''O. ichneumon'' was considered a ''Polyrhachis'' ant mimic Ant mimicry or myrmecomorphy is mimicry of ants by other organisms.

Jerzy Prószyński
Jerzy Prószyński (born 1935 in Warsaw) is a Polish arachnologist specializing in systematics of jumping spiders (family Salticidae). He is a graduate of the University of Warsaw, a long-term employee of the Siedlce University of Natural Sciences and Humanities and the Institute of Zoology of the Polish Academy of Sciences in Warsaw. Biography In 1957 he completed his biological studies at the University of Warsaw. During his studies he was employed at the Institute of Zoology of the Polish Academy of Sciences in Warsaw, where he conducted research on spiders in the Kampinos Forest. Between 1963 and 1967 he lectured on zoology at the University of Ghana. In 1966 he obtained his Ph.D. at the Adam Mickiewicz University in Poznań. A year later he was given the opportunity to pursue a postdoctoral fellowship at Harvard University, but he was refused a passport. In 1972 he was employed at the Higher School of Education in Siedlce (later the Siedlce University of Natural Scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salticidae Genera
Jumping spiders are a group of spiders that constitute the family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider families because of the shape of the cephalothorax and their eye patt ...

Ant Mimicry
Ant mimicry or myrmecomorphy is mimicry of ants by other organisms. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive. Spiders are the most common ant mimics. Additionally, some arthropods mimic ants to escape predation ( protective mimicry), while others mimic ants anatomically and behaviourally to hunt ants in aggressive mimicry. Ant mimicry has existed almost as long as ants themselves; the earliest ant mimics in the fossil record appear in the mid Cretaceous alongside the earliest ants. Indeed one of the earliest, '' Burmomyrma'', was initially classified as an ant. In Wasmannian mimicry, mimic and model live commensally together; in the case of ants, the model is an inquiline in the ants' nest. Wasmannian mimics may also be Batesian or aggressive mimics. To simulate ants' powerful defences, mimics may imitate ants che ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyrhachis
''Polyrhachis'' is a genus of formicine ants found in the Old World with over 600 species. The genus is yet to be comprehensively resolved and contains many varied species including nest-weavers (e.g. ''Polyrhachis dives''), swimming workers (e.g. '' Polyrhachis sokolova''), soil (e.g. ''Polyrhachis proxima'') and tree-dwellers (e.g. ''Polyrhachis bicolor''). General morphology Size: Workers range in size approx 5-10mm in length. Eyes developed, no ocelli. Antennae have 12-segments. Antennal insertions situated far from posterior margin of clypeus. Mesosoma of most species have spines on one or more of its pronotal, mesonotal or propodeal components. Petiole armed with spines or teeth. First gastral tergite well developed, longer in dorsal view than exposed parts of the following terga together. Opening at gastral apex for release of venom lacking a radial fringe of hairs. Ecology ''Polyrhachis'' species include an array of nesting types ranging from terrestrial, soil based ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
