Names used for nemertean genera and species of the world are listed alpha-betically, with their original description citations, synonymy and current taxonomic status. Though many remain inadequately…
The Need for a Standard Approach to Taxonomic Descriptions of Nemerteans
- R. Gibson
- Biology
- 1 February 1985
An evaluation of the systematic significance of several anatomical characters leads to the suggestion that the primitive heteronemertean organization included a proboscis with three muscle layers, a foregut with neither splanchnic muscles nor subepithelial glands, and a blood system not developed into a vascular plexus around the foreGut.
Evolutionary relationships between mono- and polystiliferous hoplonemerteans: Nipponnemertes (Cratenemertidae), a “missing link” genus?

- 2004
It is suggested that ancestral enoplans possessed a rhynchocoel wall containing two muscle layers and a simple “protopolystiliferous” type of proboscis armature, and that this ancestral pool gave rise to two distinct evolutionary lineages, one leading to cratenemertid, group 2 terrestrial and freshwater, and polystilifierous hoplonemerteans, the other to the typical modern monostiliferously forms.
Nemerteans of the Great Barrier Reef: 5. Enopla Hoplonemertea (Monostilifera)
- R. Gibson
- Biology
- 1 July 1982
Three new species of monostiliferous hoplonemerteans from the Great Barrier Reef province of Australia are described and illustrated. These are, with their families indicated in parentheses,…
Further studies on the evolution of land and freshwater nemerteans: generic relationships among the paramonostiliferous taxa
Morphological characteristics of the terrestrial and freshwater paramonostiliferous nemerteans are compared and the possible evolutionary relationships of the plectonemertid genera are discussed and a diagnosis of the family is provided.
The Geonemertes problem (Nemertea)
A re‐examination of all the known species of Geonemertes has shown that two major groups can be distinguished on the basis of morphological characters, and a key to the terrestrial, brackish‐water and marine nemertean species described in the present paper is provided.
Nemerteans of the Great Barrier Reef: 2. Anopla Heteronemertea (Baseodiscidae)
- R. Gibson
- Biology
- 1 February 1981
Nine species of lineid heteronemerteans are recorded from the Great Barrier Reef province of Australia. Six of these are new species, including four new genera, and are fully described and…
Genetic evidence for the occurrence of a cryptic species with the littoral nemerteans Lineus ruber and L. viridis (Nemertea: Anopla)

- 1 April 1995
The low genetic identities found in intrageneric comparisons of species found in this study have been found in other studies on nemerteans and may indicate systematic problems within these groups or other phenomena such as morphological stasis.
