Trematocranus pachychilus, a new endemic cichlid from Lake Malawi (Teleostei, Cichlidae)
Abstract. A new species of Trematocranus, T. pachychilus sp. n., is described from Lake Malawi. So far, it has only been found at Jafua Bay, Mozambique. It can easily be distinguished from T. labifer by its molariform pharyngeal dentition. A morphometric study, including 24 measurements and 15 count...

description | Abstract. A new species of Trematocranus, T. pachychilus sp. n., is described from Lake Malawi. So far, it has only been found at Jafua Bay, Mozambique. It can easily be distinguished from T. labifer by its molariform pharyngeal dentition. A morphometric study, including 24 measurements and 15 counts, was done to compare the new species with T. microstoma and T. placodon. Trematocranus pachychilus is characterised by its thick lips. This species further differs from T. microstoma by its bicuspid (vs. unicuspid) outer oral teeth, wide (vs. small) pharyngeal bone, and its head shape. It resembles T. placodon, from which it can be distinguished by its straight to concave head profile (vs. rounded), less-developed pharyngeal bones (vs. hypertrophied), and the presence of small to minute teeth on the lateral parts of the dentigerous area on the lower pharyngeal bone. A key to the species of Trematocranus is provided. |
