‘Chlorita’ edithae White

Edith’s Green Leafhopper (‘Chlorita’ edithae)

Edith’s Green Leafhopper, which is or was endemic to the island of Saint Helena, was described in 1878, however, its genus name is placed between quotation marks because it apparently is invalid and the species belongs in another genus.

This species was found by Mrs. and Mr. Wollaston at Cason’s, Diana’s Peak, and high Peak in the central ridge of the island, but was not recorded during field surveys in 1965/66 and during the most recent searches in 2005/06 and is probably extinct now. [1]

Stonasla undulata White

Undulated Hopper (Stonasla undulata)

The Undulated Hopper is endemic to the island of Saint Helena; it was originally found in the remaining native vegetation at Casons, more or less in the center of the island.

The species was adapted to the endemic Dogwood tree (Nesohedyotis arborea (Roxb.) Bremek.).

It reaches a length of 0,8 to 0,9 cm and is yellowish green colored, its hemelytra bear some undulated darker stripes.

The species was not found during the latest field searches and might indeed be already extinct. [1]

Nyhimbricus wollastoni (White)

Wollaston’s Leafhopper (Nyhimbricus wollastoni)  

Wollaston’s Leafhopper, which is/was endemic to the island of Saint Helena in the southern Atlantic Ocean, was described in 1878.  

The species reaches a length of about 0,5 cm, it is distinctly pale yellow colored and bears orange marks on its head and its pronotum as well as orange bands on its forewings.  

The species was not found during intensive searches in recent years and is thus probably already extinct. [1]
