“…Gibson 1985;Roe et al 2007), proposed that histological features should not be included as a prerequisite to describe/ redescribe new nemertean fauna and that they instead should only be used to address questions about internal organ systems functionality and evolution. To support this statement, Strand et al (2013) suggested that there is no strong evidence that nemertean identifications are more accurate when based on internal features, rather than in external.…”

“…When establishing the heteronemertean Pseudomicrura afzelii Strand and Sundberg, 2011, these authors proposed a new standard in nemertean species description. It is based on external features and DNA sequences, without examination of internal anatomy by serial histological sections, a methodology that has been traditionally employed in nemertean systematics (e.g., Gibson, 1985). Strand and Sundberg (2011) advocated that description of internal morphology is not only useless in inferring phylogeny (at least within certain subgroups of the phylum, e.g.…”

A new species of heteronemertean with branched proboscis, Gorgonorhynchus albocinctus sp. nov., is described based on the external feature and DNA sequences from a specimen collected subtidally among coral rubbles at a depth of about 6 m in a reef area around Taketomi Island in the Yaeyama Islands, southwestern Japan. It can be classified in the genus because the mode of proboscis branching is dichotomous, rather than alternating laterally. From the two known congeners G. repens Dakin andFordham, 1931 and G. bermudensis Wheeler, 1940, the new species can be differentiated by having a brown body colour with a white band near the tip of the head. The new species is placed in a molecular phylogenetic context with a maximum-likelihood analysis using the nuclear 18S rRNA and 28S RNA genes, as well as the mitochondrial cytochrome c oxidase subunit I gene, together with 20 species of heteronemerteans, for which those sequences were available in the public databases. The results indicate that G. albocinctus is closely related to Cerebratulus leucopsis (Coe, 1901), a species that is supposed to have a non-branched proboscis.

“…Although cladistic validity of Gibson's (1985b) family groupings has been challenged (Schwartz andNorenburg 2001, Sundberg et al 2009), for practical purposes the species belongs to Gibson's (1985b) Group E, in having a branched proboscis; yet it possesses a combination of characters that ex− cludes it from any of the genera within this group.…”

Abstract:A new genus and species of heteronemertean from the Antarctic (Bellingshausen Sea), Oligodendrorhynchus hesperides, is described and illustrated. Some morphological features with major systematic significance are following: the mode of branching of the proboscis and its low number of terminal branches; the lack of horizontal lateral cephalic slits but in their place a pair of shallow epidermal depressions; a gelatinous amorphous con− nective stratum between the outer longitudinal and circular muscle layers; the presence of a rhynchocoelic nerve; isolated fibres of the rhynchocoel circular muscle layer interwoven with bundles of the adjacent body−wall inner longitudinal muscle fibres in the intestinal re− gion. Other anatomical characters which can also be used to distinguish the new taxon from existing heteronemertean species that have a branched proboscis are also discussed.
