Diagnosis.
On the basis of the number of antennal segments and wing venation pattern, the new species is morphologically related to A. matricariae and Aphidius longistigmus sp. nov.. However, it differs clearly from A. matricariae in having a more elongate fore wing pterostigma (the fore wing pterostigma length/width ratio is 4.62-4.79 in Aphidius asiaticus sp. nov., vs. 3.50-4.00 in A. matricariae ) and a shorter flagellomere 1 (The F1 length/width ratio is 2.23-2.49 in Aphidius asiaticus sp. nov., vs. 2.50-3.00 in A. matricariae ). Aphidius asiaticus sp. nov. differs from Aphidius longistigmus sp. nov. in having a less elongate pterostigma (the pterostigma length/width ratio is 4.62-4.79 in A. asiaticus sp. nov., vs. 4.96-5.46 in Aphidius longistigmus sp. nov.). Additionally, A. asiaticus sp. nov. has four maxillary palpomeres (or three when the last one is very long and undivided), while A. longistigmus sp. nov. has three maxillary palpomeres.
Description.
Female. Length of body about 1.85 mm (Fig. 4A View Figure 4 ). Length of fore wing 1.45 mm (Fig. 4B View Figure 4 ).
Head. Tentorial index 0.47-0.50 (Fig. 4D View Figure 4 ). Malar space 0.28-0.31 times longitudinal eye diameter. Antenna 13-15-segmented (Fig. 4C View Figure 4 ), thickened at apex. F1 slightly shorter than F2. F1 and F2 2.23-2.49 and 2.11-2.14 times as long as their width at the middle, respectively. F1 with 0-3 and F2 with 1-3 longitudinal placodes. Maxillary palps with four or three palpomeres (in the latter case, the last palpomere is long and undivided), labial palp with two palpomeres. Ratio of eye to temple in dorsal view ca. 1.00. Face width/ height ratio 1.44-1.54 (Fig. 4D View Figure 4 ).
Mesosoma. Propodeum with clearly defined central areola, areola length/ width ratio 1.18-1.20 (Fig. 4E View Figure 4 ). Pterostigma 4.62-4.79 times as long as wide. Ratio of pterostigma length to R1 vein (metacarpus) length 1.26-1.32 (Fig. 4B View Figure 4 ).
Metasoma. Petiole 3.08-3.12 times as long as wide at spiracles (Fig. 4F, G View Figure 4 ), with about 10 curved costulae in anterolateral area (Fig. 4G View Figure 4 ). Mediodorsal carina of petiole well developed (Fig. 4F View Figure 4 ).
Colour. Antennal scape, pedicel, and flagellomere 1 yellow, flagellomere 2 yellow at the base, remaining parts of antennae yellowish to light-brown. Head black. Face with clypeus dark-brown, mouth parts yellow. Dorsal side of mesoscutum and metasoma dark-brown except for the yellow to light-brown propodeum (propodeum sometimes dark-brown) with yellow petiole. Legs yellow with dark apices.
Etymology.
The name of the new species is derived from its known geographic distribution.
