Subtiaba language
Subtiaba is an extinct Oto-Manguean language which was spoken on the Pacific slope of Nicaragua, especially in the Subtiaba district of León. Edward Sapir established a connection between Subtiaba and Tlapanec. When Lehmann wrote about it in 1909 it was already very endangered or moribund.Lexical comparison from Native American Language Net:
