Diagnostic characters. The male imago can be separated from other species with divided superior volsella by the shape of the accessory lobe of the inferior volsella, AR of 0.74–1.48, an anal point length of 11–48 µm and a clearly sinuate Cu 1. The female can be distinguished from other females with tergite IX divided by broad caudal notch and slight caudal projection of gonocoxites by lacking a strong apical seta on the antenna. The pupa has uneven shagreen spinules on tergal conjunctives III/IV, VI/VII and sternal conjunctives IV/V– VII/VIII, no setae on anal segment, no nose on wing sheath, no stronger spinules or spines on anal segment, female genital sac without spinules, but tentatively associated male exuviae with basiventral but not apical spinules. The larva has a mandible with 3 inner teeth, posterior parapods with 5 claws and antennal blade 2–3 times as long as width of basal antennal segment.

Description. The species will be redescribed in detail by Ferrington and Saether (in manuscript).

Distribution and biology. The species is widely distributed all over the Holarctic and Neotropical regions. In the Neotropical Region the species is recorded from Brazil, Colombia, Costa Rica, Ecuador, Mexico, Peru, Saint Vincent and Venezuela. In addition the species is known from Belgium, Germany, Norway, Thailand and China and all over Canada and U.S.A.

In Brazil it was collected in lowland areas with Amazon forest in the northern states of Pará and Amazonas at altitudes up to 660 m a.s.l.; in the southern states Rio de Janeiro and Santa Catarina it was taken in areas with Mata Atlântica forest . In Costa Rica it was taken in Malaise traps both in a tropical pre-montane wet forest at La Selva and in a cloud forest on the Cacao Volcano at about 1.000 m altitude   .

Reared larvae from Georgia were from moist or saturated soils over lateral lines of a septic system in an urban lawn. It is likely that a larva of this species typically inhabits similar types of moist or saturated organically rich substrate   .
