The genus Isophya has revealed many surprising new insights in the last years. In a recent paper in Zookeys Ionut Iorgu describes yet another Isophya species from the Romanian Carpathians: Isophya dochia . This brings the total number of Isophya species of the Carpathians to the amazing number of 17. Morphologically the new species is identical to I. camptoxypha , but the song is clearly different.
