Some Brazilian specimens previously assigned to Discoporella umbellata var. conica are re-assigned to D. salvadorensis. The species studied here frequently co-occur on mainly sandy and muddy bottoms at 8-130 m depth, as it is typical of most living populations of cupuladriids. The sedimentation rate, and thus the bottom composition, likely influence the distribution of cupuladriids in Brazil, with Cupuladria species being more common in stabler and coarser sea bottoms than Discoporella species, which tend to be more broadly distributed.During the 2013 Singapore Strait International Marine Biodiversity Workshop, hundreds of ascidians were collected along with numerous other marine phyla. Collections were made intertidally as well as subtidally by snorkel, SCUBA, trawling and dredging. While many ascidian specimens remain unidentified, 14 aplousobranchs, nine phlebobranchs and 17 stolidobranchs have been identified; a surprising 50% of these comprise 20 new records for Singapore. An additional new record of the phlebobranch Perophora namei collected from the same area in 2014 and 2015 is included here. Of the 21 new records, Aplidium cf. grisiatum, Distaplia regina, Euherdmania cf. digitata, Cnemidocarpa irene, Monandrocarpa monotestis and Polyandrocarpa rollandi are also first records for the entire South China Sea region.A new species of the genus Tactusa Fibiger, 2010, T. motuoensis sp. n. is described from the Autonomous Region Xizang (Tibet), China. Key to the species of the genus Tactusa in China, based on the male genitalia is presented. Eight species of Tactusa referred for China.In this paper we describe a new species of Adelius (Braconidae, Cheloninae) from the Afrotropical region, the first record of the genus for Angola, and a significant extension of its geographical distribution.'Nemacheilus' argyrogaster, new species, is described from the Xe Kong, Mekong drainage, in Attapeu and Xe Kong provinces, southern Laos. It is distinguished from all other Nemacheilidae in Southeast Asia by its unique colour pattern made of a bold black midlateral stripe separating the yellowish brown dorsal part of the body from the silvery whitish ventral part and a middorsal row of 14-19 thin saddles. Besides, the male has a globulous suborbital flap with tubercles along its free, posterior edge, and the pectoral fin with thickened anterior ray and branched rays 1-4 and unculiferous pads behind them covered by small tubercles; lips thin, lower lip continuous with a narrow median notch. It was found in moderate to fast flowing water, over pebble to stone bottom. https://www.selleckchem.com/EGFR(HER).html 'Nemacheilus' argyrogaster, was earlier misidentified as N. longistriatus; it is provisionally placed in the genus Nemacheilus.A new species of the cosmopolitan jellyfish genus Aurelia is described from the coastal waters of Mozambique using a combination of morphological, meristic and genetic information (COI and 18S). The species can be separated from congeners that have been recently described by a combination of bell shape, number of canal origins and anastomoses, and the shape of the manubrium and oral arms. Three types of nematocysts are present in the tissues of both the bell margin and oral arms, and this description of the cnidome will allow for future comparison. Pairwise genetic comparisons showed a mean COI divergence of 4.8% within the group, and a mean divergence ranging between 15% and 22% with all other species of Aurelia.The present study addresses the distribution of Mangelia species along the Turkish coasts. The studied material was collected during the last two decades from different habitats (soft and hard bottoms, and macrophyte beds) at depths ranging from the intertidal zone to 1000 m at stations along the Levantine, Aegean and Black Seas coasts of Turkey, and from the Sea of Marmara. Among the analyzed benthic material, 311 living specimens and 114 shells belonging to 18 species of the genus Mangelia were obtained. Mangelia vanaartseni is described as a new species. Among the recognized species, Mangelia unifasciata (Deshayes, 1835) is the most widely distributed species in the study area, while Mangelia secreta (Van Aartsen Fehr-de Wal 1978), Mangelia pallaryi (Nordsieck 1977) and Mangelia striolata Risso 1826 were the rarest ones. Mangelia costata (Pennant 1777) and Mangelia costulata Risso 1826 were found to occur at depths up to 200 m, while most other species occurred at shallower depths. Along with the description of the new species, ecological and distributional characteristics and figures of specimens are also provided.We show that the Wotjulum frog, Litoria watjulumensis (Copland, 1957), comprises two deeply divergent mitochondrial DNA lineages that are also reciprocally monophyletic for a nuclear gene locus and have discrete distributions. The taxa are differentiated in multivariate analysis of shape but show no appreciable differences in colour and pattern. The two taxa differ substantially in the degree of female biased sexual size dimorphism, with the western taxon showing considerably more pronounced dimorphism. We subsequently resurrect Litoria (Hyla) spaldingi (Hosmer, 1964) for populations from east of the Daly River system in the Northern Territory through to western Queensland and restrict L. watjulumensis to populations from the Kimberley region of north-western Australia and the Victoria River system of the western Northern Territory. The complex advertisement call of L. spaldingi is described for the first time.A new peculiar, spiky, and yellowish species of the genus Tegotettix Hancock, 1913 is described from the Davao region of the island of Mindanao (the Philippines)-T. derijei sp. n. (Mindanao horned pygmy devil). The species is visually similar to T. cristiferus (Günther, 1935) from Borneo and T. armatus Hancock, 1913 from Borneo, which is the type species of the genus, and of which a new record from Sabah is also presented in the study. The new species is also similar to an undescribed species from Bukidnon, which we presented by photographs in its natural habitat. To date, T. armatus was known only from old descriptions and drawings and has not been reported for more than 100 years. A brief overview of the species of the genus Tegotettix, with its division into three species groups, is presented.
