Phylloxera spinuloides Pergande

Galls on petioles or at bases of main veins of leaflets, of an undetermined Carya species in Florida, USA, were globular (diam. 5-15 mm), with a dense covering of long fleshy filamentous outgrowths; usually encircling the petiole and causing it to bend or curve. Colour uniformly greenish yellow, or brownish yellow on one side. Galls opened in late March, releasing alatae (BL 0.6-1.8 mm, with brownish wings and orange abdomen). Life cycle is unknown, although the early departure of alatae suggests host alternation.

Petiole or twig galls
Globular, densely covered with long, fleshy filaments, diameter 5 to 15 mm.

Phylloxera spinuloida Pergande, n. sp.

The galls of this species, as already remarked, are very similar and closely related to those of spinosa, for which, without comparison of the migratory females, they might easily be mistaken. They are, as a rule, more regularly globular, or but slightly conical, covered with numerous irregular, more or less radiating, low ridges, which are rather plentifully provided with irregular, long, fuzzy, fleshy spines or filaments. They grow generally upon the petiole of the leaves, which they often almost completely encircle, causing, at 'the point of junction with the petiole, a curve or bend. They also occur on the midrib of the leaves. When mature each gall bursts at the apex in a more or less irregular opening. The diameter of those examined varied from 5-15 mm. The color appears to be quite uniformly greenish-yellow, or brownish-yellow on one side.

Phylloxera spinuloides

Globular and densely covered in long slender spines, greenish-yellow or brownish-yellow, and diameter 5.0–15.0 mm; occurs on petioles or along midvein of leaves; opening slit-like or irregular.
