Ormyrus wachtli Mayr, 1904.

Material examined.

ex gall Neaylax verbenacus on Salvia verbenaca , Spain, Madrid: Dehesa de Arganda, 09.VI.02 J. L. Nieves leg (n = 1).

Description.

n = 1; Body length: 1.67 mm, width: 0.80 mm. The larva of this species is similar to the larva of Ormyrus diffinis , from which may be distinguissed as follows: body fusiform, wider at the level of segments ABS2-ABS3, tapering progresively towards ANS; anal segment wider tan length; adp absent; integument of the abdominal and thoracic segments blister-like. Head 1.18 as wide as high (Fig. 8E) with blister-like sculpture extended on all the head; antennae situated at mid position in the face; ams situated clearly above the antennae; lateral lobes of labrum almost fused with the medial lobe; ventral margin of medial lobe of labrum straight (Fig. 10C).

Biology.

The larva of Ormyrus wachtli is a solitary ectoparasitoid of larvae of cynipids, inducing galls on fruits of Salvia ( Lamiaceae ). Along the Iberian Peninsula and in southern Europe, the species is associated with galls of Neaylax salviae (Giraud) on Salvia lavandulifolia (Fig. 15L) and Neaylax verbenacus (Nieves-Aldrey) on Salvia verbenaca (Fig. 15J and K) ( Nieves-Aldrey 2001, Nieves-Aldrey and Askew 2002, Askew et al. 2006). The species has a bivoltine life cycle.
