Body black clothed with very dense yellowish pubescence with the exception of 2 areas near antennal scapes, 2 triangular areas on vertex, beginning from apical half of the 3rd up to the end following antennal segments, 2 longitudinal bands
on medio-lateral parts of pronotum and interspaces of elytral bands clothed with dark brown ground pubescence.
The colour patterning is observable around the entire circumference of the shell and is characterized by about twenty longitudinal bands subparallel to the shell axis.
pellucidum (Barrande, 1868) from the latest Ludlow of Bohemia in which the longitudinal bands are variable in width (Barrande 1868, pl.
The genus has a strong association with grasses and displays several co-evolved, adaptive characteristics such as a very elongate abdomen, a flat carapace, and light- to dark-brown longitudinal bands
along the carapace and abdomen, all of which aid crypsis in grasses.
Camptocosa texana has narrower longitudinal bands
on the carapace (Fig.

Now notice the three longitudinal bands
(taenia) running along the cecum.
Central figure bordered laterally by dark brown longitudinal bands
with irregular margins.
Cupiennius salei sometimes shows red setae on the chelicerae too, as can be observed in color drawings (Cambridge 1900) and even in living spiders, however, they don't fully cover the front of the chelicerae, so the characteristic dark longitudinal bands
of this species prevail.
