Abstract The Neotropical freshwater cladoceran Bergamina lineolata (Sars, 1901) was found in a small temporal pond in the Magdalena department. Hitherto, it has been reported in Brazil and El Salvador. It was originally described as Alonella lineolata by Sars, 1901 from Brazil and then placed to the genus Bergamina by Elmoor-Loureiro et al. (2013). This is the first record of this species in Colombia. B. lineolata can be identified by a unique combination of characters including: 1) a remarkably large and oblong postabdomen, with three denticles on distal corner; 2) basal spine of the claw very short, length less than the half claw diameter at base; 3) IDL with two setae shorter than ODL seta, armed with fine setules unilaterally in terminal half; 4) endite 1 of trunk limb I with a long smooth seta between endites 1 and 2.

Rybocyclops Dussart, 1982 is a little-known stygobitic genus, hitherto represented by its type and only species, R. pauliani (Lindberg, 1954), from Madagascar. A second species, named Rybocyclops dussarti sp. nov., is described herein from an agricultural bore-well in southeastern India. The new species has a unique combination of morphological characters, which, inter alia, include: genital double-somite enlarged; anal operculum moderately large; furcal rami somewhat outcurved and about twice as long as wide; female antennules 11-segmented; legs 1–4 with spine formula 2.2.2.2, and setal formula 5.5.5.4; legs 1 and 4 without seta on inner margin of coxa and basis; leg 4 male with one seta more than in female on second endopodal segment; leg 5 fused to somite and represented by vague protuberance, bearing three setae; and leg 6 reduced to two setae. The generic diagnosis is partially amended for accommodating the new species. The discovery of R. dussarti sp. nov. is of much biogeographic interest because it is the first record of Rybocyclops from Asia and only the second freshwater stygobitic cyclopoid taxon from India, with apparent Gondwanan distribution.

A New Species

A taxonomic survey of Marphysa species (Polychaeta: Eunicida: Eunicidae) from coastal regions of northern Australia including recently collected specimens from a fish farm near Darwin, yielded three species: M. mullawa Hutchings & Karageorgopolous, 2003, a first record from northern Australia; M. mossambica (Peters, 1854; was Nauphanta mossambica), first confirmed record from Australia; and a new species, M. fauchaldi. The new species was recorded from intertidal muddy shores as well as in the sediments of fish farm ponds, where it was extremely abundant. It is characterised by a unique combination of chaetal features. A newly proposed informal subgroup of Marphysa, the Teretiuscula-group, is erected to contain the new species and other Marphysa species that share the possession of compound spinigerous chaetae in anterior parapodia only and the peculiar behaviour of encapsulating embryos in jelly cocoons. Morphologically, the new species falls between a group of Marphysa species having only compound spinigers and the recently resurrected genus Nauphanta, which completely lacks compound chaetae. The discovery of this new species necessitated a re-evaluation of the morphological features of Nauphanta and Marphysa species lacking falcigers, in particular homology of fan chaetae, the only apparent synapomorphy of Nauphanta. Fan chaetae appear to be a specialised type of pectinate chaetae, which are found also in species of Marphysa including the new species. Based on this finding, and an evaluation of other characters, Nauphanta is returned to synonymy with Marphysa. Further, an analysis of size-related variation of key morphological characters in M. mossambica and comparison with those in the types of M. novaehollandiae (Kinberg, 1865; formerly Nauphanta) and M. simplex Treadwell, 1922, indicated that both species should be synonymised with M. mossambica. A key is provided to identify Marphysa species of the Indo-west Pacific.

Homalometron moraveci n. sp. is described from the yellowfin goatfish, Mulloidichthys vanicolensis, from the waters off New Caledonia and from the Swain Reefs of the Great Barrier Reef. Its unique combination of narrow, elongate body and long hermaphroditic duct reaching well into the hindbody, distinguish this species from all other species of Homalometron. A checklist of species of digeneans reported in species of Mulloidichthys shows that most of the records are of members of the Opecoelidae and this is the first record of an apocreadiid from this host genus.

Polkepsilonema arabicensis sp. n. is discovered from the coralline sand of Lakshadweep island, located off the south-western coast of India. The species differs from other congeners by its unique combination of characters: presence of fine spines along the body curvatures, 5–6 rows of bisinuous ambulatory setae, male with two clusters of ventral copulatory thorns and 14 subcephalic sensilla. The novel species is the fourth discovery of the genus and first record from the coastal areas of Indian subcontinent. A key to species level is provided.

