Cenalox conyssae

Hosts: Nyssa sylvatica

Relationship: Elongate, lower surface, leaf pockets filled with hard lobes, along leaf veins. The galls cause protrusions on upper leaf surfaces. This mite is an inquiline in leaf margin roll galls caused by Aceria dina; short sections of the long galls contain only white, broad mites, which are this species; it may be inquiline in galls of Cenalox nyssae as well.

Range: OH, WV

[T]wo distinctive species, Cenalox nyssae and C. conyssae also infest túpelo. Specimens were found recently on the underside of the leaves in galls along the midribs and veins. The simple distinctions of the two galls concern their form, position, and texture. Those caused by C. nyssae are small, rounded pockets filled with erineum; the galls appear alongside the midrib at angles of lateral veins. <b>The C. conyssae galls are rough, open pockets filled with fleshy lobes, and they appear alongside the veins. Both galls form slight swellings on the upper surface of the leaves.</b>
