Male

Arizona and New Mexico as well as adjacent Mexico. (1)

H. dossenus and H. clypeatus are very similar and both occur in southern Arizona. In the eastern part of their overlapping range, they are fairly distinct, but in the western part, they may be difficult to tell apart, especially if you are judging by their 3rd legs. Some other characteristics to compare:

* The underside of the 1st legs of H. dossenus are typically bare and greenish and fringed by thin white hairs, while the underside of the 1st legs of H. clypeatus are typically covered with scattered white scales and are more grayish in color.

* H. clypeatus typically has a white or tan band above the primary eyes, while H. dossenus doesn't.

The two species have also been known to hybridize.
