Abstract
Geragnostus tullbergi (Novak 1883), G. cf. ingricus (Schmidt 1894), Arthrorhachis lentiformis (Angelin 1851)?, and Oculagnostus frici (Holub 1908a) are described from the Lower Ordovician Komstad Limestone Formation at Killerod, south-east Scania (Skane), southern Sweden. Geragnostella is a subjective junior synonym of Geragnostus. Conodonts and associated polymerid trilobites suggest the strata yielding these agnostids correlate with the Asaphus expansus Zone or basal A. 'raniceps' Zone of the lower Kunda Stage (uppermost Arenig or lowermost Llanvirn).
