Litoscalpellum intermedium (Hoek, 1883)

Primary tabs

  • Taxonomical remarks

    Remarks. Foster (1980) inferred that the degree of reduction of the shell plates in L. intermedium increases with growth. After the capitulum reaches about 10 mm in length, the tergum, scutum, upper latus and carinal latus all bifurcate and become more widely separated, as was recognised by Newman & Ross (1971) as typical for the genus Gymnoscalpellum. Unfortunately, the quality of Foster's photographs of the early stages does not allow comparison of shell plate details between his specimens and those of Hoek (1883). Newman & Ross (1971) also noted the similarity between this species and Gymnoscalpellum tarasovi. It is clear that more detailed study of appendage morphology and/or analysis of molecular data is needed to confirm the correct generic placement of this species.
