Diagnosis.
In some morphological characters (shape of the first flagellomere and antennae, number of antennal segments, shape of the pterostigma, and number of maxillary and labial palps), Aphidius longicarpus sp. nov. is similar to A. funebris and A. balcanicus . However, it clearly differs from A. balcanicus in having a shorter R1 vein (the R1 vein is subequal to pterostigma length in Aphidius longicarpus sp. nov., while in A. balcanicus the ratio of pterostigma length to R1 vein length is 1.4-2.0). It differs from A. funebris in possessing a more elongate pterostigma (the pterostigma length/width ratio is 4.06 in Aphidius longicarpus sp. nov., vs. 3.0-3.5 in A. funebris ) and a more elongate petiole (the petiole length/width ratio at the spiracle level is about 3.14 in Aphidius longicarpus sp. nov., vs. 2.5-2.9 in A. funebris ). The new species is distinguished from all other congeneric Aphidius species by a combination of the following characters: 16-segmented antennae, short first flagellomere (length/width ratio of about 2.6), and subequal length of the R1 vein and pterostigma.
Description.
Female. Length of body about 2.26 mm (Fig. 2A View Figure 2 ). Length of forewing 2.06 mm (Fig. 2B View Figure 2 ).
Head. Tentorial index 0.53 (Fig. 2D View Figure 2 ). Malar space 0.29 × longitudinal eye diameter. Antenna 16-segmented (Fig. 2C View Figure 2 ). F1 slightly shorter than F2. F1 and F2 2.61 and 3.35 times as long as their width at the middle, respectively. F1 and F2 with three and four longitudinal placodes, respectively. Maxillary palp with four palpomeres, labial palp with three palpomeres. Ratio of eye to temple in dorsal view 1.40. Face width/height ratio 1.25 (Fig. 2D View Figure 2 ).
Mesosoma. Propodeum areolated, areola length/width ratio 2.00 (Fig. 2E View Figure 2 ). Pterostigma 4.06 times as long as wide. Ratio of pterostigma length to R1 vein (=metacarpus) length 1.14 (Fig. 2B View Figure 2 ).
Metasoma. Petiole 3.14 times as long as wide at spiracles (Fig. 2F, G View Figure 2 ), with eight curved costulae in the anterolateral area (Fig. 2G View Figure 2 ). Petiole rugose on dorsal side, with prominent dorsal carina (Fig. 2F View Figure 2 ).
Colour. Antenna black; scape yellowish-brown; pedicel brown to black from base to apex. Head black. Face brown, clypeus with mouthparts yellowish-brown. Dorsal side of mesoscutum and metasoma dark brown, except yellowish brown propodeum and petiole. Legs yellowish-brown with dark apices.
Etymology.
The name of the new species refers to the very long fore wing R1 vein (=metacarpus).
