Melanoplus keeleri luridus (Dodge, 1876) - Broad-necked Locust


No image for this species.
Taxonomy
Family: Acrididae Subfamily: Melanoplinae Tribe: Melanoplini
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.
Species Status: The two subspecies, M. keeleri keeleri and M. k. luridus, have long been recognized, based on differences in size, reproductive structures, and coloration; in North Carolina, moreover, they appear to be allopatric: Rehn and Hebard (1916) describe the nominate subspecies as being primarily Southeastern and found in the extreme southern end of the Appalachians only at elevations around or below 2,000'. Subspecies luridus, on the other hand, is primarily Northern and Western; it reaches North Carolina along the Appalachians and is found at higher elevations than the nominate form, often above 4,000'.

Comments: According to Blatchely (1920) subspecies luridus is characterized by features of the male and female reproductive structures as well as by the smaller size of the females: "subgenital plate as broad as long; upper fork of cerci bent distinctly upward; lower valves of ovipositor relatively short, distinctly decurved; females rarely over 25 mm. in length". See illustrations and more detailed descriptions given in Blatchely.
