Lectotype.

ZMB 8378, “Cameruns” [Douala, Region Littoral, Cameroon], coll. Georg Anton Eugen Reichenow, don. Reinhold Wilhelm Buchholz.

Paralectotype.

ZMB 4489. “Boutry” [Butre (Bootry), Ahanta West District, Western Region, Ghana], coll. Hendrik Severinus Pel, don. Hermann Schlegel (Museum Leiden).

Present name.

Hyperolius concolor guttatus Peters, 1875, according to Frétey et al. (2014).

Remarks.

Lectotype by subsequent designation of Laurent (1961: 73). Frétey et al. (2014) corrected the type locality to “Douala” based on an account and a map of Buchholz’ Central African travels provided by Heinersdorff (1880). According to the latter, Buchholz visited “Cameroons” between October 1872 and August 1874. According to Frétey et al. (2014) the collection in RMNH holds four additional paralectotypes (RMNH RENA 1788 A-D) from “Boutry”, coll. Pel (not listed by Gasso Miracle et al. 2007). Drawing in Ahl (1931b: 354, fig. 229) figuring paralectotype ZMB 4489. For the origin, history and status of Hyperolius guttatus and drawings, photographs and redescriptions of the ZMB type specimens we refer to the revision by Frétey et al. (2014).

The Berlin ornithologist Reichenow travelled together with Lühder and Buchholz from spring 1872 on a one year collecting trip to “Akkrá” on the Gold Coast [Accra, Ghana] and the region around “Camaroons” [Douala Region, Cameroon] ( Reichenow 1874; Heinersdorf 1880; Weidmann 1894; Stresemann 1943; see also remarks on Hyperolius acutirostris ). Reichenow was assistant in the fish and reptile department in ZMB until Wilhelm Peters’ death. From 1883 he worked as an administrator and assistant in the mammal and reptile department. In 1888 he became curator for the reptile, bird and mammal exhibition in the new ZMB building on the Ivalidenstraße. After the retirement of his father-in-law Jean Louis Bennoit Cabanis in 1892, and after almost twenty years conducting various activities at ZMB, Reichenow took over as the curator of the ornithological collection ( Stresemann 1943).
