A new species of Prosorhochmus is described from Belize and Florida based on morphological, reproductive and sequence data. Similar to Prosorhochmus nelsoni (Sanchez, 1973), Prosorhochmus belizeanus sp. nov. is gonochoric and oviparous; all other species of Prosorhochmus are viviparous hermaphrodites. Prosorhochmus belizeanus sp. nov. differs from P. nelsoni by having significantly larger stylets and different arrangement of acidophilic cephalic glands. Sequence divergence between the two is 7… 

Revision of the smiling worms, genera Prosadenoporus Bürger, 1890 and Pantinonemertes Moore and Gibson, 1981 and description of a new species Prosadenoporus floridensis sp. nov. (Prosorhochmidae; Hoplonemertea; Nemertea) from Florida and Belize

The hoplonemertean genera Prosadenoporus Bürger, 1890 and Pantinonemertes Moore and Gibson, 1981 are revised and synonymized based on a morphological re‐evaluation and a new semi‐terrestrial species is described from Belize and Florida.

Systematics and phylogeny of the hoplonemertean genus Diplomma (Nemertea) based on molecular and morphological evidence

A redescription of the poorly known distromatonemertean Diplomma serpentina (Stimpson, 1855), a species that has not been reported since its original description, and comparison of cytochrome c oxidase subunit I gene (COI) sequences indicates that D. serpentina is distributed in Indonesia, the Philippines, and Japan.

Phylogenetic placement of a new hoplonemertean species commensal on ascidians

The hoplonemertean Vieitezia luzmurubeae, previously mistaken as the Mediterranean species Tetrastemma vittigerum (Burger, 1904), is frequently associated with two common species of sea squirt, Phallusia mamillata (Cuvier, 1815) and Ciona intestinalis (Linnaeus, 1767), inside which the nemerteans completes its life cycle.

Resolving a 200-year-old taxonomic conundrum: neotype designation for Cephalothrix linearis (Nemertea: Palaeonemertea) based on a topotype from Bergen, Norway

This paper redescribes C. linearis based on two topotypes from Bergen, one herein designated as the neotype for C.linearis, and tabulated a total of 36 nominal species that are likely the members of the genus; the following five were excluded even though their specific names were originally combined with Cephalothrix.

Feeding rates of the nemertean Prosorhochmus americanus (Hoplonemertea) on two species of gammaridean amphipods

The results and those of other laboratory investigations suggest that nemerteans that prey on amphipods feed at a rate of ∼0.2 prey items nemertean−1 d−1, but under natural conditions this rate may not be obtained because of limited feeding time, longer foraging distances, and emigration of prey from regions of high nEmertean activity.

First Record for Prosorhochmus americanus ( Nemertea , Hoplonemertea ) in Virginia with Notes on its Natural History and Morphology

The viviparous hoplonemertean Prosorhochmus americanus (Gibson et al.) is documented for the first time in Virginia. The nemertean occurs on the north jetty at Rudee Inlet, Virginia Beach, VA in the

A DNA-based description of a new nemertean (phylum Nemertea) species

The question whether anatomy is in fact the best and most efficient basis for phylogeny and classification is posed, which is pragmatically proposed that nemerteans can be described by a combination of external characters and DNA sequences.

Arenogigas armoricus, a New Genus and Species of a Monostiliferous Hoplonemertean (Nemertea) from the North-West Coast of France

A new genus and species of an endobenthic, unusually large eumonostiliferous hoplonemertean, Arenogigas armoricus gen. et sp. nov., is described from an intertidal sandflat in Pouldohan Bay near

Polymorphism hides cryptic species in Oerstedia dorsalis (Nemertea, Hoplonemertea)

It is concluded that O. dorsalis hides different species with geographic resolution, and no diagnostic features in pigmentation or external characters to separate species within this complex are found.

The invention of the pilidium larva in an otherwise perfectly good spiralian phylum Nemertea.

This review is an attempt to examine the pilidium in the context of recent data on development of non-pilidiophoran nemerteans, and speculate about the evolution of pilidial larval development.

Interestingly, Prosorhochmus nelsoni (Sanchez, 1973) is characterized by separate sexes and oviparity, unlike all the other members of the genus, which combine hermaphroditism with ovoviviparity.
