Tube Spittlebug

Description:

I can't identify this Tube Spittlebug beyond the subfamily Machaerotinae at the present time. I almost stopped at the family Machaerotidae, but Wikipedia states the following: "There are about 115 species in 31 genera placed in 4 tribes. The majority of species are found in Southeast Asia with a small number for Africa. They were traditionally separated into two subfamilies Machaerotinae which have the scutellar spine and Enderleiniinae which lack it. A third family, also lacking the spine, Apomachaerotinae, was introduced in 2014. The scutellum has a "tail" or appears raised towards the posterior end."

Habitat:

This Tube Spittlebug was spotted in our front garden on a Pigeon Pea (Cajanus cajan). This plant has many regional names in the Philippines. In the area where I live, it is called "Kardis".
