LYMAENON Walker, 1846

( Figs 170–174 View FIGURES 170–172 View FIGURES 173, 174 )

Lymaenon Walker, 1846: 49 . Type species: Lymaenon acuminatus Walker, 1846 View in CoL , by subsequent designation by Gahan & Fagan, 1923: 82. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Lymaenon is distinguished from other members in Gonatocerini by the following combination: ocellar triangle with 3 or, rarely, 4 setae between lateral ocelli ( Fig. 170 View FIGURES 170–172 ); pronotal lobes separated by a usually membranous gap ( Fig. 172 View FIGURES 170–172 ); mesothoracic spiracle much larger than propodeal spiracle; dorsellum strap-like, with anterior and posterior margins parallel ( Fig. 172 View FIGURES 170–172 ); propodeum with parallel or slightly converging submedian lines ( Fig. 172 View FIGURES 170–172 ), often with spicules between them; stigmal vein with apex truncate ( Fig. 171 View FIGURES 170–172 ).

Discussion. Lymaenon belongs to the Gonatocerus group of genera, treated formally as Gonatocerini by Huber (2015). In the Afrotropical region the Gonatocerus group also includes Cosmocomopsis , Gonatocerus , Heptagonatocerus , Octomicromeris , Tanyxiphium and Zeyanus . Lymaenon is the most commonly collected genus of the group, with a greater diversity of species than any other region except Australia. A few species have the female antenna with funicle 7-segmented. Lymaenon is superficially most similar to Gonatocerus but the strap-like dorsellum immediately distinguishes it. Cosmocomopsis has an almost parallel-sided dorsellum but its long petiole distinguishes it.

Afrotropical hosts. Unknown.
