GONATOCERUS Nees, 1834 View in CoL

( Figs 147–151 View FIGURES 147–149 View FIGURES 150, 151 )

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

Diagnosis. Gonatocerus is distinguished by the following combination: vertex with 2 setae between lateral ocelli ( Fig. 147b View FIGURES 147–149 ); mandibles of normal length, with 3 distinct, equal teeth and crossing when closed; pronotum divided medially by longitudinal suture and the lobes abutting medially ( Fig. 150 View FIGURES 150, 151 ) except sometimes slightly separated dorsally; fore wing relatively narrow, with apex evenly rounded, and with microtrichia usually as dense posterior to venation as distal to venation ( Fig. 149 View FIGURES 147–149 ); stigmal vein with apex usually slightly oblique; dorsellum diamond-shaped ( Fig. 150 View FIGURES 150, 151 ); propodeum with faint, converging sublateral lines, or lines absent ( Fig. 150 View FIGURES 150, 151 ); pronotal spiracle about same size as propodeal spiracle ( Fig. 150 View FIGURES 150, 151 ); ovipositor not produced anteriorly under mesosoma.

Remarks. Gonatocerus belongs to the Gonatocerus group of genera, treated formally as Gonatocerini by Huber (2015a). Gonatocerus appears to be most similar to Cosmocomoidea . Useful features that help distinguish Gonatocerus species are: fu 2 and fu 3 usually slightly the longest funicle segments and apex of fu 2 often oblique. The dorsellum margins are sometimes lighter in colour than the rest of the dorsellum. Otherwise, Gonatocerus is more difficult to characterize than the other genera in Gonatocerini .
