2. Macrostolops Grouvelle, 1916: 236 —Neotropical Region ( Paraguay).

The type species of this genus remains without re-examination. The describer mentioned that this genus could be placed between Brachypeplus and Macrostola with the body 3.0 × as long as wide and glabrous (except for abdomen), rather short head bearing exposed labrum, and also short and convergent antennal grooves, pronotum subexplanate at sides, with rounded anterior and posterior angles, elongate striate elytra and nearly conical abdomen with longest ultimate segment. The detailed original description of both genus and two species ( Macrostolops inusitatus Grouvelle, 1916 and M. singularis Grouvelle, 1916 ) seems to make it possible to recognize these species in additional new specimens when they are available. The type species should be deposited in the Museo de la Plata (Facultad de Ciencias Naturales y Museo, Buenos Aires) and Muséum national d’Histoire naturelle (Paris), however, at least in the latter collection no specimen of these species has been found.
