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
).
