Emendation of Cibicides antarcticus (Saidova, 1975) based on molecular, morphological, and ecological data

Shallow water Antarctic cibicidids are traditionally identified as Cibicides refulgens or Cibicidoides lobatulus. However, a recent phylogenetic study based on SSU rDNA sequence data has demonstrated that these Antarctic cibicidids form a wellsupported clade that branches sister to Mediterranean C....

Description
Summary:Shallow water Antarctic cibicidids are traditionally identified as Cibicides refulgens or Cibicidoides lobatulus. However, a recent phylogenetic study based on SSU rDNA sequence data has demonstrated that these Antarctic cibicidids form a wellsupported clade that branches sister to Mediterranean C. refulgens and is only distantly related to C. lobatulus. Based on these DNA sequences, and a detailed scanning electron microscopic examination of material from Explorers Cove (McMurdo Sound), we place Antarctic cibicidids in a separate species Cibicides antarcticus (Saidova, 1975), which is emended here with molecular, morphological, and ecological features.
