Abstract

Two new species of Stenochironomus are described based on adult males, one from the Colombian Andes and the other from the Brazilian Amazon: Stenochironomus miraflores sp. nov. and Stenochironomus nukini sp. nov., respectively. Both species share diagnostic features with Stenochironomus impendens, suggesting a close affinity; however, they can be readily distinguished by differences in coloration patterns and hypopygial morphology. Additionally, two new country records for Colombia are reported, one from the Llanos biome and the other from a transitional area between the Amazon and the Andes. These findings increase the known diversity and distribution of Stenochironomus in Neotropics and reinforce the importance of expanding systematic sampling efforts in poorly explored and under-sampled areas across the Neotropical region.
