Etymology Soromonichthys is a combination of Soromoni, the name of the creek which serves as type locality for the type species, and the Greek ikhthus, meaning fish. The species epithet stearleyi is a patronym honoring Ralph Stearley, Professor of Geology at Calvin College since 1992, whose patient introductory tutelage in fish osteology set the first author on his career.

Size 30mm or 1.2" SL. Find near, nearer or same sized spp.
Identification Soromonichthys may be diagnosed from all other Hypostominae by having a unique pattern of plate loss on the snout: Soromonichthys has naked skin covering its anteriormost snout margin, extending posteromedially over the mesethmoid to level approximately coequal with anterior bony rim of nostrils, and osterolaterally to about midlength of snout; plated region restricted to column along either side of mesethmoid that becomes broadly expanded posterolaterally to snout margin. There are more details in the original description, this is kept brief on purpose.

The body is dark base with lighter stripes.
