Bufonidae

Bufotes Rafinesque, 1815

Systematics of Bufotes remains complicated despite multiple efforts to clarify the situation of Central Asian taxa. Several levels of ploidy, including tetraploid populations, have been detected in Asian Bufotes ( BASSALAYEVA et al. 1998, KUZMIN 1999, BORKIN et al. 2001, STÖCK et al. 2001, 2005, 2006). Central Asian tetraploid populations have received a variety of denominations through time ( BEDRIAGA 1898, PISANETS & SHCHERBAK 1979), which have been extensively reviewed by STÖCK et al (2001). All examined Mongolian populations of Bufotes are exclusively represented by a tetraploid taxon ( STÖCK et al. 2006, FICETOLA & STÖCK 2016). According to the priority rule, the name of these populations, currently in use, Bufotes pewzowi ( Bedriaga, 1898) , should be retained ( STÖCK et al. 2001). Several subspecies of B. pewzowi were tentatively considered valid by STÖCK et al. (2001) (who proposed several nomenclatural acts and perform some lectotype designations), namely B. p. pewzowi [type locality restricted by lectotype designation to Koyar (Pishan), Xinjian, 37°25´N, 77°10´E], B. p. strauchi [type locality restricted by lectotype designation to: Tarim river, Xinjian (about 41°N, 86°E)], B. p. taxkorensis [type locality: Taxkurgan (37°40´N, 75°12´E), 3120 m a.s.l. (East Pamirs), Xinjiang, China] and B. p. unicolor [type locality: Station Kokmoinok, Chu river valley (about 42°29´N, 75°51´E), Kyrgyzstan]. However, a recent phylogeographic study of B. pewzowi from China and Kazakhstan shows incongruences between the clades and the former intraspecific taxonomy: B. p. strauchi and B. p. taxkorensis were syn- onymized with the nominal subspecies, while B. p. unicolor remains in need of revision ( ZHANG et al. 2008).

The HNHM collection holds material from a single population from Western Mongolia (see Fig. 3 and Appendix).

Strauchbufo Fei, Ye et Jiang, 2012

Represented by a single species, Strauchbufo raddei (Strauch, 1876) , described from Ordos and the Alashan Desert [type locality: Alashan Desert, restricted by lectotype designation in KUZMIN & MASLOVA (2003)], and widely distributed in Mongolia ( BANNIKOV 1958, BORKIN et al. 1986, KUZMIN & ISCHEN- KO 1997, TERBISH et al. 2006, STÖCK et al. 2001). The phylogeographic structure of this species was examined across eastern China. Within this region, three clades have been detected (western, central and eastern) that overlap in northern China, close to the Mongolian border ( DONG et al. 2012). However, the genetic diversity and also the taxonomic status of Mongolian southernmost populations, which were described as an independent taxon ( Bufo koslovi Za- revskij, 1924), need to be reevaluated.

The HNHM collection holds material from 10 localities placed across central and eastern Mongolia, most of them collected by Kaszab (see Fig. 3 and Appendix).
