Size
Adult body length ranges from 4-8 millimeters in both sexes.(1)
Identification
Abdomen varies from reddish to black and can have a variable pattern of white spots. See diagrams in Gertsch, 1960(1), page 34, for examples. Sometimes the white spots can be extensive enough to cover most of the abdomen in white. Legs and carapace bright orange to dark brown.

When present, the frontal white abdominal spot is whole and never paired as in Asagena medialis. (The frontal white spot is not to be confused with the white "basal band" which is the crescent of white on the front of the abdomen.)

In females from Mono County, California, the abdomen may only have a median stripe and be missing all other lateral spots.(1) See example:
Range
Published records are from California and Oregon (1); and the SCAN Database adds Arizona, New Mexico, and Utah (2).
