Description

Genus Sternostylus Baba, Ahyong & Schnabel, 2018

[New Japanese name: Tsuno-wara-ebi-zoku]

Remarks. Baba et al. (2018) separated the genus Gastroptychus Caullery, 1896 into two genera. Twelve species were assigned to the new genus Sternostylus based on the shape of the sternite 3, which slopes anteriorly with a pair of spines on the anterior surface, the close placement of the maxilliped 3 coxae and the dactyli of the pereopods 2–4 ending in a clearly demarcated, corneous unguis. Using molecular evidence, Schnabel (2020) showed that Sternostylus is indeed in intermediate position between Kiwaidae and Chirostylidae. Since the establishment of Sternostylus and Sternostylidae by Baba et al. (2018), two new species have been described from the West Pacific region (Schnabel 2020; Dong et al. 2021). Including the present new species, 15 species are now contained in Sternostylus.
