Diagnosis
Modified by Shields et al. (1989) from Humes (1942): Monostiliferous hoplonemerteans living as symbionts (egg predators) on the gills, under the abdomen, on the apodemes, axillae, and in or on the egg masses of decapod crustaceans. Short proboscis, reaching scarcely beyond the posterior end of the muscular portion of the oesophagus. Lateral nerves lie internal to the well-developed submuscular glands. Cephalic glands well developed, with cephalic muscle fibres present. Cerebral organs lacking. Takakura’s duct system present in males. Internal fertilization and oviparity occur commonly. In most species, adult worms occupy, at least temporarily, mucus sheaths secreted and attached to the setae on the pleopods and hairs of endopodites of ovigerous decapods. Embryos hatch as hoplonemertean planuliform larvae.
