SPECIES, AUTHORITY D. septoconstrictus Kalgutkar 1993, p. 72, pl. 4.1, fig. 18.
LOCATION Peel River, Yukon Territory, Canada.
ORIG DESCRIPTION* Dicellate, aporate, dark brown, simple, smooth-walled spores; slightly tapering at both ends; noticeably constricted in the middle of the septum; septum about 3 µm thick. Both cells ellipsoidal to navicular. Spore size 20-28 x 7-10 µm.
COMMENTS* This species is somewhat similar to Dicellaesporites aculeolatus Sheffy & Dilcher 1971 but differs in being larger in size, and in having a thick wall without small irregular folds. However, the size range of D. aculeolatus was based on only two specimens.

Etymology: From the Latin, septum, wall; constrictus, contracted, referring to the spores being constricted at the septum.
