Description
Description. Based on male Holotype, 3.0 mm. Head.Head eye lobes rounded; eye suboval, very large. Antenna 1 longer than 2; peduncular articles 1 and 2 subequal in length; flagellum shorter than peduncular article 1 and 2 combined with 9 articles. Antenna 2 peduncular article 5 shorter than 4; flagellum subequal in length with peduncular article 5, with 5 articles. Mandible palp article 3 shorter than 2 and about twice length of article 1 with a single distal seta. Maxilliped outer plate tuberculate. Pereon.Gnathopod 1 coxa anterior margin straight to weakly concave, posterior margin convex, basis slender, 4 × as long as broad; carpus slender, posterodistal spine 4 × as long as broad, weakly curved distally; propodus slender, parallel-sided 5 × as long a broad, palm smooth; dactylus short about one sixth length of propodus. Gnathopod 2 coxa subrectangular, basis slender, parallel-sided, a little over 3 × as long as broad, carpus distal margin crenulated; propodus subovoid, lacking mediofacial setal row; palm with a series of flat-topped spines; dactylus elongate, stout, fitting palm. Pereopod 3 coxa subrectangular. Pereopod 4 coxa weakly excavate posteriorally. Pereopods 5–7 basis expanded. Pereopod 7 basis posterior margin weakly saw-toothed.
Pleon.Epimeron 1 posterodistal margin rounded. Epimeron 2 posterior margin with row of setae, posterodistal margin weakly extended. Epimeron 3 posterodistal margin rounded. Uropods 1–3 rami subequal and subequal in length with peduncle. Telson terminally tridentate. Female. Similar to male but gnathopod 2 propodus palm with more accentuated flat topped spines. Remarks.Leucothoe whiteae sp. nov. shows some similarity with L. obuchii White & Reimer (2012 a) from the Ryukyu Islands of Japan, with which it shares the tuberculate maxilliped outer plate, the weakly setiferous mandible palp, the short dactylus of gnathopod 1 and the form of the palm of gnathopod 2. In that species, however, compared with L. whiteae sp. nov. the antennae are shorter and subequal, the basis of gnathopod 1 is medially expanded, gnathopod 2 has a distally narrow carpus and rami of uropod 3 are shorter than the peduncle. Habitat. Amongst alcyoniids.
