Abstract

GARCES, Any Carolina et al. Temnocephala colombiensis n. sp. (Platyhelminthes: Temnocephalidae) from Antioquia, Colombia. Rev. Mex. Biodiv. [online]. 2013, vol.84, n.4, pp.1090-1099. ISSN 2007-8706.  https://doi.org/10.7550/rmb.30259.

Temnocephala colombiensis n. sp., is described as ectosymbiont of Fornácea sp. from San José del Nús, Antioquia, Colombia. Temnocephalans were removed from the mantle cavity and its eggs from the umbilicus and the basal region of the operculum. The new species is characterized by: cirrus curved toward hindbody, approximately 90°; introvert's swelling with 20 to 26 longitudinal rows of fine spines and 11 to13 spines per row; dorsolateral excretory syncytial plates rectangular with rounded corners and excretory pores eccentric, displaced to the anterior portion of the plate. Additionally we have done a comparison of cirrus morphology for Temnocephala described to date, based on literature review. This is the first Temnocephala described from Colombia.
