Acutangulus coccineus ( Humbert & Saussure, 1869 )

John Hollier, Edmund Schiller & Nesrine Akkari, 2017, An annotated list of the Diplopoda described by Aloïs Humbert alone and with Henri de Saussure, and the Diplopoda from Saussure’s Mexico expedition, Revue suisse de Zoologie 124 (2), pp. 203-224 : 208

coccineus Humbert & Saussure, 1869a: 152 [ Polydesmus (Tropisoma) ].

Cordillera orientalis mexicana . Unspecified number of ♂ and ♀.

Saussure & Humbert (1872) gave a more detailed redescription, the locality “Orizaba” and the information that they had 22 individuals collected by Sumichrast. Carl (1903) illustrated the gonopod on the basis of an “Originalexemplar.” The MHNG collection contains one ♂ and two ♀ in alcohol, under the name Strongylosoma coccinea , that are labelled as types. The specimens have been transferred from the dry collection and although they do not have data labels they are clearly syntypes. The NHMW contains two ♀ syntypes (one incomplete) donated by Humbert & Saussure (Inventory number 3421, Acquisition number 1866.I.E).
