“…(B)Hemichordate phylogeny with limited representation of the pterobranchs and enteropneusts, showing the relationships between lineages containing the most commonly studied hemichordates, Ptychodera flava (Ptychoderidae), Saccoglossus kowalevskii (Harrimaniidae) and Rhabdopleura compacta (Pterobranchia), along with the deep sea family Torquaratidae [based on published data (Cameron et al, 2000;Winchell et al, 2002;Cannon et al, 2009;Osborn et al, 2012)]. PRIMER Development 139 (14) placement, and their position as the sister group to the hemichordates and echinoderms remains controversial (Hejnol et al, 2009;Lowe and Pani, 2011).…”

Hemichordates are a deuterostome phylum, the sister group to echinoderms, and closely related to chordates. They have thus been used to gain insights into the origins of deuterostome and chordate body plans. Developmental studies of this group have a long and distinguished history. Recent improvements in animal husbandry, functional tool development and genomic resources have resulted in novel developmental data from several species in this group. In this Primer, we introduce representative hemichordate species with contrasting modes of development and summarize recent findings that are beginning to yield important insights into deuterostome developmental mechanisms.

“…H emichordates occur from intertidal to abyssal depths of the ocean and are important for understanding deuterostome phylogeny [1][2][3] . In particular, hemichordates with their sister group, echinoderms, form Ambulacraria 1 , and provide insights into the deuterostome ancestor.…”

“…The hemichordate group Enteropneusta has recently been revised by the use of morphological and molecular methods (Cameron 2005;Cannon et al 2009). The family Harrimaniidae, to which the new species belongs, is revised by Deland et al (2010).…”

“…Remaining data from Cannon et al (2009) makes it unlikely that the species from Australia is P. koehleri. The species mentioned as Protoglossus (EU728432) is located close to Harrimania (AF236799) in the analysis of Cannon et al (2009) as well as in our analysis. We have also included the sequence of Harrimania kupfferi, previously not sequenced, that clusters as a neighbour of the former (Fig.…”

A new species of the genus Protoglossus is described from the west coast of the Scandinavian Peninsula. It lives buried in clay bottoms below the halocline where the salinity is at least 33-34 psu. Body small, estimated maximal length 1.5 cm. Collar broader than long, with a forward inclination. The thickest part is the collar region where it can be up to 1 mm in diameter. Proboscis colouration light pink to golden yellow; collar white with transversal yellow bands; branchial, hepatic and intestinal regions translucent pale yellow to golden yellow; brown intestine visible through the body wall. Proboscis groove extends through posterior half of proboscis. Nine to 17 pairs of gill openings, the size of the posteriormost successively smaller. It differs from the other European species, Protoglossus koehleri, in colouration, smaller size, fewer gill openings, body shape and proportions. It was sequenced (18S rRNA gene) and clustered within the family Harrimaniidae, with Saxipendium as its closest relative.
