Odontozona edyli Criales & Lemaitre, 2017

( Figures 4 , 5 )

Material examined. Panama, Bocas del Toro: 1 ♂ (cl 3.5 mm), 3 ovigerous ♀ (cl 3.1–3.8 mm), FLMNH UF 44403 , Isla Colón, Punta STRI, lat. 9.34878 / long. -82.26289, in Agaricia rubble, around 2 m depth, coll. M. Leray, F. Michonneau and R. Lasley, 19.v.2016 .

Remarks. Odontozona edyli was described based on a single male holotype from Isla Ceycen, San Bernardo Islands, Caribbean coast of Colombia ( Criales & Lemaitre 2017). The Panamanian material represents the first finding of O. edyli since its original description. The four specimens from Bocas del Toro agree well with the description and illustrations in Criales & Lemaitre (2017), although some differences indicative of intraspecific variation are noteworthy. For instance, in the present specimens, the rostrum is curved upwards and bears eight teeth on its ventral margin ( Fig. 5A, B ), instead of being straight and bearing six ventral teeth, as in the holotype. The insertion pattern of the dorsal teeth is also slightly different from that of the holotype (cf. Fig. 5A, B and Criales & Lemaitre 2017: fig. 2A). Slight differences were also observed in the spiny armature of the carapace and third pereopods, but they all seem to fall within the range of normal intraspecific variation, which is also known in other species of Odontozona ( Saito et al. 2017) . To complement the original description of O. edyli , the thoracic sternum of an ovigerous female from Panama is illustrated in Fig. 5C .

The hitherto unknown colour pattern of O. edyli , which is dominated by bright red and orange colours, is illustrated in Fig. 4 . It appears to be generally similar to that of O. rubra Wicksten, 1982 from the tropical eastern Pacific and O. arbur Saito, Okuno & Anker, 2017 from the Indo-West Pacific, these two species also being morphologically closest to O. edyli ( Criales & Lemaitre 2017) . The general colour of the carapace, third to fifth pereopods, tail fan, as well the configuration of the red bands on the pleon, are similar in these three species. However, the main colour difference between these three species appears to be in the fingers (dactylus and pollex) of the third pereopod chela. In O. edyli , both fingers are mostly red, with only the most proximal portion of the pollex marked with a conspicuous white patch ( Fig. 4 ). In contrast, in O. rubra , both fingers are red, paler proximally, and with conspicuous white fingertips (as in the colour photographs in Kerstitch & Bertsch (2006: 76) and Bertsch & Aguilar Rosas (2016: 125)), whereas in O. arbur , both fingers are entirely white ( Saito et al. 2017: fig. 13A–E).
