2. Additional setae, if present, only on lateral rims of prodorsum, i.e. on soft integument; only one pair of setae on sclerotized in - area ( Fig. 105 ; Uusitalo 2010: fig. 120); two baculiform solenidia on tarsus I ( Fig. 113 ). ( setigera -group). Dorsal setae plumose ( Fig. 106 ); tip of solenidion ω1 bent sideways on tarsus I ( Fig. 113 ); two piliform solenidia on femur I................................................................................. L. shibai nom. nov. (= B. ramosus Shiba, 1976 )

- Additional setae inserted all over prodorsum, i.e. on both soft integument and sclerotized parts of area of setae in ( Figs. 119 , 133A ; Uusitalo 2010: fig. 130); three baculiform solenidia on tarsus I ( Fig. 125 ; Uusitalo 2010: fig. 133). ( arbusculosa -group). Anterior pair of sensilla ve branched ( Fig. 119 ); adult more than 500μm in length ( Fig. 120 ); baculiform solenidia distant from each other and piliforms missing on tibia II ( Fig. 126 ); famulus distally on tarsus I ( Fig. 125 )............. L. furcula sp. n.
