Glomodinium
From Williams et al., 2017:
[Glomodinium, Dodekova, 1975, p. 26
tax. jr. synonym of Pareodinia Deflandre, 1947, according to Stover and Evitt, 1978. Dörhöfer and Davies, 1980, and Davies, 1983, retained Glomodinium as a separate genus.
Type species: Glomodinium reticulopilosum, Dodekova, 1975 (pl.5, figs.1–2)]
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Dodekova, 1975]: (Translation: LPP):
Diagnosis:
Sphaeroidal to subsphaeroidal body with apical horn. Antapical protrusions are lacking. The body has two-layered wall. The endophragm is thin and may be distinguished in the base of the apical horn. The periphragm is thicker, forms the apical horn and the ornamentation. No traces of furrows and tabulation. The ornamentation on the periphragm is represented by granules, spines, fine reticulum with septa along the ribs or hair-like processes. The surface of the periphragm may be smooth.
The archaeopyle is intercalary, composed of three plates (type 3I).
Affinities:
The existence of intercalary archaeopyle, composed of 3 plates, apical horn and ornamentation distinguish the new genus from genus Pareodinia and from all known in the literature genera. The intercalary archaeopyle -3I- determines the new taxon to Peridiniacean dinoflagellate lineage (Wall and Dale, 1968). The genus Glomodinium resembles genus Cometodinuim Deflandre and Courteville, but by the latter apical horn and information about the archaeopyle is lacking, while distinct cingulum is established.
