Recorded Distribution(s):
It is common on several islands in the Caribbean. It was collected from Puerto Rico, Antilles, Santo Domingo, Haiti, Cuba, and Jamaica by Martorell and Adsuar in (1952). It is not known to occur in the United States. (Neilson, 1968)

This species was first suspected as a vector of bunchy top virus of papaya in 1938, but it was not until 1946 that Adsuar (4) obtained evidence of successful transmission in experiments conducted in Puerto Rico. The symptoms of the disease were expressed on 71 of 90 healthy test trees in about 1½ months. In 1947, Séin and Adsuar (680) confirmed transmission by collecting leafhoppers from diseased trees and caging them on healthy ones. Males were separated from females and caged on 30 healthy plants, 9 of which developed the disease in 1½ months. Further evidence of transmission was obtained by Bird and Adsuar in 1952(72).


(Nielson 1968)

This species is the only known vector of bunchy top virus of papaya and, therefore, is considered an important vector of this virus.

Species Description

Length:
Small, fragile species. male 3.00—3.10 mm., female 3.25—3.50 mm.

Colour:
General color yellow. Crown, pronotum, and elytra yellow, immaculate.

Genitalia:
Pygofer in lateral aspect slightly longer than wide, ventral margin with long process arising from base and curved dorsally along caudal margin, apex bifurcate; aedeagus in lateral aspect with basal part very long, narrow, distal part broad, short, slightly curved; gonopore apical; style in dorsal aspect with apical two-thirds long, slender, attenuated apically; female seventh sternum in ventral aspect with caudal margin distinctly convex.

Species Diagnosis

This species is related to devastans and can be separated by the male pygofer with a forked ventral process.
