Amphibolips durangensis Nieves-Aldrey & Maldonado

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.
