The Neotropical species of Dissomphalus with median tergal processes are defined as having a pair of median processes situated in a depression. These species are divided into 13 species groups: apeiius and altivolans, basidentatus, bifoveatus, bisulcus, cwvifoveatus, linearis, longiclypeus, rasissimus, stellatus, ulceratus, unitus, vallensis. Eight previously described Dissomphalus species: D. vallensis Evans, D. bisulcus Ashmead, D. bifoveatus Kiejfer, D. ulceratus Evans, D. apertus Kieffer, D. altivolans Evans, D. megomphalus Evans and D. deformis Evans are considered as having median tergal processes. The following 40 new species are described and illustrated: D. bicarinatus, D. largidentatus, D. tortuosus, D. stellatus, D. scavatus, D. rotundus, D. cerutus, D. basidentatus, D. planus, D. bisserratus, D. extrarramis, D. polidentatus, D. bifurcatus, D. triangularis, D. dilatatus, D. strictus, D. digitatus, D. curvifoveatus, D. horizontalis, D. angulatus, D. microculus, D. rasissimus, D. bilobatus, D. linearis, D. completus, D. incompletus, D. gigantus, D. serratus, D. multicoriaceus, D. scamatus, D. longiclypeus, D. concavatus, D. rectilineus, D. dentiformis, D. unitus, D. delgatus, D. subpilosus, D. parvus, D. subdeformis and D. lanceolatus.
