I- Genus Odilia Durette-Desset, 1973 ( Fig. 2A )

Type species: Odilia mackerrasae (Mawson, 1961) .

Hosts: Muridae ( Rodentia ).

Host site: Small intestine.

Distribution: Mainland Australia, Tasmania.

Definition: Heligmonellidae , Nippostrongylinae. 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. Characteristic bursal pattern of types 2-2-1, 1-3-1. Dorsal ray divided within proximal half. Each spicule ending in one tip. SpL/BL: 7–16%.

Other species: O. brachybursa (Mawson, 1961) , O. emanuelae (Mawson, 1961) , O. melomyos (Mawson, 1961) , O. tasmaniensis Gibbons & Spratt, 1995 .
