Three new species of potamonautid freshwater crabs are described from the Lake Victoria region in southern Uganda, East Africa. Two of the new species (Potamonautes busungwe sp. nov. and P. entebbe sp. nov.) are from the shores of Lake Victoria, while the third (P. kantsyore sp. nov.) is from an inland locality on the Kagera River that flows into the lake. In addition, two of the new taxa (P. busungwe sp. nov. and P. kantsyore sp. nov.) are among the smallest species of freshwater crabs so far known from Africa. Diagnoses, illustrations and distribution maps are provided for these taxa, which are compared to similar species from Uganda and elsewhere in East Africa.

Two new species of potamonautid freshwater crabs are described from the Imatong Mountains and Mount Moroto in northern Uganda, East Africa, and a third highland species, Potamonautes amalerensis (Rathbun, 1935) stat. rev. from Mount Kadam is re-diagnosed based on examination of the holotype. All three species are endemic to a different mountain range and their collection localities indicate a distinct preference for higher altitudes. Diagnoses, illustrations and distribution maps are provided for these taxa, and they are compared to similar species from the region. The conservation status of all three species is discussed.

Two new genera, Sylvathelphusa n. gen. and Tzotzilthelphusa n. gen., and three new species, Sylvathelphusa kalebi n. sp., S. cavernicola n. sp. and Tzotzilthelphusa villarosalensis n. sp., of the tribe Potamocarcinini, family Pseudothelphusidae, are described from Chiapas, Mexico. Sylvathelphusa n. gen. is characterized by a male gonopod with the marginal plate between the caudal and mesial surfaces abruptly widening distally and forming a triangular apical projection; and a mesial process as a strong, acute spine forming a 90º angle with respect to the principal axis of the gonopod. Tzotzilthelphusa n. gen. exhibits a male gonopod strongly bent laterally in the distal third, and a mesial surface rounded distally with acute spinules. Sylvathelphusa n. gen. is similar to Potamocarcinus in gonopod morphology, in both straight and with a mesial process developed as strong tooth in a similar shape and position. Tzotzilthelphusa n. gen. is similar to Phrygiopilus in that the gonopods of both genera develop a supra-apical process that is a continuation of the mesial surface. The new taxa come from the Los Altos de Chiapas region and bring the total number of pseudothelphusid genera in Chiapas to 11.

The taxonomy of three morphologically related and endemic genera of the northern Western Ghats (Ghatiana Pati & Sharma, 2014, Gubernatoriana Bott, 1970, and Inglethelphusa Bott, 1970) is re-assessed to accommodate several new taxa. We describe a new genus, Sahyadriana gen. nov. and its five new species [S. billyarjani sp. nov., S. pachyphallus sp. nov., S. sahyadriensis sp. nov. (type species), S. tenuiphallus sp. nov., and S. woodmasoni sp. nov.]. Additionally, three new species each of Ghatiana (Gh. botti sp. nov., Gh. pulchra sp. nov., and Gh. rathbunae sp. nov.) and Gubernatoriana (Gu. longipes sp. nov., Gu. marleshwarensis sp. nov., and Gu. wallacei sp. nov.) are described. Five species previously in Gubernatoriana are now transferred to Sahyadriana gen. nov., viz. S. alcocki (Pati in Pati, Thackeray & Khaire, 2016) comb. nov., S. pilosipes (Alcock, 1909) comb. nov., S. thackerayi (Pati in Pati, Thackeray & Khaire, 2016) comb. nov., S. triangulus (Pati & Sharma, 2014) comb. nov., and S. waghi (Pati in Pati, Thackeray & Khaire, 2016) comb. nov. Gubernatoriana basalticola Klaus, Fernandez & Yeo, 2014, is transferred to Ghatiana. Inglethelphusa is still proved to be monotypic. Consequently, Ghatiana now contains eight species, three of which are new; Gubernatoriana, four species, including three new species; Inglethelphusa, one species; and Sahyadriana gen. nov., ten species, including five new species. Sahyadriana pilosipes is rediscovered more than a century after its description. All these genera can be separated from other Indian gecarcinucid crabs by the absence of a flagellum on the exopod of the third maxilliped and a very short G2. The relevant identification keys are revised. Currently, 120 species of freshwater crabs under 35 genera and two families are found in India. Kerala is the most species-rich (35 species) state in India followed by Maharashtra (29 species) and Assam (21 species). The Western Ghats of India now includes 17 genera and 58 species of gecarcinucid crabs. A checklist and distribution of Indian freshwater crabs is provided.

