Uncovering Tropical Diversity: Six Sympatric Species of Blepharoneura (Diptera: Tephritidae) in Flowers of Gurania spinulosa (Cucurbitaceae) in Eastern Ecuador

April 14th, 2007

Diversification of phytophagous insects is often associated with changes in the use of host taxa and host parts. We focus on a group of newly discovered neotropical tephritids in the genus Blepharoneura and report the discovery of an extraordinary number of sympatric, morphologically cryptic species all feeding as larvae on calyces of flowers of a single functionally dioecious and highly sexually dimorphic host species (Gurania spinulosa) in eastern Ecuador.
