Differential diagnosis. The most obvious difference between E. basiatus   sp. nov. and all other species on Castelnaudia   is the retention of two claws on leg I of the male. This species is also distinctive within the basiatus   subgroup by having: tiny setae tc″ on tarsi II-III (minute-2 versus distinctly larger (3–5) in all other species, being at least twice as massive); and shorter idiosomal setae (e.g., females with short d (7–9) versus 12–23 in the other species).

Etymology. The specific name basiatus   (a kisser) refers to the distinctive lip-like protrusion of the gnathosoma   found in this species group.
