Lithochytrina Ehrenberg, 1846: 385 [as a family]; 1847: 53 [as a family]. Lychnocanioidea – Petrushevskaya 1986: 132-132 . — Afanasieva et al. 2005 : S295-296. — Afanasieva & Amon 2006: 144 . DIAGNOSIS. — Lithochytridoidea consist of two- to three-segmented Nassellaria with a stout vertical apical horn, a spherical cephalis, a conical or globular thorax, as well as three feet or a relevant structure. The feet are principally connected to the D- and double L-rods of the cephalic initial spicular system. Expect for a few exceptions, an aperture is present. REMARKS The Lithochytridoidea consists of the Bekomidae and Lithochytrididae . Based on the results of the molecular phylogeny, Lamprotripus and Dictyopodium (= Pterocanium in original) form a tight, single group ( Sandin et al. 2019 ).
