A new species of Mathevotaenia (Cestoda, Anoplocephalidae, Linstowiinae) from the lizard Sceloporus malachiticus (Squamata, Phrynosomatidae) from Panama

Mathevotaenia panamaensis sp. nov. (Cestoda, Anoplocephalidae, Linstowiinae) from a green spiny lizard, Sceloporus malachiticus , collected in Panama is described. This is the first species of Mathevotaenia reported from a lizard host. The new species is most similar to Mathevotaenia bivittata in that mature eggs are concentrated along the lateral margins of the proglottids. Major differences between the two species include oval cirrus sac in M. bivittata , a spherical cirrus sac in M. panamaensis ; ovary compact consisting of 10–15 short lobules in M. bivittata , ovary bilobed with each lobe consisting of 3–4 lobules in M. panamaensis .