Since the publication of the Solanaceae treatment in “Flora Argentina” in 2013 exploration in the country and resolution of outstanding nomenclatural and circumscription issues has resulted in a number of changes to the species of the Morelloid clade of Solanum L. (Solanaceae) for Argentina. Here we describe three new species: Solanum hunzikeri Chiarini & Cantero, sp. nov., from wet high elevation areas in Argentina (Catamarca, Salta and Tucumán) and Bolivia (Chuquisaca and Tarija), S. marmoratum Barboza & S. Knapp, sp. nov., from central Argentina in Catamarca, La Pampa, La Rioja, San Juan and San Luis, and S. tiinae Barboza & S. Knapp, sp. nov., from the mountains of Jujuy, La Rioja, Salta and Tucumán. We provide descriptions, illustrations and distribution maps for all new taxa. A table of nomenclatural changes and additional taxa now known to occur in Argentina summarizes additions and changes since the “Flora Argentina”. We also provide an updated key, including all new taxa for the country, to facilitate identification and further exploration.

1. Three new species of Myxosoma (Sporozoa, Cnidosporidia, Myxosporidia) are described from freshwater fish of the genus Tilapia in East Africa.2. Two of these, M. heterospora and M. brachyspora spp.nov., inhabit the abdominal viscera: the former was found in 41 of 43 fish examined, while the latter was less common. The third species, M. homeospora sp.nov., produces small oval or circular ‘cysts’ in the subdermal muscle and was found in two very young fish only. Spores resembling those of the first two species were also found in one Haplochromis sp.3. The spores of M. heterospora are roughly ellipsoidal but are very variable in shape, and range from 8·5–17·0 μ in length and 6·3–11·0 μ in breadth; the two anterior polar capsules measure from 2·0–9·5 by 1·5–3·5 μ. Those of M. brachyspora are flattened antero-posteriorly, measuring from 7·0–7·5 μ long and 12·0–13·5 μ broad; their polar capsules are from 2·5–3·8 by 2·3–2·5 μ in size. M. homeospora has ovoid spores with the anterior end narrowed, measuring from 13·5–17·0 by 8·5–11·0 μ; the polar capsules measure 4·0–6·0 by 2·0–4·0 μ.4. It is suggested that M. heterospora, at least, is pathogenic and may play a considerable part in reducing the availability of fish as food in this part of Africa.5. A check-list is given of all species of the genus Myxosoma.I thank Mr R. S. A. Beauchamp (then Director of E.A.F.R.O.) and his staff, also Mr G. Bowser (Manager of TUFMAC), for facilities and assistance in the examination of fish; also Dr G. D. Fryer and Dr D. J. Garrod for sending material to me in London, and Dr P. H. Greenwood for supplying the Haplochromis and checking the names of fish; also Messrs G. D. Lomax and P. E. Nesbitt for the preparation of sections. This work was commenced while I was employed at the East African Trypanosomiasis Research Organization.

A consultation of the original descriptions of the genera of Scissurellidae led the author to conclude that the valid names for the genera of this family are: Scissurella d'Orbigny, 1823 (redescription by Sowerby, 1824), Anatoma Woodward, 1859, Inoisura Hedley, 1904, Scissurona Iredale, 1924, Sinezona Finlay, 1927. Scissurella and Anatoma are cosmopolites, the first generally living in shallow waters, associated to sea-weeds, while the second is found in deep waters. The three last genera are restricted to Australasia. Three new species are described from the Brazilian coast: Soissu rella alexandrei, Scissurella eleotilis and Scissurella morretesi. The internal anatomy of S. alexandrei is described. These three new species have been found in littoral shallow waters, the two first on the northeast Brazilian coast, the third on the coast of the State of São Paulo. The fourth known species of Scissurellidae from Brazil, Anatoma aedonia (Watson, 1886), was dredged by H.M.S, "Challenger", in 1873, off Pernambuco, 350 fm (640 m).
