Macrelmis celsa

Passos, Maria Inês Silva Dos, Miranda, Gustavo Silva De & Nessimian, Jorge Luiz, 2015, Three new species of Macrelmis Motschulsky (Coleoptera: Elmidae: Elminae) from Southeastern Brazil with new definition of species groups to the genus, Zootaxa 4058 (2), pp. 195-210 : 204

celsa species group Sampaio et al. 2012

Diagnostic character: parameres smaller than aedeagus; aedeagus wide and with sub-truncated apex ( Figs. 3G – I ); hind tibia and pronotum ponctuate and granulate; pronotal sublateral carinae absent.

Species: Macrelmis celsa , M. codris and M. nessimiani .

Distribution ( Fig. 6 ): Brazil: Santa Catarina ( Hinton 1946) and Goiás ( Barbosa et al. 2013).

History of the group: This group was never formally proposed and was first used by Sampaio et al. (2012), probably referring to the group composed by Macrelmis celsa , M. codris and M. aequalis , species cited as closely related by Hinton (1946). It is possible that M. aequalis is part of this group (see Hinton 1946), but as this species does not have the male genitalia described and/or illustrated, we decided not to include it. M. nessimiani was not assigned to any group in its description and is proposed here as part of this set of species.

The question mark in frame B over São Paulo state represents M. salti, another species with not many detail, beside the state where it occurs in Brazil.
