Abstract

Setarches longimanus (Alcock 1894), in the family Scorpaenidae, was collected from Busan and the coastal waters of Jeju Island, Korea, in January and November 2014, respectively. Two specimens are characterized by XI, 10 dorsal fin rays; 19–21 pectoral fin rays; III, 5 anal fin rays; a second preopercular spine much shorter than the first and third; and an interorbital width 11.3 %–11.6 % of the standard length. We also analyzed 587 base pairs of the mitochondrial DNA cytochrome c oxidase subunit I sequences in order to confirm the taxonomic status of the specimen. As a result, the sequences of our specimen almost corresponded to those of Chinese S. longimanus (genetic distance, d = 0.005), but considerably differed from those of S. guentheri (d = 0.120–0.124). We propose the new Korean names “Ma-su-gam-peng-sok” for the genus Setarches, and “Bul-geun-ma-su-gam-peng” for the species S. longimanus.

Keywords: Setarches longimanus; New record; Scorpaenidae; Jeju Island; Korean fauna

Background

The family Scorpaenidae, in the suborder Scorpaenoidei, contains 418 species and 56 genera throughout the world, with 45 species and 17 genera in Korea (Han et al. 2011; Nelson 2006). This family is widely distributed along all coasts of the world, with most species in the Indian and Pacific Oceans (Nelson 2006). The species of Scorpaenidae are characterized by a strong spine and a well-developed ridge on the head, 3–5 preopercular spines, and a dorsal fin that is usually single with a V-shaped notch (Kim et al. 2005). The genus Setarches contains three species throughout the world: Setarches guentheri Johnson, 1862, Setarches longimanus (Alcock, 1894), and Setarches armata (Fowler, 1938), and the former two of which occur in Japan (Froese & Pauly 2015; Nakabo & Kai 2013). However, no occurrence of the genus Setarches has been reported in Korea. In this study, we confirmed that the specimens collected from Busan and the coastal waters of Jeju Island, Korea, were S. longimanus using morphological and molecular methods, and we provide a morphological description of these specimens as the new record based on the specimens (Fig. 1).

Methods

The two specimens belonging to S. longimanus were collected for the first time from Busan and the coastal waters of Jeju Island, Korea, on January and November, 2014, and were fixed in 10 % formalin and preserved in 70 % ethanol. Counts and measurements were made according to the methods of Eschmeyer (Eschmeyer 1965) and Hubbs and Lagler (Hubbs & Lagler 2004) (body parts were measured to the nearest 0.1 mm with Vernier calipers). The number of vertebrae and all fin rays were counted from radiographs (Sehwa Medical System SMS-CM, Korea). The specimens of S. longimanus are deposited at the Ichthyological Laboratory, Pukyong National University (PKU) and Jeollabuk-do Fisheries Research Institute (JBFRI), Korea. Genomic DNA was extracted from muscle tissues using a DNA Extraction Kit (Bioneer Trade Co. LTD, Korea). The specimens were performed using VF2 (5’-TCA ACC AAC CAC AAA GAC ATT GGC AC-3’) and FishR2 (5’-ACT TCA GGG TGA CCG AAG AAT CAG AA-3’) primers, which amplify the mitochondrial DNA cytochrome oxidase subunit I (COI) (Ivanova et al. 2007; Ward et al. 2005). The polymerase chain reaction (PCR), purification, and sequencing used to modify the method of (Ward et al. 2005). The sequences were aligned using ClustalW (Thompson et al. 1994) in BioEdit ver. 7 (Hall 1999). The sequences of S. guentheri (GU225028; GU805018; JF494505; KC015918) and S. longimanus (JQ681483; JQ681484) from the National Center for Biological Information database, and Sebastiscus marmoratus (PKU 8813) was used as an outgroup. Genetic distances were calculated using the Kimura two-parameter method (Kimura 1980) in MEGA 5 (Tamura et al. 2011). A neighbor-joining (NJ) tree was constructed with the Kimura two-parameter method (Kimura 1980) and 10,000 bootstrap replications using MEGA 5 (Tamura et al. 2011).

Coloration

When fresh, the body and head are red. The operculum, nape, and pectoral fin base have small dark spots. After fixation in formalin, both the body and head are light yellow, and small dark spots are distributed on them.

Distribution

Busan and Jeju Island in Korea (present study), Japan (Nakabo & Kai 2013), China (Chinese Academy of Fishery Science (CAFS 2007), western Pacific Ocean (Eschmeyer & Collette 1966; Gloerfelt et al. 1984; Kulbicki et al. 1994), southward to Taiwan (Shao et al. 2008), Andaman Sea (Rajan et al. 2011), and Arabian Sea (Nakabo & Kai 2013).

Remarks

The present specimens were collected from Busan and Jeju Island, Korea, and identified as belonging to the genus Setarches, based on the following features: body moderately compressed; body and head are red; head scaleless, except for cheek and behind the eye; maxilla without keel; anterior lower infraorbital spine subequal to the two posterior spines. These specimens were assigned to S. longimanus based on following features: second preopercular spine shorter than the first and third; interorbital width 9–12 % SL (11.3–11.6 % SL in this study) (Nakabo & Kai 2013; Eschmeyer & Collette 1966). When compared with the original description (Alcock 1894), most counts were well corresponded to our specimens (Table 1), but our specimens differed slightly from that of Yamada et al. (2009) in the number of gill rakers, pectoral fin rays and vertebrae (Table 1; Fig. 2b). To confirm the taxonomic status of the specimen, we analyzed 587 base pairs of the mitochondrial DNA cytochrome c oxidase subunit I sequences. As a result, the sequences of our specimen (KT189677) almost corresponded to those of Chinese S. longimanus (genetic distance, d = 0.005), but considerably differed from those of S. guentheri (d = 0.120–0.124). Their relationship was also strongly supported by the neighbor joining tree with high bootstrap values (Fig. 3). Therefore, these subtle differences in some counts seem to be geographic variations within species. Most of the meristic characters in our specimens corresponded to those of S. guentheri and S. armata, but our specimens differed in their preopercular spines (second spine shorter than the first and third in S. longimanus vs. second spine subequal to or longer than the first and third in S. guentheri vs. second spine longer than third in S. armata) (Nakabo & Kai 2013; Eschmeyer & Collette 1966; Fowler 1938). Our specimens can be distinguished from S. guentheri in its interorbital width (9–12 % SL in S. longimanus vs. 7–9 % SL in S. guentheri) (Eschmeyer & Collette 1966), and from S. armata in its number of gill rakers (2 + 9–10 in S. longimanus vs. 6 + 12 in S. armata) (Yamada et al. 2009; Fowler 1938). We propose the new Korean genus name “Ma-su-gam-peng-sok”for the genus Setarches, and the Korean name of S. longimanus was already proposed by Yamada et al. (2009) as “Bul-geun-ma-su-gam-peng”, we followed the name for the species.

Conclusions

The two specimens belonging to S. longimanus were collected for the first time from Busan and the coastal waters of Jeju Island, Korea, on January and November, 2014. These specimens were assigned to S. longimanus based on following features: second preopercular spine shorter than the first and third; interorbital width 9–12 % SL (11.3–11.6 % SL in this study) An analysis of 562 base pair sequences of mitochondrial DNA cytochrome c oxidase subunit I showed that the sequences of our specimen (KT189677) almost corresponded to those of Chinese S. longimanus (genetic distance, d = 0.005), but considerably differed from those of S. guentheri (d = 0.120–0.124).
