Bonaire: RMNH. CRUS.D.58239: 5 specimens, Something Special (Pali Grande), 12°09.696′N 068°17.016′W, 6.xi.2019, depth unknown, scuba diving, on brown gorgonian, collected by Peter Wirtz (fcn. 9) (photo). Remarks. The morphological characters of the present specimens agree well with the original description by Heard & Spotte (1997). Rostrum (Fig. 62A–C) straight, short, just overreaching midlength of basal segment of antennular peduncle in females, not extending midsection in males; dorsal lamina developed, with 4–5 dorsal teeth at equal distances, proximalmost tooth at level of orbital; ventral lamina slightly concave without teeth. Antennal tooth small (Fig. 62A, C); hepatic tooth (Fig. 62A–C) more robust, situated slightly below level of antennular tooth, directed forward. Third abdominal segment not produced posteriorly. Telson (Fig. 62D) with 2 pairs of small dorsal spines at about 0.6 and 0.85 of telson length which is slightly more distally in comparison to described for the type-material; lateral pair of distal spines as small as dorsal spines; posterior margin of telson (Fig. 62E) 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 with endite bilobed. Ischiomerus of third maxilliped without distomedial mobile spine; with rudimentary arthrobranch. Second pereiopods equal or subequal, undifferentiated, 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 one; dactyli (Fig. 62F) simple, not biunguiculate; unguis about 2/3 rd of corpus length, joint between corpus and unguis indistinct. Ecology. The species is primarily associated with shallow water gorgonians: Antillogorgia americana (Gmelin, 1791) (cf. Heard & Spotte 1997 (as Pseudopterogorgia americana); De Grave & Anker, 2017); and Plexaurella cf. grandiflora Verrill, 1912 (cf. De Grave & Anker 2017). The species has also been recorded on sponges (De Grave & Anker 2017). The species is herein recorded from: Pseudoplexaura porosa; Plexaura nina; M. laxa; and E. clavigera for the first time. Distribution. Previously known from two locations in the tropical western Atlantic: Turks and Caicos Islands (Heard & Spotte 1997; Debelius 1999) and Caribbean coast of Panama (De Grave & Anker 2017). Known to occur in depths between 1 and 43 m. Herein recorded for the first time from Bonaire.
