Description
''Notogynaphallia nawei'' is a small-to-medium-sized land planarian with an elongate body, reaching about in length. The color of the dorsum is black and the dorsal eyes are perceived as a group of very small whitish dots on about the second fourth of the body. The ventral side is dark gray with a thin whitish median longitudinal line along the body.
The species lacks a glandular margin, and the prostatic vesicle is intrabulbar with two regions: a tubular proximal portion and a globose distal portion, with a narrow lumen. The female atrium is tubular distally, but wide proximally.
