Abstract

BACCA, Tito; MARULANDA, Jhon Faber  and  DIAS, Lucimar G.. First record of Vacuperniuspackeri (Allen) (Ephemeroptera: Leptohyphidae) from Colombia and South America with additional notes on egg morphology. Rev. acad. colomb. cienc. exact. fis. nat.

In the present study, we recorded for the first time the mayfly species Vacupernius packeri (Allen, 1967) in Colombia and South America describing the egg of this species. The identification was based on nymphs, subimagos, and imagos from Tolima and Caldas, Colombia. The eggs are oval-shaped, with one polar cap, and chorionic plates that are a little overlapped near the uncapped pole but absent near the capped pole. The egg has similar characteristics to the Traverhyphes group eggs, such as chorionic plates slightly overlapped and absent on the chorion surrounding the polar cap. Future phylogenetic analyses would be important to clarify the relationships between Vacupernius and the Traverhyphes group.

Keywords : Pannota; Traverhyphes group; Distribution; Andean region; Eggs, Mayfly.
