( Figs 29–33 View Figs 29–33 )
Type locality. Serbia, Kovilovo, 44°54′48.87″ N, 20°25′43.31″ E.
Type specimens. HOLOTYPE: ♀, glued, deposited in UB. Original label: 14.vi.2010, alfalfa field, complex landscape, Kovilovo, Serbia, Alloxysta brevis (Thomson) , ♀, det.A. Stojanović, 2012.The holotype was collected from mixed colony of Therioaphis trifolii and Acyrthosiphon pisum (Harris, 1776) on Medicago sativa . PARATYPES: 1 JJ 7 ♀♀. SERBIA: Praon exsoletum – Therioaphis trifolii on Medicago sativa, Živkovac-Site 2, 3.vi.2012: 1 ♀; Same data, Umčari-Kotlova, 9.vi.2012: 1 J 1 ♀; same data, Osipaonica, 11.vi.2012: 1 ♀; Aphidius sp. – Sitobion avenae on Triticum aestivum, Umčari-Donji Kraj , 12.vi.2012: 4 ♀♀. [All material deposited in UB].
Diagnosis. Alloxysta kovilovica sp. nov. is characterized by closed radial cell ( Figs 29, 31 View Figs 29–33 ), while pronotal ( Fig. 32 View Figs 29–33 ) and propodeal ( Fig. 33 View Figs 29–33 ) carinae are absent. It is similar to A. aperta ( Hartig, 1841) but they can be easily differentiated by the relation between flagellomeres: F1 longer than F2 and F 3 in A. kovilovica sp. nov. while F1–F3 subequal in length in A. aperta .
Description. Female. Head. Transversely ovate, smooth and shiny, slightly wider than its height in frontal view. Few setae present below, and between the toruli. The area above the toruli and vertex with few scattered setae, face with numerous setae. Transfacial line 1.0 times height of compound eyes. Malar space 0.4 times height of compound eyes.
Antenna. 13-segmented, filiform. All antennomeres with sparse setae. F1–F2 smooth and thinner than remaining flagellomeres; F3–F11 club-shaped, with rhinaria. Antennal formula: 3.5 (1.5); 4.0 (1.0); 3.5 (1.1); 3.5 (1.2); 4.0 (1.4) ( Fig. 30 View Figs 29–33 ).
Mesosoma. Pronotum covered with scattered setae, without carinae ( Fig. 32 View Figs 29–33 ). Mesoscutum smooth and shiny, round in dorsal view with few scattered setae, and two lines of setae on lateral sides. Scutellum smooth and shiny with scattered setae that are more abundant on apex of scutellum. Height of mesopleural triangle along anterior margin 1.4 times the height of mesopleuron. Propodeum covered with numerous setae; without carinae ( Fig. 33 View Figs 29–33 ).
Forewing. Longer than body, 1.4 times as long as mesosoma and metasoma together; densely pubescent; marginal setae present ( Fig. 29 View Figs 29–33 ). Radial cell closed, 2.5 times as long as wide ( Fig. 31 View Figs 29–33 ). R1 short and slightly curved upward; Rs considerably elongated, slightly curved.
Metasoma. Proximal part with incomplete ring of setae, glabrous centrally, laterally broader. Remainder of metasoma smooth, shiny with clearly visible terga.
Body length. Female: 1.1 mm.
Coloration. Head, mesosoma and metasoma yellowish brown.Antennae yellow, darkening towards tip. Legs yellow. Veins yellowish brown.
Male. With the same features as female.
Etymology. The new species is named after Kovilovo, the suburban settlement of Belgrade; adjective.
Distribution. This species is only known from Serbia.
Remarks. On the basis of extensive sampling in alfalfa and cereal agroecosystems, as well as in surrounding non-crop habitats, it seems that the new species was associated with cereal and alfalfa aphids.
