Neotropical Acanthoderini (Coleoptera, Cerambycidae, Lamiinae): Synonymies and new status in some genera, new species, transferences and new distributional records

Abstract

Taxonomic notes are provided in some Acanthoderini genera. Three new species are described: Scythropopsis intricata Santos-Silva, Botero and Wappes from Mexico, Aegomorphus robustus Santos-Silva, Botero and Wappes and Eupromerella boliviana Santos-Silva, Botero and Wappes from Bolivia. The following synonymies are proposed: Psapharochrus Thomson, 1864 as synonym of Aegomorphus Haldeman, 1847; Acanthoderes (Psapharochrus) albomaculatus Fuchs, 1963 and Acanthoderes griseomaculata Zajciw, 1971 as synonyms of Symperasmus alboniger (Bates, 1861); Pteridotelus contaminatus Thomson, 1865 as synonym of Scythropopsis melanostictica (White, 1855); Psapharochrus jameswappesi Tavakilian, 2018 as synonym of Aegomorphus wappesi (Galileo, Martins & Santos-Silva, 2015); and Psapharochrus histrio Casey, 1913 and Psapharochrus guatemalensis Casey, 1913 as synonyms of Aegomorphus circumflexus (Jacquelin du Val, 1857). Acanthoderus circumflexus Jacquelin DuVal, 1857 is proposed as nomen protectum and Acanthocinus rusticus Klug, 1829 as nomen oblitum. Aegomorphus contaminatus (Thomson, 1965) is revalidated. Scythropopsis Thomson, 1864 and Symperasmus Thomson, 1864 are herein elevated to genus rank. The geographical distribution of ten species is expanded and a key to differentiate Acanthoderes, Aegomorphus, Scythropopsis, and Symperasmus is provided.

Two new species and taxonomical and geographical notes on Aegomorphus Haldeman (Coleoptera, Cerambycidae, Lamiinae)

“…Psapharochrus doctus; Monné, 2005: 203 (cat.). Aegomorphus doctus; Santos-Silva et al, 2020: 35. Bates (1880b described Acanthoderes doctus based on a single female from Mexico (Oaxaca) as follows (translated): "Elongate, convex, dark gray, elytra black punctate, with grayish band before middle, M-shaped black band after middle, and A-shaped black band near apex; antennae and legs dark reddish, ringed with dark flesh-colored bands, those bands linear in the apical segments; frons wide, flat, expanded toward anterior region; vertex with two black macula; thorax with large tubercles laterally and dorsally (their apices very acute); sides of prothorax coarsely punctate until coxae; elytral apex short, transversely sinuous-truncate; elytra with obtuse carina, arched and elevated basally, punctures sparse, with black setae, basally tuberculate; mesoventral process bituberculate; legs with long setae.…”

“…Psapharochrus umbratus; Maes et al, 2010: 375 (distr.). Aegomorphus umbratus; Santos-Silva et al, 2020: 36. Bates (1885 described Acanthoderes purulensis as follows (translated): "Similar to Acanthoderes lugens [currently, Scythropopsis lugens (Thomson, 1865)].…”
