Family Euestheridae Defretin, 1965 Genus Laxitextella Kozur, 1982

Type species: Estheria laxitexta Jones, 1890 .

Discussion.—The generic assignment of the Triassic reticulate forms constitues a difficult problem and most of them are in need of revision. Kozur (1982) erected Laxitextella to include the Triassic European species: L. laxitexta ( Jones, 1890) as the type species, L. ovata ( Lea, 1856) , L. multireticulata ( Reible, 1962) , L. dorsorecta ( Reible, 1962) , and an American species L. forbesi ( Jones, 1862) . According to Kozur (1982) Laxitextella is distinguished by having coarse reticulation sculpture in the growth bands. Laxitextella differs from Loxomegaglypta Novojilov, 1958 in having umbo placed close to the anterior end of the dorsal margin and in ornamentation pattern.
