Three new species of Macrelmis Motschulsky (Coleoptera: Elmidae: Elminae) from Southeastern Brazil with new definition of species groups to the genus Author Passos, Maria Inês Silva Dos Author Miranda, Gustavo Silva De Author Nessimian, Jorge Luiz text Zootaxa 2015 4058 2 195 210 journal article 39260 10.11646/zootaxa.4058.2.3 aef58d69-0e0c-4ad8-8e27-3a00ea2bc448 1175-5326 241270 7BF705F4-BB24-4BC4-9430-A2AB8A990DDF 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.
