Four gynandromorphous specimens of the harvestman Leiobunum globosum Suzuki were found in Japan. One individual from Onuma, Hachimantai, Akita Prefecture and one from Nenokuchi, Towada, Aomori Prefecture, each had male characteristics on the right sides of their bodies, and female characteristics on the left sides. The differences between the two sides were apparent not only in secondary sexual characters but also in accessory sexual characters such as genitalia. These two individuals were obviously typical cases of a lateral gynandromorphism. Also, one individual (specimen A) from Oideen, Towada seemed to be a gynandromorph of the same type. Further, another individual (specimen B) from Oideen, Towada was considered to be a transverse gynandromorph, in which the anterior half of the body was male in character, and the posterior half was female in character. All four specimens were described and figured. Frequent production of gynandry in this species might be related to its probable parthenogenetic development.
