Pseudogeoplana
genus of worms
Pseudogeoplana is a genus of land planarians of the subfamily Geoplaninae. It was erected to include species lacking sufficient morphological information to allow them to be classified in the appropriate genus.
Taxonomy
Many land planarian species described during the second half of the 19th century and the first half of the 20th century were classified based solely on external characters. Currently, the land planarian genera are highly based on their internal anatomy, especially the anatomy of the copulatory apparatus. As a result, species with old descriptions that were never redescribed, so that their internal anatomy remains unknown, cannot be assigned to the correct genus. Thus, the genus Pseudogeoplana was erected to temporarily accommodate species of the subfamily Geoplaninae whose anatomy of the copulatory apparatus is still unknown.
The public source identifies “Pseudogeoplana” as genus of worms. This brief keeps that definition visible, then builds a research path around Pseudogeoplana, genus and worms.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Pseudogeoplana”, the useful work is to connect “genus of worms” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 16, 2023. The linked authority identifier is Q18579664. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
