Abstract

At present, 45 Somoleptus species are known from the Neotropical region. Among these, 28 species are newly described here, whereas 18 were described in the past. The new species are: S. admirabilis spec. nov., S. andersoni spec. nov., S. ashei spec. nov., S. beniensis spec. nov., S. brevipennis spec. nov., S. breviusculus spec. nov., S. brooksi spec. nov., S. brunneus spec. nov., S. curtipennis spec. nov., S. curtulus spec. nov., S. elongatulus spec. nov., S. gigas spec. nov., S. grandiconus spec. nov., S. humicola spec. nov., S. longiceps spec. nov., S. loretensis spec. nov., S. maximus spec. nov., S. melanarius spec. nov., S. mexicanus spec. nov., S. montanus spec. nov., S. oculatus spec. nov., S. ovatus spec. nov., S. pecki spec. nov., S. peruanus spec. nov., S. recurvatus spec. nov., S. struyvei spec. nov., S. triangulus spec. nov., S. tschirnhausi spec. nov. Four species are transferred from the genus Lithocharodes. These are S. cavicola (Blackwelder, 1943) comb. nov., S. strigulata (Blackwelder 1943) comb. nov., S. longicollis (LeConte, 1863) comb. nov., and S. subtilis (Erichson, 1839) comb. nov. Somoleptus dichiformis Bernhauer, 1910 could not be assigned to either Lithocharodes or Somoleptus. Thus, this species must be treated as species incertae sedis. Two species groups could be differentiated due to the structure of the parameres and the aedeagal cones; one mainly occurs in South America, the second in Central America.
