Abstract
The higher level cladistic structure of cribellate spiders (Araneomorphae) and ontogenetic evidence relevant to the homology of sclerites in the male spider palp arc reviewed, with the aim of clarifying orb-weaver phylogeny. The habitual use of a small set of terms for rather different palpal structures seems to have obscured homologies and therefore the monophyly of groups. Outgroup comparison of palp structure in various cribellate superfamilies (e.g., Dictynoidea and Amaurobioidea)can be used to polarize characters in orb-weaving spiders (Orbiculariae), and palp structure in Deinopoidea to polarize palp characters in Araneoidea. Results are that the radix of Linyphiidae and Araneidae may be synapomorphic, but the radix in such families as Oecobiidae, Uloboridae, and Theridiidae is in each case an autapomorphy of those taxa. The terminal apophysis in lycosoid taxa is entirely different from that in Araneoidea, and even within Araneoidea terminal apophyses in Theridiidae, Araneidae, and Tetragnathidae apparently are not homologous. On the other hand, possession of a median apophysis is probably primitive for Araneoidea. Problems surrounding the use of the terms median apophysis and conductor for various uloborid sclerites are discussed. A tentative cladogram of 32 orbicularian taxa, based on 87 binary and multistate characters, is presented.
