GONATOCERUS Nees, 1834 View in CoL View at ENA

( Figs 452–466 View FIGURE 452 View FIGURES 453–457 View FIGURES 458, 459 View FIGURES 460–462 View FIGURES 463–465 View FIGURE 466 )

Gonatocerus Nees, 1834: 192 . Type species: Gonatocerus longicornis Nees, 1834 , by monotypy.

Diagnosis. Body length 640–1665 μm. Funicle with fu 2 and fu 3 usually the longest segment and often fu 2 with apex slightly oblique ( Fig. 457 View FIGURES 453–457 ); fore wing relatively narrow and as setose behind venation as beyond venation, with the microtrichia fairly dense ( Figs 452 View FIGURE 452 , 464 View FIGURES 463–465 ); stigmal vein with apex oblique ( Fig. 464 View FIGURES 463–465 ); dorsellum rhomboidal ( Fig. 458 View FIGURES 458, 459 ), often with margins slightly lighter in colour laterally than medially; propodeum without submedian carinae ( Fig. 458 View FIGURES 458, 459 ), but sometimes with faint converging sulci.

Discussion. Among the four genera in the Gonatocerus group ( Cosmocomoidea , Gastrogonatocerus, Gonatocerus , and Lymaenon ) that share the following combination of features: tarsi 5-segmented, funicle 8-segmented, face with subantennal sulci, and parastigma with hypochaeta about midway between proximal and distal macrochaetae ( Huber 2015a), Gonatocerus is superficially most similar to Lymaenon , but the pronotal lobes abut medially and the dorsellum is triangular as in Cosmocomoidea and Gastrogonatocerus but in contrast to Lymaenon .

Nearctic hosts. Hemiptera : Cicadellidae .
