Neuroterus acrotrichias (agamic)

Neuroterus acrotrichias Pujade-Villar n. sp. (Figs. 1-4)

Galls (Fig. 3)

Located on the underside of the leaves in large numbers, between the secondary or tertiary veins, rarely on top of them. They are strongly attached to the leaf surface without producing a sinking of the leaf at the point of insertion. They are globular with a flat base, brown on the side and light in the apical zone, with a whitish apical pubescent tuft.. The surface is shiny and alutaceous, sometimes with some weak longitudinal carinae.
The diameter is 1.5-1.6 mm and the height is 1.2-1.3 mm. The larval chamber is located in the lower part of the gall parallel to the leaf (1.2 × 0.5 mm); above it there is a hard tissue that protects the larval chamber above the gall (1.2 × 0.5 mm).
