Two new species of the genus Laelaptonyssus Womersley from North America and Australia, with observations supporting the reinstatement to family level of the subfamily Laelaptonyssinae sensu lee, 1970 (Acari: Mesostigmata: Rhodacaroidea).
The rhodacaroid genus Laelaptonyssus is rediagnosed and descriptions are provided for two new species, i.e. Laelaptonyssus setosus sp. nov. and Laelaptonyssus hallidayi sp. nov, taken from the host termites Reticulitermes flavipes and Porotermes adamsoni. Morphological observations supporting the validity of Womersley's family Laelaptonyssidae are presented, along with a key to known species and notes on biological relationships.
