Maller in Mafra ( Santa Catarina), and abstracting from the coloration, agrees well with the original description of this species [  T. gahani]. Uniform black in color, only the neck and gula are yellowish-red and the anterior edge of the prosternum is rustyred. Although the difference in color is notable, I still think it is just a new variety...” Later, Zajciw (1964)described  Merionoeda( Merionoeda) latipennisbased on two specimensalso from Mafra and also collected by A. Maller. The holotypemale and the allotypefemale were destroyed during the fire in 2018 at the MNRJ. Júlio (1997)provided a new rank for  T. tristis, transferred it to  Oxycoleus, and considered  M.( M.) latipennisas its junior synonym. In the key to species of  Oxycoleus, Júlio (1997)separated  O. tristisfrom  O. gahanias follows (translated): “Pronotum black; elytra dark brown, opaque,” leading to  O. tristis; “Pronotum reddish-brown; elytra bluish, shiny,” leading to  O. gahani. However, Gounelle (1911)described the color of the female holotypeas follows (translated): “Black, thorax, anterior and middle coxae rufous, labrum testaceous.” He also described the elytra as opaque and with also opaque subtle pubescence. These two affirmations by Gounelle (1911), apparently, contradict the information about  T. gahaniin the key by Júlio (1997). Unfortunately, all specimens examined by Júlio (1997)belonged to the MNRJ and were destroyed during the fire in 2018. Thus, it is not possible to confirm whether or not they belonged to  T. gahani.   Material examined.  BRAZIL,  Minas Gerais: Pouso Alegre, 1 male[reported as being female in Martins & Galileo (2003)],  I.1960, Pereira& Medeirosleg.
