Kalyptea? indica Jain and Maheshwari in Jain et al., 1982

Originally Kalyptea, subsequently (and now) Kalyptea?.
Lentin and Williams, 1985, questionably included this species in Kalyptea.

Holotype: Jain et al., 1982, pl.1, figs.8-9
Age: ?Late Jurassic

Original description (Jain et al., 1982)
Diagnosis - Cyst ellipsoidal, thin-walled, single-layered, folds frequent, surface finely granulate, apical and antapical horns well developed; apical horn longer and broader than antapical horn, gradually tapering,
tip rounded; an ta pi cal horn usually short, narrow, pointed. Central part of cyst inflated-elongate. Kalyptra and apical structures totally absent. Archaeopyle intercallary probably made up of types 2I to 3I
Measurements in µm Holotype/Range
Cyst size 125x165 / 78-125x50-70
Apical horn size 40x16 / 30-50x13-20
Antapical horn size 20x8 / 13-20x8-10
Comparison - Twenty-five specimens belonging to Kalyptea indica Jain & Maheshwari sp. nov. have been studied. The preservation of the forms is not very satisfactory, damaged specimens are frequently
recovered. The species compares best with K. diceras Cookson & Eisenack, 1960 in having unequal horns and thin and finely granulate cyst wall but differs in having inflated elongate central part
and no kalyptra. The rhombic shape of K. glabra (Cookson & Eisenack) Wiggins, 1975 easily distinguishes it from K. indica. Remarks - Morgan (1975) has reported similar single-layered cysts as Fusiformacysta
from the Lower Cretaceous of Australia, having precingular archaeopyle. The species F. salasii is believed by Morgan (1975, p. 164) to be a non-marine dinofiagellate cyst.
