🔬 Taxonomy
🐟 Physical Description
Dorsal spines (total): 0; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 11. Diagnosis: Doumea reidi is distinguished from its congeners, except D. chappuisi and D. stilicauda, by having the dorsolateral and ventrolateral vertebral processes extending through the dermis to form longitudinal bony ridges from the base of the adipose fin posteriorly to the caudal-fin base and from slightly posterior of the anal-fin origin to the caudal-fin base; the exposed processes are in the shape of longitudinal bars with slightly corrugated surfaces that together form an irregular longitudinal ridge . Doumea reidi differs from differs from D. chappuisi in having caudal-peduncle length 31% of standard length, vs. 22-29%; the posterior extent of the adpressed pelvic fin in specimens over 90 mm extending distinctly beyond anterior limit of the anal fin, vs. falling short of that point; the anterior extent of the exposed vertebral processes along the ventral surface of the body extending to the area lateral to the anal-fin base, vs. extending to slightly posterior of pelvic-fin origin; and the pigmentation pattern of the dorsal surface of the unbranched rays of the pectoral and pelvic fins with a series of irregular dark spots against a lighter background, vs. uniformly pigmented . Doumea reidi differs from D. stilicauda in predorsal length 33% of standard length, vs. 27-30%; head length 18% of standard length, vs. 15-17%; caudal-peduncle length 31% of standard length, vs. 35-41%; and caudal-peduncle depth 11.8 times in caudal-peduncle length, vs. 19.6-25.8 times . : elongated.
