s from South America.

Description

The genus ''Notogynaphallia'' is characterized by having a small-to-medium, slender body with nearly parallel margins. The eyes are arranged along the body margins and may or not spread to the dorsum. The copulatory apparatus lacks a permanent penis, i. e., the penis is formed during copulation by folds in the male atrium. The male part of the copulatory apparatus also lacks an ejaculatory duct, so that the prostatic vesicle opens directly into the male atrium. The female atrium is usually irregular and narrow and the ovovitelline ducts join each other behind it.

Etymology

The name ''Notogynaphallia'' comes from Greek ''νότος'' (back) + ''γυνή'' (female) + ''ἀ'' (without) + ''φαλλός'' (phallus, penis), i.e., "dorsal female without penis", referring to ovovitelline ducts entering the female atrium dorsally and the absence of a permanent penis.
