(2016) Fitzhugh 1989 Capa et al. 2019  Taxon discussion   Anamobaeawas placed in synonymy with  Hypsicomusby Augener (1925)and defended by Hartman (1959). However, Perkins (1984)recognised  Anamobaea, stating that  A. orstediihas dorsal and ventral basal flanges (as  Notaulax), not present in  Hypsicomus.   Anamobaea,  Hypsicomusand  Notaulaxform part of a well-defined clade, being  Anamobaeaplesiomorphic to  Notaulaxand  Hypsicomus, the latter two genera being sister taxa, based on the common occurrence of radiolar flanges ( Fitzhugh 1989). In a posterior analysis, the three genera were also nested together, but  Hypsicomusresulted in being plesiomorphic to  Anamobaeaand  Notaulax( Nogueira et al. 2010).   Anamobaeais represented by two species worldwide that have been only reported in dead coral masses (bioclaustration). Eight species of  Notaulaxare known to bioclaustrate into coral masses as well ( Nishi et al. 2017,  Tovar-Hernandezet al. 2020). It is unknown where the substrate of  Hypsicomus stichophthalmosGrube, 1863 ( Grube 1863) was found. Major differences amongst  Anamobaea,  Hypsicomusand  Notaulaxare the following:  Hypsicomushas two pairs of accessory, auriculate lamellae, absent in  Anamobaea.  Anamobaeaand  Hypsicomushave chaetae of collar arranged in a small bunch, whereas in  Notaulax, collar chaetal arrangement may be longitudinal, oblique, L-shaped, J-shaped or C-shaped. Members of  Anamobaeado not present radiolar flanges, but these structures are common in  Hypsicomusand  Notaulax, amongst other differences (Table 1). The present definition primarily follows Fitzhugh (1989)and Capa et al. (2019), except for the following: the specimens here examined have 12-16 vacuolated cells in cross section at the base (four or more vacuolated cells in Fitzhugh (1989)and Capa et al. (2019)); the anterior peristomial ring is high, with rounded margin (low, of even height in in Fitzhugh 1989and Capa et al. 2019); dorsal collar margins are not fused to faecal groove (fused to faecal groove in Capa et al. 2019); chaetae form a collar arranged in a small bundle (arrangement not described in Fitzhugh 1989or Capa et al. 2019); mucros of paleate chaetae in abdominal chaetigers are dentate (mucros not described in Fitzhugh 1989and Capa et al. 2019), those mucros from anterior abdominal segments are short (as long as paleae width) while those from posterior abdominal segments are long (longer than three times the width of paleae). Additional features related to radiolar ocelli were based on Bok et al. (2016).
