最近在日本西部琉球群岛奄美群岛发现的一种鳄蝾螈，被认为是鳄蝾螈的奄美支系。来自冲绳的安德松，它在形态上非常相似，但遗传上不同。在E. raffaellii，只有两个标本，包括一个出生在圈养，只有有限的形态比较与E.安德森是做出来的。本文研究了E. raffaellii与大量的标本进行了比较，并与E. andersoni，并澄清了他们的独立的具体地位。
A crocodile newt, Echinotriton raffaellii, recently described from the Amami islands in the Ryukyu archipelago, western Japan has been regarded as Amami lineage of E. andersoni from the Okinawa islands, to which it is morphologically very similar, but genetically divergent. In the original description of E. raffaellii, only two specimens, including one born in captivity, were examined and only limited morphological comparisons with E. andersoni were made. Here we examined the morphological characteristics of E. raffaellii with an ample set of specimens, compared them with those of E. andersoni, and clarified their independent specific statuses.
