扁蟾屬
扁蟾屬（學名：Incilius），俗稱中美洲蟾蜍，是蟾蜍科的屬[2]，分布於美國南部、墨西哥、中美洲地區和南美洲北部（哥倫比亞和厄瓜多）。扁蟾屬是生態和生物地理多樣化的蟾蜍群，包括一些微小的特有種，如只分布於雲霧森林的Incilius spiculatus，以及Incilius valliceps等分布於干擾生境的低地物種[3]。

分類學和系統學
扁蟾屬的分類學和系統學最近發生了很多變化。2011年，Cranopsis、Ollotis、Crepidius和Crepidophryne成為扁蟾屬的異名。但是，扁蟾屬是單系群的觀點受到了Incilius bocourti的威脅，因為Incilius bocourti可能是Anaxyrus的姐妹群[1]。
另一個討論是識別該屬的分類學水平。在2006年達爾·弗羅斯特及其同事大規模修訂兩棲動物系統學之前，扁蟾屬並沒有得到廣泛的認可[4]，而是以Cranopsis的名義存在，包括前「垣頭蟾組」及其相關物種。但是，另外一些學者認為扁蟾屬應該被看做蟾蜍屬的亞屬[5]。

- Incilius nebulifer (Girard, 1854)
- Incilius occidentalis (Camerano, 1879)
- †金蟾蜍（Incilius periglenes） (Savage, 1967)
- Incilius peripatetes (Savage, 1972)
- Incilius perplexus (Taylor, 1943)

- Incilius signifer (Mendelson, Williams, Sheil, and Mulcahy, 2005)
- Incilius spiculatus (Mendelson, 1997)
- Incilius tacanensis (Smith, 1952)
- Incilius tutelarius (Mendelson, 1997)
- Incilius valliceps (Wiegmann, 1833)
AmphibiaWeb認可Incilius intermedius (Günther, 1858)是有效物種，而Amphibian Species of the World認為Incilius intermedius是Incilius occidentalis (Camerano, 1879)的異名[6][1]。
