe this year. We wish you good luck with your works. #TeamWildFreaks
