A new species of terricolous leeches in Japan (Gastrostomobdellidae, Orobdella)
Analysis of the description of Orobdella whitmani Oka, 1895, shows Orobdella kawakatsuorum differs in having iii and iv both 2-annulate, v essentially 3-annulate. The testicular region is posterior to xvii. Evidence is given of digestive enzyme activity in the intestine. The new species is gastroporous, confirming this for whitmani. The function of the gastroporal duct is discussed.
