Zeus Pencil Wrasse

description

Barcode DNA sequence. A 652 - nucleotide sequence of the segment of the mitochondrial COI gene used for barcoding by the BOLD informatics database (Ratnasingham & Hebert 2007) was obtained for the holotype. Following the database management recommendation of the BOLD, the sequence of the holotype (GenBank accession number KJ 591656) is presented here as well: CCTTTATCTAGTATTCGGTGCCTGAGCTGGGATGGTGGGCACAGCCCTAAGCCTGCTCATCCGGGC TGAGCTTAGCCAGCCCGGCGCTCTCCTCGGAGACGACCAAATTTATAACGTAATCCCACGCCTTCG TAATAATCTTCTTTATAGTAATACCAATTATAATCGGCGGGTTCGGAAACTGATTAATTCCCTTAATGA TTGGGGCCCCCGACATGGCCTTCCCTCGAATAAATAACATAAGCTTCTGGCTTCTTCCTCCGTCTTT CCTTCTTCTCCTCGCCTCGTCAGGCGTAGAAGCAGGGGCTGGCACTGGGTGAACAGTTTACCCTCC CCTAGCTGGTAATCTTGCCCACGCAGGGGCCTCTGTAGACCTCACTATCTTCTCCCTTCACTTGGCA GGTATTTCTTCAATCCTGGGAGCAATCAACTTTATTACTACCATTATTAACATGAAACCCCCTGCTAT TTC TCAGTACCAAACACCTCTCTTTGTATGAGCCGTTTTAATTACAGCAGTCCTCCTCCTTCTCTCG CTGCCCGTTCTTGCTGCCGGCATCACAATGCTTCTAACTGATCGTAACCTCAACACCACCTTCTTTG ACCCTGCTGGCGGAGGTGACCCCATTCTTTATCAACATCTC Comparisons. Among the Pseudojuloides, P. zeus most closely resembles P. mesostigma in marking patterns and the very slender shape. The body depth is less than 18 % SL for the two spe

Description. Dorsal-fin rays IX, 11; anal-fin rays III, 12; all soft dorsal and anal segmented rays branched, last split to base; pectoral-fin rays 13 – 14 (13), the first rudimentary, the second unbranched; pelvic rays I, 5; principal caudal rays 14, the upper and lower unbranched, one additional segmented ray and 3 - 4 visible unsegmented procurrent rays upper and lower; pored lateral-line scales 27 (+ 1 on caudal-fin base); gill rakers 14 (14). Body very elongate, the depth 5.65 (5.75) in SL, and only slightly compressed, the width 1.55 (1.4) in depth; head length 3.15 (3.15) in SL; dorsal profile of head nearly straight on snout, forming low angle of about 20 ° to horizontal axis of body, and slightly convex on nape; snout sharply pointed, its length 3.6 (3.5) in head length; orbit diameter 4.7 (4.85) in head length; interorbital space broadly convex, the least bony width 4.55 (5.1) in head length; caudal peduncle short and narrow, the least depth 3.5 (3.6) in head length, caudal-peduncle length 3.15 (2.8) in head length.

diagnosis

Diagnosis. Dorsal-fin rays IX, 11; anal-fin rays III, 12; pectoral-fin rays 13 – 14 (13); lateral-line scales 27 (+ 1 on tail), 1.5 scales above anterior lateral line to dorsal-fin base; no scales on head; gill rakers 14; a single pair of large, forward projecting canine teeth anteriorly in each jaw, the lowers fitting between uppers when mouth closed; few irregular short pointed but flattened teeth on each side of upper and lower jaws, no canine posteriorly at corner of mouth; very elongate body, body depth 5.65 – 5.75 in SL; only slightly compressed, body width 1.4 – 1.55 in depth; caudal fin slightly rounded; terminal-phase male in life with yellow-green head and body, two prominent jagged-edged iridescent blue stripes along sides of body, a yellow spinous dorsal fin, a large black spot at base of mid-dorsal fin, and a mostly black caudal fin.
