Evolutionary Morphology and Phylogeny of Araghnida

Abstract: Abstract— This paper reports results from a cladistic analysis of the 11 Recent arachnid orders. The polarities of 64 newly discovered and traditional characters were determined through outgroup comparisons that included Eurypterida, Xiphosura, Trilobita and Crustacea. A branch‐and‐bound algorithm was used to discover a single tree (consistency index 0–59). The relationships suggested by this analysis differ substantially from previous interpretations of arachnid phylogeny, and a new taxonomic system is introd… Show more

“…The species of the order Opiliones are characterized by the presence of a pair of exocrine glands located at the anterior margins of the cephalothorax near the base of the second pair of legs (Shultz, 1990). These glands produce a variety of volatile secretions that are released under the threat of predation (Eisner et al, 1978).…”
