Original description: [Cookson and Eisenack, 1982] (translated from German):

Deflandrea tubifera n. sp.
Plate 3, Figs. 12-14

Type: The specimen shown on Plate 3, Fig. 12, and preserved in specimen Meadow Station Bore No. 9.
Diagnosis: A species of the genus Deflandrea, flattened in shape, longer than wide, with a roughly triangular epitract and a trapezoidal hypotract. The lateral margins of the epitract are often convex. The epitract terminates in a short, distinct tubule (Fig. 14). The hypotract has a broad, but pointed antapic horn; the other is indicated in many places as a broad, short cusp. The belt (cingulum), which separates the epitract and hypotract at its widest point, is quite broad but only slightly depressed, formed by low folds of the periphragm. A longitudinal groove (sulcus) is absent. The archaeopyle is almost circularly rounded and quite large. The endophragm is oval, longer than wide; it usually touches the periphragm laterally. The endophragm and periphragm are thin, delicate, and unpaneled. The periphragm bears granules that are not very densely spaced. Only very rarely are these arranged in rows, as in the paratypoid at the top right in the apical region, suggesting concealed paneling.
Material and dimensions: Numerous specimens in the same preparation. Type: Length: Width 107:67 μ, paratypoid 114:70 μ. Other specimens are approximately between 80:50 and 117:73 μ (8 measured).
Occurrence: Meadow Station Bore.