We report here the first record of five genera of Spongillida (Porifera, Demospongiae) in both lentic and lotic water of Madagascar and the discovery of a new species of the genus Corvospongilla from the Betsiboka River hydrographic basin. Corvospongilla lemuriensis sp. n. diverges from all the other known species of the genus in its unique combination of diagnostic morphotraits (a) sessile gemmules with chambered pneumatic layer within tri-layered theca and enveloped by spicular cage of dominant acanthostrongyles, (b) dominant acanthostrongyles and less frequent acanthoxeas-strongyloxeas as megascleres and gemmuloscleres. The new species is characterised by the exclusive presence of a well-developed pneumatic layer in sessile gemmules not described for the genus until now. The new record confirms a Gondwanian track for the genus Corvospongilla and increases the knowledge on Spongillida historical biogeography. In synthesis the present discovery of Corvospongilla in the Malagasy biogeographic province (a) contributes to the assessment of Afrotropical biodiversity, (b) enlarges the geographic range of the genus reducing its disjunct distribution, and (c) focus on the evolutionary history of adaptive morphofunctional traits of resting bodies and life cycle timing in ephemeral water of the south-eastern Austral hemisphere.

We review and summarize present knowledge of the western Central African toad genus Werneria, and describe two new species. Both new species seem to be more closely related to W. mertensiana, W. tandyi and W. preussi than to W. bambutensis. Werneria submontana nov. sp., from Mt. Kupe and the Bakossi Mts., Cameroon, is unique in having a wrinkled throat skin in adults and has a unique combination of other morphological and colour characters. Werneria iboundji nov. sp. is only known from its type locality, Mt. Iboundji, and represents the first record of this genus from Gabon. It is characterized by extensive webbing of the toes, slender, almost straight body shape, truncate snout, and colour.

AbstractBased on the known fossil record, the majority of crocodylians from the Cenozoic Era of Australia are referred to the extinct clade Mekosuchinae. The only extant crocodylians in Australia are two species of Crocodylus. Hence, the viewpoint that Crocodylus and mekosuchines have been the only crocodylians inhabiting Australia during the Cenozoic has remained largely undisputed. Herein we describe Australia’s first tomistomine crocodylian, Gunggamarandu maunala gen. et sp. nov., thus challenging the notion of mekosuchine dominance during most of the Cenozoic. The holotype specimen of Gunggamarandu maunala derives from the Pliocene or Pleistocene of south-eastern Queensland, marking the southern-most global record for Tomistominae. Gunggamarandu maunala is known from a large, incomplete cranium that possesses a unique combination of features that distinguishes it from other crocodylians. Phylogenetic analyses place Gunggamarandu in a basal position within Tomistominae, specifically as a sister taxon to Dollosuchoides from the Eocene of Europe. These results hint at a potential ghost lineage between European and Australian tomistomines going back more than 50 million years. The cranial proportions of the Gunggamarandu maunala holotype specimen indicate it is the largest crocodyliform yet discovered from Australia.

A new species of a presumably karst dwelling Rock Gecko, Cnemaspis laoensis sp. nov., is described from Dong Phu Vieng National Protected Area, Savannakhet Province, Laos. Cnemaspis laoensis is differentiated from all other Southeast Asian Cnemaspis in having a unique combination of color pattern (in alcohol) and scale characteristics. Cnemaspis laoensis is the first record of Cnemaspis from Laos and extends the range of this genus approximately 600 km to the northeast. Its presence in Laos underscores the need for continued exploration of karst habitats throughout Indochina were Cnemaspis commonly occur.

Only six species (four genera, one family) of freshwater sponges are known until now from Thailand. A first record of thegenus Corvospongilla Annandale, 1911 with the description of a new species is here reported from the Pong River in the LowerMekong Basin. The taxonomic status of Corvospongilla siamensis nov. sp. is discussed in comparison to the 18 speciesassigned to the genus. The new species is characterised by i) alveolate, paucispicular skeletal network with scanty spongin,thick ascending tracts towards the sponge surface to support conules; ii) skeleton of stout microspined strongyles, andextremely rare, abruptly pointed oxeas usually with a few tubercles, plus micropseudobirotules with smooth shaft; iii) gem-mules belonging to a single gemmular morph, typically sessile; iv) gemmular cage notably stout, of tangentially arrangedstrongyles of variable length from tubercled to spiny; v) gemmular theca with abundant laminar compact spongin, lackingpneumatic layer, armed by short, tubercled to spiny strongyles tangentially embedded; vi) larvae armed by spiny oxeas. Corvo-spongilla siamensis nov. sp. differs from all the other known species of the genus in its unique combination of diagnostic traits,particularly a) acanthostrongyles (megascleres), b) gemmuloscleres, both in the cage and in the theca, as strongyles showing the tendency towards ring-shape and button-like shape, and c) larval spiny oxeas.
