Melacoryphus lateralis (syn. Neacoryphus lateralis ) is a bug from the family of ground bugs (Lygaeidae). The bug is also known as the Charcoal Seed Bug ("charcoal seed bug ").
features
The bugs become 7-10 mm long. They are dark gray to black in color. The pronotum has an orange band on the front edge. On the back edge there is an orange spot on the side corners and in the middle. The outer edge of the corium is colored orange.
The species can be distinguished from other members of the genus Melacoryphus by the following features: fully winged (macropter), membrane of the wing hemispheres dark brown to black (not white) at the basal margin, but usually somewhat in the middle with an indistinct white spot. The corium has a red mark on the outside, but its rear edge is always brown to black. The side edges of the abdomen are of the same color as the rest of the abdomen, dark, not set off in red. The label (scutellum) is a single dark color, its tip not colored red.
distribution
Melacoryphus lateralis occurs in the Nearctic . Its range is in the western United States , particularly in the desert areas of Arizona, Nevada and California. It is also found in Mexico. Individual records are also available from Canada (British Columbia, Saskatchewan, Ontario).
Way of life
The bugs feed on seeds of various herbaceous plants . In the summer months of July and August, there can be a massive occurrence of bedbugs.
Taxonomy
The species was first described by William Sweetland Dallas in 1852 as Lygaeus lateralis and later transferred to the genus Melanocoryphus . For their New World representatives, a new genus Neacoryphus was set up by Samuel Hubbard Scudder in 1965 . In 1988 Alex Slater separated the species group around this species into a new genus Melacoryphus , Melacoryphus lateralis is the type species of this genus. This division is not recognized by all taxonomists, so that some continue to regard the name Neacoryphus lateralis as the valid name of the species. The genus Melacoryphus also includes ten other species in North and Central America.
