Distribution maps were created for species of the Mithracidae family on the Caribbean and Pacific coasts of Costa Rica, based on exploratory samplings and spatio-temporal records of collections (1960 to 2016) provided by the Universidad de Costa Rica’s Museum of Zoology. In addition, phylogenetic relationships were explored using a multigene concatenated phylogenetic tree based on mitochondrial and nuclear gene fragments. Historical records reveal the presence of 24 species of mithracid crabs and their geographic distribution in the Pacific and Caribbean of Costa Rica, including islands on the continental and oceanic shelf. Molecular analyses confirm sister relationships between the clades Ala-Maguimithrax, Omalacantha-Microphrys, Omalacantha+Microphrys-Teleophrys, and a well-supported clade of species belonging to the genus Mithraculus. However, our concatenated molecular data set suggests a monophyletic relationship between Thoe, Petramithrax, and Hemus, differing from what was previously reported. The results obtained in this study will help in the development of strategies for the environmental protection of these marine resources, by providing a baseline for monitoring environmental degradation and destruction of habitats used by spider crabs on the coasts of Costa Rica. Furthermore, the molecular information obtained in this study will help future studies focusing on understanding the population genetics, phylogeography, regional gene flow, and divergence among species between the Caribbean and Pacific coast. El objetivo de este estudio fue determinar la distribución, riqueza e identificación molecular de cangrejos araña en las costas Pacífico y Caribe costarricenses. Se realizaron mapas de distribución de especies de la familia Mithracidae en las costas del Caribe y Pacífico de Costa Rica a partir de muestreos exploratorios y registros espacio-temporales de colectas (1960 al 2016) suministrados por el Museo de Zoología de la Universidad de Costa Rica (UCR). Además, se obtuvo un árbol filogenético mediante topología concatenada multigénica de fragmentos de genes mitocondriales y nuclear. Los registros históricos revelan la presencia de 24 especies de cangrejos mitrácidos y su distribución geográfica en el Pacífico y Caribe de Costa Rica, incluyendo islas de la plataforma continental y oceánica. Los análisis moleculares confirman relaciones de parentesco entre los clados Ala-Maguimithrax,Omalacantha-Microphrys,Omalacantha+Microphrys-Teleophrys y el clado bien soportado de las especies del género Mithraculus. Los resultados generados en este estudio contribuyen con información para el desarrollo de estrategias futuras de protección ambiental de los recursos marinos, al aportar una línea base para el monitoreo de la degradación ambiental y la destrucción del hábitat de cangrejos araña en las costas de Costa Rica. La información molecular obtenida, a futuro permitirá estudios de genética de poblaciones, filogeografía, flujo génico regional y divergencia entre especies del Caribe y Pacífico. O objetivo deste estudo foi determinar a distribuição, riqueza e identificação molecular de caranguejos-aranha no litoral costarriquenho do Pacífico e do Caribe. Foram realizados mapas de distribuição de espécies da família Mithracidae nas costas do Caribe e do Pacífico da Costa Rica a partir de amostragens exploratórias e registros de espaço-tempo de coletas (1960 a 2016) fornecidos pelo Museu de Zoologia da Universidade da Costa Rica (UCR). Além disso, foi obtido um posicionamento taxonômico por meio da topologia multigênica concatenada de fragmentos genéticos mitocondriais e nucleares. Registros históricos revelam a presença de 24 espécies de caranguejos Mithracida e sua distribuição geográfica no Pacífico e Caribe da Costa Rica, incluindo ilhas da plataforma continental e oceânica. As análises moleculares confirmam relações de parentesco entre os clados Ala-Maguimithrax, Omalacantha-Microphrys, Omalacantha+Microphrys-Teleophrys e o clado bem apoiado de espécies do gênero Mithraculus. Os resultados gerados neste estudo contribuem com informações para o desenvolvimento de futuras estratégias de proteção ambiental dos recursos marinhos, fornecendo uma linha de base para o monitoramento da degradação ambiental e a destruição do habitat do caranguejo-aranha no litoral da Costa Rica. As informações moleculares obtidas, no futuro, permitirão estudos de genética populacional, filogeografia, fluxo genético regional e divergência entre espécies do Caribe e do Pacífico.
