Recognized species
This genus is represented by a single species
Euidelloides montana Muir, 1926: 17 – Ecuador (Mt. Tungurahua [as Tunguragua], 10,000 feet)
Economic importance
Limited. This is a rare species known only from the 1 male and 5 females originally collected and described (to the best of my knowledge).
Plant associations
Collected from the bamboo Chusquea sp. (Poaceae)
Host from Muir, 1926; same reported in Wilson et al. (1994).
Recognition
I have seen one of the female paratypes (in the CASC collection, in San Francisco), but I am otherwise unfamiliar; I have requested specimens from BPBM on loan, and will photograph when available.
Description of genus from Muir 1926: 16-17
“Vertex broader than long, base broader than apex, a curved carina divides frons from vertex, but there are no carinae on vertex, base slightly sinuous; in dorsal view frons projecting slightly in front of vertex. Length of frons about twice the width, sides slightly arcuate, slightly broadest in middle, median carina simple. Antennae reaching to near middle of clypeus, second segment about 1.5 times the length of first, first longer than broad. Clypeus tricarinate, in profile slightly curved. Pronotum tricarinate, lateral carinae straight diverging posteriorly, not reaching hind margin. Mesonotum tricarinate. Hind basitarsus longer than other two together; spur not as long as basitarsus, thin, median size, teeth on hind margin.”
