Key to species of the genus Piribelba

1. Notogastral setae setiform, straight or slightly bent, without attenuated and flagelliform tips. Setae of anogenital shield strong and quite long, adanal setae reaching level of insertions of subsequent pairs. Body length 550–670; Mongolia, China............................................................................. P. crassisetosa ( Bayartogtokh, 2000) .

– Notogastral setae slightly to strongly bent, fine, attenuated up to curly tips. Setae of anogenital shield fine and shorter, adanal setae not reaching level of insertions of subsequent pair...................................................... 2

2. Lamellar setae with rare, dark, small scales or bristles (often difficult to see) on dorsal side. Lamellar setae setiform, not flattened or extended. Prodorsal costulae anteriorly strongly bent inwards. Dorsal setae of proximal segments of legs III and IV strong, with spinuli, scales or bristles, but not flattened. Body length 690–790; Russia................................................................................................. P. rossica ( Bulanova-Zachvatkina, 1962) .

– Lamellar setae covered by well visible multiple, dark, scales or bristles on dorsal side. Lamellar setae sometimes proximally distinctly flattened and broadened. Prodorsal costulae slightly bent. Dorsal setae of proximal segments of leg III and IV often flattened, broadened, lanceolate, with dentate margins, usually covered by dense spinuli or bristles. Body length 605–730; Europe ( Austria, Italy, Slovakia)................................................. P. piriformis ( Mihelčič, 1964) .
