Scientific Name Tympanopleura cryptica  Walsh, Ribeiro & Rapp Py-Daniel, 2015
Common Name Dusky Dwarf Duck Catfish
Type Locality Loreto, río Solimões drainage, río Orosa, mouth of Tonche Cano, 69.4 mi east of Iquitos, about 3°47'26"S, 73°14'50"W, Peru.
Etymology Transliterated from the Greek tympanon, meaning drum, and pleura, meaning side or rib (pleuron), nouns in apposition, in reference to the pseudotympanum. The specific epithet cryptica is derived from the transliterated Greek kryptos, meaning hidden or concealed, in reference to the close morphological and pigmentation similarities of this species to congeners and its previously unrecognized taxonomic distinctiveness.
