Taxonomic note.

After Lengersdorf (1930a: 52) and Tuomikoski (1960: 145) Sciara testacea Zetterstedt, described in Zetterstedt (1838: 826), does not belong to the Sciaridae , but to the Diadocidiidae [= Diadocidia testacea (Zetterstedt, 1938)]. Zetterstedt (1851: 3763) later describes another ' Sciara testacea ' [preocc.; not Sciara testacea Zetterstedt, 1838], which without doubt belongs to the Sciaridae and was renamed by Zetterstedt himself as Sciara rufescens [see Zetterstedt (1852: 4545)]. Siebke (1877: 212) used the name ' Sciara testacea Zetterstedt’ in connection with Zetterstedt’s original description in volume ‘X’ of ' Diptera scandinaviae disposita et descripta’ ( Zetterstedt 1851). For that reason the citation by Siebke (1877) and the Norwegian record on page 212 is preliminarily included here.

In the here presented checklist of Norwegian Sciaridae , Bradysia vagans (Winnertz, 1868) is missing, with its synonyms B. angustipennis Frey, 1948 [preocc.], B. callicera Frey, 1948 and B. richardi Gerbachevskaja, 1986. This is a very common species throughout Europe. It is dark brown, with rather broad wings and unicoloured dark-brown antennae, but is not distinguishable by the male genitalia from the reddish-yellow Bradysia rufescens (Zetterstedt). It is possible, that there are some misidentified specimens of Bradysia vagans (Winnertz) among the records of ' Bradysia rufescens ', published before Tuomikoski (1960).

Ecological note.

In the grass in humid places; in botanical gardens. Phenology: Jun.-Aug.
