Redescription of some species of Bryozoa described by J. Jullien and L. Calvet in the NE Atlantic
(2015)
Five species described by Jullien and/or Calvet from the NE Atlantic are redescribed and stabilized by typification: Hippothoa amoena, Schizoporella confusa, S. jullieni, S. ovum and Smittia guernei. Three new synonymies are established: Schizoporella jullieni with Hippothoa amoena, S. ovum with Escharina alderi, and Escharella pseudopunctata with Smittia guernei. A new trypostegid genus, Pulpeirina gen. nov., is erected for H. amoena. Three new combinations are introduced.
Sharon gen. nov. is here described to include Asaphes? amoenus Philippi, 1861 comb. nov. from Chile. A redescription of the species is based on the female holotype and material from different geographic locations. Candèze (1891) placed Asaphes amoenus and Parasaphes elegans in the suprageneric group Asaphites. We discuss differences between Sharon gen. nov. and Hemicrepidius Germar, 1839, where Asaphes amoenus was later placed by Blackwelder (1944). Based on morphological characters, Sharon gen. nov. appears to be related to Parasaphes Candèze, 1881, Wynarka Calder, 1986, and Tasmanelater Calder, 1996, all from Australia, suggesting Gondwanan relationships.
A new monospecific genus, Pseudostegopterus gen. nov., endemic to the northwestern region of South Africa, is erected. The type species is described as Pseudospegopterus melonthinoides sp. nov. and is currently known only from male specimens. A provisional dichotomic key of the African Trichiina genera is also provided, in order to facilitate the identification of male specimens to the genus level.
