Caryomyia inclinata Gagne, new species

Hosts: Carya laciniosa, tomentosa, ovata

Gall (Figs. 145-146): Occasional, locally common but not east of Appalachian Mts, on Eucarya hickories; on lower leaf surface, on veins; length from center of base to tip 3.3-7.0 mm, leaning, irregularly conical, base prolonged and irregularly lobed opposite direction of incline, the apex with short or long taper, digitate when long; sparsely covered with short, white hair not obscuring green, red, to brown surface; base at center flat or tapered to short-conical pedicel; larval chamber basal, green, with longitudinal ridges, remaining gall tissue woody. Galls are most like those of C. ansericollum, but in that species the base is not conspicuously flattened and outspread to one side opposite the direction of the cone.

Affinities. — Galls of a group of five species are conical, woody, and have more or less digitate apices, but are still distinct in shape and vestiture.

Biological notes. — Between June and beginning August in eastern West Virginia, young and full-grown galls can be found, containing first and second instars, respectively. By the first week of August galls contain either second or third instars. Pupae emerge through the side of the gall near the base.
