TL;DR: Although E. abyssicola from the canyon mostly agree with previous descriptions, their outer orbital spines pointed forward and not outwards as in the original description are presently unknown and will require genetic analysis to be clarified.
Abstract: Ethusina abyssicola Smith, 1884 (Decapoda, Ethusidae) belongs to Ethusidae, a family of small and deep-sea crabs adapted to carrying objects on their backs for camouflage Ethusina abyssicola is the only species of that genus occurring in the West Atlantic, is distributed from New England, USA to Cape Frio, Brazil, and is one of the best adapted brachyuran crabs to inhabit deep water (up to 5046 m) We reported herein E abyssicola in the deep and under-explored ‘Mar del Plata Canyon’ (38°01′S, 53°39′W), Argentina The specimens were taken at 2934 m, which represents the greatest depth record for any brachyuran crab below 25°S in the southwestern Atlantic Although E abyssicola from the canyon mostly agree with previous descriptions, their outer orbital spines pointed forward and not outwards as in the original description The significance of this difference is presently unknown and will require genetic analysis to be clarified

TL;DR: The phylogenetic relationships between 10 of 13 genera of crabs from the superfamily Dorippoidea were investigated using mitochondrial 16S rRNA, 12S r RNA and cytochrome c oxidase subunit I gene sequences to support the division of Dorippidae and Ethusidae as monophyletic families within the DorippOidea.
Abstract: The phylogenetic relationships between 10 of 13 genera of crabs from the superfamily Dorippoidea were investigated using mitochondrial 16S rRNA, 12S rRNA and cytochrome c oxidase subunit I gene sequences. The resultant phylogenetic trees based on the three molecular markers support the division of Dorippidae and Ethusidae as monophyletic families within the Dorippoidea. The inferred inter-generic relationships within Dorippidae concur with groupings based on the overall morphology of the carapace and structures of the male first pleopods.
