Diagnosis. Odontochrydium irregulare  ( Figs 1A, 1BView FIGURE 1) differs from O. bicristatum  sp. nov. ( Figs 1C, 1DView FIGURE 1) by

having the unmodified median mesoscutal area (with two longitudinal ridges in O. bicristatum  ( Fig. 6DView FIGURE 6, 7DView FIGURE 7)), the mesoscutum evenly punctate (vs. reticulate-foveate, with enlarged foveae medially on median area of mesoscutum); the metasoma evenly punctate, with mid-sized punctures ( Figs 2AView FIGURE 2, 4AView FIGURE 4, 5AView FIGURE 5) (vs. with scattered, large punctures ( Figs 6AView FIGURE 6, 7AView FIGURE 7)). It differs from the Indian O. xui  sp. nov. by having the metasomal tergite 3 surface in lateral view evenly bent (vs. forming a concave angle at pit row level in O. xui  ) and longer MS (1.5 – 1.6 × MODAbout MOD) (vs. 1 × MODAbout MOD).

Distribution. Angola, Democratic Republic of Congo, Kenya, Malawi, Namibia, South Africa, Uganda, Zimbabwe.

Remarks. Odontochrydium irregulare  is widespread in the south-eastern Afrotropical Region ( Kimsey & Bohart 1991; Madl & Rosa 2012). The species is rather variable in colour and shape of the apical teeth on metasomal tergite 3 ( Kimsey & Bohart 1991). In particular, the coloration varies from blue to green or purple, and the median apical tooth may be stouter with a trace of a median longitudinal carina ( Fig. 2FView FIGURE 2) or acute with a median carina ( Fig. 4FView FIGURE 4) (form described as O. trautmanni  , synonymised by Kimsey & Bohart 1991). I observed a third variation (specimen from the Democratic Republic of Congo) with median tooth distinctly longer and wider than the lateral teeth. O. irregulare  , although widespread, is quite an uncommon species, seemingly known through a limited number of specimens. It is therefore difficult to evaluate whether the described variations match with the range of variability of O. irregulare  , or conversely represent different, closely related species. A future investigation based on more material is required.
