• Lateral fields not differentiated.

• Lip region rounded, three lip sectors, inner edge of lips more heavily cuticularised, rounded.

• Six tiny labial sensilla and four cephalic sensilla.

• Buccal cavity wide, triangular cross section, longer than lip region diam.

•  Cheilostom anisomorphic, in lateral view ventral wall longer than dorsal wall, ventrally segmented in posterior part.

• Gymnostom anisomorphic joining cheilostom dorsally to produce an internally protuberant ridge.

• Monodelphic, prodelphic, ovary antidromously reflexed and extending posterior to vulva.

• Oocytes initially in multiple rows then in a single row.

• Postvulval uterine sac present, about 1.5 abd long, mostly filled with sperm and functioning as a spermatheca.

• Vulva opening at 55% of body length, lips slightly protruding with a funnel-like cuticular protrusion anterior to vulva and designated as "vulval sac".

• Tail elongated thread-like, aboutseven anal body diam. long.

• Phasmids difficult to discern, located ca one anal body diam. posterior to anus.
  

Male:

• Monorchic, testis reflexed.
