A new species of Isometrus (Reddyanus) from caves in Myanmar

 


Update 29.01.25:  In agreement with author Eric Ythier, the new species has been included in the genus Reddyanus in The Scorpion Files to avoid any confusion until the status of  Reddyanus has ben resolved.

Eric Ythier and Wilson Lourenco have recently published a new species of Isometrus Ehrenberg, 1828 (Buthidae) from Saddan Cave in eastern Myanmar (Burma).

The authors do not accept the genus status for the subgenus Reddyanus Vachon, 1972, which is used in The Scorpion Files. I have listed the new species in Isometrus, but it probably belongs in Reddyanus (depending on how you view the status of the genus/subgenus).

The new species was found in a cave, but has no troglomorphic characters.

Abstract:
A new species belonging to the genus Isometrus Ehrenberg 1828, subgenus Reddyanus Vachon, 1972, is described from Myanmar: Isometrus (Reddyanus) alessandroi sp. n., which was collected in Saddan Cave, located in Kayin State, in the East of the country. In recent years the number of new species added to both subgenera Isometrus and Reddyanus have increased remarkably. Nevertheless, none of these descriptions concerned Myanmar. This particular geographic situation as well as a combination of several morphological features led us to propose here this new species.
