Title: The cingulum: A unique structure of some Dolichopodidae

Author: Runyon, Justin

Date: 2008

Source: Fly Times. 41: 3.

Publication Series: Miscellaneous Publication

Description: The cingulum is a U-shaped structure of unknown function which arises between abdominal sterna 4 and 5 and terminates in a pair of variously modified flag-like appendages. This structure is well developed only in males of the genus Scellus. Richard Hurley discovered that Hydatostega have a much reduced cingulum, a finding that had broad implications for elucidating hydrophorine phylogeny. Rich suggested that the size and bright coloration might serve a visual signaling function, whereas the arrangement of hairs suggests a pheromone-dispersing function.

Keywords: Dolichopodidae, cingulum
