Abstract
AbstractNothacrobeles borregi n. sp. is described from blow-sand in the vicinity ofthe roots of creosote bush (Larrea tridentata) from Anza Borrego State Park,San Diego, California. The new species is distinctive from all others of thegenus by the specific morphology of the labial probolae and lips, as viewedwith both interference light and scanning electron microscopy. The probolaeinclude a basal ridge unique by its large size, smooth rim (lacking tines),and unusual large triangular platelet projections on each side; the probolaeare also distinctive in having a knob-like ledge separate and posterior tothe basal ridge. Nothacrobeles borregi n. sp. provides a new insight intohomology of characters important for addressing problems with generic levelclassification in Cephalobinae. These hypotheses of homology suggest a basisfor transferring N. laticollaris n. comb. (syn. Cervidellus laticollaris).Characteristics of Nothacrobeles in relation to Cervidellus and Stegelletinaare discussed.
