We provide the fi rst complete list of the present and lost amphibian and reptile type specimens of the Hessisches Landesmuseum Darmstadt and the Museum Wiesbaden Naturhistorische Landessammlung. The Darmstadt collection currently houses primary types of 5 taxa (holotypes) and secondary types of additional 15 taxa (paratypes). The Wiesbaden collection includes primary types of 13 taxa (8 represented by holotypes, 4 by syntypes and 1 by lectotype). Furthermore, the primary types of 6 taxa formerly housed at the Museum Wiesbaden are considered lost. In several cases, we comment on the current status of the taxa present in the collections. Bufo spinulosus var. arapensis Andersson, 1908 was obviously overlooked and neglected in the literature. It is here considered a junior synonym of Chaunus spinulosus (Wiegmann, 1834). The largest specimen of the type series is designated as lectotype (MWNH 153/1). The current status of Hylambates rufus var. aubryioides Andersson, 1908, as a junior synonym of Leptopelis modestus (Werner, 1898) is rejected.
