Merodoras nheco, new genus and species of Doradidae (Siluriformes) is described from Rio Paraguay basin, Brazil. The new genus belongs to the new subfamily Astrodoradinae, a monophyletic group formally named herein that includes, besides Merodoras, Amblydoras, Anadoras, Astrodoras, Hypodoras, Physopyxis, and Scorpiodoras. This group is diagnosed by the possession of: lacrimal serrated and participating in the orbital margin, four to seven pleural ribs; spines on the postcleithral process; postero-inferior portion of the coracoid exposed. Merodoras nheco, new species, is distinguished from other doradids by the unique combination of the following characteristics: 1) tips of retrorse spines on the midlateral scutes ventrally oriented in adults; 2) incomplete lateral line, with only a few midlateral scutes anteriorly; 3) pectoral girdle entirely exposed ventrally, with the opening of the arrector ventralis inferior reduced to a small fossae on the anterior edge of the coracoid; 4) caudal fin truncate; 5) dorsal-fin spine smooth, without serrae on both faces; 5) lacrimal serrated; 6) lateral ethmoid serrated. Merodoras nheco inhabits the “Pantanal Matogrossense,” a flooded portion of the upper Rio Paraguay basin in western Brazil.

A new genus and species of the percoid family Symphysanodontidae, Cymatognathus aureolateralis are described based on three specimens collected from North Sulawesi, Indonesia. The new species shares with the confamilial genus Sym-physanodon the unique supraneural and spinous dorsal-fin pterygiophore insertion pattern usually of 0/0/0+2+1/1/, T-shaped first supraneural, foreshortened base of the penultimate ventral procurrent caudal-fin ray, well-developed outer tooth patches at anterior tips of both jaws as well as along the medial surface of most of the length of the coronoid process of the dentary. The new species, however, is distinguishable from members of Symphysanodon by the following diagnostic characters: posterior tip of coronoid process of dentary abruptly depressed, so that teeth on anterior portion appear as an elevated patch, anterior tip of upper jaw not notched, and posterior nostril horizontally slit-like. Although the new species superficially resembles the members of the genus Giganthias (Giganthiidae) and some members of the subfamily Anthiadinae (Serranidae) in the unique characters it shares with Symphysanodon, it differs from Giganthias in having the above-mentioned unique pterygiophore insertion pattern and tips of all dorsal- and pelvic-fin spines smooth (vs. pterygiophore insertion pattern 0/0/2/1+1/1/, and tips of second, third and/or fourth dorsal- and pelvic-fin spines serrated), and from the members of Anthiadinae in having two flat opercular spines (vs. three) and 10 + 15 = 25 vertebrae (vs. 10 + 16–18 = 26–28). A revised diagnosis of the Symphysanodontidae is presented.

A partial skeleton of a hybodontiform shark-like chondrichthyan from the Upper Jurassic Kimmeridge Clay Formation of Dorset, England, is described and designated as a new genus and species, Durnonovariaodus maiseyi gen. et sp. nov. The holotype and only known specimen, which is represented by disarticulated splanchnocranial elements with associated teeth, a single dorsal fin spine, the pelvic girdle, as well as unidentifiable cartilage fragments, plus countless dermal denticles, exhibits a puzzling combination of dental and skeletal features, providing important new insights into the morphological and ecological diversity of hybodontiforms. Durnonovariaodus gen. nov. displays a unique set of dental characters, showing close morphological resemblance to Secarodus from the Middle Jurassic of England, which was erected for distinctive, strongly labio-lingually compressed multicuspid cutting teeth originally described as Hybodus polyprion. Skeletally, Durnonovariaodus gen. nov. resembles Hybodus and Egertonodus in having a palatoquadrate with a palatobasal process and an ethmoidal articular surface, combined with the possession of dorsal fin spines ornamented with costae. Therefore, and given the absence of any conclusive phylogenetic framework, Durnonovariaodus maiseyi gen. et sp. nov. is here tentatively referred to Hybodontidae until more complete material becomes available in order to enable a more reliable suprageneric identification. The holotype of Durnonovariaodus maiseyi gen. et sp. nov. contains two separate pelvic half-girdles, a feature previously considered as evolutionarily primitive among hybodontiforms. However, unfused pelvic half-girdles also occur in the supposedly closely related species Hybodus hauffianus and may in fact have been more widely distributed among hybodontiforms than previously thought, thus rendering the phylogenetic utility of separated pelvic half-girdles for inferring hybodontiform interrelationships difficult and unresolved.

