Treatment

Colurostylis longicauda Jones, 1963: 69 –71, Figs. 302–312.— Gerken & Lörz, 2007: 38.

Material examined. None.

Diagnosis. Female and subadult male. Carapace without ridges, anterolateral angle serrate. Pseudorostrum blunt. Eyelobe with lenses. Antennule peduncle of 3 articles. Uropod peduncles longer than pleonites 4–6 together, exopod longer than endopod.

Adult male. Only known specimen incomplete, comprising pereonite 3 to telson , carapace and pereonites 1–2 missing. Telson without subterminal setae.

Remarks. Colurostylis longicauda is most similar to C. castlepointensis and C. pseudocuma . Colurostylis longicauda is the only species of Colurostylis with a serrate anterolateral corner on the carapace, although it is possible that the adult male is lacking the serrate anterolateral corner. In addition, it is unique in the genus in the length of the uropods, with the peduncles longer than pleonites 4–6 together.
