Notes for Aberrantospermata Convolutidae
Graff L v 1905 (citation)- "Acoela with two genital openings, the female lying anterior the male, with a bursa seminalis, with ovaries or with ovaries and yolk glands. The mouth lies always on the ventral side somewhat back from the end of the body. The bursa seminalis either lacks a chitinous nozzle or these are present in one, two or a greater number. Only in Plychoerus are the two ovaries formed into separate ovar and yolk parts. With the single exception of Convoluta the testes occur always as separated follicles. In general the family is organically much more complex than the Proporidae and includes mostly broad and flat forms distinguished by a well developed parenchymal musculature. Length from 0.6209 mm. Littoral or pelagic." Bohmig L 1908 (citation)- p 7 mentions. Bresslau E, Reisinger E 1928 (citation)- p 37, fig 13- plan of organization of this family. Karling TG 1940 (citation)- mentions p 223, 224. Marcus E 1946 (citation)- compares Convolutidae with Macrostomidae and discusses relationship.

Outer muscle layer with an outer circular and inner longitudinal muscle layers. Male copulatory organ with muscular tube shaped penis, often very glandular. Through lack of a seminal vesicle, this is formed as a direct inpocketing of the epidermis, a ciliated male antrum absent in their cases. Otherwise turned inward into a seminal bursa or a muscular penis sac. Male reproductive opening ventral, superterminal or terminal at posterior end." List of genera- 1. Convoluta 8. Faerlea 15.
