The Overlooked Squeaker Frog was described in 2012, the species bears its name for the fact that the single type specimen was found hidden among fifty to sixty specimens of another frog species, the Rugege Forest Squeaker Frog (
Arthroleptis adolfifriederici Nieden), in an ethanol-filled glass put away at some storage rack in the Museum of Comparative Zoology, Harvard University in Cambridge, Massachusetts, USA.The species reached a size of about 4 cm (snout to vent), its coloration is not known because the colors of the type specimen have heavily faded.
The type specimen was collected in 1930 in the Ngozi crater in the Poroto Mountains in Tanzania together with several other frog species. Another specimen popped up in 2013, one year after the species’ description, in the Museum für Naturkunde Berlin, Germany.
The Overlooked Squeaker Frog was never found again and is believed to be extinct. [1][2]
