Energlynia acollaris
Energlynia acollaris (Dodekova, 1975) Sarjeant, 1978
Now Wanaea. Originally (and now) Wanaea, subsequently Energlynia.
Tax. sr. synonym of Energlynia kyrbasia Sarjeant, 1976, the original type species of the genus Energlynia, according to Fensome, 1981, and Fenton and Fisher, 1978. Energlynia acollaris therefore becomes the correct name for the type species of Energlynia, but the nomenclatural type of the genus remains the holotype of Energlynia kyrbasia.
Tax. sr. synonym of Energlynia indotata (Drugg, 1978) Fensome, 1981, according to Woollam, 1980, and Riley and Fenton, 1982.
Tax. sr. synonym of Wanaea zoharensis Conway, 1978, according to Fensome, 1981.
Holotype: Dodekova, 1975, pl.3, fig.1-4
Locus typicus: Borehole C-32, Dolina, NE Bulgaria
Stratum typicum: Late Bathonian
Original description: Dodekova 1975, p. 20: Wanaea acollaris
Broad-conic proximo-chorate cyst. In the present description the conception of Evitt (1967, Pl.10, figs.4-6) for the orientation of the cyst is accepted, based on the known models for the new origin of the archaeopyle. The obscure traces of tabulation in the new species confirm this orientation. The epitract is flat and rounded, short and occupies 1/5th or 1/6th of the cyst length. Reminds of a peculiar lid of the large and well-formed hypotract. On the epitract occur several (4 or 5) apical and ? intercalary plates, as well as 5 or 6 precingular plates. The hypotract is an overturned cone with broad base which terminates in distinct antapical horn. The cingulum is located in the broadest part of the cone, narrow and obscure. In some specimens a slight concavity with weak or absent ornamentation is established only on the hypotract which probably marks the place of the sulcus (Pl. III, fig.5). On the hypotract 5 or 6 postcingular plates and one antapical plate are observed. The existent fossil material did not enable a specifiction of the reflected tabulation to be made but a combined schematic model is shown in text-fig.2. The ornamentation of the membrane is represented by different in dimension granules and spines. They are best developed in the area of the cingulum and on the sutures where they reach a length of 4.65 Ám. Neighbouring spines may join in the proximal or distal ends. The archaeopyle is epitractal.
Dimensions: length 65-86 Ám; breadth: 67-100 Ám; length of apical horn: 8-12 Ám.
Fensome, 1981, p. 50
Synopsis of diagnosis: A species of Energlynia with a broadly conical or mamillate hypotract with or without an antapical horn, and a small epitract, which may possess a poorly defined apical horn. Tabulation is ussually faintly indicated by low ridges or rows of short spinelets, indicating a formula: 1-?", ?2a, 6"", 6""", 1p, ?1-2"""". However, tabulation may be absent. The posterior cingular suture may be slightly more distinctly marked than the other sutures. Surface ornamentation is shagreenate, or with scattered granulae or spinulae.
Affinities:
Dodekova, 1975, p. 21: The lack of cingular fringe distinguishes Wanaea acollaris from all known species of the genus.
Fensome, 1981, p. 50-51: (annotated) Dodekova, 1975 and Sarjeant, 1976 both gave a tentative tabulation pattern of E. acollaris.
