Cephaloflexa

''Cephaloflexa'' is a genus of land planarians from Brazil.
== Description ==
The genus ''Cephaloflexa'' is characterized by the presence of a cephalic retractor muscle not associated with cephalic glands. Due to this muscle, the head in species of ''Cephaloflexa'' is rolled upwards or backwards similarly to ''Choeradoplana''. 〔Carbayo, F.; Leal-Zanchet, A. M. (2003). ''Two new genera of geoplaninid land planarians (Platyhelminthes: Tricladida: Terricola) of Brazil in the light of cephalic specialisations.'' Invertebrate Systematics. 17: 449-468.〕 The main external feature to distinguish ''Cephaloflexa'' from ''Choeradoplana'' is the presence of two “cushions” on the ventral side of the head of the latter.
The copulatory apparatus of ''Cephaloflexa'' lacks a permanent penis papilla.〔Carbayo, F.; Leal-Zanchet, A. M. (2003). ''Two new genera of geoplaninid land planarians (Platyhelminthes: Tricladida: Terricola) of Brazil in the light of cephalic specialisations.'' Invertebrate Systematics. 17: 449-468.〕
