Distribution. Caja de Muertos Island and mainland Puerto Rico (Caldwell & Martorell, 1951); Dominican Republic.

Remarks. A specimen collected from the Dominican Republic determined as M. arida by Kramer was studied, extending the known range of the species. This specimen differs from Caldwell’s illustration (Caldwell & Martorell 1951, plate 3) in the width of the endosoma, which is almost spine-like in the Dominican Republic specimen (but broad in the original illustration).
