Namyhplana

Namyhplana is a genus of marine flatworm belonging to the family Euplanidae.

The genus Namyhplana is distinguished from other Euplanidae by the pharynx being anterior to the mid-body, the presence of cerebral, pre-cerebral and anterior marginal eye spots, a penis papilla, lacking any stylet, horizontally placed on the male copulatory apparatus, and a Lang's vesicle on the female apparatus.

[2] N. henriettae has a ribbon-like body shape that can reach up to 25 mm in length.

Additional distinguishing factors include an absence of tentacles, a pharynx with few folds, independent gonopores, and a curled vagina.

[2] Both the generic and specific names of Namyhplana henriettae are given in honor of Libbie Hyman.
