Remarks

1) The small differences in coloration of Mycotretus nigrocinctus Lacordaire , M. trabeatus Lacordaire and M. tigratus Lacordaire are expected to occur in species of Mycotretus of a single locality and, in spite of that, we observed that these species have the same general colour pattern. Therefore, here we synonymized M. trabeatus Lacordaire under M. tigratus Lacordaire. 2) Crotch (1876) placed M. nigrocintus under M. tigratus stating only the following: “ M. nigrocinctus has lost the elytral spot, retaining only the band”. That act was interpreted by Kuhnt (1909) as a “variety” and was repeated in subsequent works ( Kuhnt 1911; Blackwelder 1945). Later, Mader (1951) stated the following: “tigratus a. nigrocintus Lac. ”, with the “a” probably meaning an “aberration” and this interpretation was followed by Alvarenga (1994). Here, we considered Crotch’s act as a synonymy and consider use of the term “aberration” as incorrect.
