amazonica View in CoL new species group

Diagnostic character: parameres significantly shorter than aedeagus; aedeagus with rounded apex ( Figs. 3A, C View FIGURE 3 A – I ). Species: Macrelmis amazonica , M. terea , M. thorpei , and M. tityra .

Distribution ( Fig. 6 View FIGURE 6 ): Brazil: Rondônia ( Hinton 1945) and Amazonas ( Hinton 1946). French Guiana: Saint- Laurent-du-Maroni ( Hinton 1946).

History of the group: Macrelmis amazonica was described as part of the graniger species group ( Hinton 1945), but the male genitalia of these four species share undeniable similarities, with the abovementioned characters. Macrelmis terea , M. thropei and M. tityra were considered as part of the aristae group by Hinton (1946) based on presence of pronotal sublateral carinae, but this character is also present in other species outside the group that do not have same male genitalia characters.
