Four new Nearctic species of the fungus gnat genus Tetragoneura Winnertz, 1846 were discovered in eastern North America. Tetragoneura polyspina Taber is known from Canada and the northern United States, Tetragoneura canada Taber is known only from its boreal namesake country, Tetragoneura dixie Taber is known only from the austral United States, and Tetragoneura caligula Taber is known only from the Great Lakes region of the United States. With the two recently described species Tetragoneura caliga Taber and Tetragoneura lustra Taber, and the designation of Tetragoneura nitida Adams, 1903 as a nomen dubium, a total of six Nearctic species of this genus are currently known.

A new Nearctic species of the fungus gnat genus Tetragoneura Winnertz, 1846 was discovered in western Michigan, USA. More than 100 males and seven females of Tetragoneura lustra spec. nov. flew to a Malaise trap over the course of several years in an ecotone between swamp and second-growth forest. The new species resembles published accounts of Tetragoneura nitida Adams, 1903, which is relegated
herein to the status of nomen dubium. Juvenile stages of T. lustra are unknown.

Two new species of Boletina Staeger fungus gnat were discovered in western Michigan. Adult males of both species flew to a Malaise trap in spring and a second generation of one species flew during the transition from late summer to autumn. The habitat was an ecotone between swamp and second-growth forest dominated by black ash (Fraxinus nigra Marshall), paper birch (Betula papyrifera Marshall), red maple (Acer rubrum L.), and black cherry (Prunus serotina Ehrhart). Females and juvenile stages of Boletina dentata Taber and Boletina tricinctoides Taber are either unknown or have not been described.

One male and four females appeared in a Malaise trap in mostly deciduous woods in spring. Docosia fimbria Taber with its orange and black coloration resembled Docosia dichroa Loew and the newly discovered Docosia walpurga Taber, but male and female terminalia and wing venation indicated specific differences. Females of all three species were associated by comparative anatomy with males, and seasonal phenology was determined.1 aTaber, Stephen, W. uhttps://sciaroidea.myspecies.info/node/5056901139nas a2200121 4500008004100000245008500041210006900126300001200195490000700207520072500214100002300939856005500962 2012 eng d00aA New Nearctic Species of Boletina Staeger Fungus Gnat (Diptera: Mycetophilidae)0 aNew Nearctic Species of Boletina Staeger Fungus Gnat Diptera Myc a159-1700 v373 a

A second new species of Boletina Staeger fungus gnat was discovered in western Michigan following the discovery of Boletina michigana Taber in the same habitat at the same time of year. Males and females were collected in early spring in a Malaise trap in a paper birch (Betula papyrifera Marshall)-red maple (Acer rubrum L.)-black cherry (Prunus serotina Ehrhart) woods adjacent to black ash (Fraxinus nigra Marshall) swamp and cattail (Typha latifolia L.) marsh. Boletina setacea Taber will key out to Boletina sciarina Staeger by using one of two old keys, but male terminalia and wing venation indicated a specific difference.

Docosia walpurga Taber resembles Docosia dichroa Loew but male terminalia and female coloration indicate a specific difference instead. A remarkable and yet-unidentified empidid fly that seems to mimic the fungus gnat was found with the new species.1 aTaber, Stephen, W. uhttp://www.bioone.org/doi/abs/10.3958/059.036.040700997nas a2200121 4500008004100000245007600041210006900117300001200186490000700198520059200205100002300797856005500820 2011 eng d00aA New Species of Boletina Staeger Fungus Gnat (Diptera: Mycetophilidae)0 aNew Species of Boletina Staeger Fungus Gnat Diptera Mycetophilid a335-3490 v363 aA new species of Boletina Staeger fungus gnat was discovered in western Michigan. Adult males and females were collected in early spring in a Malaise trap in a paper birch-red maple-black cherry woods adjacent to black ash swamp and cattail marsh. The late March collection date is the earliest reported from the eastern United States for any species of the genus according to the literature examined.
