Lectotype ( Fig. 1 ) of Omaloplia nitida , ♀ , here designated: “Brasilia Sarra da Lappa [sic] / Ménétr. / Syntype / http://id.luomus.fi/GAC.37962 Univ. of Helsinki LUOMUS, 2024 / Photographed 2024 LUOMUS Pekka Malinen / Lectotype ♀ Omaloplia nitida Mannerheim, 1829 det. Pacheco & Ahrens 2024” (deposited in the Finnish Museum of Natural History LUOMUS, Helsiniki , Finland ). Remarks. The lectotype is the only known extant specimen from the original type series. It is a female, which makes the species concept difficult to reconcile with any of the other species in the genus with a similar general appearance. It is likely a senior synonym of one or more of the other species of Blepharotoma , but this can only be resolved in the context of a complete taxonomic revision of the genus. The lectotype shares all characteristic features of Blepharotoma ( Fig. 1 ), last investigated by Smith (2008) . The lectotype was collected in one of the Langsdorff expeditions in Brazil , at the locality “Serra da Lapa” ( Mannerheim 1829 ; Papavero 1971 ), which is now probably “Serra do Cipó”, Minas Gerais State , Brazil . It was probably collected either from 16 October–4 December 1824 or 3 January 1825 ( Papavero 1971 ; Smith 2016 ).
