Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 9; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 11; गुदा कांटा: 3; ऐनल सौफट रेज़: 9; जानवरों की रीड़ का जोड़: 25. This species is distinguished by the following characters: pored lateral-line scales 15 + 5-6; gill rakers on 1st branchial arch 13-14; body depth 3.1-3.2 in SL; head length 3.1-3.2 in SL; snout length 3.8-3.9 in HL; eye diameter 4.2-4.4 in HL; interorbital width 4.2-4.4 in HL; least depth of caudal peduncle 2.2-2.4 in HL; caudal-peduncle length 1.8 in HL; dorsal fin of both sexes without elongate filamentous rays; longest dorsal-fin soft ray of TP male 4.3-4.4 in SL; pelvic fin length 1.6-1.8 in HL; caudal fin of both sexes slightly rounded (truncate in preserved specimens); maximum size to at least 49.3 mm SL; color of TP males generally orange on head and anterior body, grading to reddish or purplish posteriorly (except broad, purple-edged, median orange zone); head and body pink ventrally; stripe pattern purple-to-reddish stripes and bands on head and body with 2 primary stripes expanded and diffuse on posterior half of body; dorsal and anal fins mainly burgundy red to purplish with yellow-orange sections anteriorly on dorsal fin and posteriorly, and narrow blue outer margins; caudal fin mainly blue to purple with broad outer margin of yellow; pelvic fins purple to burgundy red; pectoral fins translucent; peak nuptial-display pattern features a large white patch behind pectoral fin, linked dorsally with tapered stripe of neon blue at level of anterior lateral line, continuing to caudal-fin base (Ref. 107895).
Generally found on sloping, low profile bottoms with branching hard and soft corals (predominantly Sarcophyton and Xenia) at about 20 m. Observed to be in large mixed aggregations with P. paineorum and P. flavianalis. Also, a number of suspected hybrids (most likely P. alfiani x P. paineorum), with the colors of this species and the filamentous rays of P. paineorum, were also observed in the area. (Ref. 107895).
