Miriochrus Galileo & Martins, 2012 

Miriochrus Galileo & Martins, 2012: 66  ; Monné, 2019: 256 (cat.).

Miriochrus  was described to include M. minimus Galileo & Martins, 2012  from Paraguay (see photograph of the holotype at Bezark, 2019). In the original description, the genus was compared to Nesozineus Linsley & Chemsak, 1996  (translated):“ Miriochrus  gen. nov. by the pronotum lacking tubercles, and by the small dimensions, resembles Nesozineus Linsley & Chemsak, 1966  , but differs by the eye lobes nearly divided (one ommatidium in the narrowest area between the lobes), scape piriform, short elytra with 1.5 times the humeral width, and presence of white seta inside of the elytral punctures. In Nesozineus  , the eye lobes are separated between them by three or four rows of ommatidia, the scape is subcylindrical, the elytra are longer, with more than 1.5 times humeral width, and the elytral punctures have no white seta.” Actually, Miriochrus  is much more similar to Eupromerella Fisher, 1938  , and primarily differs by the presence of white seta inside its elytral punctures, which are absent in Eupromerella  . This feature is also shared with the Plistonax Thomson, 1864  , and Melzerus Monné, 2005  .The species of Plistonax  are slenderer, and the apex of the prothoracic tubercles is blunt (acute in Miriochrus  ); Melzerus  has a distinct cavity in the ventral surface of the femora of males, which are absent in males of Miriochrus  , and the apex of the prothoracic tubercles is rounded.
