0D1D5E2A8844FFC971A1FB2EB408FC58.taxon	diagnosis	Diagnosis. Body elongate, round anteriorly, compressed posteriorly, deepest in middle and tapering at both ends, tail slender and attenuate, its tip delicate and frequently broken. Dorsal fin begins over gill opening or slightly behind, anal fin begins immediately behind anus, the fins confluent with caudal fin. Pectoral fin absent. Head and snout slender, elongate, and slightly depressed, snout projecting beyond tip of lower jaw. Anterior nostril tubular, near tip of snout; posterior nostril located on dorsal surface of head or body, from a point just posterior to eye to dorsal surface of body well behind dorsal origin (Fig. 1). Lateral line on body complete; 5 SO pores, 8 – 10 + 2 – 4 IO pores, 11 – 16 POM pores. Teeth small, conical, in narrow bands on jaws and vomer; vomerine tooth patch elongate, sometimes with a median series of enlarged teeth anteriorly. Species. Nettenchelys contains nine known adult species: N. dionisi Brito 1989; N. erroriensis Karmovskaya 1994; N. exoria Böhlke & Smith in Smith et al. 1981; N. gephyra Castle & Smith in Smith et al. 1981; N. inion Smith & Böhlke in Smith et al. 1981; N. paxtoni Karmovskaya 1999; N. proxima n. sp.; N. pygmaea Smith & Böhlke in Smith et al. 1981; and N. taylori Alcock 1898. They are distinguished by the position of the posterior nostril (Figure 1), the presence or absence of the median supratemporal pore, infraorbital pore counts, and the form of the vomerine teeth (Table 1). A tenth species, Nettenchelys belottii (D’Ancona 1928), is known only from a larva.	en	Smith, David G., Lin, James, Chen, Hong-Ming, Pogonoski, John J.

0D1D5E2A8841FFCF71A1FF13B001FD02.taxon	discussion	Remarks. This species was described from two small specimens, 14.5 and 24 mm TL. The larger one, the lectotype, is clearly a larval Nettenchelys. The smaller one, the paralectotype, is doubtful; it lacks the characteristic midlateral spot, and the posterior pigmented swelling in the gut seems closer to the anus than it is in larval Nettenchelys (Fig. 2, bottom). We suspect that it may be a small specimen of Saurenchelys. D’Ancona did not give the total myomere counts, only the preanal counts (51 for the lectotype), and there are no other characters that could link the larva to an adult. Considering the restricted distributions of the known species of Nettenchelys and the prevalence of endemism in the Red Sea, it is unlikely that this is the larva of one of the nine described species. It most likely represents a distinct species that has not yet been collected as an adult. The name is available and could be applied to the species if the adult is ever found.	en	Smith, David G., Lin, James, Chen, Hong-Ming, Pogonoski, John J.

0D1D5E2A8841FFCE71A1FAAAB209FF36.taxon	discussion	Remarks. Smith & Castle (1982: 18) described a larva, Nettenchelys sp. B, based on two specimens collected in the eastern North Atlantic, one near the Azores and one near the Canary Islands (Smith & Castle 1982: fig. 12). These larvae may belong to Nettenchelys dionisi, a species that was unknown in 1982. Both the holotype and paratype of N. dionisi appear to be incomplete; the vertebral counts of 165 and 132 respectively seem far too low for a nettastomatid. The preanal lengths of the two specimens given by Brito (1989: table 1) are 30.8 and 37.2 % TL for the holotype and paratype respectively. If the specimens are incomplete, and if the paratype has lost more vertebrae than the holotype, then it would be expected that any proportional measurement given as a percentage of TL would be greater in the paratype. This is indeed what we see, providing further evidence that both specimens have lost part of the tail. The two specimens of Nettenchelys sp. B larvae have 235 – 236 total myomeres (Smith & Castle 1982: 18); if these represent the larvae of N. dionisi, then the adults would have a comparable number of vertebrae.	en	Smith, David G., Lin, James, Chen, Hong-Ming, Pogonoski, John J.

