Isarachnanthus panamensis Carlgren, 1924: 190-193, 195; Carlgren 1940: 6, 11, 13-14; Molodtsova 2003: 251; Stampar et al. 2012: 1-2

Type locality.

Taboga, Panama (Pacific coast).

Distribution.

Only known from shallow water at the type locality

Remarks.

This species was described from the Panama coast based on three specimens. The description is also detailed, including two mesentery diagrams. Thus, variation in mesenterial organization is quite evident, especially in relation to the size of directive mesenteries. As discussed above, regarding Isarachnanthus bandanensis , these two species are very similar in terms of both morphological and molecular data and further studies are needed.
