About the Hudson's Humming Frog

Chiasmocleis hudsoni, also known as Hudson's humming frog, is a species of frog in the family Microhylidae. It is found in French Guiana, Suriname, Guyana, Guianan Venezuela, Colombia (Amazonas), and Amazonian Brazil. Chiasmocleis jimi has been included in this species but the most recent genetic analyses support its recognition as a distinct species; both species might include further distinct lineages that warrant recognition as species.

The specific name hudsoni honours C. A. Hudson, the collector of the holotype and a collector for the Natural History Museum, London. Adult males measure 14–23 mm (0.6–0.9 in) and adult females 17–28 mm (0.7–1.1 in) in snout–vent length. The body is robust and ovoid. The head is much narrower than the body; the snout is rounded. All but the first finger are fringed; no webbing is present. The finger tips are rounded and fingers 2–3 are swollen and may present discs. The toes are slightly fringed but have no webbing. Toes 2–4 have terminal discs. The dorsum is purple brown with variable lighter markings. The snout can be white.

Males may possess few but large dermal spines on the chin. The male advertisement call... Wikipedia →
