Anaceratagallia venosa (Fourcroy 1785)
Description & Identification
Small, robust species. male 2.75—3.00 mm., female 3.10—3.35 mm. (Nielson, 1968)General colour light to dark brown; color deeply infuscated in males. Vertex with two large distinct black spots; pronotum with two large black spots near anterior margin, dark infuscated markings below spots in males; forewings with veins dark brown.(Nielson, 1968)Pygofer in lateral aspect about 1% times longer than wide, caudal margin produced posteriorly to distinct, elongated curved spine; spine attenuated and curved dorsally at apical third; 10th segment with pair of long spines directed posteroventrad along inside of caudal submargin of pygofer, apex triangulate; aedeagus in lateral aspect simple, compressed laterally in ventral aspect, basal two-thirds very broad, curved laterally, numerous short spines along ventrolateral surface; gonopore subterminal; style in dorsal aspect bibbed at apex, inner lobe long, about 2% times longer than outer lobe, curved laterally; female 7th sternum in ventral aspect with caudal margin slightly concave. (Nielson, 1968)This species is the only known vector in the genus Anaceratagallia. and it can be distinguished by characters of the male genitalia. (Nielson 1968)
Biology & Ecology
Little is known on the biology of this species. According to Sukhov and Vovk in 1947 (778), the main host was chicory, although it was observed on numerous other plants and is therefore a polyphagous feeder. (Nielson, 1968)

Vector Status
Economic Crops
This species is a vector of tomato leaf crinkle virus in Russia. It was first reported as a vector of this virus by Sukhov and Vovk (778) in 1947. The virus was transmitted by a population of 200 adults that were collected from weeds and potatoes and caged on 10 tomato plants. Four plants developed typical symptoms of the disease about 26 days after exposure to naturally infective leafhoppers. To my knowledge these results have not been confirmed.(Nielson 1968)This species is considered an important vector of this virus in Russia. Further investigations should be made to determine the relationship of this virus to those transmitted in South America by other species of Agalliinae.(Nielson 1968)
