THE EPISTOMO-LABRAL PLATE AND LATERAL LIPS IN SOLIFUGES, PSEUDOSCORPIONS AND MITES

摘要: DUNLOP J.A.: The epistomo-labral plate and lateral lips in solifuges, pseudoscorpions mites. In GAJDOS P., PEKAR S. (eds): Proceedings of the 18th European Colloquium Arachnology, Stara Lesna, 1999. Ekologia (Bratislava), Vol. 19, Supplement 3/2000, p. 67-78. Solifugae Pseudoscorpiones are accepted by most recent authors as sister taxa, forming a clade Haplocnemata. group Haplocnemata is less certain. Most have Acari monophyletic placed them Ricinulei, although (Ricinulei + Trigonotarbida) relationship has also been proposed. an attempt to resolve some these phylogenetic questions, mouthparts Solifugae, were investigated. three orders mouth covered dorsally projecting (a fused epistome labrum), ventrolaterally pair finger-like lips, probably derived from coxae pedipalps. This character complex not seen other arachnids, similar, perhaps homologous structures occur Opiliones. interpreted here possible synapomorphy for (Acari (Solifugae Pseudoscorpiones)).
