Untersuchungen zur Morphologie, Taxonomie und Phylogenie der Chelicerata1 II. Cladogramme und die Entfaltung der Chelicerata

Abstract: Zusamrnenfassung Im letzten Jahrzehnt sind eine Reihe von Klassifikationen der Chelicerata veröffentlicht worden, die nicht auf Synapomorphien gründen. Das Ziel der vorliegenden Untersuchung ist ein cladistisches System und eine plausible Vorstellung von der Entfaltung der Chelicerata. Zum Grundbauplan der Chelicerata gehört ein ungeteiltes Prosoma mit sechs extremitätentragenden Segmenten sowie ein Opisthosoma aus 12 Segmenten und dem Tergaldorn eines reduzierten 13. Segmentes. Es gibt keinen Hinweis darauf, … Show more

“…These Palaeozoic predatory chelicerates lived between 460 and 255 Myr ago and were probably the aquatic sister group of scorpions (Dunlop & Braddy 2001) or possibly all arachnids (Weygoldt & Paulus 1979). Megarachne, previously interpreted as the largest extinct spider, also belongs to this group (Selden et al 2005).…”

“…The relationship between scorpions and Eurypterida, the extinct group referred to as 'sea scorpions', has been a matter of historical debate [5][6][7][8][9][10]. The placement of scorpions within Arachnida was also considered controversial [9][10][11][12][13], but recent phylogenomic studies have favoured the Arachnopulmonata hypothesis: the sister group relationship of scorpions and tetrapulmonates (i.e. spiders and allied orders) [14,15].…”

“…Eles, no entanto, não testaram a monofilia dos ácaros, desde que empregaram a abordagem de codificar os estados considerados por eles como ancestrais da "ordem", ao invés de levar em conta os polimorfismos encontrados dentro do grupo. Weygoldt & Paulus (1979). B- Shultz (1990).…”

“…Esse táxon foi formalmente chamado Acaromorpha, apesar desse nome ter sido cunhado originalmente por Dubinin (1957), referindo-se apenas às linhagens de ácaros. Shultz (1990) realizou suas análises depois de uma pesquisa extensa da morfologia apendicular de todas as ordens de aracnídeos, mas repetiu a codificação por táxons supra-especificos, da mesma forma que Weygoldt & Paulus (1979). Assim, novamente, o monofiletismo de Acari não foi posto a prova.…”
