Siagonodon unguirostris

Cordoba Thread Snake, Southern Thread Snake

Cordoba-Fadenschlange

Cordoba-trådslange

1902 Glauconia unguirostris Boulenger
Leptotyphlops unguirostris Serié 1921
Rena unguirostris Adalsteinsson, Branch, Trape, Vitt & Hedges 2009
Siagonodon unguirostris Wallach, Williams & Boundy 2014

Remarks: Previously assigned to the genus Rena (e.g., Adalsteinsson, Branch, Trape, Vitt & Hedges 2009). Included in the genus Siagonodon herein, following Wallach, Williams & Boundy (2014), although these authors did not present any evidence for their reassignment of the species. Considering its distribution, it does seem unlikely, though, that unguirostris should belong in the otherwise strictly North American genus Rena.
Distribution: Argentina, Bolivia, Paraguay.
