Arenivaga is a genus of sand cockroaches, of the subfamily Corydiinae, in the family Corydiidae. These cockroaches live in sandy soils and dunes in the southwestern United States, Florida and Mexico. Arenivaga comes from the Latin arena meaning sand and vagus meaning wandering.
This genus is sexually dimorphic, with males and females differing in morphology. The insects are dorso-ventrally flattened and males have wings that are generally longer than the abdomen. The colour cannot be relied on to distinguish between species because the insects sequester pigments from their food and therefore their colour depends on their diet; they accumulate uric acid in varying amounts, and this also affects their appearance.
The head has a pair of long, slender antennae, two large compound eyes and two protuberant ocelli. The labrum is broad, and the frons and the hinder part of the clypeus are fused and form a bulge in a manner unusual for cockroaches. The pronotum is large and covers the head and extends sideways to about the width of the body. There are setae on the dorsal surface of the pronotum and different species have different patterning, which may be impressed into the surface. The patterning may be surrounded by an aura which radiates out from the pattern, and at the side of the pronotum, uric acid may be stored in white or pale pink patches.
