Druggidium rhabdoreticulatum
Druggidium rhabdoreticulatum Habib, 1973
Originally (and now) Druggidium, subsequently Raphidodinium.
Below, 1987, transferred this species to Raphidodinium Deflandre, 1936. Lentin and Williams, 1989, retained it in Druggidium.
Holotype: Habib, 1973, pl.2, fig.6
Locus typicus: DSDP-site 105, Hatteras Abyssal Plain, N Atlantic
Stratum typicum: Valanginian-Albian
Original diagnosis: Habib, 1973, p.53
Small proximate dinoflagellate cysts with polygonal outline. Average C.I. is 25; range from 24 to 29. Average W.L.R. is 0.81; range from 0.76 to 0.88; W. L. R. of inner body ranges from 0.72 to 0.85. Cyst tabulation ?", 0a, 6", ?c, 6""", 1p, 1""""; archeopyle and operculum as for genus. Septa low and straight, or gently sinuous; not crenulate. Tract covered over its entire surface by a raised microreticulate membrane supported by short distally recurving baculae. Opercular pieces are adherent at the cingulum in approximately 75 percent of the examples. Forty measured specimens range in maximum diameter from 29 to 40 Ám.
