We present and illustrate some diagnostic characters in addition to those provided in the original description.

Diagnosis

Head, dorsal view 3 as wide as long; with wrinkled reticulate sculpture ( Fig. 1C). Antennae with 15 antennomeres ( Fig. 1E): Relative lengths of antennal segments as: 10:7:30:16:16:16:16:15:14:14:13:13:12:10:10; F1 1.8 as long as F2, flattened ventrally and slightly enlarged apically. Placodeal sensillae visible in all flagellomeres. Notauli indistinct, obscured by coarse rugose reticulate sculpture of mesoscutum. F1 Scutellar foveae 0.4 as long as mesoscutellum; rounded, with defined margins, medially not well separated by a carina; with some strong transversal carinae, the intervals smooth and shining. Mesoscutellum strongly and widely emarginated posteriorly, V shaped in dorsal view ( Fig. 1D); the posteromedial impression deeply and widely extended anteriorly to reach near posterior margins of scutellar foveae. In lateral view with sharp horn projection. Metascutellum reticulate rugose; metanotal trough smooth and pubescent. Median propodeal area coarsely and irregularly carinate, and pubescent; lateral propodeal carinae distinct, subparallel ( Fig. 1I). Nucha smooth medially, laterally carinate. Forewing ( Fig. 13A) heavily infuscate, with a clear cross band from apical area of radial cell which is extended widening below the radial cell, crossing the Medial vein, but not reaching posterior margin of wing. Radial cell 3.7 as long as wide; veins being visible, R1 and radius not quite reaching anterior margin of wing; Rs1 projected into the radial cell; Rs2 slightly curved.

Distribution: Oaxaca, Sierra Juarez

Host: Quercus ocoteifolia , a synonym of Q. laurina

Gall. A spongy oak apple similar to that of the American A. confluentus (Harris) . More or less spherical, thinshelled, spongy interior dense though soft, larvae central or nearer the base of the gall, galls up to 48 mm in diameter, detachable, on twigs.

Biology

Bisexual; galls mature by February, and adults emerge between February and April
