The taxonomically important characters and subgeneric subdivision of Dichagyris are presented with several historical nomenclatural considerations. Subdivision D. vallesiaca is revised based on the type material known subspecies. psammochroa group revised, description a new species, kurbatskyi from Kazakhstan, one subspecies, kopetdaghimena Kopet-Dagh massif. taftana species (D. guentereberti A...

The paper deals with the computation of rank and identifiability a specific ternary form. Often, one knows some short Waring decomposition given form, problem is to determine whether minimal unique. We show how analysis Hilbert-Burch matrix set points representing can solve this in case forms. Moreover, when not unique, we procedure liaison provide alternative, maybe shorter, decompositions. gi...

The taxonomy of Micronectidae in Vietnam is reviewed. Based on our cumulative collections during 2001–2020, 11 new species Micronecta Kirkaldy, 1897 are documented and described this study: M. acuminata sp. nov., arcuata caperata clavata cultellata fulvopicta nieseri pingae sinuata undulata vietnamica nov. Nine recorded from for the first time: decorata Lundblad, 1933, drepani Nieser, 2000, ery...

Background This research explores the universality of genetic variation in genes controlling wood formation across the genus Eucalyptus. Breeding and deploying Eucalypts for improved wood quality is constrained by the delay before wood traits can be measured reliably. Marker assisted selection (MAS) offers a way to make earlier selection of wood properties, by selecting Single Nucleotide Polymo...

-Two of the elements of the tarsus are illustrated in plate 1, figures 3 to 4b. The astragalus and calcaneum resemble the corresponding bones in Leptoreodon graciiW Scott. Concluding RPmarks.-Hesperomeryx edwardsi is more closely related to Leptoreodon than to Leptotragulus. It differs from Leptoreodon marshi and from L. gracilis in certain features of the dentition regarded as of subgeneric ra...

The aphid genus Aspidophorodon Verma, 1967 is reviewed, with descriptions of three new species from China, namely Aspidophorodon (Aspidophorodon) cornuatus Qiao sp. nov., Aspidophorodon (Aspidophorodon) musaicus Qiao sp. nov., and Aspidophorodon (Aspidophorodon) obtusus Qiao sp. nov.. Aspidophorodon sinisalicis Zhang, 1980 and Trichosiphonaphis lijiangensis Zhang, Zhong & Zhang, 1992 are consid...

Rhizopogon (Basidiomycota, Boletales) is a genus of hypogeous fungi that form ectomycorrhizal associations mostly with members of the Pinaceae. This genus comprises an estimated 100(+) species, with the greatest diversity found in coniferous forests of the Pacific northwestern United States. Maximum parsimony analyses of 54 nuclear ribosomal DNA internal transcribed spacer (ITS) sequences inclu...
