A revision of ptychopariid trilobites from the Middle Cambrian of central Bohemia is presented. With a few exceptions, they were previously referred only to Ptychoparia striata. Three genera are recently distinguished: Ptychoparia Hawle & Corda, 1847, Ptychoparioides Růžička, 1940, and Mikaparia gen. nov. Seven species are described: three are revised, four are new, and two is left in open nomenclature; their stratigraphical ranges and significance are discussed. A new stratigraphical subdivision of the Middle Cambrian of the Skryje-Týřovice area is suggested, including three assemblage zones and three barren zones. Four substrate and bathymetrically controlled trilobite associations are recognized in the Skryje-Týřovice area.•

A new lingulate brachiopod assemblage has been found in the early Middle Cambrian Týřovice Greywackes of the Skryje-Týřovice area (Central Bohemia, Czech Republic). A new species, Lingulella agaue sp. n., a minute indeterminable lingulid, a ceratretid Almohadella braunae Streng, 1999, and an acrotretid Treptotreta? sp. have been ascertained in the fauna. Four species in one bed is the most diverse lingulate fauna in the area. Associated faunas indicate a shallow marine nearshore environment with a simple trophic structure dominated by an eoorthid Pompeckium kuthani (Pompeckj, 1896), and a few other epibenthic low suspension feeders, as well as uncommon scavengers and browsers. The presence of Almohadella braunae Streng, 1999 is the first incidence of a ceratretid within territory of the Perunica terrane.•
