    Nyctibatrachus Mewasingh


  • Since many frogs in genus Nyctibatrachus look similar, scientists used both physical characteristics as well as genetic methods to confirm frog as new species.
  • Using tissue samples of 10 collected specimens of newly discovered species, scientists analysed portions of two genes and found that it varied enough from other closely-related species to make it different species.
