Notes.

About twenty described species. We define this genus in a broader sense than Bechyné (1958b) did. He separated Pseudadorium from Hemipyxis Chevrolat on the basis of the distinctly vertically orientated elytral epipleura alone; not visible laterally in dorsal view (horizontally orientated and visible in lateral view in Hemipyxis ). However, the elytral epipleural configuration is variable. Other diagnostic characters are more useful for separating these two genera, such as: frontal carina not extended towards the clypeus (Fig. 244) in Pseudadorium [extended in Hemipyxis (Fig. 193)]; frons distinctly raised distally (Fig. 244) in Pseudadorium [not raised in Hemipyxis (Fig. 193)]; elytra with distinct basal calli in Pseudadorium (absent in Hemipyxis ); pronotum with anterior angles distinctly thickened and produced towards anterior (Fig. 243) in Pseudadorium [slightly thickened and not distinctly produced towards the anterior in Hemipyxis (Fig. 192)]; hind tibiae narrowly and less deeply channeled dorsally in Pseudadorium (Fig. 245) [broadly and more deeply channeled in Hemipyxis (Fig. 194)]. The following species from Madagascar, previously attributed to Hemipyxis , are here transferred to Pseudadorium : Hemipyxis balyana (Csiki in Heikertinger and Csiki 1940: 461) = Pseudadorium balyanum (Csiki in Heikertinger and Csiki 1940) comb. n.; Hemipyxis brevicornis (Jacoby, 1892a: 573) = Pseudadorium brevicornis (Jacoby, 1892a) comb. n.; Hemipyxis cyanea (Weise, 1910b: 439) = Pseudadorium cyaneum (Weise, 1910b) comb. n.; Hemipyxis gynandromorpha Bechyné, 1958c: 195 = Pseudadorium gynandromorphum ( Bechyné, 1958c) comb. n.; Hemipyxis latiuscula Bechyné, 1958c: 195 = Pseudadorium latiusculum ( Bechyné, 1958c) comb. n.; Hemipyxis soror (Weise, 1910b: 469) = Pseudadorium soror (Weise, 1910b) comb. n.
