Abstract
A new genus of dark-winged fungus gnats, Linana Shah & Huang gen. nov. is described from China, with two newly described species: Linana primaria Shah & Huang gen. et sp. nov. as a type species, and Linana confusa Shah & Huang gen. et sp. nov. Morphologically, this genus combines the characters of different clades, by having long and bottleneck-shaped flagellomeres, an undifferentiated tibial organ and non-setose posterior wing veins, but unique male genitalia. DNA barcode data (COI) further support its genetic distinctiveness.
