1. Subgenus Cyphomannia   HNS   Weber -

This optional category was founded upon the lone Bolivian species laevigatus Weber   HNS   . It is indeed a striking species. The completely smooth thorax, devoid of the costumary tubercles, teeth and spines is unique. Nevertheless, the overall appearance and a set of characters which to my mind are useful for infrageneric grouping (without going into subgenera) show that laevigatus   HNS   falls nicely into the rimosus-group, in a stricter sense, i. e. excluding the somewhat aberrant forms such as longiscapus   HNS   , costatus   HNS   , wheeleri   HNS   and possible allies. The head of laevigatus   HNS   is practically identical with that of bicornis   HNS   , and the latter also lacks a pronotal and epinotal armature, only the mesonotum having an anterior pair of conical low spines and a posterior pair of inconspicuous welts; in addition, the petiole and postpetiole of bicornis   HNS   are practically smooth as in laevigatus   HNS   (cf. Kempf, 1966: 177-9, figs. 4, 5, 23, 26, 32, 33). Moreover, Weber is wrong in assuming that when I first proposed this case of synonymy (Kempf, 1962) I had no direct knowledge of laevigatus-material. Already in 1961 (p. 518) I mentioned the specimens from Dutch Guiana which are perfectly identical with the types, available to me already by the end of 1962. Since Cyphomyrmex   HNS   contains other striking and morphologically isolated species (v. gr. occultus   HNS   , morschi   HNS   , longiscapus   HNS   ), there would be no end for decorative subgenera. Therefore, I consider Cyphomannia   HNS   a useless burden which should stay buried for the sake of healthy taxonomy.
