''Dugesia aborensis'' is a species of freshwater triclad found in the Abor Hills, Arunachal Pradesh, India.〔Whitehouse, R.H. (1913). XXII Freshwater planaria. ''Records of the Indian Museum'' 8: 317-321, plate 22.()〕 ''Dugesia aborensis'' was originally described as ''Planaria aborensis'' by Whitehouse. In 1928, Meixner changed the genus to which it more likely belongs.〔 Meixner, J. (1928). "Der genitalapparat der tricladen und seine beziehungen zu ihren allgemeinen, Morphologie, Phylogenie, Okologie und Verbreitung". ''Z. Morph. Okol. d Tiere'', 11, pp. 570-612.〕 Because there is no description of ''D. aborensis'' copulatory apparatus, it should be considered as ''species inquirenda''. ==Description== ''D. aborensis'', like all the other ''Dugesia'' species, has a triangle-shaped head with two auricles on each side. The dorsal side of the body has a light brown color, with a darker line running in the middle line along the length of the body, from the neck to the posterior end. At the root of the pharynx, at about the middle of its course, this line expands into a broad patch. The ventral surface has a milky white color. They have two eyes in two pigment free-patched areas in the middle of the head. This species was described on the basis of animals without male reproductive organs and without genital aperture. However, the ovaries were detected between the anterior branches of the gut. The analysis of the ''D. aborensis'' specimens sections revealed no oviduct or uterus.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dugesia aborensis」の詳細全文を読む スポンサード リンク