0D1D5E2A8840FFC371A1FA0BB1F8FAEA.taxon	discussion	Remarks. Considerable variation occurs in this species over its range. This is particularly evident in the preanal lateral-line pores, maxillary pores, preanal vertebrae, precaudal vertebrae, and preanal dorsal rays (Table 2). The posterior nostril appears slightly closer to the eye in the Australian specimens than in the Taiwan specimens, although not nearly as close as in N. proxima. We hesitate to describe these variants as species based on such a small sample size and without any genetic information. We simply note the differences and leave the nomenclatural decisions to future studies when more information is available. The typical IO pore count for this species is 9 + 3. One specimen from Australia had eight pores along the upper jaw, and another Australian specimen had an extra pore behind the eye on one side. We also note an inconsistency in the number of POM pores reported by Smith et al. (1981: 553 and fig. 11). The text states 17 POM pores, but the figure shows 13 (11 + 2). We suspect that the latter figure is correct. Smith et al. (1981) did not give vertebral counts for the holotype, but a radiograph of this specimen is available online (http: / / science. mnhn. fr / institution / mnhn / collection / ic / item / search / form). This image is divided into two parts, anterior and posterior. Assuming that there is no overlap or duplication in these two parts, we obtained the following counts: PDV ca. 8, PAV ca. 47, PCV ca. 92, TV 160 +.	en	Smith, David G., Lin, James, Chen, Hong-Ming, Pogonoski, John J.

0D1D5E2A884CFFC771A1FE33B7D1FB2F.taxon	diagnosis	Diagnosis. Nettenchelys proxima differs from all other species in the genus except N. gephyra and N. pygmaea in having an enlarged median series of teeth at the anterior end of the vomer. It differs from N. gephyra in having the posterior nostril immediately behind the eye (approximately midway between eye and supratemporal canal in N. gephyra), in having 78 PCV (79 – 101 in N. gephyra, but 91 – 101 in specimens from Taiwan), and in having 9 + 2 IO pores (8 – 9 + 3 – 4 in N. gephyra). It differs from N. pygmaea in its larger size (251 mm in the holotype, an immature female, vs. 201 mm for the largest known N. pygmaea and 151 mm for a mature female) and slight differences in some meristic and morphometric characters (Table 1).	en	Smith, David G., Lin, James, Chen, Hong-Ming, Pogonoski, John J.

0D1D5E2A884CFFC771A1FE33B7D1FB2F.taxon	etymology	Etymology. From the Latin proxima, near, referring to the position of the posterior nostril, close to the eye; also referring to its close resemblance to N. gephyra and N. pygmaea. An adjective.	en	Smith, David G., Lin, James, Chen, Hong-Ming, Pogonoski, John J.

0D1D5E2A884CFFC771A1FE33B7D1FB2F.taxon	discussion	Remarks. This new species resembles only Nettenchelys gephyra and N. pygmaea in having an enlarged series of median teeth at the anterior end of the vomer. It differs from the latter two species primarily in the characters mentioned in the diagnosis: nostril position, precaudal vertebrae, and size. It further differs from N. gephyra in PADR (96 vs. 102 – 112 in specimens from Taiwan), upper jaw length (56.3 vs. 49.0 – 55.5 % head in specimens from Taiwan), and lower jaw length (52.5 vs. 45.1 – 51.7 % head). It differs from N. pygmaea in PDV (6 vs. 7 – 8), PAV (44 vs. 40 – 43), PCV (78 vs. 75), postorbital pores (2 vs. 3), predorsal length (31 vs. 33 – 35 % preanal), and head length (27.6 vs. 30 – 33 % preanal). Because of the small sample size, however, it is uncertain how meaningful these minor differences are. The second specimen listed, USNM 134972, was included in Nettenchelys gephyra by Smith et al. 1981, although they did not make it a paratype because of its small size and poor condition. We tentatively reassign it here to N. proxima because the posterior nostril seems to be closer to the eye than it is in N. gephyra, but its size and condition make its positive identification uncertain. Hence we exclude it from the type series.	en	Smith, David G., Lin, James, Chen, Hong-Ming, Pogonoski, John J.

Adults are known from two widely separate locations in the western Atlantic: the northern Gulf of Mexico and the southern Caribbean Sea. Larvae are known from a much wider area, including the western Gulf of Mexico, the Bahamas and the Gulf Stream off the east coast of the United States, the Antilles, and the Sargasso Sea. The number of myomeres in these larvae shows a slight difference between specimens from the Gulf of Mexico (ca. 220 – 236, seven specimens) and elsewhere (ca. 227 – 251, 22 specimens) (Smith & Castle 1982: 16).	en	Smith, David G., Lin, James, Chen, Hong-Ming, Pogonoski, John J.
