摘要:
Acroukrainicus sagittiferus gen. ef sp. n. from a loamy-sand soil in Ukraine is described on the basis of light and scanning electron microscopy. The new genus is placed in the Cephalobinae and distinguished from all other genera in the subfamily by the possession of three pairs of lips, each lip flat and three-lobed (asymmetrically triangular); primary axils narrow; secondary axils broad; and three pointed labial probolae, each probola shaped as an arrow-head with one rounded lateral tine on each side and a concave abaxial prominence.
