Type species. Galleruca lausoniae Fabricius, 1798, by present designation.
Current status. Synonym of Altica Geoffroy, 1762.
Comments. The generic name Adimus Billberg, 1820 is a completely forgotten name. Billberg (1820a) listed 24 names in Adimus, of which twelve are nomina nuda and two unavailable one-letter names of varieties. As shown above, 11 available names are now classified in well known genera: Mimastra, Hoplasoma, Aulacophora, Phyllobrotica, Sermylassa, Cornubrotica, Macrohaltica, and Agelastica, all of them described after Adimus. The only available name with still unclear identity remains Galleruca lausoniae Fabricius, 1798, described from “ India orientalis”. This name disappeared from the entomological literature. We know only two very old publications where it is listed (Perty 1831, Sturm 1843). We studied the three syntypes, one male and two females, deposited in ZMUK and they are undoubtedly belonging to the genus Altica Geoffroy, 1762. The two females belong to a different species with respect to the male. After the examination of the tignum, the vaginal palpi, and the spermathecae, the two females resulted to be attributable to the taxonomically critic couple “ aenea -birmanensis ”, more probably to the species birmanensis (Jacoby, 1896) because the morphometry and the color pattern fit better with this species (Reid & Beatson 2015). The male, instead, is characterized mainly for having very large eyes and this feature allows to attribute it without doubt to the couple “ caerulea - gravida ” (Reid & Beatson, 2015). Unfortunately, the aedeagus is missing, but considering some external characters (i.e. elytra and hypomeron shining, without microsculpture) and the geographical distribution (Altica gravida (Blackburn, 1896) is occurring only in Australia), this male can be considered as belonging to the species Altica caerulea (Olivier, 1791) with increased confidence. It is in agreement with Sturm (1843) who also considered lausoniae (reported as Graptodera lawsoniae (Fabricius)) conspecific with caerulea (Olivier) but with reversed precedence. Because the type series of Galleruca lausoniae consists of two species we designate the male as lectotype to fix the species identity (for the photo of the lectotype see Figs 4–5). The correct synonymy is as follows, senior synonym first: Altica caerulea (Olivier, 1791) = Galleruca lausoniae Fabricius, 1798. Because the type species of Adimus was never designated, we propose Galleruca lausoniae Fabricius, 1798 as its type species and, consequently, the following synonymy is established: Altica Geoffroy, 1762 = Adimus Billberg, 1820 syn. nov.
