| abstract | A new species of Lohmannia, L. maya n. sp., from mangrove soils in Mexico is described and illustrated. It is morphologically similar to L. similis Balogh, 1962, L. jornoti Mahunka, 1985 and L. lanceolata Grandjean, 1950 but differs from these species in having lateral and posterior setae wide in their proximal half and thin in their distal half, ending in a sharp tip, and a continuous notogastral band S8. It also has a smaller body size (727 μm) compared with the three aforementioned species (790, 810 and 840 μm respectively). The 11 species of the genus Lohmannia recorded from the Americas were compared, a key for them is included, and some ecological notes for the new species are also provided. |
