Rhachidomorpa adunca Saussure & Humbert 1872

uncinatus Humbert & Saussure, 1869a: 152 [Polydesmus (Rachidomorpha)].

Mexico, Cordillera orientalis. Unspecified number of ♂ and ♀.

Saussure & Humbert (1872) gave a more detailed redescription and the localities “Monte Azul, Cerro de Azeamela, Sierra de Agua, dans la Cordillère orientale.” They also noted that the species lived under the bark of pines. Carl (1903) illustrated the gonopod, although it is not clear which specimen(s) he studied. The MHNG collection contains one ♂ specimen in alcohol under the name Rhachidomorpha uncinata labelled as a type. The specimen is in fragments and lacks a data label. It was transferred from the dry collection and is presumably a syntype that had been placed in the collection before Saussure & Humbert (1872: 158) replaced the name with Polydesmus (Rachidomorpha) aduncus because it was a junior homonym of P. uncinatus Peters, 1864. There are also two broken specimens in alcohol under the name Rhachidomorpha adunca, also labelled as types.
