The tribe Stegaspidini Haupt, 1929 (Hemiptera: Membracidae: Stegaspidinae) and three included genera, Bocydium Latreille, Lirania Stal, and Smerdalea Fowler, are described and illustrated based on adult and nymphal morphology . Bocydium has 15 valid species, including B. duoglobum Cryan, new species; Lirania is monotypic; and Smerdalea has 4 valid species, including S. immi nens Cryan, new species. The genus Smerdalea is transferred from the tribe Microcentrini to Stegaspidini; a description of the previously unknown nymp h of S. elevata Cryan is given. Updated taxonomic keys for the tribe and fo r the genera Bocydium and Smerdalea are presented; complete species checkli sts are compiled, with synonymies, for each genus.
