Not located.

Remarks

Junior synonym of Mycomystes coccineus ( Lacordaire, 1842) ( Fig. 27C , see below), see Pecci-Maddalena et al. (2021b). Part of Fauvel’s collection is now in the Royal Belgian Institute of Natural Sciences, RBINS ( Horn et al. 1990a) and the specimen shown in Fig. 14D belongs to that collection. Although it is a “topotype”, we believe that this specimen is not that used by Fauvel on his description. According to Fauvel (1860: 326): “(…) Palpes, épistome et base des antennes tescés (…)” and after: “L’exemplaire unique que j’ai sous les yeux perdu ses antennes moins deux articles de chaque côté”. We did not examine the individual shown in the plate ( Fig. 14D , image sent by the RBINS curator); however, it is possible to note that its right antennal club is present and, therefore, that specimen may not be Fauvel’s type.
