Diagnosis. Small, short-legged midges (less than 6.0 mm). Body covered by a dense vestiture of hairs and setae, but less so in Sycoracinae. Head with reniform eyes connected by an eye bridge (Psychodinae) or with circular eyes (other subfamilies); antennae with 14-16 segments, often adorned with single or paired ascoids; mouth parts non-functional, except in Sycoracinae (blood-sucking on amphibians and reptiles). Wings oval with 9-10 longitudinal veins and almost no cross-veins; anal area reduced; R with four (Sycoracinae, Trichomyiinae) or five branches (Psychodinae); M with three branches; wings in rest held roof-like over abdomen but flat in Sycoracinae and almost all Telmatoscopini and Pericomini. Adults of Psychodinae with hump-backed appearance because of reduced sternite 1. Male genitalia not inverted in Sycoracinae, inverted by torsion of egments 7 and 8 in Trichomyiinae, and inverted by torsion of segment 9 in Psychodinae. The rear margin of the male head in some genera of Psychodinae with permanently inverted structures (cornicula), that play a role in courtship behaviour, as well as further structures (permanently or accidentally eversible patagia and tegulae) on the male pro- and mesothorax. Some of these are covered with hairs and setae of contrasting colour, others produce pheromones. Coloration and pheromones play a decisive role in courtship behaviour. Larvae of Psychodinae are heavily sclerotized and consist of 26 or 27 body 'rings' (pseudosegments or annuli). The pattern of hairs and setae on the segments often is specific, so that the larvae of Psychodinae are determinable down to species level. Larvae of Trichomyiinae are vermiform. Larvae of Sycoracinae are very small and asselliform.

Biology. The metapneustic larvae prefer moist or aquatic environments near ponds, lakes, streams, and even in man-made habitats. Main larval requirements are food, a substratum on or in which they can move, and almost permanent contact with atmospheric oxygen. There are four larval instars. Sycoracinae are univoltine and their larvae live in moss carpets near springs and natural wetlands along streams and small unpolluted rivers. Trichomyiinae are univoltine and their larvae are restricted to dead and decaying wood, preferably of old willow and alder. In the Psychodinae most species of the Pericomini and Telmatoscopini are univoltine in Northern Europe, but in Central Europe up to two generations per year may develop, and even more in Southern Europe. Psychodini in general are polyvoltine. Larvae feed on decaying organic matter, those of Psychodini prefer the eutrophic conditions of the dung of ungulates and a few of carnivores, some are abundant even in sewage treatments works (e.g., the trickling filter fly, Psychoda (Tinearia) alternata). However, most may be classified as collectors, or micro-shredders of almost every kind of decaying organic matter in streams. There are numerous adjustments to ecological conditions in different genera or species, that enable larvae to survive even under conditions of fast flowing alpine streams. Adults are weak flyers.

Note 1 The previously used name Pericomini is preoccupied by the Dermapteran subfamily Pericominae (derives from the genus Pericomus). The use of Pericomaini as an alternate spelling follows Sabrosky (1999).
Note 2 Former subgenus of Bazarella Vaillant, 1960, raised to generic level by Ježek (2001).
Note 3 Source of changed placement from Telmatoscopini to Psychodini still needs to be added.
Note 4 Placement in subgenus Apsycha following Boumans (2011).
Note 5 Treated as subgenus of Psychoda following Boumans (2011).
Note 6 Year of description 1998 as used by Wagner & Beuk (2002a) corrected to 1893 (see Bouwmans, 2011).
Note 7 The synonymy was already established by Withers (1988) but who neglected to apply the rules of priority.
Note 8 According to Boumans (2011) zetterstedti resembles satchelli very closely and might even prove to be synonymous.
Note 9 Spelling of species crassipennis as used by Wagner & Beuk (2002a) corrected to crassipenis (see Bouwmans, 2011).
Note 10 Placement in subgenus Psychomora following Boumans (2011).
Note 11 Material examined: OVERIJSSEL: Vasse (Hazelbekke, 1 [m]: 16-18.v.1998, leg. B. van Aartsen MT [NHMM ALC]).
Note 12 Use of genus author Ježek, 1983 as used by Wagner & Beuk(2002a corrected to Enderlein, 1937 (see Bouwmans, 2009a).
Note 13 Nomenclatorial issues surrounding Telmatoscopus and Seoda were discussed by Kvifte (2014).
Note 14 Listed for the Netherlands by Ježek et al. (2012: 122) in the distribution of the species but the record for the Netherlands could not be traced back to any of the references given.
Note 15 After earlier records this species was deleted by De Meijere (1935: 225) and not included in De Meijere (1939b).
