Etymology. This species is named after Dr Graeme Gillespie.

Remarks. The venter of M. gillespiei is similar to M. orientalis Wiles, 1999 but the pedipalp PIV differs considerably. The flattened shape of the larger ventral projection and the angular shape of the ventral margin of PIV are diagnostic of the species.
