[1] Myostola occidentalis is basically dark brown, with pale rose-coloured hairs on the joints of the palps and legs.
[3] In 1899, Reginald Innes Pocock transferred the species to the African genus Phoneyusa.
[1] In 1892, Eugène Simon gave a description of the genus Pelinobius, but in 1903 realized that the species he used for the description was actually very different from the type species of Pelinobius (P. muticus) and was probably identical to Lucas's Mygale occidentalis.
[4] Simon's decision to place M. occidentalis in a separate genus, rather than in Phoneyusa, was supported by Robert Raven in 1985.
[5] Myostola occidentalis is found in Gabon and Cameroon, in West Africa.
