. Bonn zoological bulletin. Zoology. Monoleptoides new genus 189 Thorax. Pronotum pale yellow, yellow or reddish-yellow (Fig. 8a), sometimes yellow basally and a contrasting red- dish colour in the anterior part; 30 % of material with me- dially placed black markings, either in the fonn of a black dot just below the middle (Fig. 8b), or sometimes extend- ed to form a median, longitudinal band (Fig. 8c). Prono- tum broad (Fig. 8d), distinctly convex, median length to maximum width (mean: ), lateral pronotal margins broad. Pronotimi with a distinct, but shallow transverse depression. Elytra pale yellow in two thirds of the material studied (Fig. 8a), others with a transverse black band at the base and another in the apical half of elytra (Fig. 8b, c). Black basal colouration includes the epi- pleura, and rarely also the scutellum (Fig. 8c), which is usually yellow (Fig. 8a, b). Elytra broad, lateral margins distinctly convexly rounded, length of elytron ^.55 mm (mean: ), maximum width of both ely- tra mm ( mm), width of both elytra to length of elytron (mean: ). Legs usually pale yellow, only two specimens with contrasting dark brown tibae and tarsi on all legs. Abdomen. Stemites and pygidium pale yellow to reddish- yellow. Male genitalia. Median lobe broad, widening distinctly sub apically, pointed at the apex and deeply incised (Fig. 8h, i); shallowly sigmoidal in lateral view (Fig. 8g); en- dophallus usually with groups of comparatively short spic- ulae. Female genitalia. Spermatheca with small nodulus and broad comu (Fig. 8j). Diagnosis. A large species, with elytra that are broadly and convexly rounded laterally, and only found in southern Africa. Species that are most similar to M. centromacu- lata are M. duplicata and M. thomsoni. Both species oc- cur sympatrically with M. centromacidata in the south- em DRC, Zambia and Zimbabwe, but neither has been recorded from the Republic of South Africa, where the lat- ter
