Abstract
In this contribution, supplementary descriptions of Cyphoderus innominatusMills, 1938 and C. limboxiphius nitricolaRapoport & Izarra, 1962 are provided; and three new species are described: C. adversussp. nov., C. amazonicussp. nov., and C. parafolsomisp. nov.; chaetotaxy for all of them is included. The new species have a labial triangular field with a1–5, m, e, l1smooth chaetae, and l2as reduced spine, but C. adversussp. nov.is characterized by a trochateral organ with at least 9 spine-like chaetae; tenent hair capitate; colophore chaeta Dmic, lateral flap chaetae with uneven length; dens with De1–De6/Di1–Di6feathered chaetae; mucro only with a, while C. amazonicussp. nov.is differentiated by a trochateral organ with at least 16 spine-like chaetae; tenent hair acuminate; colophore chaeta Dmac, lateral flap chaetae small and subequal; dens with De1–De6/Di1–Di5feathered chaetae; mucro with aA. Cyphoderus parafolsomisp. nov.has trochateral organ with more than 14 spine-like chaetae; unguis with 1 unpaired internal tooth; tenent hair capitate; dens with De1–De6/Di1–Di5feathered chaetae; mucro with aA. A key for identification of the Neotropical species is provided. Also, the paper describes the information about the association of Cyphoderuswith different ant species, and a new taxonomic status for C. nitricola(Rapoport & Izarra, 1962) comb. nov.
