Diagnosis.

On the basis of the number of maxillary (three) and labial (two) palpomeres, number of antennal segments, and possession of an elongate pterostigma, the new species is morphologically related to A. matricariae . However, it differs clearly from A. matricariae in having a very elongate fore wing pterostigma (fore wing pterostigma length/width ratio of 4.96-5.46 in Aphidius longistigmus sp. nov., vs. 3.50-4.00 in A. matricariae ) and shorter flagellomere 1 (F1 length/width ratio of 2.11-2.52 in Aphidius longistigmus sp. nov., vs. 2.50-3.00 in A. matricariae ).

Description.

Female. Length of body about 1.85 mm (Fig. 3A View Figure 3 ). Length of fore wing 1.45 mm (Fig. 3B View Figure 3 ).

Head. Tentorial index 0.39-0.50 (Fig. 3D View Figure 3 ). Malar space 0.26-0.30 times longitudinal eye diameter. Antenna 13-15-segmented (Fig. 3C View Figure 3 ). F1 slightly shorter than F2. F1 and F2 2.11-2.52 and 1.93-2.28 times as long as their width at the middle, respectively. F1 with 2-3 and F2 with 3-4 longitudinal placodes. Maxillary palp with three palpomeres, labial palp with two palpomeres. Ratio of eye to temple in dorsal view 0.98-1.13. Face width/height ratio 1.43-1.51 (Fig. 3D View Figure 3 ).

Mesosoma. Propodeum with clearly defined central areola, areola length/ width ratio 1.00 (Fig. 3E View Figure 3 ). Pterostigma 4.96-5.46 times as long as wide. Ratio of pterostigma length to R1 vein (=metacarpus) length 1.00-1.34 (Fig. 3B View Figure 3 ).

Metasoma. Petiole 3.09-3.29 times as long as wide at spiracles (Fig. 3F, G View Figure 3 ), with about 10 curved costulae in anterolateral area (Fig. 3G View Figure 3 ). Petiole with prominent dorsal carina (Fig. 3F View Figure 3 ).

Colour. Antenna dark-brown; scape, pedicel, and flagellomere 1 yellowish-brown, partly dark-brown. Head black. Face with clypeus dark-brown, mouth parts yellowish-brown. Dorsal side of mesoscutum and metasoma dark-brown, except for propodeum with petiole. Legs yellowish-brown with dark apices.

Etymology.

The name of the new species refers to the very long fore wing pterostigma.
