Hasumi, M.: Secondary sexual characteristics of the salamander Salamandrella keyserlingii: throat coloration. Herpetological Review (USA, International) 32(4): 223-225, December 2001.

Abstract: Salamandrella keyserlingii during the terrestrial phase had a unique, sexually dimorphic trait, characterized by white (September-October) and yellow (April-May) pigmented patches in the throat region of adult males, which was not reported previously. A tubercle at the anterior angle of the vent was never discernible in either sex throughout the year, even during the aquatic phase. Aquatic-phase males exhibited increased head width, tail height, and body mass, similar to those of Hynobius nigrescens.
