Genus Sympherobius Banks, 1904

Type species. Hemerobius amiculus Fitch, 1855 , by monotypy.

Diagnosis. Separated from other hemerobiid genera by the following combination of characters: crossveins 2sc-r, 4r-m, 4im, 4m-cu absent in forewing; outer gradate series of crossveins absent in hind wing.

Species included. More than 50 extant species, distributed nearly worldwide, except Australia and tropical regions of Africa and Asia ( Tjeder 1961; Oswald 1988). Fossil records include Sympherobius completus sp. n. from Eocene Baltic amber, and Sympherobius sp. from Miocene Dominican amber ( Engel & Grimaldi 2007).

Remarks. Although characters of the male genitalia are not known in this species (this only known specimen is female), we confidently assign it to the genus Sympherobius . This is evident from characters such as size, the stylus borne on the ninth gonocoxites, strongly swollen tibiae, and wing venation that is entirely concordant with that of this genus.
