The natural history of mudskippers in northern Australia, with field identification characters
We provide field identification characters and report on the natural history of mudskippers (Gobiidae: Oxudercinae) in Cairns, Darwin, Derby and Broome, northern Australia.Nine species in four genera are recorded ( Boleophthalmus birdsongi, B. caeruleomaculatus, Periophthalmodonfreycineti, Periophthalmus argentilineatus, P. darwini, P minutus, P. novaeguineaensis, P. takila and Scartelaos histophorus).The intertidal zonation of mudskippers confor…
A new species of the gudgeon Bostrychus (Teleostei
A new species of the elcotrid genus Bostrychus is described from a single specimen obtained from a disturbed mangrove site at the Sementa River, in Selangor State, Malaysia.It resembles B. sinensis and B. strigogenys in vertebral number, body shape and interorbital pore pattern, but differs from all known species of Bostrychus by the ladder-like barred body markings, the spotted, dark-margined pectoral fins and low fin ray counts.It is the second…
A new species of carp gudgeon, 'Hypseleotris' (Pisces
A new species of eleotrid, Hypseleotris barrawayi, is described from the upper Katherine River, of the Daly River system of the Northern Territory.It differs from others in the genus by having distinct dark vertical bars on the body, the first and second dorsal fins are banded horizontally with light and dark pigment, the caudal fin usually has several dusky bars or rows of spots, has a dark baron the pectoral base, 26 vertebrae, preopercle with …
Additional records of frsh water fishes from Timor-Leste, with notes on the fish fauna of the unique land-locked Irasiquero River system
Timor is the largest of the Lesser Sunda Islands, which comprise the south-eastern part of the Indonesian Archipelago (Audley-Charles 1968).It is a non-volcanic island situated in the Outer Banda Arc which lies between the Sahul Shelf of Australia and the Sunda Shelf of South-east Asia (White et al. 2006).Timor-Leste (East Timor) occupies the eastern half of the island of Timor, encompassing an area of 14 875 km 2 (White et al. 2006).This note fo…
A New Species of the Circumtropical goby genus Gnatholepis Bleeker (Teleostei
A new species of Gnatholepis is described from northern Australia, where it is common on shallow intertidal rocky reefs.It is sexually dichromatic, with males having bright blue markings along the side of the body.The new species' closest relative is G. gymnocara Randall and Greenfield, 2001, which is restricted to the east coast of Queensland.Both these species are small, lack scales on the side of the head and lack enlarged canine teeth in the …
Two New Species of Periophthalmus (Teleostei
Two new species of mudskipper (genus Periophthalmus ) are described from mangrove habitats of north-western Australia.They both resemble small specimens of Periophthalmus novaeguineaensis Eggert, 1935, and have been confused with that species.Periophthalmus darwini n. sp. is distinguished by a combination of characters, in particular a greatly reduced first dorsal fin in both sexes.Periophthalmus murdyi n. sp. is distinguished by a combination of…
Description of a New Species of Cryptocentrus (Teleostei
A new species of Cryptocentrus is described from northern Australia.The species is distinctive in having an orbital tentacle, sensory papillae on ridged flaps on the head, transverse rows of preopercular mandibular sensory papillae, scales on the cheek, and 11 + 15 vertebrae.Species of Cryptocentrus normally have 10+16 vertebrae.The species occurs on silty sand substrates and is commonly trawled.Discussion on the species and species-groups in the…
New Records of Freshwater Fishes from East Timor
In October, 2003, the junior author had the opportunity to visit East Timor and collect freshwater fishes from several localities: from rivers near Aileu in the central mountains across to Lake Ira Lalaro near the eastern tip of the island.This collection is significant as very little is known of the freshwater fish fauna of the island of Timor.Full details of the aquatic habitats encountered and their ecology will be published separately.Few fre…
A New Genus for the Indo-Pacific Goby Species Gobius baliurus Valenciennes (Teleostei, Gobiidae, Gobiinae)
A new genus, Arcygobius, is created to include the gobiid fish species previously known as Gnatholepis baliurus (Valenciennes) and Gnatholepis calliurus Jordan and Seale.It is a gobiine, not a gobionelline (as is Gnatholepis), resembles the genus Acentrogobius and is distinguished from other Indo-Pacific gobiines by having the gill opening wide and reaching to below mid-eye, cheeks fully scaled, operclc scaled dorsally and with transverse sensory…
The Angalarri, Scortum neili Allen, Larson, and Midgley (Teleostei
Fourteen mature specimens of the Angalarri grunter (Scortum neili Allen, Larson and Midgley) were collected trom the main headwater tributary of the Angalarri River in the Victoria River system, Northern Territory, seventeen years after its original discovery at this site in 1981.The distinctive habitat features of this stretch of river include deep (5-6 m), wide (> 10 m) pools with closed dense canopy, submerged and exposed fringing tree roots, …
A new genus of small coral-reef goby (Teleostei
