fraternus Saussure, 1859a: 322 -323 [ Polydesmus (Fontaria) ].

Côte orientale du Mexique. Unspecified number of ♂ and ♀.

Saussure (1860) stated that he had four ♂ and three ♀, collected “dans les vallées du versant oriental de la Cordillère”. The MHNG has two ♂ and two ♀ in the dry collection under the name Fontaria fraternus . One ♂ and the two ♀ have the data label “Cordova, Mexique, M H de Saussure,” the other ♂ has “Pic Orizaba, Mexique, M H de Saussure.” There is also a glass vial containing a pair of gonopods secured by a pin through the cork stopper. All are part of the type series; the ♂ from Cordova was designated as the lectotype by Hoffman (1970: 155). There is a paralectotype in the ZMHB ( Moritz & Fischer, 1978; ZMB202).
