English Names

Appenine Yellow-bellied Toad (Di Cerbo and Ferri, 1996, Naturschutz Rep., 11: 91).


Peninsular Italy south of the Po River. 


See comment under Bombina variegata for additional discussion. Szymura and Gollmann, 1996, Naturschutz Rep., 11: 9-15, documented strong electrophoretically distinctions between Bombina variegata variegataBombina variegata pachypus, and Bombina variegata scabra.  Bombina pachypus was emoved from the synonymy of Bombina variegata on the basis of genetic distance by Lanza and Vanni, 1991 "1990", in Internatl. Symp. Biogeograph. Aspects of Insularity: 335-344, and Nascetti, Vanni, Bullini, and Lanza, 1982, Boll. Zool., Padua, 49 (Suppl.): 134-135, and on the basis of morphology by (Nascetti, Vanni, Bullini, and Lanza, 1982, Boll. Zool., Padua, 49 (Suppl.): 134-135, where it had been placed by Bonaparte, 1840, Mem. Accad. Sci. Torino, Ser. 2, 2: 446, and Duméril and Bibron, 1841, Erp. Gen., 8: 488. Considered by some authors (e.g., Mertens and Müller, 1928, Abh. Senckenb. Naturforsch. Ges., 41: 16; Arnold, 2002, Rept. Amph. Eur., Ed. 2: 60) to be a race of Bombina variegataLanza and Vanni, 1991 "1990", in Internatl. Symp. Biogeograph. Aspects of Insularity: 337, doubted the reliability of records of this species from Sicily. Lanza, 1983, Guide Reconoscimento Spec. Animali, Anf. Rett.: 83-86, provided an account as Bombina bombina pachypusFromhage, Vences, and Veith, 2004, Mol. Phylogenet. Evol., 31: 308-322, provided molecular data consistent with the recognition of Bombina pachypus as a distinct species but retained it as a member of Bombina variegata. Canestrelli, Cimmaruta, Costantini, and Nascetti, 2006, Mol. Ecol., 15: 3741–3754, discussed molecular phylogeography and Pleistocene biogeography. Yu, Yang, Zhang, and Rao, 2007, J. Herpetol., 41: 365-377, suggested that Bombina pachypus is the sister taxon of Bombina variegatus. See detailed account by Di Cerbo and Bressi, 2007, in Lanza et al. (eds.), Fauna d'Italia, 42 (Amph.): 280-287, for Italian population. Hofman, Spolsky, Uzzell, Cogǎlniceanu, Babik, and Szymura, 2007, Mol. Ecol., 16: 2301-2316, discussed phylogeography of Bombina bombina and Bombina variegata and disputed the species distinctiveness of Bombina pachypus, although their results are also consistent with recognition of additional species within nominal Bombina variegata (DRF). Zheng, Fu, and Li, 2009, Mol. Phylogenet. Evol., 52: 70-83, reported molecular evidence that is consistent with both views. See detailed account by Lanza, Andreone, Bologna, Corti, and Razzetti, 2007, in Lanza et al. (eds.), Fauna d'Italia, 42 (Amph.): 277-280, for Italian population. Speybroeck, Beukema, and Crochet, 2010, Zootaxa, 2492: 6, discussed their reasons from considering Bombina pachypus a subspecies of Bombina variegataFijarczyk, Nadachowska, Hofman, Litvinchuk, Babik, Stuglik, Gollmann, Choleva, Cogǎlniceanu, Vukov, Džukić, and Szymura, 2011, Mol. Ecol., 20: 3381-339, also regarded Bombina pachypus as a diagnosable subspecies of Bombina bombina, but this is a concept- rather than data-based difference of opinion. Mori and Giovani, 2012, Herpetol. Notes, 5: 407–412, documented the disappearance of this species in areas of Tuscany, Italy. Pabijan, Wandycz, Hofman, Węcek, Piwczyński, and Szymura, 2013, Mol. Phylogenet. Evol., 69: 63-74, considered their Bombina variegata scabra to be the sister taxon of Bombina pachypus + Bombina bombina, but treated them as subspecies, an arrangement not followed here because the notion of subspecies has no particular meaning in any concept of species other than the Biological Species Concept, a concept not consistent with phylogenetic aims. The data as they exist are also consistent with three lineage-species: Bombina pachypusBombina variegata, and Bombina scabra (DRF; 23 June 2013). Speybroeck, Beukema, Bok, and Van Der Voort, 2016, Field Guide Amph. Rept. Brit. Eur.: 135–137, provided a brief account (as Bombina variegata pachypus).
