“…Argenteohyla siemersi is included in the tribe Lophiohylini Miranda‐Ribeiro, 1926, together with Aparasphenodon , Corythomantis , Itapotihyla , Nyctimantis , Osteocephalus , Osteopilus , Phyllodytes , Phytotriades , Tepuihyla and Trachycephalus , which form a monophyletic clade (Faivovich et al ., ; Duellman, Marion & Hedges, ) known as ‘casque‐headed frogs’ (Faivovich et al ., ). Like some other casque‐headed frogs, A. siemersi (1) has a heavily ossified skull and sculptured dermal bone that is co‐ossified with the overlying skin (Trueb, ); (2) takes refuge in bromeliad leaf axils (Cei & Pierotti, ; Cajade, Marangoni & Gangenova, ); and (3) presumably displays phragmotic behaviour by backing into axils and flexing the head at a right angle to the body (Barbour, ; Firschein, ; Trueb, ), as suggested by Trueb () and Lutz & Barrio (). However, this behaviour has not been observed in A. siemersi .…”
