Marcus E 1949 (citation) Pg. 94 - 'Convoluta westbladi, n. sp. (Fig. 7-10) from the sand of the upper littoral of
the island of São Sebastião is a small, whitish worm, up to 0.4 mm in length and 0.1-0.2 mm in breadth.  The
position of the epidermice nuclei is normal in the most part of the body; the peripherical parenchyma
(ectocytium) is vacuolized and poorly developed.  Cyanophil rhabdoids are disposed between the epidermic
cells, as are the pigmented rods of Anaperus tvaerminnensis (Luther 1912). The sensory cells are even more
richly develped than in C. vexillaria Marcus (1948).  As in C. viridipunctata Westbl. the two anterior
germ-centres flow backwards in the ventro-median line and form an unpaired ovary.  The testes continue paired
from the germ-centres and extend dorso-laterally.  The penis is directed forward and is invaginated into a
muscular bulb that contains sperms (seminal vesicle, Fig. 8, u) and granular secretion (g).  The nozzle of the
bursa is small (0.008 mm.) and lies horizontally.  It opens into a vacuole of the parenchyma close to the most
developed ovocyte.  C. saliens Graff and C. vexillaria Marc. seem to be the nearest related species, but both
have paried ovaries and no hermaphroditic germ centres.  Also the vagina of saliens and the nozzle of saliens
and vexillaria differ fro the corresponding organs of C. westbladi.'

Hooge M.D. & Rocha C.E.F. 2006 (citation) p. 12 - report this species from the coast of Sao Paulo, Brazil.
