Summary:Key to Gnypeta species occurring in Canada, Alaska and Greenland 1. Basal article of metatarsus longer than two following articles combined.2 – Basal article of metatarsus at most as long as two following articles combined (Fig. 1).3 2. Antennal articles 8-10 strongly transverse (Figs 27 a, b); median lobe of aedeagus with narrowly triangular apical part in lateral view (Fig. 91), and bulbus with two lateral projections in dorsal view (Fig. 92); spermatheca with capsule pitcher-shaped (Fig. 96); female sternite 8 rounded apically (Fig. 98). G. brevicornis Casey – Antennal articles 8-10 quadrate or slightly elongate (Figs 32 a, b); median lobe of aedeagus with broadly triangular apical part in lateral view (Fig. 130); spermatheca C-shaped, capsule mushroom-formed (Fig. 136); female sternite 8 emarginate apically (Fig. 138). G. uteana (Casey) 3. Body broad and robust (Fig. 8), pronotum at base about as broad as elytra (Fig. 8), abdomen swollen medially and at base as broad as elytra (Fig. 8); median lobe of aedeagus and spermatheca as illustrated (Figs 83, 84, 88). G. groenlandica Lohse – Body narrow and less robust (Figs 3, 5, 6, 9, 14, 15), pronotum at base narrower than elytra, abdomen subparallel and at base narrower than elytra (Figs 3, 7, 9-15); genitalia differently shaped.4 4. Elytra at suture approximately as long as pronotum (Figs 3, 6, 7, 10, 15-19). 5 – Elytra at suture distinctly longer than pronotum (Figs 4, 5, 11-13, 20). 13 5. Antennal articles 7-10 strongly transverse (Figs 21 a, b); median lobe of aedeagus and spermatheca as illustrated (Figs 39, 40, 41, 45). G. ashei sp. nov. – Antennal articles 7-10 elongate, subquadrate or slightly transverse (Figs 23-25 a, b, 28 a, b, 31 b, 33-37 a, b); genitalia differently shaped (Figs 75, 76, 80, 99-101, 105, 139-141, 145, 148, 149, 153, 156, 157, 161, 164, 165, 169, 172-174, 178).6 6. Antennal articles 7-10 slightly transverse (Figs 24 a, b, 25 a, b, 33 a, b); female sternite 8 without deep median emargination (Figs 74, 82, 147). 7 – Antennal articles ...
