Size up to about 6 cm. The genus contains another species, Z. birabeni, which is seemingly non-orophylous, and can be easily distinguished from Z. fuscus by its coloration (yellowish), size (much smaller) and a pair of letaroventral apophyses on metasomal segment V. The courtship of this species was studied by Peretti (1991).
