Tribe DIASPIDINI Targioni Tozzetti

Diagnosis: AF without fringed plates (except in some bamboo-feeding species), with gland spines; L2 bilobular; ducts 2-barred; long axes of orifices of marginal macroducts usually oblique or perpendicular to body margin; pores by anterior spiracle usually present, usually 3-locular; marginal macroducts usually the same size as, or only slightly larger than, dorsal macroducts. 2F similar to AF. CR without seta on tarsus. AM postoccipital ridge not produced posteriorly into a median process; anterior arms of postoccipital ridge separated by a distance equal to or greater than their own length; with 1 pair of tentorial pits. 2M usually with tricarinate scale cover and distinctly different from 2F, with more dorsal ducts and often having modified ducts unlike those seen in females.

This tribe is notable for the marked sexual dimorphism of the second-instar nymph. Male scale covers in the field often have 3 distinctive ridges or carinae, and on a microscope slide second-instar males often have distinctive ducts not seen in other life stages; these differ between the subtribes as described below.

Included genera: Furchadaspis MacGillivray , Gadaspis Borchsenius , Ischnaspis Douglas , Nimbaspis Balachowsky , Prodiaspis Young , Pygalataspis Ferris , Roureaspis Takagi , Trischnaspis Ben-Dov , and the genera listed in the subtribes below.
