This was found on poplar trees and in poplar logs in the Chino swamp.
Chelanops serratus n. sp. Fig. 3
Description: Length—Pedipalps, 3 mm. Impossible to take measurements of other parts, for slide was so poorly made, but the body was small. Color—Cephalothorax and pedipalps, strong yellow brown; legs and abdomen, light yellow.
Cephalothorax: As long as it is broad, sides evenly convex, upper margin straight, one distinct median suture; no eye spots; surface of cephalothorax very granular.
Figure 4. Ideoroncus obscurus Banks. Forward part of the animal from above. ×25.
Abdomen: Badly curled up; scuta entirely covered with short almost clavate hairs.
The naming of this species is based on the short "saw-like" hairs that are all over the body. They are not globular on the end, as the clavate hairs, but have "saw-like" edge.
