All species of Epicadus Simon, 1895 are reviewed and redescribed, including the previously unknown males of E. rubripes Mello-Leitão, 1924 and E. planus Mello-Leitão, 1932. A new diagnosis based on morphological characters is proposed for the genus. Three valid species of Epicadus are recognized: E. heterogaster (Guérin-Méneville, 1829); E. rubripes and E. planus. The following taxonomic changes are proposed: E. granulatus Banks, 1909 is considered incertae sedis, most likely belonging to a new genus; E. h. scholagriculae Piza, 1933 is considered a junior subjective synonym of E. heterogaster; E. pallidus Mello-Leitão, 1929 is considered a junior subjective synonym of E. rubripes Mello-Leitão, 1924; E. nigronotatus Mello-Leitão, 1940 is considered junior subjective synonym of E. planus Mello-Leitão, 1932. Species distributions were updated with new records in the Neotropics, including Bolivia, Colombia, Ecuador, Mexico, Panama, Paraguay, Peru and Venezuela, which makes Epicadus a genus of Neotropical distribution.
The monotypic linyphiid genus Lomaita Bryant 1948 is redescribed. We present an updated description of the male of L. darlingtoni, the first description of the female and data on its natural history and distribution in the Dominican Republic. We provide a hypothesis on the phylogenetic placement of Lomaita based on cladistic analyses of morphological characters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
