SpiroporococcusMiller in Miller and McKenzie 1967: 528.
Typespecies Fonscolombia yuccae Ferris 1919, by original designation.
Generic diagnosis:The known immature instars of Spiroporococcusare similar to the same instars of Ovaticoccusin having reduced anal lobes and uniquely shaped enlarged setae. They differ by (character states in brackets are of Spiroporococcus): lacking a concentration of multilocular pores in area surrounding atrium of spiracles (having a concentration of multilocular pores in false atrium of spiracles); usually having four setae on each tibia, without middle seta (with five setae on each tibia, including one in the middle). More information on this genus is provided by Miller and McKenzie (1967). The three known species, S. braggi(Cockerell & Robinson), S. ruber(Parrott & Cockerell)and S. yuccae(Ferris), all occur in the southwestern USA. Further information is provided here for S. braggiand S. yuccae.
Etymology:The generic epithet “ Spiroporococcus” is based on the Greek words “ Spir” meaning “to breathe” or “spiracle,” “ poros” meaning “pore” and “ kokkos” meaning “round” or “scale insect” and refers to the cluster of pores in the atrium of the spiracle.
