Rana lessonae Camerano 1882

Peter Beerli*

Table of Contents



A member of the water frog group with green backs which show black spots in females. Males are brightly yellowis-green during mating season. [More to follow..]


In the west it extends to the Atlantic Ocean in France, in the north are a few populations in Sweden, in the northeast the distribution extends beyond St. Petersburg, the southern border is assumed to be the Danube in the east. Problematic is the distribution in Italy, the species is considered to be distributed throughout the Po valley, but seems to be parapatric with an unnamed peninsular taxon (the peninsular non-hybrid, D_Nei >= 0.2). In Kalabria Santucci et al. (pers. comm., 1995) found an other hybrid zone (genetic differences between parental taxa are D_Nei = 0.4) suggesting that an other species is occurring in the southermost Kalabria and Sicily (southern non-hybrid).
