In this contribution, supplementary descriptions of Cyphoderus innominatus Mills, 1938 and C. limboxiphius nitricola Rapoport & Izarra, 1962 are provided; and three new species are described: C. adversus sp. nov., C. amazonicus sp. nov., and C. parafolsomi sp. nov.; chaetotaxy for all of them is included. The new species have a labial triangular field with a1–5, m, e, l1 smooth chaetae, and l2 as reduced spine, but C. adversus sp. nov. is characterized by a trochateral organ with at least 9 spine-like chaetae; tenent hair capitate; colophore chaeta D mic, lateral flap chaetae with uneven length; dens with De1–De6/Di1–Di6 feathered chaetae; mucro only with a, while C. amazonicus sp. nov. is differentiated by a trochateral organ with at least 16 spine-like chaetae; tenent hair acuminate; colophore chaeta D mac, lateral flap chaetae small and subequal; dens with De1–De6/Di1–Di5 feathered chaetae; mucro with aA. Cyphoderus parafolsomi sp. 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–Di5 feathered chaetae; mucro with aA. A key for identification of the Neotropical species is provided. Also, the paper describes the information about the association of Cyphoderus with different ant species, and a new taxonomic status for C. nitricola (Rapoport & Izarra, 1962) comb. nov.

在这篇文章中，提供了Cyphoderus innominatus Mills, 1938 和C.limboxiphius nitricola, Rapoport & Izarra, 1962 的补充描述；并描述了三个新物种：C. adversus sp。十一月 ，C. amazonicus sp。十一月 和C. parafolsomi sp。十一月 ; 包括所有这些的毛毛排列。新种有一个唇侧三角形区域，有a1 – 5、m、e、l1光滑毛毛，l2为减少的刺，但C. adversus sp 。十一月_ 特征是转子器官具有至少 9 个棘状毛毛；租户头发头状；颜色毛毛D mic，侧瓣毛毛长度不均匀；有De1 – De6 / Di1 – Di6羽毛毛毛虫的巢穴；mucro 仅具有，而C. amazonicus sp。十一月 通过具有至少 16 个棘状毛毛的转子器官来区分；头发尖；颜色毛毛D mac，侧瓣毛毛小且近等长；有De1 – De6 / Di1 – Di5羽毛毛毛虫的巢穴；mucro 与aA。Cyphoderus parafolsomi sp. 十一月 具有转子器官，具有超过14个棘状毛毛；具有 1 个未配对内齿的爪；租户头发头状；有De1 – De6 / Di1 – Di5羽毛毛毛虫的巢穴；mucro 与aA。提供了识别新热带物种的关键。此外，本文还描述了Cyphoderus与不同蚂蚁物种的关联信息，以及C. nitricola的新分类地位（Rapoport & Izarra，1962）梳子。十一月
