In my opinion the literature records of C. lespesii HNS and C. lespesii melancholicus HNS from Paraguay pertain to a single species, and the differences in identification stem from alternate taxonomic interpretations on the part of Forel and Emery. All of the material I have examined is rather homogenous and closely matches Emery’s melancholicus HNS types. The distinct appearance of this ant renders it unlikely to be confused with any other species in Paraguay. Camponotus lespesii HNS is large (mesosomal length> 3.5mm in major workers) and more gracile than any other Paraguayan Camponotus HNS of similar size. Additional diagnostic characters include: head of major worker considerably longer than broad; sides of head of major bearing>15 standing setae; antennal scapes lacking standing setae; antennal scapes longer than head length; mesosoma low and elongate, declivitous propodeal face less than 1/3 length of dorsal face; sculpture of head, mesosoma, and gaster opaque.
Forel’s lespesii HNS type, a large minor worker from Colombia, is somewhat lighter in color than the Paraguayan specimens but is otherwise similar. For the purpose of eliminating a trinomen I synonymize C. melancholicus HNS here.
