According to the study of summer phytoplankton of the Ob River, 153 new species and intraspecific taxa(SIT) of algae from 8 divisions were found, including Cyanoprokaryota – 14, Dinophyta – 2, Chrysophyta – 17, Xantophyta –6, Euglenophyta – 34, Bacillariophyta – 2, Chlorophyta – 72, Charophyta – 6. New taxa are dominated by small-cell greenalgae, phytoflagellates and non-heterocyst cyanoprokaryotes. The intensive succession of the phytoplanktocenosis speciescomposition and the taxonomic structure of the new SIT algae are signs of anthropogenic eutrophication.

Review of specimens and names of Faramea Aubl. (Rubiaceae, Coussareeae) has required new nomenclatural combinations, clarified the identities of some previously described species, and discovered some new taxa. Here we transfer two Faramea names, F. suaveolens Duchass. and F. panurensis Müll. Arg., to Coussarea Aubl.; review the identities of F. cuencana Standl., F. multiflora A. Rich., F. oblongifolia Standl., F. parvibractea Steyerm., F. spathacea Müll. Arg. ex Standl., and F. suerrensis (Donn. Sm.) Donn. Sm.; lectotypify F. multiflora and F. panurensis; transfer to Faramea and lectotypify Rudgea scandens K. Krause; and describe 13 new species and two new subspecies: F. camposiana C. M. Taylor of Ecuador and Peru, F. foreroana C. M. Taylor of Colombia, F. fosteri C. M. Taylor of western South America, F. galerasana C. M. Taylor of Ecuador, F. grayumiana C. M. Taylor of Central America, F. kampauicola C. M. Taylor of Ecuador and Peru, F. neilliana C. M. Taylor of western South America, F. premontana C. M. Taylor of Ecuador, F. quijosana C. M. Taylor of Ecuador, F. ramosiana C. M. Taylor of Colombia, F. reyneliana C. M. Taylor of Peru, F. stoneana C. M. Taylor with two subspecies from Central and western South America, F. suerrensis subsp. miryamiae C. M. Taylor from Colombia, and F. vernicosa C. M. Taylor of Ecuador and Peru.

AbstractA new lichen species is described from specimens growing on Fraxinus trees north of Eindhoven (the Netherlands). Morphological and genetic studies suggest that the new species belongs in the genus Catillaria, and the name Catillaria flexuosa is proposed because of its flexuose apothecia. The new species is characterized by the relatively large apothecia (up to 0.9 mm diam.) and relatively thick, knobby to ±subsquamulose, greenish, thallus. Due to their similar morphological features, C. flexuosa can be easily confused with Catillaria chalybeia, C. fungoides or C. nigroclavata, so it is therefore compared with these species. In addition, Arthonia epiphyscia is reported being a very rare species in the Netherlands.

Liopeltis is a genus of poorly known, infrequently sampled species of colubrid snakes in tropical Asia. We collected a specimen of Liopeltis from Pulau Tioman, Peninsular Malaysia, that superficially resembled L. philippina, a rare species that is endemic to the Palawan Pleistocene Aggregate Island Complex, western Philippines. We analyzed morphological and mitochondrial DNA sequence data from the Pulau Tioman specimen and found distinct differences to L. philippina and all other congeners. On the basis of these corroborated lines of evidence, the Pulau Tioman specimen is described as a new species, L. tiomanica sp. nov. The new species occurs in sympatry with L. tricolor on Pulau Tioman, and our description of L. tiomanica sp. nov. brings the number of endemic amphibians and reptiles on Pulau Tioman to 12.

Eight new taxa of Eriophyidae mites associated with native trees in the Cupania genus—C. oblongifolia Mart. and C. impressinervia Acev (Sapindaceae)—from the Atlantic Forest in Brazil, are described and illustrated. They include two new genera and two new species of Nothopodinae, Colopodacini (Setibia domatiagena   gen. nov., sp. nov. and Aricolopodos alagoensis gen. nov., sp. nov.), one new genus and two new species of Cecidophyinae, Colomerini (Euryslobos keronidos gen. nov., sp. nov. and Gammaphytoptus cupanius sp. nov.), and one new species of Phyllocoptinae, Tegonotini (Shevtchenkella caboata sp. nov.).

