mystecus Humbert & Saussure, 1869a: 150 [ Polydesmus (Fontaria)].

Mexico temperata. Unspecified number of ♂ and ♀.

Saussure & Humbert (1872) gave a more detailed redescription and gave the locality “Cordillère orientale, région moyenne”. The MHNG collection contains two specimens in alcohol under the name Fontaria mystecus . There is no data label but the identification labels in the jar have “Mexique” written on them. One of these labels reads “ Polydesmus mystecus Sss et H., Type, Mexique”, indicating that the specimens are syntypes.
