In two previous articles, we reported that the male genitalia of six species of Parabrochymena and 14 species of Brochymena were distinct, particularly the shape and length of the vesica, thus supporting the establishment of Parabrochymena. Here, we present genitalic and nongenitalic information on four of the remaining five species of these two genera. Because of the results of these analyses, and in combination with similar analyses of species described earlier, we have transferred three of the four species [i.e., Parabrochymena enigmatica (Ruckes), Parabrochymena inbio Larivière, and Parabrochymena poeyi (Guérin-Méneville)] to Brochymena. Also, we have provided descriptions of Brochymena and Parabrochymena and the New World tribe (Halyini), which includes only these genera.
