- Аннотация: Wing structure is one of the most important features for the bat morpho-ecological grouping. The goal of this work was to research morphological diversity of wings in the Rhinolophoidea superfamily. 50 species of 8 genera were included in analysis. According to wing shape Rhinolophoid species are divided into three groups: 1) broad-winged with large chiropatagium - Megadermatidae, Nycteridae, and part of Rhinolophidae; 2) broad-winged with small chiropatagium - most of Rhinolophidae; 3) narrow-winged with small chiropatagium - Hipposideridae. Analysis of wing structure diversity showed that variety of forms is determined by ratios of proximal and distal wing elements. The first trend of variability based on changes in proximal parts is evaluated in Hipposideridae. The second one involving variations in distal elements was observed in Rhinolophidae, Megadermatidae, and Nycteridae. Within different morpho-ecological groups of Rhinolophoidea parallel rows of wing structure variations were identified. On the other hand similar wing shapes caused by the development of different parts of the wing can be seen in Rhinolophidae and Hipposideridae families. Possibly the main hunting stratagies in Rhinolophoid bats, i.e. perchers and gleaners (Megadermatidae and Nycteridae), flattering aerial foragers of highly cluttered space ( most of Rhinolophus, some Hipposideros, Coelops), fast flying aerial foragers of open space (most of Hipposideridae, some Rhinolophus), are presented each by number of particular versions based on sets of morphological adaptations revealed herein.
