Vitsika is a Malagasy genus of ants in the subfamily Myrmicinae.

The queens may be alate or ergatoid, or both forms may occur within a single species.

Two species (V. manifesta, V. suspicax) exhibit morphological intermediates between alate and ergatoid forms, and two species (V. acclivitas and V. crebra) appear to be polygynous.

[2] Worker-associated males are known for V. crebra, V. breviscapa and V. labes.

Similar in size to the conspecific worker or slightly smaller.