A new genus and species, Minysicya caudimaculata , is created for a small coral reef gobiine known so far from the Yaeyama Islands, Ryukyu Archipelago, Japan; Scott Reef off northern Western Australia; Lizard Island.Queensland; and the 1 uamotu Islands, French Polynesia.Phylogenetic analysis shows that Minysicya n. gen.forms a monophyletic group with live other genera including Bryaninops and Pleurosicya (commensal on various invertebrates and pl…
A New Genus of Small Gobiid Fish (Teleostei, Gobiidae) from the Indo-west Pacific, with Description of Two New Species
A new genus, Tryssogobius, is created for two new species of Indo-west Pacific gobiids (T.colini n. sp. and T. longipes n. sp.).The two species are distinguished by differences in fin rays counts, oculoscapular pores, body shape, and coloration.Both species are small, less than 30 mm SL, and occur in relatively deep coral reef habitats, where they hover above the substrate in a manner reminiscent of the microdesmid Nemateleotris
Lectotype designation for Gobius sarasinorum Boulenger (Pisces, Gobioidei, Gobiiade, Gobionellinae)
The gobionelline fishes of the genus Mugilogobius were recently revised by Larson (2001). The specimen intended to be the lectotype of Gobius sarasinorum Boulenger 1897, was illustrated (Larson 2001) and it was referred to as the lectotype in the text. However, in an oversight, the specimen was not formally designated as lectotype, nor were the remaining syntypes designated as paralectotypes. This short note is intended to rectify this, so that t…
A Review of the Mangrove Goby Genus Hemigoius (Gobioidei, Gobiidae, Gobionellinae)
The gobiid fish genus Hemigohius is reviewed and found to comprise two species, which are redescribed.The genus is considered to belong to the subfamily Gobionellinae, is closely related to the genera Mugilogohius and Pseudogohius, and can be distinguished from them by a combination of characters.Hemigohius is restricted to mangrove habitats in northern Australia and South-east Asia
A New Species of Egglestonichthys (Teleostei
A new species of the gobiid genus Egglestonichthys Miller and Wongrat is described from three specimens collected by trawl from the Arafura Sea and Van Diemen Gulf, northern Australia, and off Bombay, India.Egglestonichthys melanoptera (Rao), originally assigned to Callogobius, is re-described.The new species differs from E. melanoptera and E. patriciae in having very small eyes, a more narrow gill opening, and distinct brown bands and saddles on…
A Review of the Australian Endemic Gobiid Fish Genus Chlamydogobius, with Description of Five New Species
The Australian endemic gobiid genus Chlamydogobius is reviewed and five new species described as new.One of the new species is estuarine, found in coastal northern Australia; all the other species are restricted to freshwater springs and bores in inland Queensland, South Australia and the Nonhem Territory.Chlamydogobius belongs to the subfamily Gobionellinae and may be most closely related to Pseudogobius, Hemigobius and Mugilogobius.An artificia…
A new species of Scortum Whitley (Pisces
A new species of grunter (Teraponiidae) is described from fresh waters of the Northern Territory, Australia.Scortttm neili sp.nov. is described on the basis of 11 specimens collected from a tributary of the Angalarri River, and from the East Baines River, in the Victoria River sy.stem of the Timor Sea drainage.It is distinguished from the other three species of Scortttm by a combination of features including counts of transverse cheek scale rows,…

The tropical Indo-Pacific coral reef goby genera Luposicya Smith and Pleurosicya Weber are reviewed. Luposicya is represented by a single species, L. lupus, which is redescribed here. Pleurosicya is represented by 16 species of which eight (P. annandalei Horne ll and Fowler, P. bilobata (Koumans), P. boldinghi Weber, P. labiata (Weber), P. micheli Fourmanoir, P. mossambica Smith, P. muscantm (Jordan and Seale) and P. prognatha Goren) were previou…
A new species of Bryaninops (Pisces
A new species of commensal goby, Bryaninops nexus, is described from northern Australia and the Ryukyu Islands.This fish hovers, often upside down, among the branches of large staghorn corals ( Acropora ).It is unique in that the nostrils are absent, replaced by a low oval rim.Additional material of four species of Bryaninops Smith is reported on; three are new records for Japan
Phyllogobius, a new generic name for Cottogobius platycephalops Smith (Pisces
A new genus, Phyllogobius gen.nov., is proposed for Cottogobiusplatycephalops Smith, a species of commensal goby which does not belong in Pleurosicya Weber, the senior synonym of Cottogobius Koumans.The genus is characterised by an unrestricted gill opening forming a broad free fold across the isthmus, at least half the first gill arch bound by membrane to the opercular wall, and the premaxilla with ascending and articular processes broadly fused…
A revision of the gobiid genus Bryaninops (Pisces), with a description of six new species
The tropical Indo-Pacific gobiid genus Bryaninops Smith is reviewed and the genus Tenacigobius Larson and Hoese included as a synonym.These small fishes are commensal chiefly on gorgonians and antipatharians.The three previously-known species, Bryaninops eryihrops (Jordan and Seale), B. ridens Smith and B. yongei (Cohen and Davis), are redescribed and figured.Six new species are described: B. amplus, B. dianneae, B
