Re-examination of type material and abundant specimens enable the reinstatement of ‘Conocardium hainense Maurer, 1885’, a species erroneously synonymised with Babinicardia clathrata by Rogalla and Amler. Based on the completely reconstructed morphology, C. hainense can be assigned to the genus Bohemicardia within the Hippocardiidae of the Hippocardioidea. About 600 specimens from a single locality available for study including a wide range of ontogenetic stages allow documentation of allometric growth, with shell width increasing faster than shell height. Protoconchs are not preserved, leaving the development from larval stages to early juveniles unrecorded. The large number of specimens confirms a rather narrow range of morphological variation within the taxon. Based on the preservation of the rarely observed external shell layer, conclusions on shell shape, presence of a hood and external shell ornamentation of the taxon are possible. The material confirms that recognising different shell layer architecture in conocardiid rostroconchs is a prerequisite for specific identification and basic taxonomy.

The geographical distribution of rostroconch taxa of the orders Ribeirioida and Conocardiida, mostly across the equatorial continents and oceans, is compiled for six presumed diversity acmes in the early Early Ordovician (c.485 Ma), the late Early–early Middle Ordovician (c.475 Ma), the Late Ordovician (c.455 Ma), the Early Silurian (c.435 Ma), the late Early–early Late Silurian (c.425 Ma) and the early Early Devonian (c.415 Ma), based on our present, uneven knowledge. Rostroconchs show distribution patterns which enable a provisional separation of biogeographical provinces at least from the Silurian onward, comparable with Late Palaeozoic rostroconch distributional patterns. The distributions of tabulate corals, trilobites and bivalves appear roughly comparable, but not the nektic and planktic groups. A restriction to low latitudes (‘tropical’ realms) is clear for members ofRibeiriaandEopteriain the Early Ordovician, similar to proven patterns for hippocardiid rostroconchs from the Late Silurian onward until the Middle Permian. Preliminary rostroconch provinces or subprovinces, respectively, are currently discernable in the Silurian and Devonian for northwestern Laurentia, south-central Laurentia/Baltica and the north-central margin of Gondwana (i.e. Perunica, Bohemia). Rostroconch distributional data for SE Asia, China, Kazakhstan, Siberia and Australia are sparse and require further studies.
