New subgenera and a new species of the genus Raphignathus Dugès (Prostigmata, Raphignathidae), with taxonomic notes on the genus Neoraphignathus Smiley & Moser.

Four new subgenera in the genus Raphignathus Dugès are hereby proposed: Raphignathus (Raphignathus), subgen. nov. , Raphignathus (Monoraphignathus), subgen. nov. , Raphignathus (Diraphignathus), subgen. nov. , and Raphignathus (Triraphignathus), subgen. nov. These subgenera are diagnosed by the number of setae on the interscutal membrane of females. A new species, R. (D.) neohecmatanaensis sp. nov. , is described and illustrated based on females collected from Ziziphusspina-christi Mill. (Rhamnaceae). The taxonomic status of the monotypic genus Neoraphignathus Smiley & Moser and three species ( R.evidus , R.hsiufui , and R.johnstoni ) are discussed. A key to world species of the family Raphignathidae is given.
