Wanaea indotata
From Fensome et al., 2019:
Wanaea indotata Drugg, 1978, p.74-75
Originally Wanaea, subsequently Energlynia.
Feist-Burkhardt and Monteil (1997, p.45) retained this species in Wanaea.
Taxonomic senior synonym: Wanaea acollaris, according to Woollam (1980, p.250) — however, Feist-Burkhardt and Monteil (1997, p.45) retained Wanaea indotata.
Holotype: Drugg, 1978, pl.8, fig.12
Isotypes: Drugg, 1978
Locus typicus: Burton Bradstock, Dorset, England
Stratum typicum: Bajocian-Callovian

Original description: Drugg, 1978, p. 74-75
Hypocyst mammilate in form with a prominent antapical horn or protrusion. The epicyst has not been seen intact in side view but is seemingly quite flat to slightly convex upward. Archaeopyle epicystal. Autophragm smooth with sparsely scattered grana or spinulae. The hypocystal paracingular fringe is limited to a very narrow fuzzy rim-like structure. Often it is entirely lacking. Paratabulation absent. The body width ranges from 65 to 117µm with most specimens being about 80 to 85 µm wide. The height ranges from about 60 to 70 µm.
Affinities:
Drugg, 1978, p. 75: Wanaea spectabilis (Deflandre and Cookson) Cookson and Eisenack, 1958, is similar to W. indotata but has a well-defined narrow lacey paracingular flange. W. indotata lacks a paracingular flange entirely or, at best, merely has a fuzzy indistinct rim. It is similar to W. acollaris Dodekova, 1975, in that it lacks a well-defined paracingular structure but differs by not exhibiting paratabulation. It is no doubt closely related to W. acollaris. The simple morphology of W. indotata and its Bajocian occurrence suggests that it is part of an ancestral stock.

Wanaea indotata Drugg, 1978. Diagnosis from Drugg (1978, p.74-75). Hypocyst mammilate in form with a prominent antapical horn or protrusion. The epicyst has not been seen intact in side view but is seemingly quite flat to slightly convex upward. Archeopyle epicystal. Autophragm smooth with sparsely scattered grana or spinulae. The hypocystal paracingular fringe is limited to a very narrow fuzzy rim-like structure. Often it is entirely lacking. Paratabulation absent. Drugg said that it differed from Wanaea spectabilis which has a well-defined narrow lacy paracingular fringe. W. indotata differs from W. acollaris in not having paratabulation. Feist-Burkhardt and Monteil (1997, p.45-46) retained Wanaea indotata, differentiating it from W.acollaris on its reduced ornamentation. In W.acollaris, the spinulae may be proximally or distally interconnected and reach a height of 4.65 µm at the parasutures. Size: width 65-117 µm, with most about 80-85 µm wide, height 60-70 µm.
