Candiani who contributed greatly to the knowledge of Neotropical Castianeirinae during his time at the Museu Goeldi. Diagnosis. Both males and females of Myrmecotypus candianii spec. nov. resemble those of M. ednae spec. nov. by the elongate thoracic region (twice the length of cephalic region), coxa I light brown and coxa II white, but differ by the absence of an RTA and the embolus short and folded (compare Figs 18G, H and 19G, H). Females differ by the epigynal transverse ridge procurved, with a small marginal sclerotized area (compare Fig. 18I and 19I). Description. Male (holotype). Total length 6.08.
