WebThe rectal complex of the mealworm is an example of the ‘cryptonephric’ condition, wherein the distal ends of the Malpighian tubules are closely applied to the rectum and enclosed with it in a special chamber, the perinephric space, which is separated from the rest of the body cavity by the perinephric membrane. WebJan 1, 2024 · Malpighian tubules (MTs) and the hindgut together constitute the excretory system of insects. Larvae of lepidopterans (butterflies and moths) demonstrate the so-called cryptonephric arrangement, where the distal blind end of each MT is embedded into the rectal complex.
