ZEYANUS Huber, 2015

( Figs 267– 271 )

Zeyanus Huber, 2015: 62 . Type species: Gonatocerus asulcifrons Zeya, 1995 , by original designation.

Diagnosis. Zeyanus is distinguished from the other genera of Gonatocerini by the following combination: head thin, at least 2.5× as wide as long; face without subantennal sulci ( Fig. 267 ); occiput divided by transverse, oblique sulcus extending above foramen magnum from eye to eye; dorsellum triangular; propodeum with straight, submedian carinae more or less converging anterodorsally ( Fig. 270 ); ovipositor distinctly exserted and usually upturned, with numerous setae along the exserted part of each sheath ( Fig. 271 ).

Discussion. Zeyanus belongs to the Gonatocerus group of genera, treated formally as Gonatocerini by Huber (2015). In the Afrotropical region the group also includes Cosmocomopsis , Gonatocerus , Heptagonatocerus , Lymaenon , Octomicromeris and Tanyxiphium . Zeyanus females are unique in the Gonatocerini in having several setae extending along the exserted part of each ovipositor sheath. The only other described genus in Mymaridae with this feature is Australomymar .

Afrotropical hosts. Unknown.

Distribution. No named species in the Afrotropical region. Specimens examined are from Guinea, Kenya, Somalia, South Africa, and Uganda (CNC, SAMC, SANC, UCRC).
