A small wild prawn of the genus Macrobrachium, found in Chiang Rai Province, Northern Thailand has some morphological features resembling four other closely related species, M. lanchesteri, M. peguense, M. kunjuramani, and M. chainatense. However, it is distinguishable from the above species in terms of distinctive golden colored antennules; number of teeth on the rostrum; number of teeth on the cutting edges of the second pereiopod; and length of carpus relative to that of chela on the second pereiopod. Moreover, DNA analysis places it far apart on the phylogenetic tree from the related species in the genus.Okanagana boweni sp. n. is described from the western margin of the Great Basin of North America. The new species is diagnosed from allopatric O. simulata Davis and sympatric O. utahensis Davis using morphological, bioacoustical, and molecular characters. The distribution of this new species coincides with the Walker Lane region that lies along the border of California and Nevada, USA. Based on geography, bioacoustics, morphology, and molecular phylogenetics, we hypothesize that O. boweni sp. n. is the allopatric sister species of O. simulata.A collection of microcaddisflies from sites on the Cuito, Cuanavale, Cuembo, Cuando, Cubango, and Lungue Bungo Rivers in Angola has yielded seven new species and led to new records for a further five species. The new species include Hydroptila cuembica sp. nov., Hydroptila moxica sp. nov., Oxyethira palisada sp. nov., Orthotrichia ferreirae sp. selleck screening library nov., Or. meyi sp. nov., and Or. mlamboi sp. nov., and another species for which we erect a new genus, Aenigmatrichia asymmetrica gen. et sp. nov. The new records are for Catoxyethira kunenica Mey de Moor 2019, Hydroptila brigittae Gibon 1987b, Hydroptila cruciata Ulmer 1912, Hydroptila maoae Gibon, Guenda, Coulibaly 1994, Oxyethira sechellensis Malicky 1993, and a larva identified as that of a species of Tricholeiochiton. Beyond the known Angolan microcaddisfly fauna we resolve several taxonomic problems We refer to Orthotrichia a species described by Jacquemart in Hydroptila, to become Orthotrichia trifurcata (Jacquemart 1962), comb. nov., with Orthotrichia hydroptiloides Wells Andersen 1995 (from Tanzania) as a junior synonym; and we recognise Orthotrichia kivuensis Jacquemart 1956 (from Bukana, on Lake Kivu) as a junior synonym of Or. sanya Mosely 1948a from the Orange and Fish rivers. A list is given of the 16 microcaddisfly species now known from Angola Representation is probably typical of sand and silt-based streams and pools, with the exception of Catoxyethira and Orthotrichia.An annotated checklist for the freshwater fishes from Paraná State, Brazil is provided. A total of 440 freshwater fish species are recorded for the state, distributed across five ecoregions Upper Parana, Lower Parana, and Iguassu, all within the rio Paraná basin, and corresponding to the state's Inland Slope, and Southeastern Mata Atlantica and Ribeira de Iguape, corresponding to the Atlantic Slope, encompassing minor coastal drainages emptying in the Baía de Paranaguá or in the Baía de Guaratuba, and the rio Ribeira de Iguape basin, respectively. The Upper Parana ecoregion ocuppies the larger in area in the state, and is divided into the following sub-ecoregions Floodplain, Paranapanema, Piquiri, and Ivaí. Species richness for each ecoregion is as follows 273 species for the Upper Parana (Paranapanema sub-ecoregion, 217 species; Floodplain sub-ecoregion, 193 species; Piquiri sub-ecoregion, 154 species; Ivaí sub-ecoregion, 132 species), 154 species in the Lower Parana, 127 species in the Iguassu, 68 species in the Southeastern Mata Atlantica, and 50 species in the Ribeira de Iguape. We recorded 42 putatively undescribed species and 117 endemic species from specific ecoregions (except Upper Parana) or sub-ecoregions in the state. Ninety-eight species recorded are non-native from at least one of the state's ecoregions. Thirty-three species are considered threatened. The ecoregions in the Atlantic Slope share many more species with each other than with ecoregions in the Inland Slope. The Iguassu ecoregion is the only one located in Inland Slope that shares more species with the Atlantic Slope than with the remaining ecoregions from the Inland Slope. The Ivaí sub-ecoregion lacks several species that are common to all other sub-ecoregions of the Upper Parana ecoregion. Comments on the historical development of taxonomic knowledge, biogeography, threats, and conservation strategies for the fish fauna from the Paraná State are provided.Recently the classification of the ladybird beetles' tribe Epilachnini was revised based on morphological and molecular data (Szawaryn et al. 2015, Tomaszewska Szawaryn 2016). Based on these findings a new classification of the tribe was proposed. The genus Epilachna Chevrolat in Dejean, 1837 sensu lato was split into several clades, with Epilachna sensu stricto limited to New World fauna, and one of the Afrotropical clades, formerly defined as Epilachna sahlbergi-group (Fürsch 1963), has been named Chazeauiana Tomaszewska Szawaryn, 2015 (Szawaryn et al. 2015), with Epilachna sahlbergi Mulsant, 1850 as the type species. However, that taxon received an unnecessary replacement name, as Mulsant (1850) already described a subgenus of Epilachna named Cleta distributed in Afrotropics, with Epilachna eckloni Mulsant, 1850 as the type species, which also belongs to the E. sahlbergi-group. Consequently Cleta has been elevated to the genus level (Tomaszewska Szawaryn 2016) and Chazeuiana was synonymized with Cleta as a junior synonym. Nonetheless, authors (Tomaszewska Szawaryn 2016) were not aware that the name Cleta is preoccupied. It appeared that Duponchel (1845) established the genus Cleta in the family Geometridae (Lepidoptera) that makes Cleta Mulsant (1850) a junior homonym. Therefore, we propose here Afrocleta nom. nov. as a replacement name for Cleta Mulsant, 1850.A new species of the genus Sulcohumpacris Yin, Yin et Cao, 2017 i.e. Sulcohumpacris wuanensis sp. nov. is described in this paper from China. The new species is similar to Sulcohumpacris hebeiensis Yin, Yin et Cao, 2017 but differs from latter by median keel of pronotum cut by hind sulcus slightly, tegmen of male cover 2/3 tympanum, length of Krauss' organ 1.8 times of width in female, apex of subgenital plate of male point, cercus of male narrow at base, lower margin of Epiphallus with large projection in the middle and hind knee of female not curved at lower margin. Type specimens are deposited in the College of Life Sciences, Hebei University, Baoding, China.
