An annotated list of the Diplopoda described by Aloïs Humbert alone and with Henri de Saussure, and the Diplopoda from Saussure’s Mexico expedition Author John Hollier Author Edmund Schiller Author Nesrine Akkari text Revue suisse de Zoologie 2017 2017-09-30 124 2 203 224 journal article 31808 10.5281/zenodo.893503 c0dc4be8-6e76-47ef-989d-ee77833bfc09 893503 acutus Humbert & Saussure, 1870 : 176 [ Spirostreptus ]. Brasilia. Unspecified series. Saussure & Humbert (1872) gave a more detailed redescription of the ♂ only, and the type locality as “Nouvelle-Grenade”. No specimens found in the MHNG. The NHMW contains a ♂ type specimen broken into three parts with the locality “New Grenada”, donated by E. Friedrichsthal (Inventory number 2165, Acquisition number 1866.I.51). The Acquisition Register shows that this specimen was part of a lot of two individuals that were described as two species by Humbert & Saussure, and it is therefore the holotype. The “New Grenada” on the data label probably refers to San Juan de Nicaragua, where Friedrichsthal disembarked in 1839 (Fischer- Westhauser, 2007 ; Stagl, 2003 ). Hoffman (1999: 36) suggested that the original placement of this species in the genus Spirostreptus was a lapsus calami and that it was considered by the authors to belong to the genus Spirobolus . This generic placement was formalised by Bollman (1893: 60) . Spirobolus acutus ( Humbert & Saussure, 1870 )
