Wittman (fcn. 28). Remarks . The morphological characters of the present specimens agree well with the original description by Heard & Spotte (1991) . Rostrum ( Fig. 63A–G ) straight, or distally slightly upcurved, short, just overreaching basal segment of antennular peduncle in larger specimens, shorter in smaller specimens; dorsal lamina developed, with 2– 6 dorsal teeth at equal distances, proximalmost tooth postorbital in larger specimens; ventral lamina slightly concave with small subdistal tooth in large specimens or without teeth in small specimens. Antennal spine small ( Fig. 63A, C–G ); hepatic spine ( Fig. 63A–G ) slightly more robust, situated slightly below level of antennular spine, directed forward. Third abdominal segment not produced posteriorly. Telson with 2 pairs of dorsal spines at about 0.6 and 0.75 of telson length; lateral pair of distal spines of same size as dorsal spines; posterior margin of telson ( Fig. 63H ) without median process in present material while present in type-material. Basal segment of antennular peduncle with distolateral tooth, without additional teeth on anterior margin. Maxilla endite not bilobed. Ischiomerus of third maxilliped without distomedial mobile spine; with rudimentary arthrobranch. Second pereiopods equal or subequal, lacking teeth on cutting edges of fingers; fingers slender, about as long as palm, dactylus without longitudinal carina. Ambulatory pereiopods slender, with propodi straight, without spines on flexor margin except for distoventral pair, occasionally a subdistal spine is present on the ventral margin ( Fig. 63J ); dactyli ( Fig. 63K ) usually simple, seldom biunguiculate with small accessory tooth ( Fig. 63J ); unguis about two thirds of corpus length, delineation between corpus and unguis indistinct ( Fig. 63J, K ). Exopod of uropod with very small distolateral tooth flanked by distinct mobile spine ( Fig. 63I ). FIGURE 63 . Periclimenes patae Heard & Spotte, 1991 .

Scale bars: A, B=2.0 mm; C–G=1.0 mm; H–K=0.125 mm. Ecology . Lives in association with shallow-water octocorals: Antillogorgia americana (Gmelin, 1791) (cf. Heard & Spotte 1997 as Pseudopterogorgia americana ); Plexaurella sp. ( De Grave & Anker 2017 ). Herein recorded for the first time from: E. tourneforti ; P. porosa ; G. ventalina ; P. citrina ; and the antipatharian A. caribbeana . Distribution . Known from scattered locations in the tropical western Atlantic: Florida Keys , Turks and Caicos Islands ( Heard & Spotte 1991 ); Caribbean coast of Panama ( De Grave & Anker 2017 ). Known to occur in depths between 1 and 12 m . Previously recorded from Curaçao by Horká et al . (2016) .
