Materials

Type status: Other material. Occurrence: catalogNumber: CZAP-052; recordedBy: G. da Silva, D. Costa; individualCount: 1; Location: locality: Seixas Beach; verbatimDepth: 1.5 m

Distribution

Red Sea, Mediterranean Sea, Greece, Italy, Atlantic coast of France to Senegal, Cape Verde Archipelago, Brazilian coast ( Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas States), Caribbean Sea, Jamaica, Puerto Rico, Gulf of Mexico, United States of America (Florida), Pacific Ocean, Japan, tropical Indo-West Pacific, Samoa, Tonga and Sri Lanka ( Amaral et al. 2013, DeAssis et al. 2012, Costa and Christoffersen 2016, Costa et al. 2008, Costa et al. 2017, Read and Fauchald 2020m).

Distribution in Paraíba: Seixas Beach ( Costa et al. 2008, Costa et al. 2017, Costa and Christoffersen 2016; and this study).

Notes

Found on the rhodoliths surface.

Remarks: This species already has been recorded for the northeast Brazilian ( Amaral et al. 2013, Costa et al. 2017) and confirmed with morphological description in previous studies (e.g. Costa et al. 2008, Costa and Christoffersen 2016). Notwithstanding, a molecular identification is required and a systematic analysis comparing the genetic distances amongst the species of this genus. For this moment, we continue to consider it as H. splendida .

Diagnosis

( Costa et al. 2008, Costa and Christoffersen 2016, Imajima 2003, Salazar-Vallejo 2018): Prostomium with four eyes, two papilla-like antennae, facial tubercle, nuchal organs and an incision in posterior end. Anterior proboscis ring smooth, carrying two black points in medium-lateral region and a tubercle in the median-posterior region. First segments with eight pairs of modified cirri ("tentacular cirri") (Fig. 4 b). Parapodia sesquiramous-type (notopodial region reduced to cirri and no chaetae); neuropodia with falcigers and dark aciculae. Neurochaetal blades with two teeth-like processes anteriorly, up to 9 times longer than wide.
