A remarkable new genus Manzumbadoa gen. n. from Costa Rica

Summary The sciarid Manzumbadoa bradysioides gen. et sp. n. from Costa Rica is described. This new genus is outstanding for its wing venation that is unique not only among the Sciaridae but all the Sciaroidea. In particular, the presence of the fused radio-media (frm) in Manzumbudoa bradysioi&j is most remarkable as no other species of the Sciaridae shows this character. Manzumbadoa belongs to a group of genera around Bradysia WINNERTZ, the phylogeny of which is still poorly understood.
