【 摘 要 】

Gorgona National Natural Park comprises Gorgona and Gorgonilla Islands, located in the Colombian Pacific at 35 km from mainland. A large-scale study was conducted in Gorgona including samples from benthos and aereal nets and traps during five fieldworks. We here focus on the family Leptophlebiidae, describing two new species and giving data of four additional species. Terpides iguapoga sp. n. is described and illustrated from nymphs and adults, and can be characterized by the following characters, in the nymph fore trochanter and femur with row of strong spine-like setae on inner margin, gills with blackish tracheae, posterolateral projections present on terga VI and VIII–IX; in the adult upper portion of eyes orangeish white, forewing membrane hyaline tinged with yellowish around crossveins and marginal intercalary veins, genitalia with penes abruptly narrowing on distal third. Thraulodes insular sp. n. is described from nymphs and adults and diagnosed as follows, in the nymph abdominal gills with narrow lamellae, femora with black streak near apex; in the imago forewing costal area basal to bulla without crossveins, a spot and a band on femora, terga II–VI translucent white, terga VII–X darker, posterior margin of subgenital plate triangular, penes spines short and robust. We give new geographic records for four additional species Farrodes caribbianus, Farrodes roundsi, Hagenulopsis esmeralda and Hagenulopsis zunigae. Ecological data and distributional maps are provided. Leptophlebiidae presents a reduced diversity in relation to mainland; in general the species recorded show a geographic relation to the Chocoan-Caribbean and Andean mayfly faunas.
