Melanoplus propinquus Scudder, 1897 - Southern Red-legged Melanoplus



Male
Taxonomy
Family: Acrididae Subfamily: Melanoplinae Tribe: MelanopliniSynonym: Melanoplus femurrubrum propinquus
Comments: Melanoplus is our largest genus of Orthopterans, with over 350 species occurring in North America (Cigliano et al., 2017). 38 species have been recorded in North Carolina. Along with M. sanguinipes and femurrubrum, M. propinquus belongs to the Sanguinipes Species Group (Cigliano et al., 2017).
Species Status: Propinquus has been considered by some authors (e.g., Blatchely, 1920; Helfer, 1987) to be a subspecies of femurrubrum. It is listed as a separate species by the Orthoptera Species File, however, which is how we treat it here.
Identification
Field Guide Descriptions: Online Photographs: BugGuide, Google Images                                                                                  
Comments: Grayish-brown with a red hind-tibia; the underside of hind femur is also shaded with red. Similar in overall appearance to M. sanguinipes and femurrubrum, although duller and less yellowish than the latter. The diagnostic features are structural, however, and any photographs submitted as this species must show the external reproductive structures of the males.
Structural Features: The furculae of the male reach at least half-way across the supra-anal plate, with the fingers extending fairly straight (Scudder, 1897); those of femurrubrum often reach less than half-way across and are more tapering, widely separated, or divergent. The cerci are also more rounded at the apex than in femurrubrum, which are more angulated, appearing diagonally truncate from above (Scudder, 1897; Capineira et al., 2004). See Structural Photos.
