The adult female runs to N. fittkaui in the key to females provided by Wirth and Ratanaworabhan (1972). Of the eight recognized species of Neobezzia, only the males of N. amnicola and N. wirthi Spinelli & Felippe-Bauer, 1990 are known. The male of N. fittkaui is easily recognized from those species by its stouter aedeagus and the shape of the tip of the fused parameres (a spatulate lobe in N. amnicola, blunt and not bulbous in N. wirthi).
The pupa of Neobezzia is very similar to some species of the Holarctic genus Probezzia Kieffer, 1906. Both groups have the abdominal tergites 1-7 with dorsal anterosubmarginal sensillae i and dorsal posteromarginal seta i on short sclerotized tubercles, and the fourth abdominal sternite with v.p.m. iii on a bifid tubercle. However, Neobezzia can be distinguished from these Probezzia by the lateral anterosubmarginal seta i on the fourth abdominal segment being a medium-sized, thin seta on a strong triangular tubercle (this seta short, thin, on small, apically rounded tubercle in Probezzia fuscipennis Wirth, 1971). A complete generic key for the pupae of Ceratopogonidae will be published elsewhere (Borkent, in prep.).
The description of the pupa of N. amnicola by Mayer (1959) is incomplete. The spiracles of the respiratory organ and the number of sensillae on the abdominal segments are apparently the same as those of N. fittkaui; Mayer (1959) did not note the size or shape of the associated tubercles. Neobezzia amnicola apparently lacks the pore situated lateral to the two ventrolateral setae. These are the only cephalothoracic setae mentioned by Mayer (1959). The second author (AB) has attempted to locate the original material described by Mayer but without success.
