Paranotila Cleveland

genus / OXYMONADIDA / POLYMASTIGIDAE

Description

Paranotila is a cell ( 15-25 J.Jm) longer than Monocercomonoides and smaller than Notila (Figs . 6A,B). It bears 4 anterior flagella deflected backward , a slender axostyle not protruding Figs . 4. Ultrastructural characters of oxymonads . Fig . 4a . Section of Monocercomonoides showing the two pairs of basal bodies/flagella (8, B') separated by the preaxostylar lamina (P) from which arise the microtubules of the axostyle (A) near the nucleus ( N); microtubules of the pelta (Pe), microtubular fiber (arrow) underlying the recurrent flagellum (R) (bar= 1 1-Jm) .

The large nucleus containing 2 nucleoli lies anteriorly near the origin of the flagella and the axostyle. There is no para- basal and this genus is an oxymonad. It presents a sexual cycle close to that of Notila : the cell undergoes gametogenesis forming 8 male and 8 female pronuclei which fuse producing zygotic nuclei and after division 8 diploid cells (Fig . 68). Considering the sexual cycle , this genus is closer to Notila but the cytological features indicate a similarity with Polymastigidae. One species described : P. lata in Cryptocercus punctulatus (Cleveland , 1966) . No EM study.
