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 Stoiba swartzii (Thunberg) by a morphological comparison which includes female genitalia.
Highlights

We provide a new definition of Stoiba as well as notes on ten species and synonymize S. rufa with
We examined a total of 200 Stoiba specimens from 15 museums and collections; museum acronyms (Table 1) follow Evenhuis (2012)
Summary
Stoiba Spaeth 1909 was erected for Chelymorpha flavicollis Klug, 1829. Spaeth noted that he did not have other species on hand but that Chelymorpha swartzii Thunberg 1808 and Chelymorpha angusticollis Suffrian, 1868 might belong in this new genus. Suffrian (1868) described Chelymorpha fimbrialis Suffrian and Chelymorpha lurida Suffrian from Cuba. Blake (1930) described Stoiba bruneri Blake, S. quatuordecimmaculata Blake, and S. indivisa Blake from Cuba. Borowiec (1999) classified these two as Stoiba species. Later, she added S. fascicollis Blake and S. marginata Blake from
