The compound eye of Simocephalus vetulus was studied with light and transmission electron microscopes. It consists of a about 60-70 ommatidia, each of which comprises a lenticular apparatus, retinula cells with a rhabdom, and pigment cells. The lenticular apparatus consists of a thin cornea, a crystalline cone, and corneogenous cells. Each retinula cell gives rise to a dendrite and an axon. Seven dendrites (which belong to seven retinula cells) unite together to form a rhabdom. The latter is situated beneath the crystalline cone. The rhabdom is structurally characterized by large number of rhabdomeres (microvilli). Rhabdomeres of one retinula cell lie perpendicular to those of another retinula cell. The axons within the optic nerve are the proximal processes of retinula cells. The pigment cell bodies lie close to those of the retinula cells.
