The Diversity and Phylogenetic Relationships of a <i>Chaetopterus</i> Symbiont Community in Djibouti, with Redescription of <i>Chaetopterus djiboutiensis</i> Gravier, 1906 Stat. Nov. (Annelida: Chaetopteridae)

The tubes of polychaetes of the genus <i>Chaetopterus</i> (Annelida: Chaetopteridae) provide habitat for cryptic, symbiotic organisms that are often overlooked when examining diversity. Our study employed molecular phylogenetics to examine the diversity of symbiont species associated wit...

description The tubes of polychaetes of the genus <i>Chaetopterus</i> (Annelida: Chaetopteridae) provide habitat for cryptic, symbiotic organisms that are often overlooked when examining diversity. Our study employed molecular phylogenetics to examine the diversity of symbiont species associated with <i>Chaetopterus djiboutiensis</i> stat. nov., collected from the Gulf of Tadjoura, Djibouti. A total of 15 <i>Chaetopterus</i> hosts and their associated symbionts were collected from nine coastal sites. Four genetic regions were targeted for PCR amplification: the mitochondrial cytochrome oxidase subunit I and 16S rDNA and the nuclear 18S rDNA and Histone H3. <i>Chaetopterus djiboutiensis</i> was redescribed from topotypic material and elevated to species rank, and a neotype specimen was designated. Phylogenetic and morphological analysis confirmed five species associated with <i>C. djiboutiensis</i> in Djibouti: two porcelain crabs, <i>Polyonyx pedalis</i> and <i>Polyonyx socialis</i>; one nudibranch, <i>Tenellia chaetopterana</i>; one fish, <i>Onuxodon</i> sp.; and one amphipod, <i>Leucothoe</i> sp. A. As only the fourth comprehensive study on <i>Chaetopterus</i> symbionts, our study highlights the diversity and community patterns of symbionts associated with these unique tubicolous marine polychaetes.
