fussnote | The antennal circulatory organs in the earwigs Labidura riparia Pallas (Labiduridae), Forficula auricularia L. and Chelidurella acanthopygia Gene (Forficulidae) (Dermaptera) represent a functional type that has not been found in other insects. An independent organ exists for each antenna, consisting of a pulsatile ampulla connected to an antennal blood vessel. The ampulla is attached to the frontal cuticle medial to the antenna base and forms a thin-walled sac with a valved ostium on its ventral side. The ampulla wall epithelium is not muscular, but consists of elastic connective tissue. The pumping movements are affected by a precerebral frontopharyngeal muscle, which causes systolic compression of the ampulla upon contraction. The elasticity of both the ampulla and a band of connective tissue, which suspends it in the head capsule, passively effect diastole. The antennal vessel is quite voluminous in the head capsule, but narrows remarkably upon entrance into the antenna. It extends with a constant diameter to the apex, where it opens with a terminal pore. At the base of the vessel, near the ampulla, is a very delicate valve flap which prevents hemolymph backflow during diastole. A comparison of the antennal heart types in insects revealed fundamental differences in the attachments and functions of the associated muscles. In the Dermaptera, the involvement of a precerebral frontopharyngeal muscle suggests an ancestral condition. |
