Moved from Psylla. There are photos of this species in The Greenland Entomofauna: An Identification Manual of Insects, Spiders and their Allies (2015), including an adult male/female, as well as of the individual genitalia / head/ wing; illustrations may also be found in Ossiannilsson's The Psylloidea (Homoptera) of Fennoscandia and Denmark (1992). Note especially the shape of the male genitalia; compare to P. betulae which has markedly different male genitalia (also illustrated by Ossiannilsson), and P. galeaformis which differs slightly in this regard (compare to illustrations and descriptions in Tuthill (1943) and Patch (1911)).

According to Hodkinson (1978) the species is common on dwarf birch throughout Alaska, and a description of the species is given in Ossiannilsson (1970). Full references cited on new guide page.

Moved from Psyllidae.

leaning towards the latter. Both species are extremely similar in the characters of the male and female genitalia as well as the wing venation. Do you have any photos that would indicate the length of the antennae (relative to the head width?) This is the character Hodkinson uses to separate the two species in his key; host plant info or size could also be enough for ID.
