Amphiura ungulata paper in ZOOTAXA
Colleagues Sabine Stöhr and Øydis Alme have published their study of Amphiura ungulata In a recent issue of Zootaxa (http://dx.doi.org/10.11646/zootaxa.3994.3.6). This West African brittle star has an unusual development of the arms and looks somewhat strange in the juvenile condition.
The brittle stars are a fascinating group of animals with about 2000 known species. Quite a few species have been identified from the MIWA material and we are trying to compare the African shelf fauna with that of the northern Atlantic. Initial DNA-barcoding has returned some puzzling results and we needed another look on some of the problematic individuals. Fortunately, two researchers with very special knowledge of the brittle stars were able to join us in an identification workshop during the last week of November.
Øyidis Alme did her master study on brittle stars and she was joined by Sabine Stöhr from the Natural History Museum of Stockholm for a three days session over the microscopes. Sabine is a respected specialist on the brittle stars and maintains The World Ophiuroidea Database:

The crustacea work-group focused particularly on crabs and shrimps. Some of the hermit crabs, a particularly difficult group, were also identified to species. A few species of squat lobsters, slipper lobsters, and five species of mantis shrimp were also identified. Three 95 sample plates were prepared for DNA-barcoding.
The mollusca work-group identified more than 200 species of snails (Gastropoda) in the material. They took 1763 digital images and prepared 606 lots for the catalogued museum collection. At present, one sample plate has been prepared for DNA-barcoding.
A species of bristle worms (Polychaeta) in a genus that has not previously been found in West Africa.
The workshop identified about 140 species of Polychaeta.At least 12 of the species are clearly new to science. Five genera that have not been recoded from African waters were also identified. 385 specimens were selected for DNA-barcoding.
Sakaila africana was recognized as a new species by Raymond B. Manning and L.B. Holthuis in 1981. Their publication in The Smithsonian Contributions to Zoology is an important source to the identification of West African crabs. An electronic version of the publication is available on this link. Our workshop found Sakaila africana in samples from Guinea Conakry.
