Morphology and Anatomy:

Members of the subfamily Diplolaimellinae of the Monhysteridae are characterized by a double buccal cavity at some point during their juvenile or adult stages, while those in the other subfamily, the Monhysterinae, have a single tapered buccal cavity.

• Medium to long nematodes (0.7-4mm)
• Inner labial sensilla papilliform, outer labial and cephalicsensilla in a single circle
• Amphids circular
• Ocelli present or absent
• Buccal cavity funnel-shaped; posterior chamber with or without denticles
• Pharynx cylindrical
• Ventral glland well-developed
• Tail conoid to subcylindrical
• Caudal glands open via spinneret

Distribution:

Species associated with decapod and peracarid crustaceans found in both limnic and marine environments. (Westerman et al., 2022).

Feeding:

The genera Odontobius, Gammarinema  Monhystrium  and Tripylium are exclusively commensally epibiotic and numerous groups of crustaceans are the most common hosts for free-living nematodes (Holovachov et al., 2011).
