Abstract
We describe three new species of Nanomis based on nymphs from Colombia using the characteristics that distinguish them from other species of the genus: Nanomis antoniae Salinas, sp. nov.: left mandible with incisors fused with 7 denticles; right mandible with an outer set of incisors with 3 denticles, inner set with 8 denticles; labial palp with segment III elongated and rounded; the outer margin of the fore femur with a row of 18–19 clavate setae; the inner margin of the fore tarsus with a row of spine-like setae, the most basal setae serrate; posterior margin of terga I-IV smooth, with spines on terga V-X. Nanomis mariquitensis Salinas, sp. nov.: left mandible with incisors fused with 9 denticles; right mandible with an outer set of incisors with 4 denticles and inner set with 9 denticles; labial palp with segment III elongated and rounded; outer margin of the fore femur with row of 8–9 clavate setae; inner margin of the fore tarsus with a row of spine-like setae, the two most basal setae serrate; posterior margin of terga I-IX smooth with spines on tergum X. Nanomis quindiensis Salinas, sp. nov.: left mandible with incisors fused with 7 denticles; right mandible with an outer set of incisors with 3 denticles, inner set with 9 denticles; maxillae with one small simple setae near medial hump; labial palp with segment III wide and rounded; outer margin of the fore femur with row of 14–15 clavate setae; posterior margin of terga I-II smooth, with spines on terga III-X.
