Long-winged Planthopper; Derbid Planthopper

ok Frazier, noted with thanks :)

Here's my similar spotting http://www.projectnoah.org/spottings/717...

It has two common names. The species name was suggested as Proutista sp. (= one of the species of the genus Proutista but not sure which one.) So if you agree you can use the scientific name as Proutista sp. The common name is less important. You can use one or two (separated by a comma) :-)

actually I am still confused as the specific name. because when looking from both of the keywords with the same picture emerges.

Also known as a derbid planthopper (Derbidae)
