Abstract
A new distribution map is provided for Cryptostroma corticale (Ellis & Everh.) Gregory & Waller. Hosts: Sycamore (Acer pseudoplatanus), maple (A. campestris) and other Acer spp. Information is given on the geographical distribution in Europe, England, southern England to Norfolk and Somerset, France, Paris, Grenoble, German Federal Republic, Italy, North America, Canada, Ontario, USA, Michigan, Wisconsin, Great Lakes Region, WA.
The mating behaviors of Philodromus rufus-like spiders from the Pacific coast, northern Ontario, and southern Ontario near Belleville revealed two species and a subspecies. P. rufus Walckenaer is identified as a transcontinental species in which the males vibrate their legs in courtship and possess an "angular" retro-lateral apophysis on the palpal tibia. P. rufus vibrans Dondale is a small, heavily-speckled subspecies of rufus. The second species is P. exilis Banks, in which the males do not vibrate and have a "non-angular" apophysis, and which occurs in the Great Lakes-St. Lawrence-Acadian forests of eastern North America.
