Type locality. Little Bahamas Bank.

Etymology. The species is named after Hiro’omi Uchida, who recognize the new species based on descriptions of the specimens from The Bahamas (mis)identified by McMurrich as Halcurias pilatus .

Short description. Halcurias with column 49.4–73.0 mm height and 26.1–38.3 mm diameter in preserved specimens; distal column with nematocyst batteries with only basitrichs. Tentacles 55–70, smooth, tapering, longer than diameter of oral disc, 11–18.5 mm length in preserved specimens. Ten pairs of perfect mesenteries; microcnemes growing in endocoels only in distal-most column. Living specimens with whitish column, long tapering whitish-translucent tentacles and bright orange mouth elevated on hypostome ( Fig. 2 View FIGURE 2 ).

A detailed description of H. uchidai sp. nov. including images of histological characters, cnidae and cnidae measures is available in Rodríguez et al. 2013 (pag. 5–6, figs. 1, 6–8, table 1) under the name Halcurias mcmurrichi .

Natural history and geographic and bathymetric distribution. Halcurias uchidai sp. nov. is widely distributed in deep waters (282–619 m depth) off the northwestern Atlantic, along the northern Gulf of Mexico, the Florida Strait and the Little Bahamas Bank lithoherms, and to the northeastern mid-Atlantic canyons off the US coast (Baltimore Canyon) ( Fig. 1 View FIGURE 1 ). It has been found living in soft bottoms or attached to hard substrate among deep-sea communities of Desmophyllum Ehrenberg, 1834 (former Lophelia Milne Edwards & Haime, 1849 ; see Hoeksema & Cairns 2022) in the Gulf of Mexico.
