Notogynaphallia is a genus of land planarians 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, not occupying the dorsum. The copulatory apparatus lacks a permanent penis, i. e., the penis is formed during copulation by folds in the male cavity. The female cavity is irregular and narrow and the ovovitelline ducts join each other behind it. [1]

Several species formerly placed in Notogynaphallia are currently placed in the genera Imbira and Luteostriata.

Etymology

The name Notogynaphallia comes from Greek νότος (back) + γυνή (female) + (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.[2]

Species

There are eight species assigned to the genus Notogynaphallia:

  • Notogynaphallia biseminalis (Riester, 1938)
  • Notogynaphallia froehlichae Ogren & Kawakatsu, 1990
  • Notogynaphallia modesta (von Graff, 1899)
  • Notogynaphallia mourei (Froehlich, 1956)
  • Notogynaphallia parca (E. M. Froehlich, 1955)
  • Notogynaphallia plumbea (Froehlich, 1956)
  • Notogynaphallia sexstriata (Graff, 1899)
  • Notogynaphallia nawei Negrete, Leal-Zanchet & Brusa, 2015

Also, there are some species currently considered incertae sedis:

  • Notogynaphallia andina (Hyman, 1962)
  • Notogynaphallia atra (Schultze & Müller, 1857)
  • Notogynaphallia garua (du Bois-Reymond Marcus, 1951)
  • Notogynaphallia quinquestriata (Hyman, 1962)
