strangulatus Humbert & Saussure, 1870: 175 [ Spirostreptus ].

Brasilia. Unspecified series.

Saussure & Humbert (1872) gave a more detailed redescription, indicated the type locality as Mato Grosso and stated that they had two ♀ specimens. The MHNG collection contains one ♂ specimen in alcohol under the name Spirostreptus strangulatus . The specimen is in a vial and there is a pair of gonopods in a second vial. A label in the jar reads “ Spirostreptus strangulatus Sss. et H., Brésil Mus. Vienne” indicating that it could be a syntype. Another label, dated 1960, states that Hoffman designated the specimen as lectotype, but this designation does not appear to have been published, possibly because the sex of the specimen makes its status as a syntype questionable. There is one broken ♀ syntype in the NHMW (Inventory number 2443, Acquisition number 1866.I.79). The Acquisition Register indicates that this lot comprised two specimens collected by Natterer, who was active in the Mato Grosso between 1823 and 1829. An undated label in the jar indicates that Hoffman considered the species to belong to the genus Pseudonannolene .
