CALLOGOBIUS NIGROMARGINATUS, A NEW SPECIES OF GOBY (PISCES: GOBIIDAE) FROM TAIWAN

Jeng-Ping Chen and Kwang-Tsao Shao

ABSTRACT Callogobius nigromarginatus, was collected from muddy-sand bottom close to a reef flat in Taitung County, southeastern Taiwan. This species has 25–26 lateral scale rows, thus belonging to the group with fewer scale rows as proposed by Goren et al. (1991). Diagnostic characters of this species include: fewer predorsal scales (5), 7–8 transverse scale rows, with posterior oculoscapular pores, three preopercular pores, pelvic fraenum present, and distinctive color pattern (broad stripe on 2nd dorsal and anal fin in adult). A key to all eight species of this low-scale-row group is also presented.

The genus Callogobius Bleeker, 1874 is characterized by having a depressed head with cutaneous papillose ridges; rear nostrils tubular; body elongate; 25–75 scales in the lateral series; pelvic fin small, frenum weak to moderately developed or absent; D.VI-I, 7- 15; A.I 6-13; P. 15-19; 26 or 27 vertebrae; caudal fin lanceolate or rounded. Callogobius has many junior synonyms. Koumans (1953) treated the following four genera as its junior synonyms: Ulcigobius Fowler, 1918, Metagobius Whitley, 1930, Crossogobius Koumans, 1931, and Batracheleotris Fowler, 1938. Mckinney and Lachner (1978a) excluded five nominal species which were originally described in Callogobius and listed 31 nominal species. However, 23 of the 31 species had been included variously in 10 other genera, e.g., Doryptena Snyder, 1908, Macgregorella Seale, 1910, Mucogobius McCulloch, 1912, Gunnamatta Whitley, 1928 and Intonsagobius Herre, 1943, are now treated as junior synonyms of Callogobius; the genus Galera Herre, 1927, preoccupied by Gray in Mammalia, and replaced by Herrea Whitley, 1930 is also a synonym of Callogobius (Eschmeyer, 1990); some other species were mistakenly assigned into the following four valid genera: Drombus Jordan and Seale, 1905, Eleotris Bloch and Schneider, 1801, Gobimorphus Gill, 1863, and Gobius Linnaeus, 1758. After Mckinney and Lachner (1978a) listed 31 Callogobius species, few researchers have dealt with Callogobius. Mckinney and Lachner (1978b) published a new species of C. stellatus. Goren (1978, 1979, 1980) added three species into this genus, namely C. clarki, C. bauchotae, and C. dori. Mckinney and Lachner (1984) described another new species of C. crassus and synonymized five species with C. maculipinnis (Fowler, 1918); combining C. trifasciatus Menon and Chatterjee, 1974, with C. flavobrunneus (Smith, 1958); and C. tutuilae (Jordan and Seale, 1906) with C. sclateri (Steindachner, 1879). The latest new species of this genus, C. amikami was described by Goren et al. (1991) from the Red Sea. In total, before this paper, Callogobius had 30 species in the world. Mckinney and Lachner (1984) pointed out that the following seven species of C. bauchotae, C. centrolepis Weber, 1909, C. crassus, C. flavobrunneus, C. maculipinnis, C. plumatus (Smith, 1959), and C. sclateri appear to form a discrete group within Callogobius, in having a stout-body shape, ctenoid scales, and a reduced number of segmented dorsal fin elements. Goren et al. (1991) also proposed another low-scale-row group (less than 26 rows along the body) with seven species in this genus. There are five species in common between these two groups. Goren et al. (1991) added C. dori and C. amikami into the low-

457 458 BULLETIN OF MARINE SCIENCE, VOL. 66, NO. 2, 2000 scale-row group and deleted C. sclateri and C. flavobrunneus from the stout-body shape group as defined by Mckinney and Lachner (1984). In Taiwan, four species of Callogobius were listed in Chen and Yu (1986), including C. liolepis Koumans, 1931, C. sclateri, C. snelliusi Koumans, 1953, and C. hasseltii (Bleeker, 1851). According to Mckinney and Lachner (1978a, 1984), C. liolepis should be removed from the genus Callogobius; and C. snelliusi is a junior synonym of C. maculipinnis. In book “Fishes of Taiwan”, edited by Shen (1993), Lee (1993) revised gobiid fishes and excluded C. hasseltii from the Taiwanese fish fauna without further explanation. Shao and Chen (1993) added C. okinawae (Snyder, 1908) and Chen et al. (1996) added C. tanegasimae (Snyder, 1908). On 25 January 1994, two specimens of Callogobius were found and collected by the first author (JPC) in a rocky hole from Chengkung, Taitung County, southeastern Taiwan, located on the boundary between reef flat and sand bottom at about 10 m depth. On 9 March 1994, JPC collected another four specimens at Keehuei, a small local village near Chengkung. This undescribed species belongs to the low-scale- row Callogobius group, but differs from other Callogobius species by having the following characters: different pattern of cutaneous papilose, different number cephalic sensory pores, fewer predorsal scales, first dorsal shape, and distinct color pattern on vertical fins. The key to all 8 low-scale-row Callogobius is also provided.

