Syn. nov.

Audinet-Serville (1835) included some species in his new genus Acanthoderes which indicated it was masculine gender ( Acanthoderes varius (Fabricius, 1787) , and Acanthoderes griseus (Fabricius,1792)) .However,it is actually feminine gender, as previously correctly indicated by Gemminger (1873) and Blackwelder (1946). Gemminger (1873) corrected the gender in only part of the species neglecting to do so for Acanthoderes melanosticticus .

Lacordaire (1872) transferred A. melanosticticus to Psapharochrus Thomson, 1864 . As Aurivillius (1923) considered Psapharochrus a subgenus of Acanthoderes , A. melanosticticus was mentioned in this subgenus until recently by nearly all authors, even after Psapharochrus had been considered a distinct genus. In Acanthoderes melanostictica the size of the ommatidia is very small ( Figs. 37-38 ) and the elytra have distinct carina ( Santos-Silva & Nascimento, 2018), hence it belongs to Scythropopsis Thomson, 1864 . It also has the protibiae distinctly widened toward apex ( Fig. 39 ), as in the type species of the genus.

Thomson (1865) described two species, in different genera, with the same name: Psapharochrus contaminatus ( Fig. 40 ), and Pteridotelus contaminatus ( Fig. 36 ). Monné & Giesbert (1992) synonymized Psapharochrus contaminatus with Acanthoderes melanostictus [sic]: “ Acanthoderes melanostictus White, 1855: 361 / Acanmoderes [sic] contaminatus Thomson, 1865: 543 , new synonymy.” However, Psapharochrus contaminatus is not equal to Scythropopsis melanostictica ( Fig. 35 ), rather it is Pteridotelus contaminatus that is the true synonym of the latter.
