Morphology and Anatomy:

Morphologically quite similar to Epitobrilus; the genus is characterized by:

•  Funnel-shaped stoma with two distinct pockets separated by a narrow canal, each pocket  with sclerotized teeth,
•  Amphids cup-shaped located at the level of the anterior pocket,
•  Female genital system didelphic-amphidelphic with non-muscular vagina,
• Male genital system diorchic with six globular ventromedian supplements and, usually, with micropapillae between the supplements,
• Tail in male and female elongate-conoid, uniformly tapering and ending in a short and tubular spinneret on the blunt tail tip. 
• Features that  vary among species:
  • distance between teeth,
  • length of cephalic setae,
  •  excretory pore and spermatheca present in some species,
  • morphology of the spicules and gubernaculum,
  • position of the sphincter between the vas deferens and the ejaculatory duct
  •  number of micropapillae between male supplements, distance between supplements, distance from the last supplement to the cloacal opening,
  • number of caudal setae
  •  position of the subterminal setae.
