32557B3CFFA9A650FF64FD5E42761E9D.taxon	etymology	Etymology. The new species name uniplicata is from the combination of the Latin words uni, meaning ‘ one’ and plica, meaning ‘ fold or ridge’, alluding to the single oblique ridge on the carapace.	en	Kim, Sung-Hyun, Lee, Chang-Mok (2021): Diastylis uniplicata sp. nov. (Crustacea: Cumacea: Diastylidae) a new Korean cumacean. Zootaxa 4941 (3): 443-450, DOI: 10.11646/zootaxa.4941.3.9
32557B3CFFA9A650FF64FD5E42761E9D.taxon	discussion	Remarks. This new species Diastylis uniplicata sp. nov. has a unique combination of characteristics: carapace surface smooth, with a transverse ridge on frontal lobe; both sides of carapace with a pair of oblique ridges beginning near antero-lateral corner, running upward and connecting to the dorsal median carina; telson 1.7 times as long as pleonite 6, with 5 – 6 simple setae laterally. The most similar species are D. antillensis Sars, 1873 and D. planifrons Calman, 1912, which have a pair of oblique ridges beginning near the antero-lateral corner and running upward. These species, however, lack a transverse ridge on frontal lobe of carapace. Also, oblique ridges on the carapace in D. antillensis and D. planifrons are W-shaped in dorsal view, compared C-shaped in D. uniplicata sp. nov.. Depth. 2 m.	en	Kim, Sung-Hyun, Lee, Chang-Mok (2021): Diastylis uniplicata sp. nov. (Crustacea: Cumacea: Diastylidae) a new Korean cumacean. Zootaxa 4941 (3): 443-450, DOI: 10.11646/zootaxa.4941.3.9
