Trochanter notch. hairs of the abdomen are almost exclusively short and plumose. Abdominal hair pat- terns are often, but not always, reinforced by underlying pigment patterns (as the red abdominal spot in C. descripta, C. crocata, C. jloridana, and C. occidens). Tlie sternum is usually sparsely covered with long simple hairs or thicker setae (see section on abdominal setae below). The legs are usually covered with non- erect, simple hairs, and density is expressed as lightly, moderately, or heavily hirsute. Thorocic groove. The thoracic groove ("fovea" of British arachnologists) (Fig. la) is expressed as weak, moderately weak, moderate, moderately strong, or strong, de- pending on its length and depth. In some taxa it is entirely absent and is often re- placed with a poorly defined thoracic im- pression. Trochanter IV notch. On the distal, ven- tral margin of the trochanter (second seg- ment of the leg) there is often a small notch (Fig. 4). Tliis notch is usually rounded and is strong, moderate, weak, or absent. Sculpture. Sculptural characteristics are not found extensively in the Castianeira, but are used in Mazax, where great differ- ences in surface textures exist. Surfaces are described as granulose, rugose (full of wrinkles), or Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
