Drilophaga

Drilophaga Vejdovsky, 1883

Class Monogonontaet: Order Ploimida: Family Notommatidae (ref. ID; 6806)

ref. ID; 1663

Retrocerebral sac absent. Eyespot absent. Foot short and with two toes. Mastax virgate. One species ectoparasitic on oligochaetes, a second ectoparasitic on Eropbdella, and one other possibly free-living. Often covered by a gelatinous secretion. (ref. ID; 1663)

ref. ID; 1923

Corona on a more or less cylindric, retractible prominence, narrow relative to body. Manubria expanded at posterior tips. (ref. ID; 1923)

ref. ID; 3245

Notommatid rotifers with elongate, slender, spindle-shaped, illoricate body, usually without distinct separation of head and body and with very flexible integument; the head is cylindric and elongate, with the mouth at a considerable distance from the front; the tail is rudimentary and the foot very short and apparently unjointed; the toes are minute and conical. The corona is reduced to a simple, circumapical ring of cilia. The mastax is virgate and the trophi of very simple form, usually protrusile and adapted as organs of attachment to the body of the host; rami large and strongly curved, without denticulation on the inner margin; mallei slender and rodshaped, unci reduced to small, oval plates; salivary glands very large. Neither retrocerebral organ nor eyespot are present. At least two of the species are ectoparasitic on oligochaete worms; the third species appears to be free-living. (ref. ID; 3245)
