Sternorrhyncha

Fossil of Pincombea sp., from Shcherbakov & Popov (2002).


Belongs within: Hemiptera.
Contains: Aleyrodidae, Psylloidea, Coccidomorpha, Aphidoidea.

The Sternorrhyncha are a group of small plant-sucking bugs including the aphids, scales, whiteflies and plantlice. They are commonly sedentary except when dispersing, moving little if at all. They are usually thought to be divided between two main lineages, of which the Psyllomorpha (including the whiteflies and plantlice) have jumping hind legs and eggs with short peduncles that may absorb water from the host plant (Grimaldi & Engel 2005).

The aphids (Aphidomorpha) and scale insects (Coccidomorpha) form a group with polymorphic individuals within a population, reduced or absent male genitalia, and winged morphs with a composite vein in the forewing comprised of R and the bases of M and Cu (Grimaldi & Engel 2005). The fossil record of the Aphidomorpha goes back to the Triassic; the Late Triassic Creaphis theodora is a stem-aphid differing from later forms in having forewings with a long stem to vein Cu, and long straight Rs and M veins (Grimaldi & Engel 2005). The Naibiidae are a group of superficially aphid-like bugs known from the mid-Triassic to the early Palaeocene. Though lacking evidence of sexual dimorphism, they share a number of features with scale insects such as a dorsoventrally flattened head and few, widely-spaced ommatidia, and are likely stem-group relatives of the Coccinea (Shcherbakov & Popov 2002).

Characters (from Grimaldi & Engel 2005): Head extremely opisthognathous, with labium originating from or close to prosternum; proboscis with fine, hairlike feeding stylets, coiled in head capsule when at rest. Antenna with eight or fewer flagellomeres. Hind wing lacking vannus and vannal fold. Tarsus one- or two-segmented.
