The specific name remotus is derived from the Latin word for "remote", referring to the isolated type locality (Serpent Island).

[2] An interesting feature of Mascaraneus remotus is the lack of any stridulatory organ on the upper prolateral surfaces of the first two coxae of the legs.

As a near constant rule, large terrestrial theraphosids have a stridulatory organs of some shape or form.

Another theory is that it came from Eastern Africa, but this is unlikely, as then one would expect eumenophorine tarantulas distributed on the Seychelles, from which only ischnocoline theraphosids are known.

[2] It lives in rock crevices and is active at night, where it feeds upon other invertebrates, lizards and seabird chicks.
