Remarks.

Copelatus apicalis was described by Fairmaire (1898) from Suberbieville [=Maevatanana]. It is classified in the genus Copelatus and currently placed in the Copelatus hydroporoides species group ( Guignot 1961; Nilsson et al. 1997; Nilsson 2001; Nilsson and Hájek 2018). We have studied a male syntype of this species which was not found by Guignot (1961: note 638) and conclude that is not a Copelatus . The syntype male has a stout spine-like setae on a protruding anterodistal corner of protarsomere IV which places it in Madaglymbus ( Shaverdo et al. 2008) and we hereby transfer it to that genus: Madaglymbus apicalis (Fairmaire, 1898) comb. nov.; in fact Guéorguiev (1968: 32) suggested it might belong to Aglymbus “Peut-être c’est une Aglymbus ?" [Eng. translation "Maybe it is an Aglymbus "], which was correct since this was before Madaglymbus was erected for the Madagascar species of Aglymbus ( Shaverdo et al. 2008).
