Introduction

One genus of 13 species, Sternostylus, differs from Chirostylidae in having thoracic sternite 3 anteromedially produced and evenly sloping anterodorsally with a pair of spines directly behind the anterior margin, maxillipeds 3 adjacent and the dactyli of the pereopods 2–4 ending in an indistinctly demarcated corneous spine (Baba et al. 2018; Schnabel 2020).
