Notogynaphallia
genus of worms
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 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.
Species
There are nine species assigned to the genus Notogynaphallia:
Also, there are some species currently considered incertae sedis:
Several species formerly placed in Notogynaphallia are currently placed in the genera Imbira and Luteostriata.
Begin with the source’s own compact description: “Notogynaphallia” is genus of worms. The dossier treats that line as a proposition to test through Notogynaphallia, genus and worms, not as a finished interpretation.
Why this record matters
The phrase “genus of worms” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 8, 2026. The linked authority identifier is Q11938979. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
