Melanoliarus eximus
Melanoliarus eximus is a species of planthopper in the family Cixiidae, a group of small, often inconspicuous insects associated with plant roots. The species was described by Caldwell in 1947. Like other cixiids, it likely possesses membranous wings held roof-like over the body and a piercing-sucking mouthpart adapted for feeding on plant vascular fluids. Members of this genus are generally found in North America.
Melanoliarus forcipatus
Melanoliarus forcipatus is a species of planthopper in the family Cixiidae, first described by Caldwell in 1947. Species in this genus are small to medium-sized fulgoroid insects characterized by their brachypterous (short-winged) condition in females and macropterous (long-winged) condition in males. Cixiidae planthoppers are generally associated with woody or herbaceous host plants, with nymphs often feeding on roots. The specific epithet "forcipatus" refers to a forceps-like structure, likely describing a morphological feature of the male genitalia or other appendage.
Melanoliarus zyxus
Melanoliarus zyxus is a species of planthopper in the family Cixiidae, first described by Caldwell in 1947. The species was originally described under the genus Sonorium and later transferred to Melanoliarus. As a member of the Cixiidae, it belongs to a diverse family of fulgoroid planthoppers characterized by their distinctive wing venation and association with vascular plants. The taxonomic status of this species has been subject to revision, with some sources treating it as a synonym while others recognize it as accepted.
