Simpsonichthys longignatus
Costa, W. J. E. M, 2008
Abstract

Simpsonichthys longignatus, new species, from the Pacoti River basin, an isolated coastal drainage of northeastern Brazil, is described. It is considered to be closely related to three species of the Tocantins River basin, S. multiradiatus, S. flammeus and S. brunoi, by all possessing bright blue anal fin in males and concave dorsal profile of head. It differs from those three species by having black spots on the anterior part of the dorsal fin and transverse series of small blue spots on the caudal fin in males. It is also distinguished by some features in combination, including numerous dorsal-fin rays in males, absence of long filaments on the dorsal and anal fins, and few neuromasts on supraorbital, infraorbital, preopercular and mandibular series.
