urn:lsid:zoobank.org:act:2B27AD22-D6F8-4CFF-8C68-B9682F6E92FF

Type species: Equilophos polyrhabdote (Mawson, 1961) n. comb.

Hosts: Muridae ( Rodentia ).

Host site: Small intestine.

Distribution: Australia.

Etymology: The genus was named in this way because the ridges are of similar size.

Definition: Heligmonellidae , Nippostrongylinae. Synlophe with 35–36 ridges in both sexes. Ridges continuous. Careen absent. Ridges small, of similar size, except mid-right ridges, minute. Axis of orientation almost subfrontal. Characteristic bursal pattern of type 1–4. Each spicule ending in one tip. SpL/BL: 10–11%.

Other species: Equilophos similis (Smales, 2009) n. comb.
