FIGURE 2 in Key to sessile gnesiotrochan rotifers: Floscularia (Monogononta; Flosculariidae)

FIGURE 2. Examples of critical characteristics used in differentiating Floscularia species. (See Table 1 for additional information.) A, B. Anterior ends showing features of the corona. A. Corona lateral view of F. conifera: tripartite pellet-forming organ (encircled with dotted line) with a pellet (p) in the modulus; B. Corona ventrolateral view of F. melicerta. C. Presence (F. conifera and F. decora) or absence (F. janus) of mucrons. D. Long peduncle of F. pedunculata; Insert: illustrations of two Floscularia spp. lacking peduncles. E. Examples of trophi showing weekly and strongly differentiated unci teeth. F. Examples of allorecruitive colony formation (three small colonies). Tubes in the upper left colony with rings (Edmondson 1945) for details. Symbols: d = debris; dl = dorsal lobe; f = foot; gt = gelatinous tube: dotted line indicates tube; i = insertion point of peduncle to foot; m = mouth; pd = peduncle; pt = pellet tube; s = substratum; sf = stem female of colony; tr = trophi in mastax; vl = ventral lobe; vla = ventrolateral antenna.
