A new nematode species of the family Cylindrocorporidae and the genus Mycto
laimellus from subcortical cavities made by the locust borer (Megacyllene r
obiniae Forster) in black locust (Robinia pseudoacacia L.) is described. Ma
les of the new species have a length of 700 to 1,050 mum; a bursate tail, p
eloderan with nine pairs of rays; and knobbed, curved spicules with tips be
nding gently into a hook. The distinctive gubernaculum is half the length o
f the spicules, deeply grooved longitudinally along both its dorsal and ven
tral surfaces, and has a spoon-shaped end. Females have a length of 830 to
1,340 pm, an amphidelphic reproductive tract with long ovaries crossing eac
h other to extend beyond the equatorial vulva, and a gradually tapering tai
l.
