abstract

  • The hoplonemertean genera Prosadenoporus Burger, 1890 and Pantinonemertes Moore and Gibson, 1981 are revised and synonymized based on a morphological re-evaluation. We redefine Prosadenoporus Burger, 1890 on the basis of characters held in common by the eight species: Prosadenoporus agricola (Willemoes-Suhm, 1874) comb. nov., Prosadenoporus arenarius Burger, 1890, Prosadenoporus spectaculum (Yamaoka, 1940) comb. nov., Prosadenoporus winsori (Moore and Gibson, 1981) comb. nov., Prosadenoporus enalios (Moore and Gibson, 1981) comb. nov., Prosadenoporus mooreae (Gibson, 1982b) comb. nov., Prosadenoporus mortoni (Gibson, 1990) comb. nov. and Prosadenoporus fujianensis (Sun, 2001) comb. nov. We describe a new semi-terrestrial species Prosadenoporus floridensis sp. nov. from Belize and Florida and compare its morphology to other species of Prosadenoporus. The average sequence divergence of P. floridensis sp. nov. from other congeners is 9.15% (16S) and 10.65% (COI) and 7.8% and 10.3% respectively from the nearest sequenced congener P. mortoni.
