Marcus E 1947 (citation) pg. 163: 'Stylochoplana aulica, n. sp. (Figs. 20-25) with a long stylet (Fig. 25) has most characters of group A. Of this group only St. taruica has a short stylet. The latter species from the Black Sea has a strongly muscular vagina (aulica with scarce muscles) and a Lang's vesicle (wanting in aulica). According to the algae in which they were caught, the specimens showed very different colours. The species feeds upon Amphipods (and Copepods) that also have the same colour aas their habitat. Notwithstanding we cannot explain the adaption of the colour by the colour of the intestine, as the specimens from Sargassum are mottled with single chromatophores.'
