1994). The most conspicuous and aberrant process noted on the legs of an eriophyoid is the enlarged disclike projection of the dorsoparaxial surface of tarsus I in the genus Aberoptus, as discussed above (Fig. 21d). External anatomy and notation of structures 26 Ambulacra The terminal structure of legs I and II in larval and postlarval instars of all known Eriophyoidea is reduced to an empodium; other remnants of a pretarsus and paired claws are lacking. The empodium, aptly called the "featherclaw", is branched symmetrically into few to many rays, which in turn are usually secondarily branched and end in enlarged tips (Figs.

The genual seta, inserted dorsally or dorsolaterally, is generally the largest of the leg setae on leg I. Its homology is more problematical than the femoral seta. As the true dorsal seta, d, on the genu is not a fundamental larval seta among such out-group taxa as Tydeioidea (Andr6, 1981) and Tetranychoidea (Lindquist, 1985a), the genual seta of eriophyoids appears to represent the posterolateral seta, l", which commonly occupies a nearly dorsal position on leg I, though often a more dorsolateral position on leg II.
