status

new species

amazonica  new species group

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

Distribution ( Fig. 6View 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.