MATERIALS AND METHODS

All specimens were collected from the southeastern coast of Taiwan by scuba diving during our survey of marine fish fauna in Taiwan. Fresh specimens were first photographed and the color pattern described. The fish were then fixed in 10% formalin and transferred to 70% enthanol. All counts and measurements were made from preserved specimens. Both meristic counts and morphormetric measurements are listed in Table 1. Methods of measurements and counts follow Hubbs and Lagler (1958), except counts of the longitudinal and transverse scale rows which follow Hoese and Obika (1988). The longtitudinal scale rows are counted from the upper pectoral origin to the base of the caudal fin, and the transverse scale rows are counted from the anal fin origin upward and backward to the 2nd dorsal fin. The terminology of the cephalic sensory system followed Miller (1986) and Wongrat and Miller (1991) which are based on Sanzo (1911). Vertebrae were counted from radiographs. Abbreviations used for these characters include: D, dorsal fin; A, anal fin; P1, pectoral fin; P2, pelvic fin; LR, longitudinal scale rows; TR, transverse scale rows; Pred.S, predorsal scales; SL, standard length; HL, head length; BD, body depth; Pred L, predorsal length;

SD2L, length of snout to 2nd dorsal origin; SAL, length of snout to anal origin; CPD, caudal peduncle depth; ED, eye diameter; SnL, snout length; HW, head width; and Int, interorbital width. In the following descriptions, data in parentheses refer to the paratypes, if it is different from the holotype. The type specimens are deposited at the Museum of Institute of Zoology, Academia Sinica, Taipei, Taiwan (ASIZP), and Bernice P. Bishop Museum, Honolulu (BPBM).

Etymology.—This species is named for its blackish stripe at the outer margin of anal, and caudal fins. Distribution.—This new species has only been found at its type locality: Taitung County, southeastern Taiwan. Comparison.—C. nigromarginatus belongs to the low-scale-row Callogobius group (with 26 or fewer L.l.) as proposed by Goren et al. (1991). This species can be distinguished from other species of this group by the following characters (listed in Table 2): five predorsal and 7–8 transverse scales, pelvic frenum present, and with posterior oculoscapular pores. C. nigromarginatus and C. maculipinnis are the only two species of this group that have posterior oculoscapular pores (temporal sensory pore). C. nigromarginatus is mostly close to C. maculipinnis but can be distinguished by fewer predorsal scales (4–5 vs 6–7), fewer transverse scales rows (7–8 vs 10), and the longest JENG-PING AND SHAO: NEW SPECIES OF CALLOGOBIUS 463

Besides the posterior oculoscapular pores, C. nigromarginatus differs from C. amikami by fewer predorsal scales (5 vs 8), fewer anal rays (7 vs 8), the shape of the tongue (round vs truncate), and a horizontal stripe on body (absent vs. present). It differs from C. plumatus and C. dori because these two species have more predorsal scales (9–11) and truncate tongue. C. bauchotae and C. crassus have no pelvic frenum. C. nigromarginatus is also different from C. centrolepis by having fewer predorsal scales (5 vs 10–12) and fewer transverse scale rows (7–8 vs 10). As to other non low-scale-row Callogobius, C. sclateri and C. flavobrunneus have more than 26 lateral scales (29–32 in the former, 28–37 in the latter) and both have a stout body shape with ctenoid scales and reduced number of dorsal rays. C. nigromarginatus differs from them by having posterior oculoscapular and preopercular pores, and having fewer predorsal scales (5 vs more than 10 ).

ACKNOWLEDGMENTS

During the past five years (1989–1994), an intensive survey on inshore fish fauna in the waters around Taiwan was supported by a grant from the National Science Council of the Rebublic of China to the junior author (KTS). Also we thank M. Goren and S. C. Shen for reviewing and commenting on the manuscript.
