Acanthoscelides oblongoguttatus (Fahraeus), 1839

( Figure 2 )

According to Johnson (1983a) this species is one of the largest in the genus, and it is the only one in the oblongoguttatus group. The V-shaped glabrous area on the vertex, the structure of the male genitalia, and its preference for seeds of Acacia ally this bruchid to species of Mimosestes . Our field observation showed that instead of producing a mass of eggs, A. oblongoguttatus oviposits individual eggs on pods as do many other bruchids.
