| Diagnosis | Diagnosis. Atractus hoogmoedi is distinguished from all species of Atractus by having an undivided sulcus spermaticus. Among congeners, Atractus hoogmoedi shares only with A. guerreroi, A. steyermarki, and A. zidoki a unlobed hemipenis. Atractus hoogmoedi differs from the first two by having apical pits and supra-anal tubercles in the male specimens (vs. absence of apical pits and supra-anal tubercles). The new species differs from A. zidoki by having 170–171 ventral scales in males and 180 in the single female and an undivided sulcus spermaticus (vs. 173–187 in males and 196–200 in females and bifurcated sulcus spermaticus). Along with A. zidoki, the new species shares apical pits and supra-anal tubercles exclusively with A. alphonsehogei, A. caxiuana, A. collaris, A. gaigeae, A. limitaneus, and possibly A. surucucu (Prudente and Passos, 2008). Atractus hoogmoedi differs from these species by having a single hemipenis and short loreal scale (vs. bilobed hemipenis and moderate to long loreal scale). Based on easily observed characters, Atractus hoogmoedi can be distinguished from A. alphonsehogei, A. collaris, A. gaigeae, and A. limitaneus by having the loreal scale in contact with second and third supralabials and five maxillary teeth (vs. first supralabial contacting loreal scale and six or seven maxillary teeth); from A. caxiuana by postnasal preventing internasal–loreal contact (vs. internasal contacting loreal); and from A. surucucu by a creamish white tail (vs. uniformly black tail).

| Comment | Atractus hoogmoedi, previously reported as a disjunct population of A. zidoki south of the Amazon River, differs from all congeners in having an undivided sulcus spermaticus. |
| Etymology | The specific epithet is a noun in the genitive case, honoring Dutch herpetologist Marinus Steven Hoogmoed. Marinus was curator of reptiles and amphibians at the National Museum of Natural History (Leiden, The Netherlands) for 38 years (1966–2004) before retiring as research associate at the Museu Paraense Emílio Goeldi in Belém, Brazil, where he is still very active. |
