Collection: Pensoft Publishers

Keywords: Biodiversity hotspots · Topics: Freshwater macroinvertebrate diversity and ecology, Lepidoptera: Biology and Taxonomy, Species Distribution and Climate Change

Two new species of the damselfly genus Archaeopodagrion, A. recurvatum sp. nov. and A. mayi sp. nov., are described from the confluence of the Tropical Andes and the Tumbes-Chocó-Magdalena biodiversity hotspots. Adults differ from the other known species in the shape of female posterior lobe of pronotum and male structures of cerci and paraprocts; the larva differs from other Archaeopodagrion species in the caudal lamellae structure and in the mandibular formula. The two new species are diagnosed, a morphological key to all known males and females in the genus is provided, and geographical distributions are updated. Finally, observations on habitat preferences for each newly described species are provided.
