Upeneus nigromarginatus, a new species of goatfish (Perciformes: Mullidae) from the Philippines

The Raffles bulletin of zoology (Impact Factor: 1.02). 10/2014; 62:745-753.

ABSTRACT

The goatfish, Upeneus nigromarginatus new species, is described based on 5 specimens (151–196 mm) purchased at a fish market in Panabo City, Mindanao, Philippines. This species is diagnosed by the following counts and external morphology: dorsal fin rays (VIII, 9–10), pectoral fin rays (16), lateral line scales (36–37), total number of gill rakers (25–26), and anal fin rays (I–II, 6). When compared to congeners, U. nigromarginatus new species has a relatively deeper body (31.1–34.8% in SL vs. <30% in SL), shorter snout (7.1–9.0% in SL vs. >9.6 % in SL), and longer pectoral fin (27.7–29.1% in SL vs. <25 % in SL). Upeneus. nigromarginatus new species, has neither stripes on the body, nor bands on the caudal fin. However, a black band borders the distal edges of both the first and second dorsal fins, and at the posterior edge of the upper lobe of the caudal fin; hence the proposed common name ‘black-margined goatfish’. The posterior edge of the ventral caudal lobe has a white margin. The comparisons of a fragment of the Cytochrome C Oxidase Subunit I (COI; 28 specimens representing 10 Upeneus species) and 34 morphometric parameters (Principle Component Analysis; 56 specimens representing 5 genera and 12 mullid species) supported the description of U. nigromarginatus new species.

    ABSTRACT: Upeneus lombok n. sp. is described from two specimens collected off Lombok, Indonesia, at depths of 54-76 m, and one subadult specimen from the local fish market at Tanjung Luar, Lombok. Four specimens of U. asymmetricus were collected at the same fish market representing the first record of the species since its description from two Philippine Islands in 1954. These two species are compared in detail and with five congeneric species that all share a 7-spined dorsal fin and a high gill-raker count. Upeneus lombok n. sp. differs from all other congeners in having a short snout (snout length 9.0-9.6% SL) combined with a low anal fin (anal-fin height 12-13% SL in adults, 15% in single subadult). The newly recorded U. asymmetricus specimens differ from their types only slightly and all eight specimens together differ from all congeneric species in the combination of 7 dorsal spines, 12-14 pectoral fin rays, 26-28 total gill rakers, short pectoral fins (pectoral-fin length 18-21% SL) and short jaws (upper jaw length 8.7-11% SL). In both species the caudal-fin colour patterns of fresh fish are of diagnostic significance, the only exception being a close similarity between Upeneus lombok n.sp., U. saiab, and U. seychellensis. Additional comparisons with 14 Upeneus species which overlap in distribution or occur in nearby areas are also made. Needs for further taxonomic exploration of the Indonesian-Philippine region and for enhanced attention to the economic and ecological importance of Upeneus species are discussed.
