The genus Odilia was originally described with synlophe oriented from right-ventral line to left-dorsal line; hypertrophied lateral ridges; left-dorsal ridge almost as long as left-ventral ridge tending to the formation of a small careen. Gradient in ridge size latero-median or ridges very numerous and of similar size (Durette-Desset, 1971). Based on the variability of the synlophe and the presence or absence of a careen, Durette-Desset and Digiani (2015) seperated the species originally described as genus Odilia into 8 genera:
Odilia (sensu stricto) Durette-Desset, 2013
Hughjonestrongylus Digiani & Durette-Desset, 2014
Parasabanema Smales & Heinrich, 2010
Hasegawanema Durette-Desset & Digiani, 2015
Chisholmia Durette-Desset & Digiani, 2015
Lesleyella Durette-Desset & Digiani, 2015
Sanduanensis Durette-Desset & Digiani, 2015
Equilophos Durette-Desset & Digiani, 2015
Characteristics of genus Odilia:
Synlophe with 14-18 ridges in both sexes. Ridges continuous (except type species with ventral ridges discontinuous). Careen supported by two medium-sized ridges, at least in proximal part of body, with ventral ridge longer. Ridge 1' is the left ridge. Ridges unequal in size, median to small. Careen, ridges associated with the right ridge, and ventral-left-ventral ridges, largest. Other ridges (mid-dorsal, right-ventral) smaller. Presence of two minute ridges or a gap dorsally adjacent to largest left-ventral ridges (except type species). Cuticular dilatations situated on left-dorsal and right-ventral quadrants. Axis (es) of orientation oblique.
