Morphology and Anatomy:

In the Molinidae, most species have synlophes with variations of an 18-ridge bilaterally symmetrical system in the cervical region. A sixth species has 26 cervical ridges. Two groups of species of genus Nematodirus are recognized on the basis of synlophe characteristics and other morphological features:

 

 

 

Females:

  • didelphic

  • vulva in posterior 25% of bodyovejector kidney-shaped,

  • tail with caudal spine and tubercles

 

Ref:  Durette-Desset et al, 1981; Durette- Desset and Chabaud, 1981

 

Males:  

  • Caudal bursa with ornamentation over entire ventral surface.
  • Dorsal lobe round. Dorsal ray short. Rays 9 perpendicular to dorsal ray.
  • Spicules 170-290 um long, alate, divided into two processes.
  •  Gubernaculum 70 um long.
  • Genital cone well developed.
