| Abstract |
The immature stages of the brown chafers Adoretus tenuimaculatus Waterhouse, 1875 were investigated morphologically using scanning electron microscopy. The scarabaeiform larvae of A. tenuimaculatus are peculiar for bearing a pair of eye spots on the head capsule, devoid of palidium but numerous hamate setae on the raster. The larvae possess a crown-like apical sensory area on each antenna, maxillary and labial palp. The pupa possesses dorsally six pairs of dioneiform organs on the intersegment regions between the first seven abdominal segments. This study provides the first ultra morphological study of the larvae in Adoretini. Both advantages and disadvantages of the scanning electron microscopy in the larval taxonomy of Scarabaeidae were briefly discussed. |
