Morphology and Anatomy:

Based mainly on description of Copemania darwini:

• Small nematodes; straight or slightly coiled
•  Synlophe for C. darwini symmetrical in relation to frontal axis with 12 prominent cuticular ridges (6 dorsal, 6 ventral). 2 tiny, right lateral ridges. Ridges decreasing slightly in size from left to right on both sides. Right lateral ridges tiny and orientated perpendicularly to body surface
•  Mouth triangular, lips absent; 4 cephalic papillae and two amphids present; buccal capsule tiny, annular;without esophageal tooth;
• Cephalic vesicle present with 15-20 annulations; cervical collar absent;
• Esophagus claviform. Nerve ring in mid-esophageal region; deirid and excretory pore immediately posterior to nerve ring.

Biology and Ecology:

Relationships within the family Nicollinidae are not well-defined.  In Australia, Durette-Desset and Beveridge (1981) hypothesized that the genus Copemania is probably derived from Nicollina and suggested that dasyurid marsupials had acquired the genus by host switching of nematodes already present in monotremes.
