Klikia is a genus of fossil air-breathing land snails, a terrestrial pulmonate gastropod molluscs in the family Elonidae.
This genus is named after Bohumil Klika (1868-1942, also known as Gottlieb Klika), the author of the 1891 book Die tertiaeren Land- und Süsswasser-Conchylien des nord-westlichen Böhmen.
Original description
The genus Klikia was originally described by Henry Augustus Pilsbry in 1895.
Pilsbry's original text (the type description) reads as follows:
Section Klikia Pilsbry, 1894.
Shell depressed-globose, narrowly umbilical, with convex, obtuse spire and round periphery. Surface costulate-striate and minutely papillae in regular diamond pattern. Last whorl constricted behind the lip, which is well reflexed and thickened. Type H. osculum Thomae [de], pl. 71, fig. 49.
This apparently extinct type of Helicodonta is characteristic of middle European Miocene, where it coexisted -with species of Caracollina, such as phacodes Thomae, and with species of typical Helicodonta; H. involuta Thomae being allied to the recent angigyra and biconcava. The strong differentiation of these sectional groups at as early a period as the lower Miocene (when they were, in fact, as strongly differentiated as in the recent fauna), argues a vastly greater antiquity for the genus as a whole. This group is named in honor of Gottlieb Klika, author of an excellent memoir upon tertiary
land and fresh-water shells of Bohemia.
