Two new species of small-sized terrestrial toad of the genus Melanophryniscus from the highland grasslands of the Ventania and Tandilia Mountain Systems in Buenos Aires province, Argentina, are described. We assign provisionally Melanophryniscus diabolicus sp. nov. (Ventania mountains) and Melanophryniscus nigricans sp. nov. (Tandilia mountains) as both belonging to the Melanophryniscus stelzneri group. The new species differs from other congeners by a distinctive combination of characters: dorsum dark black, tympanum concealed, venter blackish, and distribution on highland rocky grasslands in the mountains of Tandilia (M. nigricans sp. nov.), and on highland rocky grasslands in the mountains of Ventania and coastal dune grassland (M. diabolicus sp. nov.). Moreover, the advertisement call of the new species is noticeable different between species and close related species M. atroluteus and M. montevidensis. Both species have experienced local extinctions and should be categorized as threatened species.

Three new species of paramunnid isopods are described:Pentaceration pleonarietissp. nov.,Neasellus argentinensissp. nov. andN. bicarinatussp. nov. The three species were collected off Buenos Aires province, the last one was also collected off Chubut province, Argentine Sea. The species belonging toPentacerationrepresents the first record of this genus in the Argentine Sea. The diagnostic characters of the genusNeasellusare revised and besides the inclusion of the two new species herein described, a new combination for the speciesPelagogonium oculatumSchultz, 1977 is proposed.

This paper continues the publication of new data obtained during field studies in remote and poorly studied regions of Laos in 2015–2018. It provides descriptions of two new species (Bulbophyllum brachyscapum Aver. and Sunipia saccata Aver.), emended descriptions of two previously published but insufficiently known species (Cleisostoma verrucosum Aver., Oberonia vesiculifera Aver.) and reports of eight species newly recorded in the flora of Laos (Biermannia calcarata Aver., Bulbophyllum farreri (W. W. Sm.) Seidenf., Didymoplexiella trichechus (J. J. Sm.) Garay, Eria eriopsidobulbon C. S. P. Parish et Rchb. fil., Habenaria ciliolaris Kraenzl., Liparis caudata Aver. et K. S. Nguyen, Odontochilus umbrosus (Aver.) Ormerod, and Porpax ustulata (C. S. P. Parish et Rchb. fil.) Rolfe). Appropriate citations of regional literature, colour illustrations, data on types and distribution, descriptions, etymology, as well as notes on taxonomy and related species are provided for the studied species.

The genus Agrotera Schrank, 1802 is revised for Australia and the generic definition is refined based on the male genitalia. The genera Leucinodella Strand, 1918 stat. rev. with L. leucostola (Hampson, 1896) comb. nov., Nistra Walker, 1859 stat. rev. with N. coelatalis Walker, 1859 comb. rev., Sagariphora Meyrick, 1894 stat. rev. with S. magnificalis (Hampson, 1893) comb. nov., and Tetracona Meyrick, 1884 stat. rev. with T. amathealis (Walker, 1859) comb. rev. and T. pictalis Warren, 1896 comb. rev. are removed from synonymy with Agrotera, as they lack the synapomorphies of Agrotera. Two new species, Agrotera genuflexa sp. nov. from Northern Territory, Queensland and New South Wales, and A. longitabulata sp. nov. from Queensland, are described. The taxonomic status of the Australian species of Agrotera is discussed, and a key to all species, based on males, is provided. The adults and genitalia of the new species and some related species are figured.

AbstractThe Aschistodesmini from the Solomon Island are reviewed. Besides clarifying notes on the status of the type and closely related species of Aschistodesmus, descriptive notes and illustrations of the gonopods of the Solomon species of this genus, particularly of those published by Chamberlin, 1920, under the generic name of Solomonosoma, are given. Two new species, A. spatulifer and A. tridentifer are described, and a key to the species is provided. From Rennell Island Dorcadogonus modestus gen. n., sp. n. is described.

Two new species, Sinoarinia feii Chen, gen. et sp. nov. and Pincerna vallis Chen & Wu, sp. nov., are described from western Hubei, China. The new genus Sinoarinia Chen & Wu, gen. nov. is established based on the strongly constricted penultimate whorl and the ascending last whorl. The Vietnamese species Pincerna costulosa (Bavay & Dautzenberg) is newly reported from Yunnan, China. For comparison, photographs of the shells of closely related species are provided. A key to the known species of Sinoariniagen. nov. is included.

In the present study, two new species of Nitzschia Hassall, Nitzschia pusilluhasta sp. nov. and Nitzschia australodesertorum sp. nov. are described from reservoirs in the state of São Paulo southeast Brazil. The morphology of the new species was analysed using light and electron microscopy. Nitzschia pusilluhasta is distinguished from morphologically related species by its valve outline, the shape of apices and fibulae, the absence of a gap between central fibulae, and the density of striae and areolae. Nitzschia australodesertorum differs from morphologically similar species in its valve outline, the shape of apices and fibulae, the presence of a gap between the central fibulae, and the density of fibulae and striae. The morphology and ecology of the new species are discussed and compared with morphologically related taxa. Information on the co-occurrence of other diatom species in the samples is also provided.
