Godzilliognomus schrami, a new species of Remipedia (Crustacea) from Eleuthera, Bahamas

Abstract

Godzilliognomus schrami, a new species of the crustacean class Remipedia, Yager, 1981 is the second species assigned to the genus. The new species, with an average body length of 6.8 mm, was collected from an anchialine cave on the Bahamian island of Eleuthera. Godzilliognomus schrami can be distinguished from the other species in the genus, Godzilliognomus frondosus Yager, 1989 by narrower and less trapezoidal tergites, frontal filaments that differ regarding the shape and insertion of the medial process, and dorsal antennular rami composed of only ten segments.

Phylogenetic analysis and systematic revision of Remipedia (Nectiopoda) from Bayesian analysis of molecular data

“…Secondly, we performed a pre-alignment with MUSCLE (Edgar, 2004) with default parameters. Subsequently, the pre-aligned 16S matrix was realigned manually based on the information for secondary structure of A. franciscana from the European ribosomal RNA database (Wuyts et al, 2004) (for descriptions and discussions of methods see Kjer, 1995;Kjer et al, 2007;Koenemann et al, 2010). Finally, the 16S sequence of A. franciscana was removed again from the alignment before analyzing the data.…”

In addition, several analyses also place remipedes, in some cases together with cephalocarids, in various relationships to hexapods, including collembolans (Cook et al, 2005), diplurans (Carapelli et al, 2007;Koenemann et al, 2010), and all Hexapoda (Regier et al, 2010;Stemme et al, 2012;von Reumont et al, 2012) (for a detailed overview see Jenner, 2010).…”

“…The highest abundance and diversity is in the greater Caribbean region including the Bahamas, the Yucatán Peninsula, Cuba, the Dominican Republic, and the Turks and Caicos Islands. As the center of biodiversity, the Bahamas and the Turks and Caicos Islands have two endemic families according to the currently accepted systematics of the group: (1) Godzilliidae, composed of three genera and six species (Godzillius robustus Schram et al, 1986; Godzillius fuchsi Gonzalez et al, 2013; Godzilliognomus frondosus Yager, 1989; Godzilliognomus schrami Iliffe et al, 2010;Pleomothra apletocheles Yager, 1989; and Pleomothra fragilis Koenemann et al, 2008); and (2) the monotypic Micropacteridae with Micropacter yagerae Koenemann et al, 2007a from the Turks and Caicos.…”

Global Biodiversity and Phylogenetic Evaluation of Remipedia (Crustacea)

“…This region has two endemic families ( Figure 4 ). Godzilliidae consists of five described species: Godzillius robustus Schram et al, 1986 [14] , Godzilliognomus frondosus Yager, 1989 [45] , Godzilliognomus schrami Iliffe et al, 2010 [51] , Pleomothra apletocheles Yager, 1989 [46] and Pleomothra fragilis Koenemann et al, 2008 [52] . The monotypic Micropacteridae, with Micropacter yagerae Koenemann et al, 2007 [45] , is exclusively known from the Turks and Caicos Islands.…”
