Simpliciplana is a genus of flatworms in the family Anonymidae.[2][3] It is represented by the single species Simpliciplana marginata.[4] The holotype of the species was collected from Tominado Island, Tawi Tawi, Philippines.[1]

Description

Numerous small eyespots form two irregular groups arranged in the tentacular flap, while slightly larger eyespots form an almost circular cluster over the location of the brain.[1]

It is one of the few cotylean genera lacking ventral suckers, along with some members of Cestoplanidae, members of Theamatidae, Amakusaplana, and, possibly, Chromyella.[5]

Taxonomy

Although described in its original description in 1923 as a member of the family Diplopharyngeatidea,[1] in 1984, Fabel included it in the familty Anonymidae, emending the family to include other genera that, like the already included Anonymus, lacked prostatic glands, vesicles, or prostatoid organs.[3]
