Gerald R. Allen and Rudie H. Kuiter: Descriptions of two New Wrasses of the Genus Cirrhilabrus (Labridae) from Indonesia, pp. 133-140
Two new species of labrid fishes are described from Indonesian seas. Cirrhilabrus aurantidorsalis, new species, is described from a single male specimen, 84.1 mm SL, collected off Togean Islands in Tomini Bay, Indonesia. It is closely allied to C. solorensis, but differs on the basis of male colour pattern, particularly the bright orange area on the upper back and dark violet “crown” on the forehead. Cirrhilabru tonozukai, new species, is described from three specimens, 55.8-58.1 mm SL, collected at the Baggai Islands off central eastern Sulawesi, Indonesia. It is closely related to C. filamentosus, but males have a shorter dorsal fin filament and differ in colour pattern, as well as attaining a smaller size. These two species differ from other members of the genus (hence their placement in the subgenus Cirrhilabrichthys Klausewitz) by a combination of characters that include a prolonged, filamentous extension of the posterior dorsal spines in males, a rounded caudal fin, and a single row of cheek scales.
Gerald R. Allen and Aaron P. Jenkins: A Review of the Australian Freshwater Gudgeons, Genus Mogurnda (Eleotridae) with Descriptions of Three New Species, pp. 141-156
The six Australian members of the freshwater fish genus Mogurnda are reviewed, including description of three new taxa. Mogurnda adspersa (Castelnau) ranges southward in Pacific coast drainages from Cape York Peninsula to the Clarence River of northern New South Wales. It so also widespread in the Murray-Darling system of inland New South Wales and Queensland. Mogurnda mogurnda (Richardson) is distributed across northern Australia from the Kimberley region to Cape York Peninsula. Mogurnda larapintae (Zietz) is confined to the Finke River system of central Australia. It was formerly confused with M. mogurnda, but is clearly separable on the basis of its smaller scales. Mogurnda oligolepis new species is described from 75 specimens, 15.8-62.7 mm SL, collected in the Kimberley region of northern Western Australia. It is similar to M. mogurnda, but differs in having larger body scales, modally fewer dorsal and anal fin rays, and a smaller maximum size. Mogurnda clivicola new species is described from 61 specimens, 21.3-69.8 mm SL collected in the northern flinders Ranges of South Australia. It is distinguished from other central desert Mogurnda (i.e. M. larapintae and M. thermophila) by its colour pattern and modal counts for vertebrae, lateral scales, predorsal scales, circumpeduncular scaler, and pectoral rays. Mogurnda thermophila, new species is described from 25 specimens, 12.6-98.6 mm SL, collected from the complex of thermal springs at Dalhousie, South Australia. It is similar in general appearance to M. larapitae, but has larger scales.
Gerald R. Allen and Bradley J. Pusey: Hephaestus tulliensis De Vis, a valid Species of Grunter (Terapontidae) from Fresh Waters of North-eastern Queensland, Australia, pp. 157-162
Hephestus tulliensis De vis was formerly considered a junior synonym of H. fuliginosus Macleay, but evidence is provided for its recognition as a valid species. The two species differ in a variety of characters including number of lateral body scales, preopercular and opercular serration/spination, body depth, eye width, interorbital with, maxillary length, caudal peduncle depth, and length of fin spines/soft rays of the dorsal, anal, pectoral, ad pelvic fins, a redesription is provided for H. tulliensis and it is compared with H. fuligiosus, the two species having sympatric distributions in certain freshwater habitats of north-eastern Queensland, Australia.
Gerald R. Allen and Samuel J. Renyaan: Pseudomugil ivantsoffi (Pseudomugilidae), a new species of blue-eye from the Timika region, Irian Jaya, pp. 163-168
Pseudomugil ivantsoffi, a new species of blue-eye, is described on the basis of 60 specimens, 17.9-30.8 mm SL, collected from the Timika vicinity of southern Irian Jaya. The new species was formerly confused with P. reticulates, which occurs in the vicinity of Lake Ayamaru on the Vogelkop Peninsula of Irian Jaya. The differences between these two species are contrasted and illustrations of each are provided.
Steven Grant: A replacement name (Nomen novum) and neotype designation for Hara malabarica Day, 1865, with notes on related species (Siluriformes), pp. 169-174
A neotype is designated and a replacement name proposed for Hara malabarica Day, 1865. The species is also moved to the family Bagridae, and to the genus Mystus Scropoli, 1777. The identity of Mystus malabaricus (Jerdon, 1849), Mystus montanus (Jerdon, 1849) is discussed in view of misidentifications made previously. The generic placement and validity of Mystus maydelli Rössel, 1964, ad Mystus var. dibrugarensis Chaudhuri, 1913, is also discussed.
