DISTRIBUTION AND HABITAT: The genus Nilobezzia is known from 74 species from every Region worldwide ( Borkent 2014 ; additional species below). Immatures are present in lakes, grassy wetlands, ponds, salt marshes ( Knausenberger 1987), reservoirs, creeks, and rivers.
TAXONOMIC DISCUSSION: There are 17 species of Nilobezzia known as pupae ( Tables 2–3 View TABLE 2 View TABLE 3 ). Only two species, N. schwarzii and N. mallochi , have abdominal membranous discs (see character 50). Nearly all male pupae have short genital lobes, not extending posteriorly past the base of the terminal processes, reflecting the short, modified male adult genitalia; only those of N. schwarzii have more elongate genital lobes (even though the male adult genitalia doesn't seem disproportionally longer).
Nilobezzia theileri (de Meillon & Wirth) was originally described as a Sphaeromias ( de Meillon & Wirth 1981) but is here considered a member of Nilobezzia as a new combination as follows:
Nilobezzia theileri (de Meillon & Wirth), 1981:552 ( Sphaeromias ). new combination.
The pupa has the diagnostic features of this genus and reexamination of the adult holotype shows that the basal tooth of the claws of the adult female are actually outer and not inner, as described and inaccurately illustrated by de Meillon & Wirth (1981). The adult actually keys to Nilobezzia in the key to the Afrotropical fauna by de Meillon & Wirth (1991).
Elson-Harris (1987) keyed the pupae of six Australian species. Elson-Harris (1990) used the position of L-3-IV ventral to L-1-IV (her lpm ii "in line with" lasm) to distinguish Australian Nilobezzia from Australian Hebetula and Lanatomyia and this feature does indeed work for known Australian taxa.