Abstract We describe two new species of the freshwater-crab genus Demanietta  Bott, 1966 from Tanintharyi (Tenasserim) division, southern Myanmar (Burma), Demanietta liui  sp. nov. and Demanietta lenya  sp. nov.  Demanietta liui  sp. nov. is morphologically most similar to D. thagatensis  Rathbun, 1904 and D. khirikhan  Yeo, Naiyanetr & Ng, 1999; D. lenya  sp. nov. appears close to D. manii  Rathbun, 1904, D. merguensis  Bott, 1966, and D. nakhonsi  Yeo, Naiyanetr & Ng, 1999. The two new species are easily distinguished from their most similar congeners in the shape of the external orbital tooth, epibranchial tooth, and male first gonopod. Molecular analysis based on partial mitochondrial 16S rDNA also supports the systematic position of the new taxa.

A new species and eight new subspecies of Papilionoidea discovered in Vietnam between 2002 and 2020 are described and illustrated. The status of two taxa are revised. New taxa include Pieridae: Delias sanaca bidoupa Monastyrskii & Vu subspec. nov. and Talbotia naganum aurelia Monastyrskii & Vu subspec. nov.; Nymphalidae: Abrota ganga pulcheria Monastyrskii & Vu, subspec. nov.; Bassarona recta consonensis Monastyrskii & Vu, subspec. nov.; Pantoporia bieti aurantina Monastyrskii & To subspec. nov.; Ragadia latifasciata cristata Monastyrskii & Vu, subspec. nov.; Ragadia latifasciata crystallina Monastyrskii & Vu, subspec. nov.; Faunis indistincta luctus Monastyrskii & Vu subspec. nov. & Aemona gialaica Monastyrskii, K. Saito & Vu, spec. nov. The taxon infuscata Devyatkin & Monastyrskii, previously described as the subspecies Aemona tonkinensis infuscata, was elevated to the species level, while the taxon critias (Ragadia critias Riley & Godfrey) was reduced to a subspecies. Three Satyrinae species were recorded from Vietnam for the first time: Palaeonympha opalina Butler, 1871; Ypthima motschulskyi Bremer & Grey, 1853; and Ragadia latifasciata Leech, 1891.

The status of the genus Phelene stat. resurr., previously synonymized under Chiriquia is revalidated. The genus is redescribed and Phelene turgida stat. rev. a lectotype and paralectotypes are designated for this species. Tetrix laticeps is proposed as nomen dubium and its described a new additional species Phelene maroon n. sp. The diagnosis of the subfamily is adjusted with the characters of the new taxa included and an updated key of genera and species is provided.

New taxa and synonymies in the group of Liptena opaca (Kirby, 1890) (Lepidoptera, Lycaenidae, Poritiinae). A lectotype of Liptena opaca (Kirby, 1890) is designated, and the status of three of its subspecies are revised: ugandana Stempffer, Bennett & May, 1974, is raised to specific rank, centralis Stempffer, Bennett & May, 1974, is synonymized with L. opaca gabunica, and sankuru Stempffer, Bennett & May, 1974, becomes a subspecies of L. albomacula Hawker-Smith, 1933. Liptena ouesso Stempffer, Bennett & May, 1974, is synonymized with L. immaculata Grünberg, 1910. Six new species are described, four from Cameroon (L. arnouxi n. sp., L. laguerrei n. sp., L. mariae n. sp. and L. perconfusa n. sp.), one from eastern Nigeria (L. brophyi n. sp.), and one species (L. restricta n. sp.) as well as a new subspecies (L. immaculata orientis n. ssp.) from north-eastern Democratic Republic of the Congo.

Six new species of the genus Cenophengus LeConte, 1881 are described. Five of these new species were collected in Mexico, in the states of Hidalgo (Cenophengus mboi sp. nov. and Cenophengus hnogamu̱i sp. nov.), Coahuila (Cenophengus kikapu sp. nov.) and San Luis Potosí (Cenophengus tupae sp. nov., Cenophengus mumui sp. nov.). An additional species was collected in Puerta Parada, Guatemala (Cenophengus xiinbali sp. nov.). The new taxa described in the present study increase to 27 the number of species assigned to Cenophengus.
