Description
|
|
Color. Gray.
|
Male. Vertex of the head with a pair of unequal, somewhat compressed,
almost vertical horns, posterior margin with four equally-spaced spines.
Pro- and mesonota multituberculate and granulate.
Abdominal tergites II-VI granulate, VII and VIII laterally expanded distally,
VII-IX tricarinate, X apically rounded-truncate.
Subgenital plate tuberculate, with a strong, pyramidal median tooth, apical
margin truncate.
Cerci slender.
Lower median carina of middle and posterior femora apically spinose, dorsal
posterior carina of those femora with two small lobes apically; both dorsal carinae
of the tibiae with a small basal lobe; posterior first tarsomere about as long
as the next three together.
Tegmina and wings absent.
Female. Surface of the head multituberculate, vertex with a pair
of unequal, almost vertical horns, posterior margin with four equally-spaced spines.
Pronotum subquadrate, surface multituberculate, posterolateral angles spinose, but
not dilated; mesonotum coffin-shaped, with a pair of irregular excrescences in the
apical third, lateral margins of the notum only slightly dilated.
Meso- and metapleurae tuberculate.
Abdominal tergites obscurely tricarinate, the median carina not produced into lobes,
segments broadened gradually to tergite VI, VII slightly narrower, V-VII with rounded
and elevated lateral expansions, posteriorly the expansions are irregularly dentate.
Subgenital plate convex, apically narrowed.
Dorsal carinae of the femora apically dilated into foliaceous lobes, anterior femora
a little shorter than the mesonotum; tibiae with only the dorsal carinae foliaceously
lobed; first hind tarsomere subequal in length to the next two.
Tegmina and wings absent.

Systematic notes. This species is distinguished by its small size, the
very large horns on the head, the lateral expansions on abdominal tergites V-VII of the
female, the relatively long first tarsomere, and teh absence of tegmina and wings in the male.

Derivation of name. Dryope, a woodpecker, is used as a noun in apposition
to the generic name. (Actually, I just like the sound of the name.)
