Panay Ponyfish, Photopectoralis panayensis (Kimura & Dunlap 2003)

More Info


Distribution

Off Port Douglas, Queensland. Elsewhere the species occurs in the west Pacific: Philippines. Inhabits soft sediment areas.

Features

Dorsal fin VII, 16; Anal fin III, 14; Vertebrae 24. 
Mouth protruding forward, not downward; teeth small, slender, pointed, uniserial on jaws; lateral line incomplete, ending below base of 14th to 16th dorsal fin soft ray or at anterior caudal peduncle; body deep, 41-51% SL; posterior limb of maxilla long, 21-26% HL; anteroventral profile of lower jaw slightly concave; belly almost wholly scaled.

Remarks

Baranguay Parara Norte, Tigbauan, Iloilo, Panay Island, Philippines

Similar Species

Leiognathus panayensis differs from L. aureus in having a deeper body (41–51% SL vs. 35–45% SL in the latter), long posterior limb of maxilla (21–25% HL vs. 15–23% HL), wholly scaled belly (vs. naked along preanal median keel), and a dark blotch on nape (vs. absent).

Etymology

Sparks et al. (2008) erected the genus Photoplagios for a number of Leiognathid species but Kimura et al. (2008) noted that Equulites was a senior synonym of Photoplagios. Sparks & Chakrabarty (2015) erected the genus Photolateralis for some species previously placed in Equulites.
