Following the first records of Chthonius (Ephippiochthonius) boldorii Beier, 1934 in central Europe, a species which was previously assumed to occur exclusively in Mediterranean caves, 116 series (595 specimens) of the cryptic taxa C. (E.) boldorii and C. (E.) fuscimanus Simon, 1900 (Syn. C. (E.) austriacus Beier, 1931) were re-examined. Although multivariate analyses suggest specific separation, there is only one unequivocal character for discrimination: the presence or absence of a single isolated tooth on the moveable finger of the chelicerae. The distributions were found to be largely allopatric, therefore it is concluded that the species rank of the two morphospecies is justified. North of the Alps, an almost vicariant pattern emerged: east of 14° E fuscimanus occurs, west of this line boldorii occurs. The results provide a basis for discussing the relevance of minute morphological differences in pseudoscorpion taxonomy. 相似文献

Despite the great biodiversity in the Arachnida, some taxa are still now poorly known, mainly in terms of biology, ecology, and behavior. Pseudoscorpions are small arachnids (2–8 mm) that live in cryptic environments, being in general solitary predators of other invertebrates. The most studied Pseudoscorpion species are those from temperate areas, which revealed that Pseudoscorpiones present some level of sociality based on maternal care. Most developed sociality is seen in tropical species. Here, we reviewed this issue, presented examples of social behavior, and suggested the steps involved in the evolution of permanent sociality in the Neotropical Atemnidae genus, Paratemnoides. We discussed that the extended parental care, division of labor, cooperative breeding and feeding, and the tolerance among members dividing the same share could be considered enough to characterize a true social life, same in invertebrates. 相似文献

The mating behavior of the cave pseudoscorpion Maxchernes iporangae Mahnert & Andrade, 1998 (Chernetidae), was studied under laboratory conditions. A total of 24 pairings was observed. Mating was divided into three phases: predeposition (dance), spermatophore deposition and transfer, and posttransfer phase. The mean mating duration was 67.3 min based on 10 observations. Spermatophore morphology is described and consists of a stalk, a drop of fluid, and an -shaped sperm package. Males and females can mate several times in the same reproductive period. However, consecutive mating was not observed between a female and the same or another male. 相似文献

《Arthropod Structure & Development》2017,46(1):116-129
The cuticle of arthropods is usually composed of layers of a chitin-protein-microcomposite, a proteinaceous epicuticle and a thin lipid coating. However, in some instances a thick cement layer (cerotegument) covers the cuticle and may produce elaborate microstructures. This has previously been described for millipedes and mites. Here we report the previously unknown presence of a superhydrophobic cerotegument in whip-spiders (Ambypygi) and reveal its variation in ultrastructure and water-repellence between species. We discuss the relevance of found micro-morphological and physical characters for taxonomy and phylogenetics of this group, and the potential biological functions. 相似文献

The sperm of pseudoscorpions consists of a coiled head (nuclear material), axial filament and an annular mitochondrion, all enclosed within a cyst.
Variations occur in the gross morphology of different pseudoscorpion sperm. These variations are discussed in terms of possible morphological relationships. 相似文献

Two new species of the genus Stenohya Beier, 1967 are described from China: Stenohya pengaesp. n. (male and female; type locality Daming Mountain, Nanning City, Guangxi Zhuang Autonomous Region) and Stenohya huangisp. n. (female; type locality Gushan Mountain, Fuzhou City, Fujian Prov.).The presence of Stenohya pengaesp. n. in the tree crown of Castanopsis fabri represents a new habitat for Neobisiidae. A key and a distribution map of the Chinese Stenohya species are also provided. 相似文献

Summary The hair regeneration of a chemotactile sensillum was studied in the sunspiderGluvia during moulting. The sensilla in the old cuticle remain connected to the epidermis by dendrites which extend outwards during apolysis. The trichogen cells forming the new hairshaft in the exuvial space grow along the chemoreceptive dendrites, while the mechanoreceptive dendrites run separately. Morphogenetic aspects are discussed in comparison to results from other arthropods. 相似文献
