Tolhuaca spiny-chest frog
Alsodes igneus
The paper assigns two populations from the Renaico River area to this species based on phylogenetic, geographic, and morphological similarities. It also says relationships among nearby lineages remain unresolved.[2]
Appearance
The two specimens described from Canoas del Diablo stream were light brown, with a continuous dark brown mark on the front of the back that included a triangle pointing rearward. Lighter, elongated shoulder spots flanked it.[2]
The smaller juvenile from the unnamed stream was reddish brown. Its head’s side band extended beyond the eye to near the arm, and its leaden belly had small, pale yellowish spots.[2]
Life
Canoas del Diablo stream was steep, with a bed made mostly of large rocks and native forest around it. Two-night visits in spring 2015 found several juveniles and many tadpoles, and three juveniles were collected. The unnamed stream had a gentler slope and few rocks in a disturbed area. During a three-night visit in summer 2016, only one small juvenile was seen at the leaf-litter edge on the last night.[2]
Places
Observed places · Chile (two study sites near the Renaico River)[2]
