Identification
Octodentatus can be difficult to distinguish from sayi, especially in the males. Separating characters include: 1- The distance from the lateral ocelli to the vertex margin is larger than the distance between the lateral ocelli 2- The legs tend to be orange in color all the way from the tarsi up through the femurs, but they may be darker in some specimens 3- The vertex tends to be reddish brown, but may also be black Of these characters, the vertex/ocelli measurement character is the most dependable. Be sure to measure this character carefully. Eye-balling it is likely to be misleading. Discover Life
