Small-webbed Bell Toad, Hubei Fire Bellied Toad or Yunnan Fire Bellied Toad
Description: Body length of an adult male B. microdeladigitora holotype was recorded at 77 mm. The head is broader than long, tympana are hidden, and the arms are relatively long and fingers short with distinct fringes at their base, forming web-like structures. The dorsal skin of the head, body, and limbs is very rough and covered in warts. The snout and lateral sides of the head, body and limbs are much smoother. Four elongated warts form an X mark on the shoulder region (Liu et al. 1960).
Coloration: When alive, the dorsal side is greenish with dark black to brown marks along scattered warts, which can be both small and large. Black vertical bars mark the jaws and one wide black bar marks each thigh. A black color dominates the ventrum with fewer orange-red marks (Liu et al. 1950).
Coloration in Preservative: After preservation, the greenish color changes to dark grey and the brown and orange-red turns to white (Liu et al. 1960).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: China, Viet Nam
Possible reasons for amphibian decline
Habitat modification from deforestation, or logging related activities
Phylogenetic Relationships: The genus Bombina is currently divided into three major clades: the European and Korean groups, which form a sister relationship, and the Indo-Malay clade to which B. microdeladigitora belongs (Zheng et al. 2009). Due to the low levels of genetic, morphological and karyological differences, it has been suggested that B. microdeladigitora and B. fortinuptialis be reassigned as subspecies of B. maxima (Yu et al. 2007).
