status

 

clypeata  species group Hinton 1946

Diagnostic character: parameres and aedeagus of equal size, both short; parameres completely surrounds the aedeagus ( Figs. 5 E, FView FIGURE 5 A – F).

Species: Macrelmis clypeata  and M. isus  .

Distribution ( Fig. 6View FIGURE 6): Trinidad: Maracas ( Hinton 1936). Argentina: Cordoba, Jujuy, Misiones, Salta, San Luis, San Juan ( Manzo & Archangelsky 2001). Brasil: Goiás ( Barbosa et al. 2013), Rio de Janeiro ( Sampaio et al. 2012), Santa Catarina ( Hinton 1946). Bolivia: Sidras and Tarijá ( Manzo & Archangelsky 2008). Paraguay: Guairá ( Shepard & Aguilar Julio 2010).

History of the group: Macrelmis clypeata  was considered as closely related to M. tarsalis  by Hinton (1936). Afterwords, Hinton (1946) added M. isus  to this set of species and formaly presented this group. He defined it as “having the apices of the elytra dehiscent, each elytron being separately rounded at extreme apex, and by the unusual secondary sexual characters of the male” ( Hinton 1946). Despite of this resemblances, the male genitalia of M. tarsalis  differs considerably from that of M. isus  and M. clypeata  . So, only the last two species are considered to compose the clypeata  group.
