| abstract | Scapheremaeus dirzoius sp. nov. lives on the canopy of trees of Astrocaryum mexicanum Liebm. ex Mart (Arecaceae) and Guarea glabra Kunth (Meliaceae) in the tropical rainforest of Los Tuxtlas, Veracruz, it is similar to S. flamiferus Palacios-Vargas and Ríos, 1998, which lives on epiphytic Tillandsia (Bromeliaceae) from Nicaragua. They differ in the cuticular ornamentation, and the notogastral and ventral chaetotaxy, the new species has only 9 pairs of dorsal setae and 2 pairs of adanal setae versus 10 and 3 pairs in the Nicaraguan species. |