A New Species

A new fangblenny, Adelotremus deloachi, is described on the basis of three specimens, 29‒35 mm SL, from Bali and Lembeh Strait, Indonesia. All these specimens were collected in 10‒17 m depth on sandy slopes. The new species differs from Adelotremus leptus, its Red Sea and only congener, in having a pair of mid-dorsal supratemporal pores (vs. a single pore), dorsal-fin spines X (vs. IX) and precaudal and caudal vertebra 12 + 23 (vs. 13 + 19). The discovery of a second species requires slight modification of the diagnosis of the genus. Unlike the five other nemophine genera, Adelotremus differs most notably in having the third infraorbital bone and associated sensory pores absent, and the combination of ventral margin of gill opening opposite the dorsalmost 5th or 6th pectoral-fin ray, total dorsal-fin elements 28‒29 and interorbital pores 2. With a total of four specimens of Adelotremus, it is now apparent that several features of the cephalic pore arrangement of the genus are different from that found in Petroscirtes, its presumed sister genus. Recent color photographs indicate that both species of Adelotremus exhibit marked sexual dichromatism with males having a conspicuous ocellus anteriorly in the dorsal fin that is absent in females.

A new genus and species of goby, Gymnesigobius medits sp. nov., is described from the western Mediterranean slope bottoms at the Balearic Islands. The new goby belongs to the Gobius-lineage (Gobiinae). Examination of the single known specimen exhibits a unique combination of morphological characters which could not be fitted to any known genus. Gymnesigobius gen. nov. is morphologically distinguished from all other genera in the Gobius-lineage by the following combination of characters: chin without fold or barbels; mouth terminal with anterior tip above horizontal level of lower eye edge; predorsal area and first dorsal fin base naked; pelvic fin anterior membrane well developed; head with anterior oculoscapular and preopercular canals, posterior oculoscapular canal absent; pores of head canals enlarged, e.g. pores α and ρ larger or of about the same size as interspaces to pore β; six transverse suborbital rows of sensory papillae, four continuous suborbital rows in front of row b, fifth row divided in three parts but in front of row b, sixth row just as superior part above row b and below pore α; longitudinal suborbital row b barely reaching forward to the vertical from posterior edge of eye. A full description of the new genus and species is provided. The new species, collected at a depth of between 344 and 364 m (mean depth of 354 m), is one of very few gobiid species found at bathyal depths.

Infor Mation

Material of three similar and probably related genera of the viviparous ophidiiform family, Bythitidae, has been studied.The monotypic Hastatobythites is only known from the original two specimens; re-examination of the paratype and infor-mation of the holotype clearly demonstrates the validity of the genus. The revision of Saccogaster (Cohen & Nielsen1972) was based on 15 specimens. Since then 29 additional specimens have been collected representing 11 species, threeof which are here described: S. brayae, horrida and nikoliviae. Three of the 11 Saccogaster species, S. melanomycter, S.normae and S. rhamphidognatha, differ so much from the remaining eight that a new genus, Parasaccogaster, is de-scribed. The main diagnostic characters used for the three genera are: A pair of spines on frontal plate behind eyes, spineson snout, length of gill filaments on anterior arch, number and length of developed gill rakers, size of gill opening, thick-ness of skin, head pores, otolith morphology, color marks on head, neuromasts on head and head morphometrics, fin ray counts.
