New North Sea nematodes

In 1888, J.G. de Man published an article about new and poorly known North Sea nematodes, based on material collected from the ‘Kanaal door Walcheren’ and the fortifications of Vlissingen.

In this article he described five new nematode genera including five new species: Halalaimus gracilis, Terschellingia communis, Araeolaimus elegans, Dolicholaimus marioni and Syringolaimus striatocaudatus. Moreover, he erected two new genera to receive two species which Bastian described in 1865: Halichoanolaimus robustus and Hypodontolaimus inaequalis. He also described a number of new species in existing genera: Monohystera oxycerca (now Cylindrotheristus oxycercus), Anoplostoma blanchardi, Eurystoma filiforme (now Eurystomina filiformis) and Spilophora paradoxa (now Spilophorella paradoxa). Additional descriptions were presented regarding the poorly known Monohystera ocellata (now Diplolaimella ocellata), Monohystera parva (now Monhystera parva), Monohystera ambigua (appeared identical to Monhystera disjuncta), Monohystera setosa (now Mesotheristus setosus), Enchelidium marinum (a doubtful species), Anoplostoma spinosum (now Axonolaimus spinosus), Thoracostoma denticaudatum, Symplocostoma longicolle (identicqal to Symplocostoma tenuicolle) and Chromadora nudicapitata.
