Sweep sample, Toronto, Ontario, Canada 2013-09-10. I know of nothing like it from temperate North America. It resembles the descriptions of east Asian species like Siphunculina stackelbergi Duda, 1933 and S. nidicola Nartshuk, 1971. Setulae on head and thorax pale. Frontal triangle clearly shorter than frons, mostly shining, with longitudinal median sulcus. Pollinose area around ocelli in an hourglass shape. Ocellar and postocellar setae slightly convergent. Second costal sector about half as long as third.

Chloropidae, Oscinellinae, Siphunculina Rondani, 1856 spec. Atypical in the 1st photo for the genus is the relatively long distance between veins R1 and R2+3. In my database World Chloropidae Online ( https://sdei.senckenberg.de/tschirnhaus-chloropidae/ ), 38 valid species and 10 invalid/synonymous names are presented together with the literature for each taxon and its geograpic Regions of occurrence. Many Siphunculina spp. (eye gnats) are distributed over several continents. Thus, for an identification much literature must be studied, cited in the bibliography https://sdei.senckenberg.de/tschirnhaus-bibliography/. Feed in Siphunculina in the field Name or each of the 48 species names in the field Genus. |
