Taxonomic description

Ebook "Genome mapping and genomics in arthropods" provides comprehensive and up-to-date reviews on genomic research on a large variety of selected animal systems, contributed by leading scientists from around the world. Insects and other arthropods, the largest group of animals in number of species, have global impact on agriculture, industry, human health and environment. They are of particular economic importance for food production as pollinators, for natural products like silk and also as pests and parasites.

Vietnam is home to at least ten species of the genus Trimeresurus (Asian green pitvipers) and at minimum five members are found in Laos. The number has been increasing in recent years because of new species descriptions, e.g., Trimeresurus guoi, and new records of recently discovered taxa, such as T. cardamomensis.

Two species of Whalleya from Guizhou and Hainan Provinces were collected during the investigation of Xylariales from 2019 to 2021. According to morphological and molecular characteristics, Whalleya hainanensis sp. nov. and W. microplaca are introduced. Whalleya hainanensis differs from W. microplaca by its obovoid or tubular perithecia and the slightly raised stromata; and differs from W. maculata by its smaller ascospores. Their detailed morphological descriptions and illustrations are provided. The taxonomic position of Whalleya is discussed.

A new species of the Macrobiotus hufelandi group is described from Poland. An integrative taxonomic approach was applied by combining morphological and morphometric analysis imaging under phase contrast and scanning electron microscopy with molecular analysis (four molecular markers) to unambiguously support the establishment of the new species. The specimens of Macrobiotus hannae sp. nov. are similar to three taxa of the Macrobiotus hufelandi complex: Macrobiotus hufelandi C.A.S. Schultze, 1834; M. punctillus Pilato, Binda & Azzaro, 1990; and M. joannae Pilato & Binda, 1983.

Lucoppia nicora Djaparidze, 1986 was found in garlic fields in the Kastamonu region of Turkey. This finding is a new record for Turkey and also the first finding after its description from Nikortsminda cave and a vegetable garden in Tbilisi, Georgia. Redescription of the species is accompanied by a discussion of its taxonomic status. Based on differences having generic character in the structure of the prodorsum (length of lamellae; width of translamellae; distance between ro, le, and in setae), L. nicora is regarded as belonging to the subgenus Oribatula (Zygoribatula).

The aim of this study was to demonstrate and evaluate the diatom communities in the copper infected areas readily associated with the Hindustan Copper Limited (HCL) at the bank of the Subarnarekha River. This study was based on three sampling sites commonly designated as high copper (>100 μg.L-1 ), medium copper (≤100 μg.L-1 ) and low copper (≤50 μg.L-1 ) contaminated area. Results indicated the detailed taxonomic description of 31 species that are dominant or less dominant over these contaminated area. Among the identified taxa, 10 were recorded as new to the Jharkhand state.

The actual variation and specific diversity of Neotropical Draconanthes aberrans is evaluated based on morphological data. As recognized in this paper D. aberrans complex includes a total of 6 species, 3 of which are described here. New combinations are proposed for Lepanthes prionota and L. trachysepala. Two species, including D. aberrans, are lectotypified. The previous incorrect typifications are discussed. Each of 6 species is morphologically characterized.

We studied the application of the neglected name Centaurea leucolepis DC., concluding, by examination of the literature and original material, that the associated taxon is C. corensis Vals. et Filig., endemic to Campania region (southern Italy) and introduced into Sardinia. The name by Candolle is legitimate and it is here lectotypified by a specimen kept at G. In addition, after field surveys and herbarium searches, we suggest that this taxon should be considered as a subspecies of C. deusta Ten.

Composting is an important technique for environment-friendly degradation of organic material, and is a microbe-driven process. Previous metagenomic studies of composting have presented a general description of the taxonomic and functional diversity of its microbial populations, but they have lacked more specific information on the key organisms that are active during the process.
