Genus Neoperkinsiella Muir, 1926
Distribution: Tropical northern South America and southern Central America.
Type species: Neoperkinsiella williamsi Muir, 1926 (a junior synonym of Neoperkinsiella testacea (Fowler, 1905)).
There are two described species in this genus.
Neoperkinsiella guaduae Muir, 1926 - Ecuador
Neoperkinsiella testacea (Fowler, 1905) - Ecuador, Guatemala, Panama (Canal Zone)
Economic importance: Limited.
Muir (1926) reported Neoperkinsiella guaduae from Guadua sp. (Poaceae; Bambusoideae), a thorny bamboo, near Mera, Ecuador (Pastaza province).
An apparently uncommon genus, similar to Stobaera with the flattened antennae, but larger and with different genitalia (in Stobaera segment 10 has only a midventral process in caudal view and the shape of the parameres is quite different). Stobaera is rare from South America (Stobaera occurs throughout Central America). Kramer (1973) synonymized williamsi with guaduae.
I do have some specimens that appear to be Neoperkinsiella guaduae, although I have not confirmed this. Size and shape are similar to testacea, but the frons pattern is quite different.
Molecular resources: None.
