The ommatidia are of the apposition type with eight similar retinular cells, a fused rhabdom, irregularly orientated rhabdomere tubules and no tracheae. The retinula cells contain lipid. The cone cells have unusual processes, which thicken towards the basement membrane and contain rough endoplasmic reticulum, granules and dense bodies. These processes may act as a primitive transport system for nutrients.14 pagesapplication/pdfen-AU© ElsevierMastotermes darwiniensistermitecompound eyeommatidiaretinula cellrhabdomNorthern AustraliaNew Guinea.197110.1016/S0040-8166(71)80046-0
