Two genera of barracudinas with luminescent duct in abdominal cavity, Lestrolepis and Lestidium, collected from around Taiwan are studied. Two species in each genus are recognized in Taiwan, including one new species in each genus. New diagnostic characters are used to distinguish these species. Lestrolepis nigroventralis sp. nov. is similar to Lestrolepis intermedia and can be distinguished by having 32–35 prehaemal vertebrae; dorsal-fin origin slightly in front of midline of distance between origins of pelvic and anal fins, distance between origins of dorsal and pelvic fin 9.8–11.7% SL; and pelvic-fin origin at or slightly behind midline of body, prepelvic length 50.6–52.6% SL. Lestidium orientale sp. nov. is similar to Lestidium atlanticum and can be distinguished by having prehaemal vertebrae 37–40; caudal vertebrae 41–44; a relatively short and deep head, reflected by a shorter snout (9.7–10.4% SL), shorter upper jaw (8.6–10.1% SL), shorter lower jaw (11.9–13.7% SL) and a deeper head (31.2–33.9% HL). Data of Lestrolepis japonicus and Lestidium prolixium collected from Taiwan, as well as two Atlantic congeners, are provided. DNA barcoding is conducted to support the recognition of these new species.

The new anchovy Stolephorus babarani n. sp. is described on the basis of 26 specimens collected from Panay Island, central Philippines. The new species closely resembles Stolephorus bataviensis Hardenberg 1933 and Stolephorus baweanensis Hardenberg 1933, all these species having a long upper jaw (posterior tip extending beyond posterior margin of preopercle), and numerous dusky spots on the suborbital area (in adults), snout and lower jaw tip. However, the new species differs from S. bataviensis by usually having the posterior tip of the depressed pelvic fin not reaching to vertical through the dorsal-fin origin (vs. extending beyond vertical through dorsal-fin origin), a shorter head (23.9–25.5% of standard length vs. 25.3–28.0%), and a greater distance between the dorsal-fin origin and pectoral-fin insertion (D–P1; 133.9–151.8% of head length vs. 109.9–136.3%). Stolephorus babarani is distinguished from S. baweanensis by having a shorter snout (3.6–3.9% of standard length vs. 3.8–4.6%). Moreover, the new species can be distinguished from S. bataviensis and S. baweanensis by higher gill raker counts on the first and second gill arches (16–18 + 21–23 and 10–13 + 18–21, respectively, vs. 14–17 + 19–22 and 9–12 + 17–20 in S. bataviensis and 14–17 + 19–22 and 9–12 + 17–21 in S. baweanensis). Stolephorus babarani is separated by 5.3% and 10.7% mean p-distances in the mitochondrial COI from S. baweanensis and S. bataviensis, respectively.

This study reports five species of Pareuchiloglanis in the Lancangjiang drainage of China, including descriptions of two new species: P. abbreviatus sp. nov., P. gracilicaudata, P. kamengensis, P. myzostoma and P. prolixdorsalis sp. nov. The two new species are distinguished from P. feae, P. poilanei, P. sichuanensis and P. tianquanensis by a shorter adipose-fin base and the adipose-fin base being separated from the caudal fin, differ from P. sinensis, P. macrotrema, P. longicauda and P. rhabdurus by a more restricted gill opening (not reaching the base of the first pectoral-fin element ventrally), and differ from P. songmaensis by an anal-fin ray count of ii-3-4 (vs. ii-8). Pareuchiloglanis abbreviatus is distinguished from congeners by the tip of the dorsal fin reaching the origin of the adipose fin when depressed. Pareuchiloglanis prolixdorsalis is distinguished from P. gongshanensis, P. macropterus and P. kamengensis by lacking a sulcus between the lower lip and the base of the maxillary barbel, and differs from P. anteanalis by the shorter pectoral fin, the pectoral fin not reaching to the origin of pelvic fin. It differs from P. gracilicaudata, P. myzostoma, P. nebulifer and P. robusta by a caudal-fin ray count of 6+7 (vs. 7+8), and differs from P. abbreviatus by the tip of dorsal fin not reaching to the origin of the adipose fin when depressed (vs. reaching). It differs from P. songdaensis by the distance between the origin of the pelvic fin to the base of the anal fin being longer than that to the mouth (vs. equal).

Two new species of the scorpionfish genus Trachyscorpia are described on the basis of 20 and 7 specimens collected from Australasia at depths of 731–1020 m and the southwestern Indian Ocean at depths of 620–1080 m respectively. The two new species, classified into the subgenus Mesoscorpia, are distinguished from the only other member of the subgenus, T. (M.) eschmeyeri, by the following characters: the tympanic spines absent (vs. usually present in the latter), the upper-jaw lip well developed, covering the premaxillary tooth band laterally (vs. lip poorly developed, the premaxillary teeth exposed laterally), scales absent on the lateral surface of the maxilla (vs. scales present), and 4 blackish saddles on the body in preserved specimens (vs. no blackish saddles). Trachyscorpia (M.) carnomagula sp. nov. differs from T. (M.) longipedicula sp. nov. in having 57–63 scale rows in longitudinal series (vs. 50–53 in the latter). They are also distinguished by several morphometric characters, including lengths of pelvic-fin spine and soft ray, and first anal-fin spine. The subgenus Mesoscorpia is redefined. A key to the species of Trachyscorpia and comments on distribution of T. (M.) eschmeyeri are also provided.

