Abstract:
A new species of nine-spined stickleback, Pungitius modestus, is described based on the holotype and 17 paratypes (38.7–51.7 mm standard length) collected from the inland area of Yamagata Prefecture, northern Honshu, Japan. The new species is distinguished from the other species of Pungitius by the following combination of characters: 30–32 small unconnected lateral plates; dorsal-fin rays VIII–X (usually IX)+9–11; anal-fin rays 7–10 (usually 8); pectoral-fin rays 10; a short spiny dorsal fin base (26.5%–29.8% SL); the first spiny dorsal fin spine behind the pectoral-fin base; a long pre-anal

Abstract:
Two new species of stargazers in the Uranoscopus albesca species-complex of the family Uranoscopidae are described from Papua New Guinea, which shares among other characters a concave posterodorsal margin of the pectoral fin. Uranoscopus brunneus n. sp. is described from a single specimen from off southwestern New Britain, and is characterised by lower edge of preopercle with 8 spines; labial fimbriae poorly-developed; anterior nostril with a long tubiform valve, posterior nostril a slit-like pore; supracleithrum with a sharp spine at rear end and five small spines inside; dorsoposterior margi

Abstract:
The Siluriformes, popularly known as catfishes, are probably the vertebrate group with the highest diversity of venomous animals, even though only approximately a hundred venomous catfishes are reported to date. Venomous catfishes might present a delivery system apparatus, formed by an unbranched ray at the leading edge of pectoral and dorsal fins (spine), which can be stiffened and pungent, while venom glands can be present at the surface of such spines and/or the axillary region. This work investigated the presence, morphology and distribution of glands and pectoral-fin delivery apparatus in

Abstract:
Neomerinthe ornithoptera n. sp., described on the basis of three specimens from Fiji and the Wallis and Futuna Islands, southwestern Pacific Ocean, was previously reported as Neomerinthe pallidimacula (Fowler 1938), due to its characteristic lack of both lateral lacrimal and second preopercular spines. The new species is clearly distinguished from Indo-Pacific congeners, including N. pallidimacula, by the following combination of characters: pectoral-fin rays 18; scale rows in longitudinal series 44 or 45; pored lateral-line scales 23; scale rows above lateral line 6 or 7, below lateral line 1

Abstract:
Since it was described, Cathorops multiradiatus has been differentiated from congeners through the large number of anal-fin rays ( 25 - 27). In this study, C. multiradiatus is redescribed and a new sympatric species with similar number of anal-fin rays is described and intersexual differences of both species evaluated. Cathorops manglarensis differs from C. multiradiatus by possessing few gill rakers on the first arch ( 13 - 16 vs. 16 - 19), a longer maxillary barbel (28.4 - 38.2 vs. 22.9 - 27.7% SL), longer pectoral-fin spine (18.5 - 22.5 vs. 16.9 - 18.7% SL), posterior margin of pectoral-fin

Abstract:
The acanthodian Paucicanthus vanelsti gen. et sp. nov. is described from six body fossils from Lower Devonian (Lochkovian) rocks of the southern Mackenzie Mountains, Northwest Territories, Canada. This new species is unique among acanthodians in that it lacks both pectoral and pelvic fin-spines. In the absence of fin-spines, the leading edges of the pectoral and pelvic fins are reinforced by enlarged scales. The anatomy of the acanthodiform Traquairichthys pygmaeus is similar to P. vanelsti in that both lack pelvic fin-spines, although T. pygmaeus also lacks pelvic fins. Similarly, the acantho

Abstract:
A new species of deepwater gurnard, Pterygotrigla (Otohime) madagascarensis sp. nov. is described, based on two specimens collected on the upper continental slope south of Madagascar, in the southwestern Indian Ocean. The new species belongs to the tropical Indo-Pacific subgenus Otohime in having a short rostral projection, short posttemporal spine, long opercular spine and no cleithral spine. It is most similar to P. (O.) multipunctata, and P. (O.) urashimai, in having no large blotch on the first dorsal fin, a jet-black blotch and no white ocellus on the inner pectoral-fin surface, with no s

The presence of the sisorid catfish genus Erethistoides in Myanmar, represented by three new species, is recorded for thefirst time. This discovery from the Irrawaddy and Sittang river drainages from central Myanmar and the Ann ChaungRiver drainage in western Myanmar extends the documented range of the genus beyond the Ganges/Brahmaputra Riverbasin. Erethistoides longispinis is distinguished from congeners in having the following unique combination ofcharacters: length of the dorsal-fin spine 24–27% SL, length of the pectoral-fin spine 29–35% SL, and absence ofproximally-directed serrations on

Abstract:
Sound production capabilities and characteristics in Loricariidae, the largest catfish family, have not been well examined. Sounds produced by three loricariid catfish species, Otocinclus affinis, Pterygoplichthys gibbiceps, and Pterygoplichthys pardalis, were recorded. Each of these species produces pulses via pectoral-fin spine stridulation by rubbing the ridged condyle of the dorsal process of the pectoral-fin spine base against a matching groove-like socket in the pectoral girdle. Light and scanning electron microscopy were used to examine the dorsal process of the pectoral-fin spines of t
