            In this study, the members of ant genus Lophomyrmex in Thailand are revised. Four species of the genus are recognized in the country. They belong to the following two species-groups: Lophomyrmex bedoti species-group (L. bedoti Emery, 1893; L. lucidus Menozzi, 1930; and L. striatulus Rigato, 1994) and Lophomyrmex quadrispinosus species-group (L. birmanus Emery, 1893). Many new localities are given for all species. A key to the species is provided based on the worker caste. Morphological and ecological information is presented for each species. Moreover, distribution pattern of the four species is also given. All species of the genus found in Thailand nest in the soil and prey on other arthropods. Therefore, the ant activity promotes changes the soil structure and nutrients.
