Pteronidea parviserrata Lindqvist, 1944b: 23–24 .

Amauronematus subpolaris Lindqvist, 1949: 71–72 . Holotype not found in MZH.Type locality: Finland, Inari Lapland, Utsjoki, Outakoski. Synonymy by Lindqvist (1959a).

Diagnosis

Externally, females are most similar to E. leucopyga , E. leptostigma , E. sulciceps , E. sordidiapex , E. polepso sp. nov., and E. polaris . The overall shape of the lancet (gradually broadening from tip to base) and shape of serrulae (very elongate and flat) distinguishes E. parviserrata from these species. Serrulae of E. fuscomaculata are quite similar to E. parviserrata , but females of this species have antennae usually as long as costa + pterostigma while antennae are about as long as costa in E. parviserrata . Penis valves of E. parviserrata do not seem to be clearly distinguishable from E. leucopyga , E. leptostigma , E. polaris , E. sulciceps , and E. polepso . Head can be like in “ Amauronematus ”.

Female

Head extensively or slightly pale around eyes; labrum and clypeus pale; supraclypeal area black (usually?); thorax black; pronotum and tegula pale; pterostigma pale; metafemur and metatibia pale; hind tarsus pale or brown; abdomen nearly completely black (usually?); mesepisternum smooth or slightly matt.

Male

Head slightly pale around eyes to nearly completely black; labrum pale; clypeus extensively or slightly pale; supraclypeal area black (usually?); thorax black; pronotum black to extensively pale; tegula pale; pterostigma pale; metafemur pale or basally black; metatibia pale; hind tarsus pale or brown; abdomen dorsally nearly completely black, ventrally mostly black to slightly pale; sternum 9 pale.
