Dichotomius (Luederwaldtinia) problematicus (Luederwaldt, 1924)

Pinotus problematicus Luederwaldt 1924: 7 (French Guiana?, Ecuador, Peru)

Distribution. French Guiana: Luederwaldt 1924: 7 (as Pinotus problematicus) (?). “Guianas”: Blackwelder 1944: 207 (as Pinotus inachus var. problematicus). Other: Luederwaldt 1924: 7 (Ecuador, Peru - as Pinotus problematicus); Blackwelder 1944: 207 (Ecuador, Peru - as Pinotus inachus var. problematicus); Medina et al. 2001: 138 (Colombia).

Note. The lack of recent records of Dichotomius problematicus from the Guianas supports Luederwaldt’s assumption that the type from French Guiana may be mislabeled. The occurrence of this species in the research area remains to be confirmed.
