Title

A global revision of Oplophoroidea (Caridea: Decapoda) with a novel approach for visualizing genetic differences between species

Abstract

We present the first comprehensive phylogenetic study of the global fauna of the superfamily Oplophoroidea (including all 70 valid species), based on nine molecular markers and 111 morphological characters (including six multistate characters). In this study, we developed a novel approach for assessing and visualizing single- and multigene relative genetic distances (RGD) between species, complementing traditional phylogenetic trees and providing additional support for taxonomic conclusions. While both morphological and molecular phylogenetic trees of Oplophoroidea were largely congruent, the molecular trees were better resolved at most nodes. Based on molecular trees and RGD plots, we confirmed the existence of three families and proposed three new genera within the former Systellaspis, diagnosed them, and provided a key for identifying all genera and species of Oplophoroidea. We were unable to definitively confirm or reject the monophyly of Acanthephyra and Meningodora and, therefore, retained their current status pending further multigene analyses. We also observed a low level of external morphological diversity within Oplophoroidea, likely due to the relatively homogeneous habitats and similar ecological pressures they experience. Additionally, we identified two groups of co-evolving characters, discussed evolutionary trends, and examined behavioral adaptations that contribute to the evolutionary success of these species in the pelagic environment.
