Lace Bugs.
Salient features of adults. Terrestrial.
Phytophagous (on a variety of plants, with two very common species on thistles; some producing galls). Tiny, or small; 2–5 mm long; fliers; relatively stout bodied. Rostrum clearly separated ventrally from the prosternum by a sclerotized gula. Antennae longer than the head, readily visible from above; 4 segmented; non-aristate. Ocelli absent. Thorax conspicuously crested, or not crested. Fore-wings well developed; in the resting insect lying more or less flat over the abdomen; more or less uniform in texture (though the corium is more or less detectable); with a clavus; with conspicuously raised, reticulate venation; finely reticulate or areolate throughout. Hind coxae mobile; rotatory. Claws all apical. Pulvilli present. The abdomen without ventral silvery pubescence.
Fore-wings more or less uniform in texture, glassy, with a fine reticulum of raised veins; pronotum similarly patterned; the scutellum and clavus concealed by a triangular extension from the posterior lobe of the pronutum.

Illustrations. • Dictyonota tricornis (Original generic description. Hairy-horned Tingis: B. Ent. 154). • Dictyonota tricornis (detail: B. Ent. 154). • Dictyonota tricornis (dissections: B. Ent. 154). • Dictyonota tricornis (legend+text: B. Ent. 154). Dictyonota Curtis, of which this is the original description, is retained as a genus; but D. crassicornis Curtis is a synonym of D. tricornis. • Dictyonota tricornis (text: B.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
