Eupromerella Fisher, 1938 Eupromerella inaequalis (Galileo & Martins, 2011),

comb. nov.

Psapharochrus inaequalis Galileo & Martins, 2011: 177; Wappes & Arias, 2016: 8 (holotype); Monné, 2019: 296 (cat.).

Galileo & Martins (2011) described Psapharochrus inaequalis based on a single male from Bolivia.According to Martins & Santos-Silva (2013): “The main feature that allows the separation of Eupromerella from Psapharochrus is the shorter body when the proportion between the head and prothorax is compared with the elytra. No other reliable character can be used to distinguish these genera.The main problem is that there are currently several different forms placed in Psapharochrus . However, this does not prevent the transfer of species from Psapharochrus to Eupromerella and does not classify it as a doubtful genus.”

Psapharochrus inaequalis is nearly identical to Eupromerella orbifera (Aurivillius, 1908) .The latter species was originally described in Psapharochrus and transferred to Eupromerella Fisher,1938 by Monné & Giesbert (1994). In reality, E. orbifera is a problematic species that could be included in either Psapharochrus (now Aegomorphus) or Eupromerella . Also, it is probable that P. inaequalis may only be a variation of E.orbifera, a species that also occurs in Bolivia. For now, it will be kept as a different species because the apex of the protibiae is entirely dark (only apex in the holotype and specimens examined), and its elytral pubescence slightly sparser (but with same pattern). It will be necessary to examine the holotype before a synonymy could be considered.

Known geographical distribution (Monné, 2019; Tavakilian & Chevillotte, 2019): Bolivia (Santa Cruz).
