Pontania consors

Type locality. — Plattsburgh, N.Y.

Host plant. — Salix humilis as identified by G. Argus (not Salix sericea as reported by Dyar).

Notes. — This is a valid species, Pontania (Eupontania) consors Dyar. Dyar described the species as follows: "Galls found with the preceding on S. sericea, but gregarious, hairy and spherical. Near the base of the leaf, three or two together, rarely but one, exceeding the margin often by half the diameter of the gall; not evenly divided by the leaf, about one third or a little more above, two thirds below; pale greenish, often heavily marked and mottled with red above, paler below, rarely uniformly pale. Strongly silky hairy like the leaves below, less hairy or even smooth above; size 8.5— 8.5—7 mm or as small as 5 mm in diameter." The host plant was misidentified by Dyar. The remnants of the leaf were identified by G. Argus, as in the preceding case (P. borealis), as Salix humilis. A. G. Zinovjev and H. Goulet collected galls of P. consors at Lake Jean Venne, Masham Co., Quebec, Canada (about 50 km N of Ottawa) in the fall of 1995 on Salix humilis (host-plant determined by G. Argus).
