Genus Mitrops Fennah, 1944
Type species (in original combination): Fulgora noctivida Linnaeus, 1767.
Mostly a Neotropical genus. Sparsely found in eastern U.S.
There are 3 recognized species. A key to species is found in Baptista et al. 2006.
[See Metcalf 1946: 59]
Mitrops dioxys (Walker, 1858) – Argentina, Paraguay, Panama, Costa Rica, Guatemala, Mexico (Chiapas, Nuevo Leon); USA: FL, KS, MD, MS, NJ, TX.
= Mitrops curviceps Stal, 1862; syn. by Distant, 1887: 40.
Mitrops guarani Baptista, Ferreira & Da-Silva, 2006 – Brazil

Known host plants:
Mitrops dioxys – Phaseolus vulgaris L. (kidney bean, Fabaceae)
Hosts from Donovall (2008); plant names from USDA PLANTS or Tropicos. See also FLOW.
North of Mexico, one of only 3 macropterous, ‘green’ (in life) genera. Tegula lacking carinae, head upcurved (both unlike Nersia); pronotum shallowly notched (deeply in Rhychomitra); wings with six or seven cells adjoining nodal line (not forming line in Rhychomitra); hind tibiae with 4 posterior spines.
Description of genus from Fennah 1944 (via Donoval 2008)
Vertex fully twice as long as broad across base, elongate-triangular, curved evenly upward distally, lateral margins converging to apex with a small but distinct notch before eyes, margins raised, horizontal in profile, disc flat, anteriorly concave, devoid of median carina distally, if not entirely, posterior margin transverse; frons elongate, margins feebly sinuate, only a little widened before clypeus, median carina present only at middle, lateral carinae strongly developed, meeting posteriorly in an acute point, converging in distal two thirds reaching near to clypeal suture; genae tumid before eyes, not riged. Pronotum in middle line one quarter length of vertex, anteriorly convex, median carina strong, an impression near its base on each side, lateral carinae not reaching hind margin, carinae behind eyes of equal thickness. Protibiae not exceptionally long, post-tibiae with four spines. Tegmina with R simple to nodal line, stigma with four cells. Wings with R four-branched, M four-branched at margin. Aedeagus with a pair of posterior spines on periandrium, a pair of straight spines at middle, and a pair distally on membranous sacs, penis ending in two long curved membranous limbs with a spine at apex of each. Ovipositor with first valvulae beset dorsally with a row of about ten teeth, a longer oblique tooth at apex, third valvulae elongate, six times as long as wide. Bursa copulatrix ornamented with sclerotised rings each bearing three sclerotised beadlets subequally spaced on ring.
Key to 2 species from Fennah 1944
1 Base of vertex smooth to depressed medially, lacking median carina; apex of cephalic process strongly curved upward; posterior spines of aedeagus three x as long as broad across base … Mitrops noctividus
1’- Median carina present in posterior portion of vertex; apex of cephalic
projection only curved upward; posterior spines of aedeagus only as
long as broad across base … Mitrops dioxys
Occasionally to lights or sweeping. Not common in the US.
As of this writing (1 Oct. 2018), there are appears to be no molecular data for this genus on Barcode of Life (there is a specimen record). Genbank includes data for Mitrops sp.
