Marcus E 1952 (citation) pg.103-104: 'Pseudaphanostoma divae, n. sp. (Fig. 11-14), was found in coarse sand of the
tide-zone, together with the Otoplanid Itaspis evelinae (Fig. 114-125) and the monostyliferous Nemertean
Ototyphlonemertes brevis Correa 1948 on the beach of Ubatuba.  The general shape, the unpaired ovary (o), the
musculous seminal vesicle (s) with invaginated penis (p), the ciliated and also musculous antrum (a), the
terminal or sub-terminal male pore (q), and the brain (c) agree with the type of the genus. Pseudaphanostoma
variabile Westblad 1946.  Differences are:  the measurements (length up to 1.3 mm alive; breadth 0.2 mm),
even, not jerking movements, depressed epicytial nuclei, very numberous cutaneous glands (g), cyanophil as the
frontal (n) and caudal (h) onews, erythrophil oral glands (u), and unpaired testis (t) behind the ovary. The
epithelial nuclei of the ejaculatory duct nearly form half-rings.  The parts of them in the right side
of the body were drawn as they appear in a thick section in Fig. 14, p. Like other inhabitants of the sand, P.
divae has the ventral integument (cilia, epicytium, cutaneous muscles) stronger developed than the dorsal. 
Also the plenty of glands are frequent in animals of the endopsammon (Remane 1940).  The body glands may
provide the mucus that makes the worms glide evenly through the sand.  The secretion of the frontal and caudal
glands is stored in spacious reservatories and evidently sticks the worm to the sand grains shifting in the
breakers.'
