摘要

The compound eye of Coptotermes formosanus Shiraki alates is approximately round, and is composed of 300～400 ommatidia. The compound eye of the female is larger than that of the male. Each ommatidia with facet quadrate to hexagonal irregularly. The biconvex cornea has ～30 layers, and the outer layer is smooth and slightly curved, whereas the inner layer is greatly curved. The crystalline cone is of the eucone type with four cells. Retinas are of the apposition type and are positioned directly below the cones at a distance of ～100～120 μm, and consist of eight retinular cells around the rhabdom. Many tracheae are assembled as a tapetum near the basement membrane.

有翅型家白蟻的複眼之外部形態約略為圓形，雌蟲的複眼較雄者略大。每隻複眼由300～400個小眼所組成，每一小眼面呈不規則的四角形到六角形。依其縱剖面由外而內之次序，最外層為外平內凸約30層的角膜。角膜之下有四個圓錐晶體細胞，當亮適應時，周圍包圍大量的色素粒，圓錐晶體之下為網膜，8個網膜細胞組成的視官柱體厚約100～120 μm，周圍包圍有色素細胞。基底膜附近有氣管集結。
