Name

Pertydeus schusteri, first original combination
Tydeus (Pertydeus) schusteri, second original combination and subsequent designation used by Baker (1970: 165) and by André (2025: 163)
Lorryia schusteri, subsequent new combination used by Kaźmierski (1998: 336)
Brachytydeus schusteri, subsequent combination used by Silva et al. (2016: 24)
Brachytydeus (Pertydeus) schusteri, subsequent combination used by André (2025: 418, )

The description by André & Naudo is a bit confusing. Indeed, the description of the new species and the type species of Pertydeus designate Pertydeus schusteri (and NOT Tydeus (Pertydeus) schusteri). But two lines before and in the title, it is stated that Pertydeus is a subgenus of Tydeus. This classification is followed by Baker (1970: 165).
Re-established in its pristine state and re-assigned to the genus Tydeus by André (2025: 156).
Assigned to Brachytydeus (Pertydeus) by André (2026: 425)
