Figure 1

Molecular phylogeny of Pontohedyle with morphological and ecological data plotted. A. Maximum-likelihood tree of the genus Pontohedyle generated with RAxML for the concatenated dataset (28S rRNA, 16S rRNA, COI) analyzed in three partitions. Bootstrap support (BS) above 75 given below nodes (BS within MOTUs shown only for VIII). · eyes externally visible (as in Figure 1B); eyes not visible externally; lateral radula tooth with denticle (see Figure 1E); Δ lateral radula tooth without denticle (see Figure 1C,D); Hydrography: red = tropical, blue = temperate. Geography: East-Pacific = yellow, Central Indo-Pacific = light-green, Central-Pacific = turquoise, West-Pacific = dark green, Mediterranean and Black Sea = blue, Red Sea = pink, Indian Ocean = purple, West Atlantic = dark brown, East Atlantic = light brown, Habitat: intertidal = brown, subtidal = beige. B. Living Pontohedyle milaschewitchii. C.-E. Scanning electron microscopy of Pontohedyle radulae, arrowhead indicates denticle in lateral plate of radula, numbers mark lateral cusps of rachidian tooth. C.- D. Radula of P. verrucosa. E. Radula of P. milaschewitchii. cc = central cusp of rachidian tooth, dg = digestive gland, ey = eyes, llp = left lateral plate, ot = oral tentacles, rlp = right lateral plate, rt = rachidian tooth.
