Lophyrus megalepis Bleeker 1860: 327

= Gonocephalus megalepis ( Bleeker, 1860)

Syntype: RMNH.RENA.3954 , Arch. Ind . [Oost Indische Archipel], don. Bleeker [coll. Ludeking]

Type locality: Agam, West Sumatra, Indonesia

Remarks: Until now a specimen deposited under NHMUK (formerly BMNH) 1946.8.27.21 (male, “East Indian Archipelago”, Dr. Bleeker) has been considered as the holotype by monotypy of Gonocephalus megalepis as well as the holotype by monotypy of Tiaris tuberculatus Günther, 1872 , a junior synonym of Gonocephalus megalepis (see Manthey & Denzer 1991, Uetz et al. 2019). However, Bleeker (1860) did not state how many specimens he had nor did he report any measurements that could help identify a holotype of Gonocephalus megalepis . Our discovery of a second specimen from Bleeker’s collection implies that the NHMUK and Naturalis specimens both constitute syntypes of Gonocephalus megalepis . This is corroborated by the fact that the specimen is also listed as type in the catalogue of incoming material INK.RMNH.RENA 503 (Book 8, p. 11, under Lophyrus melapogon [sic]): “Typische Exemplare [type specimens] van Rept. en Amph. uit de collectie [from the collection of] Dr. Bleeker in ruil [in exchange] van Prof. Dr. Fürbringer, April 1880 ”. The specimen was additionally identified as type in 1959 by R. F. Inger, Chicago in the handwritten catalogue. According to the original publication ( Bleeker 1860) the locality and collector should be given as Agam, Sumatra, coll. Ludeking.
