Olios ID
Unfortunately the taxonomy of this family is just awful and Fox (1937) provides a lot of measurments but only a few drawings. That said, the RTA and cheliceral color do match O. fasciculatus but that doesn't eliminate O. giganteus which was synomimized within fasciculatus for many years. The distributional overlap between these two species is still unknown. Additionally there are supposed to be numerous undescribed species, so for now, the best we can do is Olios sp.
