摘要

This paper provides the first numerical cladistic analysis of erigoninephylogenetic relationships based on a sample of taxa. A total of 73 characters, most of them morphological, have been scored for 31 erigonine genera plus 12 outgroup taxa. The parsimony analysis of these data supports the monophyly of Erigoninae based on two synapomorphies: the male pedipalpal tribial apophysis and the loss of the female pedipalpal claw. The monophyly of linyphiidae and of Linyphiidae plus Pimoidae also is supported. One of the largest clades within the erigonines is the 'Distal Erigonines clade,' whose monophyly is supported by the loss of the taenidia in thetracheoles and the loss of distal dorsal spine of tribia IV. The clade composed of Stemonyphantinae plus Mynogleninae is the sister group of Erigoninae. A number of relatively 'basal' erigonine lineages, which have been classically regarded as 'taxonomically problematic' or 'transitional,' retain some plesiomorhpic characters typical of other subfamilies, like the haplotracheate system or the taenidia in the tracheoles. The available data suggest that the cephalothoracic sulci and glands found in mynoglenines and eriogonines are not homologous.
