Etymology: Typhlobelus: Greek, typhlos = blind + Greek, belos, -eos, -oys = arrow (Ref. 45335); lundbergi: Named for John G. Lundberg, in recognition of his contributions to neotropical ichthyology, his efforts during the R/V Eastward cruises and the study of demersal fish fauna of large rivers.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical

Morphology | Morphometrics
soft rays: 5;
Vertebrae: 53 - 71. Diagnosed from all its congeners by having four laterosensory pores on the head. Differs further from Typhlobelus ternetzi and T. macromycterus by the absence of eyes; and from T. macromycterus and T. guacamaya by the presence of the four branchiostegal rays (Ref. 56682).