Twelve species of the genus are recognized: Epigonus angustifrons Abramov & Manilo, 1987; E. denticulatus Dieuzeide, 1950; E. elongatus Parin & Abramov, 1986; E. exodon Okamoto & Motomura, 2012; E. lenimen (Whitley, 1935); E. macrops (Brauer, 1906); E. marimonticolus Parin & Abramov, 1986; E. marisrubri Krupp, Zajonz & Khalaf, 2009; E. pectinifer Mayer, 1974; E. robustus (Barnard, 1927); E. telescopus (Risso, 1810); E. waltersensis Parin & Abramov, 1986, and two new species, E. bispinosus n. sp. and E. idai n. sp. Epigonus bispinosus and E. idai belong to the E. constanciae group, defined as having a pungent opercular spine, more than 45 pored lateral-line scales, and lacking an isolated dorsal fin spine between the first- and second dorsal fins. Epigonus bispinosus differs from other members of the group in having two small spines on the symphysis of lower jaw, a pair of ribs on the last abdominal vertebra, 10 + 15 vertebrae, 31–33 gill rakers and lacking a maxillary mustache-like process. Epigonus idai differs from other members of the group in having a pair of ribs on the last abdominal vertebra, 4–5 tiny projections present on symphysis of lower jaw, 10 + 15 vertebrae, strongly ctenoid scales, and 28–29 gill rakers, and in lacking a maxillary mustache-like process. A key to the species, photographs, diagnoses, and distributions in the Western Indian Ocean are given.

Three New Species

Three new species of pinguipedid fishes from northern Australia are described based on specimens collected by deep water demersal trawling. Parapercis algrahami sp. nov. is recorded from off Dunk Island, Qld, south to Newcastle, NSW, in 67–333 m. It is distinct in having five narrow transverse dark bars across the upper body and a dark spot dorsally on the caudal-fin base, 6 canine teeth in outer row at front of lower jaw, palatines with 1–2 rows of teeth, and predorsal scales extending far forward on the nape to the posterior portion of the interorbital region. Parapercis imamurai sp. nov. is recorded from off Saumarez Reef, Qld, south to off Coffs Harbour, NSW, in 256–405 m. It is unique in having colouration that includes a broad dusky bar from lower margin of eye across the suborbital region and three broad dusky bands crossing the body between the middle of the soft dorsal-fin and the caudal-fin base, 10 canine teeth in outer row at front of lower jaw, and the fifth dorsal-fin spine longest. Parapercis pogonoskii sp. nov. is unique in having a combination of three reddish-brown vertical bars on the upper body between the anterior and posterior portions of the soft dorsal fin, the soft dorsal fin with two large dusky blotches and caudal-fin base with a dusky blotch in the upper corner, 8–10 canine teeth in outer row at front of lower jaw, fifth dorsal-fin spine longest, angle of subopercle with a single broad spine, and angle of preopercle with 4–5 large widely-separated spines. Comparison of the mitochondrial cytochrome c oxidase subunit 1 (CO 1) genetic marker utilised in DNA barcoding produced significant genetic divergences of at least 8.1% and 14.1% between P. algrahami sp. nov. and P. pogonoskii sp. nov. respectively and their closest sampled congeners.        The geographic range of Parapercis rubromaculata Ho, Chang & Shao, 2012 is extended from Taiwan to the southern hemisphere waters off Western Australia, based on specimens collected from Shark Bay, north to Ashmore Terrace, in depths of 56–107 m. A revised diagnosis for the species is presented, meristic, morphometric and DNA barcoding data for the two populations are compared, and a detailed description of the colouration of fresh and preserved specimens from Australia is provided. Previous records of Parapercis macrophthalma (Pietschmann, 1911) from Western Australia are established as misidentifications of Parapercis muronis (Tanaka, 1918) and the latter is thereby confirmed from the southern hemisphere and Australian waters for the first time. Comparative meristic, morphometric and DNA barcoding data is provided for populations of P. muronis from Japan, Philippines and Western Australia.

Two new species of Imparfinis are described from the trans-Andean region of Colombia. Imparfinis timana is diagnosed by having longer anal fin base (12.4-15.5% in SL), in combination with long adipose fin (24.6-31.3% in SL), 5-6 gill rakers on the first ceratobranchial, 42-43 vertebrae and additional measurements. Imparfinis usmai is distinguished by the combination of first ray of dorsal fin longest, but not projected as a long filament, long adipose fin (21.1-27.0% in SL), maxillary barbel exceeding pelvic-fin base, 39-40 vertebrae, upper caudal-fin lobe pointed and longer than lower lobe, lower lobe rounded, 7-8 gill rakers on the first ceratobranchial, as well as additional measurements. Imparfinis timana is only known from río Guarapas, a small tributary of the upper course of the río Magdalena. Imparfinis usmai is broadly distributed in the upper basin of ríos Cauca and Magdalena, and in the lower Patía river basin. The restricted distribution of I. nemacheir to trans-Andean drainages (Atrato, Magdalena, and Lago de Maracaibo) is also discussed.
