Abstract

Stoiba Spaeth, 1909 is revised with a phylogenetic analysis of 38 adult morphological characters for nine Stoiba species and 11 outgroup species (Mesomphaliini, Ischyrosonychini, and Hemisphaerotini). Four Cuban species of Stoiba were not sampled. Parsimony analysis located the four most parsimonious trees. The strict consensus (CI=0.59, RI=0.78, Steps=83) resolved the monophyly of Stoiba. The monophyly of Stoiba is supported by pale yellow antennae, antennomere VII broader than its length, and rounded basal line of pronotum. An illustrated key to ten species of Stoiba is provided along with a distribution map of 11 species. Stoiba rufa Blake is synonymized with S. swartzii (Thunberg) by a morphological comparison which includes female genitalia.
