established the genus Ami to accommodate several small theraphosids from northern Brazil, Ecuador, Colombia, Venezuela and Panama, characterized by having modified type I urticating setae and other unusual characters which did not fit any known theraphosid genus, especially the shape of spermathecae in females and the presence of one or two subconical
processes on male palpal tibia, in combination with a palpal bulb with very short and stout embolus carrying two prolateral keels.

Individuals captured (CORBIDI 010299-010301) exhibit diagnostic characteristics mentioned by Duellman and Hedges (2008) such as: tympanic membrane not differenced and tympanic annulus absent, upper eyelid bearing small tubercles, vocal slits and nuptial pads absent, subconical
tubercle on the heel and outer edge of tarsus with row of subconical
tubercles and a green dorsal coloration.
Third to fifth pereopods moderately stout, notably decreasing in length from third to fifth; dactyli subconical

The specimens of fangjaw eel were identified using the following combination of diagnostic characteristics (Castro-Aguirre and Suarez de los Cobos 1983; Allen and Robertson 1994): body elongated, cylindrical, pointed at both ends; tail longer than head and trunk; pectoral fins present; gill opening relatively elongate, vertical and lateral; snout short, subconical
, slightly constricted near tip; teeth very strong and pointed, biserial, largest anteriorly on jaws; body overall tan with abundant small, brown spots on back and sides; and dorsal fin brown.
