Macrelmis grandis
status

new species

grandis  new species group

Diagnostic character: parameres with a longitudinal constriction in lateral view; distal half of parameres and aedeagus strongly curved ventrally; aedeagus slightly longer than parameres (see Hinton (1936): figs. 8, 9; Hinton (1940), figs. 118, 119).

Species: Macrelmis grandis  and M. tarsalis  .

Distribution ( Fig. 7View FIGURE 7): Mexico: Temascaltepec ( Hinton 1934). Costa Rica: Río Reventazon ( Hinton 1936).

History of the group: M. grandis  was suggested as close to M. granigera  by Hinton (1934) and to M. striata  , M. striatoides  and M. sandersoni  by Hinton (1940), but its genitalia is completely different from the latter four species. M. tarsalis  was not assigned to any group and was not compared to any other species in its description ( Hinton, 1936), but Hinton (1946) assigned M. isus  as being similar to a group formed by M. tarsalis  and M. clypeata  (the last species now in its own group).
