Internal morphology and histology of the fish mite Lardoglyphus konoi (Sasa and Asanuma) (Acarina: Acaridiae). I. Digestive system.

The female and male reproductive systems are described from serial paraffin sections. A bursa copulatrix, a receptaculum seminis, a pair of ovary, oviducts, and a median genital opening {:onstitute the female reproductive system. Accessory glands as in some other acarids are absent in the female reproductive system of L. konoi. A pair of filiform glands are present at the mouth of the receptaculum seminis. A pair of testes, accessory glands, vasa deferentia, and a common ejaculatory duct ending in a median penis constitute the male reproductive system. Morphologically the two accessory glands are different and evidences are given for the functional dissimilarity between them
