To arrive at a better understanding of gastrotrich
systematics and phylogeny, we performed the first cladistic analysis of nearly all known gastrotrich
genera using 71 morphological characters.
Cosmopolitan complexes of cryptic species have been already shown for several species of meiofaunal metazoans without larvae such as nemerteans (Leasi, Andrade, & Norenburg, 2016), gastrotrichs
(Leasi & Todaro, 2009), nemertodermatids (Meyer-Wachsmuth, Curini-Galletti, & Jondelius, 2014) and annelids such as Hesionides gohari (Westheide, 1974; Schmidt & Westheide, 1999), Microphthalmus listensis (Westheide & Rieger, 1987), Nerilla antennata, (Goodrich, 1912; Schmidt & Westheide, 1997/98), and Petitia amphophtalma (Westheide & Hass-Cordes, 2001; Westheide & Schmidt, 2003).
The rest of taxa: nauplii larvae, gastrotrichs
, kinorhynchs, polychaetes, oligochaetes and cumaceans exhibited low relative abundances (below 1%) and scarce taxonomic representation.
Protists, nematodes, rotifers, small crustaceans, tardigrades, gastrotrichs
, turbellarians, oligochaetes, and insect larvae are regularly found from psammon habitats (Thane-Fenchel, 1968; Whitman and Clark, 1984; Schmid-Araya, 1998, Kotwicki et al., 2005a, 2005b).
Molecular phylogenies sometimes recover other groups such as rotifers and gastrotrichs
nested within the core lophotrochozoans (e.g., Passamaneck and Halanych, 2006), although these groups sometimes fall outside, as sisters to the core group taxa (e.g., Paps et al, 2009).
