Comment | Bipes is the only genus of amphisbaenians that shows forelimbs. Type species: Bipes canaliculatus is the type species of the genus Bipes LATREILLE 1801. Bipes is also the type genus of the family Bipedidae Taylor, 1951. Distribution: Campbell (1980 and Smith & Holland (1981) speculated that Bipes sp. may rarely occur in E Colorado and W Nebraska based on old reports. Taylor 1938 speculates that Bipes may occur in Arizona, based on some observations reported to him. Not in Morelos fide Lemos-Espinal 2020. Nomenclature: This species “was described as "Le Cannele" in the text of Lacepede (1788), but in the Synopsis methodica of that work, a large fold out table, the Latin name "B. canaliculatus" appeared for it. Bonnaterre (1789) also used Lacepede's name B. canaliculatus, without interpreting the initial.” Only Latreille (1801) explicitly derived the genus name, hence authorship for both the generic and specific names of Bipes canaliculatus lies with Latreille (1801), as pointed out by Brygoo (1990). See Flores-Villela et al. 2004 for details. Nevertheless, Gans 2005: 40 listed it as Bipes canaliculatus (Bonnaterre). |
Etymology | Name based on ‘‘le cannelé’’ of La Cépède, 1788–1789: 613 The genus was named after Latin bi-, two, twice; double; having two + Latin pes, foot. [“...Point de pattes postérieures; les antérieures très-petites...”]. |
