Distribution

San Clemente Island, La Jolla, California; La Ensenada, Baja California, Mexico.

Habitat

Benthic.

Remarks

Diplandros singularis has cerebro-tentacular eyes and a double male reproductive system located in the anterior part of the paired male gonopore. In addition, it has an interpolated prostatic vesicle and a Lang’s vesicle oriented towards the anterior region of the body.

Hyman (1953a) was the first to describe the species, placing it in the family Leptoplanidae Stimpson, 1857 . However, she noted that the internal morphological arrangement of Diplandros is based on the internal plan of Notoplanides (review the comments of Amyris favis).
