A new dipluran species, Plusiocampa (Plusiocampa) imereti Sendra & Barjadze sp. nov., from the deep zone in three caves in the Imereti region, Georgia, is described. This new troglobitic Plusiocampa is an addition to four others known Diplura from around the Black Sea region, two Dydimocampa and two Plusiocampa s. str. The present study also provides the first CO1 sequences for the Plusiocampinae taxa and the first molecular data for cave-dwelling Plusiocampa species. Although bootstrap values were low, the maximum-likelihood phylogenetic tree grouped Plusiocampa (P.) imereti Sendra & Barjadze sp. nov. with two Plusiocampa s. str. species from Eastern Europe. Morphologically, P. (P.) imereti Sendra & Barjadze sp. nov. is closely related to two cave-dwelling species: Plusiocampa (Plusiocampa) glabra Condé, 1984 and Plusiocampa (P.) chiosensis Sendra & Gasparo, 2020. The new species can be distinguished by the presence of lateral anterior macrosetae on metanotum, more uneven claws, and the presence of 2+2 lateral anterior macrosetae on middle urotergites. The five species currently known for the Black Sea region inhabit caves located at low altitude but with no influence from former glacial or permafrost processes.

Marine caves possess unique biocoenotic and ecological characteristics. Sessile benthic species such as sponges associated with cave habitats typically show a marked zonation from the cave entrance towards the end of the cave. We describe three semi-submerged karstic caves of 50 to 83 m length and 936 to 2,291 m3volume from the poorly explored cavernicolous fauna of North-East Bulgaria. We surveyed sponge diversity and spatial variability. Eight demosponge species were identified based on morphological and molecular data, of which six are known from the adjacent open sea waters of the Black Sea. Two species,Protosuberites denhartogivan Soest & de Kluijver, 2003 andHalichondria bowerbankiBurton, 1930, are reported from the Black Sea for the first time. The spatial sponge distribution inside the caves is in general similar, but shows some differences in species composition and distribution depending on cave relief and hydrodynamics. The species composition of sponges of Bulgarian caves is found to be different from Crimean caves. An updated checklist of the Black Sea sponges is provided.

Morphological And Molecular Data

Two new species of Limnichidae beetles, Byrrhinus negrosensissp. nov. and Byrrhinus villarinisp. nov., are described from the Island of Negros in the Philippines. The adult specimens of the new species can be differentiated by patterns of body punctation, colour and orientation of elytral pubescence, posterolateral angle of pronotum, tarsomere length ratio and aedeagal form. Two clades, representing the two new species, were retrieved in the Maximum Likelihood gene tree using the 3’-end of the COI gene. Maximum genetic divergence within B. negrosensis sp. nov. and B. villarini sp. nov. were recorded to be 2.3% and 1.3%, respectively, while the mean interspecific divergence between the two new species was 19.7%. Morphological descriptions, digital photographs and COI sequences were provided for the two species. The state of knowledge of Byrrhinus is reviewed and an updated Philippine checklist is provided. By coupling morphological and molecular data, this paper provides the first additional new species of Philippine Byrrhinus in the last 28 years.

Scenedesmus Almeriensis

The microalga Tetradesmus almeriensis, previously known as Scenedesmus almeriensis, has been isolated and cultivated as a highly productive, fast-growing strain known as a natural source of different products of commercial interest, including bioactive compounds such as lutein. This strain produces up to 40 g·m−2·day−1 of lutein under optimal conditions and is highly recommendable for outdoor production in temperate and warm climates, showing maximal performance at temperatures up to 35 °C with no photo-inhibition taking place with irradiances greater than 1000 μE·m−2·s−1. Morphological and molecular data allow its assignment to the Chlorophycean genus Tetradesmus. The new species can be distinguished from similar Tetradesmus taxa due to its unique combination of features that are seen under light microscopy. We present herein a robust and comprehensive phylogenetic analysis of T. almeriensis, together with several additional Scenedesmaceae species, using a combination of maximum likelihood and Bayesian approaches. Our results confirm T. almeriensis as a distinct species consistently clustering with other Scenedesmaceae.

Taxonomic Importance

AbstractA new taxonomy of the Caloplaca citrina group in the Black Sea region is presented. It is based on the nrDNA ITS molecular data, chemistry (anthraquinone contents) and 20 morphological characters. Six species previously known in the region are accepted: Caloplaca arcis, C. calcitrapa, C. dichroa, C. flavocitrina, C. geleverjae, C. limonia. Five new species are described: Caloplaca arcisproxima, C. austrocitrina, C. communis, C. confusa and C. nigromarina. Seven further species, Caloplaca britannica, C. citrina, C. marina, C. maritima, C. microthallina, C. ora and C. phlogina are also treated briefly. Some maritime species known from the Atlantic coast of Europe are absent from the region, and, surprisingly, Caloplaca citrina s. str. could not be confirmed from the study area. A key to the species present in the region is provided, although morphological characters are of very limited value in this group. The variability and taxonomic importance of particular features are discussed. No significant differences in secondary chemistry were observed among the species.Many examples of convergence and some semi-cryptic species were revealed by molecular data. The term ‘semi-cryptic species’ is introduced here into lichenology for those species which cannot be clearly diagnosed by their morphology, but which are determined by other characters, mainly by their ecology and distribution. We propose to describe formally such species, in spite of difficulties with subsequent morphological identification.

A New Species

A new species belonging to Pluteus sect. Celluloderma with specimens collected in Artvin Province, Black Sea region, northeastern Turkey, is described as Pluteus anatolicus sp. nov. based on morphological characteristics and molecular data (nrITS). The new species was found in Fagus orientalis forests and is mainly characterized by a terrestrial habit, small-sized basidiomata, cracking pileus surface depressed at the center, broadly ellipsoid to ellipsoid basidiospores, narrowly utriform to narrowly fusiform or fusiform pleurocystidia with obtuse or subcapitate apex and sometimes with elongated pedicel, narrowly clavate to clavate cheilocystidia, absence of caulocystidia and pileipellis elements predominantly with a broadly mucronate apex and long pedicel. A comprehensive description and illustrations are provided, with its phylogenetic placement based on ITS also evaluated and including comparison to morphologically similar taxa and phylogenetically related species.

Lactarius subgenus Russularia is a dominant group of milkcaps in Southeast Asia. This paper reveals the large diversity   of the subgenus, with eight new species and one known species being described from montane evergreen and coniferous forests. All new species are supported by both morphological and molecular data, the latter using Maximum likelihood and Bayesian analysis based on the ITS region. Complete macro- and micro-morphological descriptions and illustrations are given. A key to the new taxa is provided. Lactarius chichuensis is reported for the first time from Thailand.

Corneriella indica sp. nov. is described from Kerala State, India. Comprehensive description, photographs, and comparisons with phenetically similar species are provided. Maximum likelihood analysis conducted on a concatenated dataset comprising ITS, nLSU, nSSU and rpb2 of the Tricholomataceae supported the generic placement and species validity of C. indica. Conspicuous cheilocystidia, one of the defining features of the genus, are missing in C. indica but the lamella edges are still sterile and composed of projecting tramal hyphae with cystidioid terminal elements.
