Remarkable fly (Diptera) diversity in a patch of Costa Rican cloud forest: Why inventory is a vital science

Publications Posted on: April 26, 2018
Study of all flies (Diptera) collected for one year from a four-hectare (150 x 266 meter) patch of cloud forest at 1,600 meters above sea level at Zurquí de Moravia, San José Province, Costa Rica (hereafter referred to as Zurquí), revealed an astounding 4,332 species. This amounts to more than half the number of named species of flies for all of Central America.

A dolichopodid hotspot: Montana's Milligan Creek Canyon

Publications Posted on: January 10, 2017
In southwest Montana, near the town of Three Forks, Milligan Creek cuts a small and seemingly mundane notch through dry limestone hills. Milligan Creek is unassuming and small enough to be effortlessly stepped over in most places. In fact, it flows underground for much of its 4-5 mile journey to the Jefferson River.

Liancalus Loew, 1857 and Scellus Loew, 1857 (Insecta, Diptera, DOLICHOPODIDAE): Proposed conservation of the names by designation of Dolichopus regius Fabricius, 1805 as type species for Anoplomerus Rondani, 1856 [Case 3681]

Publications Posted on: August 03, 2015
The purpose of this application, under Article 81.1 of the Code, is to conserve the genus-group names Liancalus Loew, 1857 and Scellus Loew, 1857 (Diptera, DOLICHOPODIDAE), widely distributed and well-established genera of dolichopodid flies whose names have been used consistently for more than one-and-ahalf centuries.

Taxonomy of long-legged flies (Diptera: Dolichopodidae)

Projects Posted on: April 22, 2015
This research seeks to collect, identify, describe, and classify species of long-legged flies (Dolichopodidae), an important and diverse group of insects. 

A revision of the Nearctic species of Liancalus (Diptera: Dolichopodidae)

Publications Posted on: March 17, 2015
The genus Liancalus Loew is revised for the Nearctic Region. Seven species are documented from this region including two new species: Liancalus genualis Loew, L. hydrophilus Aldrich, L. limbatus Van Duzee, L. pterodactyl sp. n., L. querulus Osten Sacken, L. similis Aldrich, and L. sonorus sp. n. Lectotypes are designated for the following species: L. genualis, L. hydrophilus, L. querulus, and L. similis.

Revision of the Nearctic species of Nepalomyia Hollis (= Neurigonella Robinson) (Diptera: Dolichopodidae: Peloropeodinae) with a world catalog

Publications Posted on: October 03, 2011
Nepalomyia Hollis and Neurigonella Robinson are synonymized. The genus Nepalomyia is more fully characterized and the Nearctic species are revised. Nepalomyia nigricornis (Van Duzee) and N. sombrea (Harmston & Knowlton) are reassigned and redescribed. Two new species, N. dilaticosta Runyon & Hurley and N. hesperia Runyon & Hurley, are described.

Richard L. Hurley, 1934-2008

Publications Posted on: December 08, 2009
Richard Lester Hurley, dolichopodid worker and friend to everyone, passed away on September 3rd at the age of 74. He was born on June 22, 1934 in Sault Ste. Marie, Ontario and received a B.A. in biology from Queen's University in Kingston, Ontario in 1957. For his senior thesis, he conducted an insect survey of the Lake Opinicon region.

The cingulum: A unique structure of some Dolichopodidae

Publications Posted on: December 08, 2009
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.

A review of Erebomyia (Diptera: Dolichopodidae), with descriptions of three new species

Publications Posted on: June 30, 2009
The genus Erebomyia is reviewed and a key is provided for the four known species, three of which are described here: Erebomyia aetheoptera n. sp., E. akidoptera n. sp., and E. ramseyensis n. sp. The type species, E. exalloptera Runyon & Hurley, is redescribed and the male genitalia illustrated.

A new genus of long-legged flies displaying remarkable wing directional asymmetry

Publications Posted on: January 16, 2009
A previously unknown group of flies is described whose males exhibit directional asymmetry, in that the left wing is larger than, and of a different shape from, the right wing. To our knowledge, wing asymmetry of this degree has not previously been reported in an animal capable of flight. Such consistent asymmetry must result from a leftÂright axis during development, a level of differentiation whose existence has been questioned for insects.
