crassicornis Humbert & Saussure, 1870: 177 [ Spirostreptus ].

Nova-Granada. Unspecified series.

Saussure & Humbert (1872) gave a more detailed redescription of the ♂ only, and stated that the specimen(s) had been collected by Natterer. No specimens found in the MHNG. There is one broken ♂ type specimen collected by Freidrichsthal in the NHMW (Inventory number 2167, Acquisition number 1866.I.51a). 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 placement of this species in the genus Spirostreptus in the original description 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).
