Popis: Key to species by shell characters of Landouria species in northeastern Thailand Finally, in order to facilitate future field research, we provide a dichotomous key for the identification of the currently known Landouria species in northeast Thailand. 1. Shell lustrous, peripheral keel absent, brown band present............................................................................................................................................... L. diplogramma (Möllendorff, 1902) comb. nov. – Shell not lustrous, peripheral keel absent, brown band absent......................................................... 2 2. Peripheral keel blunt...................................................................................... L. chloritoides sp. nov. – Peripheral keel sharp......................................................................................................................... 3 3. Peripheral keel slightly sharp, shell surface with numerous tiny tubercles.... L. tuberculata sp. nov. – Peripheral keel very sharp, shell surface without tubercles.............................................................. 4 4. Shell relatively large with low spire, shell surface with radial scaly processes............................................................................................................................................... L. trochomorphoides sp. nov. – Shell relatively moderate in size with high spire, shell surface without radial scaly processes....... 5 5. Keel more sharp and distinct with its downward bent rim................................... L. elegans sp. nov. – Keel sharp, without downward bent rim........................................................................................... 6 6. Suture indented, growth line obvious................................................................................................................................................................ L. strobiloides C. Tumpeesuwan & S. Tumpeesuwan, 2019 – Suture not indented, growth line obscure........................................................... L. circinata sp. nov.
