Current valid name
Oxyopes salticus Hentz (family Oxyopidae)
Recognition and diagnostic features
Six of its eyes in hexagon pattern on top of the cephalic region with remaining 2 smaller eyes anterior. Many leg spines perpendicular to leg. Body coloration should be sufficient for identification. Might be confused with Oxyopes scalaris, might be confused with jumping spiders because of compact body form and relatively short legs, might be confused with Mimetus hesperus due to large number of leg spines.
