Type species

Laqueusplana bocki gen. et sp. nov.

Diagnosis

Pleioplanidae with tentacular and cerebral eye clusters; without tentacles. Male copulatory apparatus directed forward. Seminal vesicle and/or spermiducal bulbs present; penis duct forms a loop between prostatic vesicle and pharynx. Penis stylet long and pointed. Female apparatus usually with vagina bulbosa; Lang’s vesicle present.

Etymology

The name Laqueusplana refers to the term “ laqueus ”, Latin for loop. This is in reference to the loop that the stylet makes between the prostatic vesicle and the pharynx in this genus.

Other species of the genus

Pleioplana megala (Marcus, 1952) also has a forward directed male copulatory system and shows a loop between the prostatic vesicle and the pharynx. Therefore, it must be transferred to the new genus Laqueusplana gen. nov.
