Two new eriophyoid mite species (Trombidiformes: Eriophyoidea) from the cocoa tree, and a note on Shevtchenkella biseta (Nalepa)

[EN] Two new eriophyoid mite species are described from the cocoa tree, Theobroma cacao L. (Malvaceae) ¿ the Diptilomiopidae Davisella trevisani n. sp. Rodrigues, Navia & Oliveira, from Brazil; and the Eriophyidae Tetra theobromae n. sp. Rodrigues, Navia & Oliveira, from Costa Rica. The new Davisella species presents an enlarged subcylindrical tubercle bearing pedipalp genual seta d, a novel structure for eriophyoid mites; its functional morphology was discussed. The new Tetra species is the third in this genus described from plants of the Malvaceae. A closer look at Shevtchenkella biseta (Nalepa), described from the Malvaceae Hibiscus rosa-sinensis L., showed its taxonomic assignment to the Phytoptidae, Sierraphytoptinae and raised a hypothesis on its synonymy.To Dr. Philipp Chetverikov and Dr. James Amrine for valuable suggestions related to the new taxa, functional morphology of original traits and taxonomic reassignments. To Dr. Enrico de Lillo and anonymous reviewer for valuable suggestions that greatly contributed to improving the manuscript.
