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 : 206-207

jureceki new species group

Diagnostic character: presence of folded structure ventrally to the aedeagus; parameres shorter than aedeagus (see Jach (2002): figs. 2–4; Spangler & Santiago (1986): figs. 1, 2).

Species: Macrelmis jurececki and M. leonilae .

Distribution ( Fig. 7 ): USA: California ( Jäch 2002). Mexico: Oaxaca, Veracruz: Chiapas, Guerrero, Morelos ( Spangler & Santiago 1986). Guatemala: El Progreso ( Spangler & Santiago 1986). Honduras: Choluteca, El Paraíso and Francisco Morazan ( Spangler & Santiago 1986).

History of the group: Jäch (2002) considered M. jureceki similar to M. isus , both species differing in body size, pronotal and elytral width, elytral sculpture, size of prosternal process, and impressions on metasternum and first abdominal sternite; besides these differences, the male genitalia of these two species are completely different, dissimilar enough to separate them in different species groups, as proposed here. Brown wrote in an unpublished letter that M. jereceki resembles M. tarsalis “in dimensions and general appearance”, but their genitalia differ considerably (see grandis species group; Jäch 2002).
