Amphibolips durangensis Nieves-Aldrey & Maldonado, 2012 . In Nieves-Aldrey et al., 2012: 9–11.

Type material examined. HOLOTYPE. ♀ deposited in MNCN, dissected and mounted on a stub (Cat. nº 2246; Code: 89198). “ MEXICO, Durango, Palmito, N 23º 33’ 49.4” W 105º 51’ 08.8”, 1977 m; Ex Q. scytophylla Liebm. (Fagaceae), (08.vii.2008) x.2008; leg. Y. Maldonado”.

Diagnosis. This species is characterized by completely infuscate forewings with a complete transversal clear band on distal third; absence of notauli; scutellar foveae indistinctly separated medially, bottom of scutellar foveae with longitudinal rugae medially (Fig. 11B). Closely resembles A. castroviejoi by the forewing pattern but differs by the presence of notauli and conspicuous median carina dividing scutellar foveae in A. castroviejoi . The gall of this species closely resembles A. fusus, differs by the elongation of both, peduncle and apical tip, thinner in A. durangensis; surface of galls is crossed by longitudinal ridges in A. durangensis and smooth in A. fusus .

Gall. Galls on buds, fusiform, maximum 43–54 mm in diameter, with elongate thin peduncle and apical tip; outer shell thin, hard, usually smooth with longitudinal ridges; internal spongious soft tissue with central larval chamber, around 5 mm (Nieves-Aldrey et al. 2012: Figs 18C–D).

Host. Quercus scytophylla .

Biology. Only females are known. The mature galls were collected in early July; adults emerged in October.

Distribution. Mexico: Durango State.
