ABSTRACT
The morphology and ultrastructure of the compound eye of the predatory bug, Montandoniola moraguesi (Puton, 1986) was investigated using scanning and transmission electron microscopy. Its compound eyes, which contain â¼195 ommatidia per eye, have the following characteristics each ommatidium possesses a laminated corneal lens measuring â¼9 µm in diameter and â¼7 µm in thickness, a tetrapartite eucone crystalline cone, which is approximately 5.5 µm long, like a dumbbell with the distal end larger than the proximal end, eight clustered retinula cells â¼25.6 µm in length, two primary pigment cells and eight secondary primary pigment cells. The rhabdomeres of the eight retinula cells form a circular, tiered rhabdom of two elongated and six peripheral retinula cells. The rhabdomeres of cells R7 and R8 are distributed along the basolateral surface of the cone and form a centrally-fused rhabdom that spans nearly the full length of the ommatidium. The microvilli of the peripheral rhabdom (R1-R6) are radially arranged and form a bilobed, V-like shape in the central rhabdom. Based on the similarity of the compound eye of M. moraguesi to the eyes of other predatory insect species, the evolution and function of eyes in predators are briefly discussed.
