C. Oncosclera jewelli (Volkmer-Ribeiro, 1963), Neotropical Region, irregularly ovoid strongyles smooth or covered with short spines and tubercles. D. Corvospongilla loricata (Weltner, 1895), Afrotropical Region, slightly curved, stout, spiny strongyles. E. Sanidastra yokotonensis Volkmer-Ribeiro and Watanabe, 1983, Palaearctic Region, oxeas with 2–9 rays rounded to pointed or tricuspidate at tips. F. Spongilla lacustris (Linnaeus, 1759), NearcticPalaearctic Region, oxeas strongly bent with large spines. G. Pectispongilla aurea Annandale, 1909, Oriental Region, botryoidal gemmuloscleres with smooth shaft with at the apex polygonal concavities of the botryum. H. Anheteromeyenia argyrosperma (Potts, 1880), Nearctic Region, birotules with spiny shafts and circular rotules with crenulated to indented margins. I. Corvomeyenia everetti (Mills, 1884), Nearctic Region, pseudobirotules with straight, smooth shafts and pseudo-rotules at the apex (up to 10 hooks). J. Acalle recurvata (Bowerbank, 1863), Neotropical Region, pseudobirotules with cylindrical shaft and hooks of umbonate pseudorotules stout and notably recurved bearing microspines at their apices. K. Dosilia plumosa (Carter, 1849), Oriental Region, birotules with large spines on the straight shaft and flat to slightly umbonate rotules with margins bearing small blunt, recurved teeth (spines). L. Racekiela ryderi (Potts, 1882), Nearctic-Neotropical-Palaearctic Region, birotules with smooth shafts and large disk-like rotules with serrated margins and scattered spines or tubercles. M. Ephydatia muelleri (Lieberkühn, 1855), Afrotropical-Nearctic-Palaearctic Region, birotules with smooth, short shaft and rotules with indented margins. N. Trochospongilla horrida (Weltner, 1893), Nearctic-Palaearctic Region, birotules with smooth, short shaft and approximately circular rotules with irregularly thickened margins. O. Acalle recurvata (Bowerbank, 1863), Neotropical Region, tubelliform gemmuloscleres with the proximal large irregularly circular flat rotule with entire margin supporting a smooth shaft decreasing in thickness toward the distal end shaped as umbonate knob-like rotule with a few teeth. P. Drulia browni (Bowerbank, 1863), Neotropical Region, parmuliform gemmuloscleres with the single circular proximal rotule, with lower concave surface, supporting a distal short acute conical stem (shaft). SEM images. Modified from Manconi and Pronzato (2001, 2002) and Copeland et al. (2015).
