Hyla horstockii Schlegel, 1837: 24, footnote 1.

Hyla horstockii ZMB 3064 (originally 3 specimens), “Cap” [Cape Province, South Africa], coll. Georg Ludwig Engelhard Krebs.

Present name.

Hyperolius horstocki (Schlegel, 1837).

Remarks.

The original catalogue entry of ZMB 3064 made by Martin Hinrich Carl Lichtenstein around 1858 is marked as type of " Hyla Horstockii Schlegel*" from “Cap”, collected by “Krebs”. The original entry was later crossed out and changed to "[ Hyperolius ] Eucnemis modestus , Boutry, Goldküste, [coll.] Pel, [don.] Schlegel" by the same. With this “correction” Lichtenstein probably was referring to Eucnemis modestus Lichtenstein & Martens, 1856 (p. 36, nomen nudum). Likely following the new generic allocation proposed by Tschudi (1838: 35), Lichtenstein and Martens (1856: 36) listed a specimen under the name " Eucnemis Horstockii Schleg." (= Hyperolius horstockii ) with the locality given as “Cap” but without mentioning collector or donor. We reviewed the documents archived in the Historical Research department of the ZMB concerning the correspondence and exchange files of Lichtenstein with Heinrich Boie, Hermann Schlegel and Coenraad Jacob Temminck from the Rijksmuseum van Natuurlijke Historie in Leiden. We could not find any evidence that specimens of the original type series of Hyla horstockii were given to the ZMB. Most probably the specimens under ZMB 3064 (as originally indicated) were collected by the German apothecary and collector of natural history objects Krebs who regularly sent specimens to the ZMB collection during the first half of the 19th century ( Bauer 2000, 2004) and then were erroneously marked as types.
