A comparative morphology of trichobothrial bases in araneoid spiders and its significance for the phylogeny and system of the superfamily Araneoidea (Arachnida, Araneae).

Bothrial morphology was studied by SEM in 137 araneoid genera representing all 22 currently recognized extant families and all 42 conventional subfamilies of the Araneoidea. The ancestral type in the superfamily Araneoidea is a 'hooded' bothrium with a single well-developed transverse ridge, dividing its proximal and distal plates ('-type'); the advanced type is a solid dome-like bothrium without vestiges of the ridge ('-type'); there are several intermediate types reflecting various pathways and stages of the ridge reduction (united here as '-type'). The parallel trends in bothrial evolution, recognized as continuous series from the ancestral type up to the advanced one through some intermediate stages, are distinguished in each of the seven main phylogenetic lineages of the superfamily: 'tetragnathoids', 'araneoids', 'cyatholipoids', and 'theridioids' possess a complete set of the three types, while 'malkariods', 'symphytognathoids'.

Resurrection of and taxonomy of the high-alpine species from the complex (Poaceae, Pooideae).

is a high-alpine species that occurs in cryophilous steppes, semi-deserts and stony slopes, from the Tian Shan and Pamirian Plateau through Qinghai-Xizang Plateau to the Himalayas and is characterised by a great morphological variability. During the revision of specimens of the taxon, we observed that the pattern of this variability is linked to the geographical distribution of the specimens. Numerical analyses (PCA and UPGMA) revealed three groups of OTUs corresponding to three morphotypes within the complex.
