The site was a marginal sand bank forming a small island. Found in an area with moderate current (approx. 40 cm/sec), depths up to 35 cm, markedly warm water (30-33uC on the surface), horizontal transparency varied between 2.5 and 3.2 m and pH 6.5-7.0. de Pinna, M.C.C. and J.

It can be further distinguished from all its congeners by the following characters: absence of the anal fin (vs. presence); presence of one or two well-developed opercular odontodes (vs. absence); presence of anteroventral and dorsal processes of the opercle (vs. vestigial and absence, respectively). It further differs from both Typhlobelus macromycterus and T. guacamaya by having 4 branchiostegal rays (vs. 5 and 3, respectively); and from T. guacamaya and T. lundbergi by having some premaxillary teeth (vs. teeth absent) (Ref. 94274). de Pinna, M.C.C. and J.
