Alloxysta slovenica Ferrer-Suay & Pujade-Villar sp. nov.

( Figs 34–38 )

Type locality. Slovenia, Velika planina, 46°18′15.33″ N, 14°38′54.46″ E.

Type specimen. HOLOTYPE: ♀, glued, deposited in UB. Original label: VP3 (handwritten), Alloxysta sp. det. A. Stojanović. 2011. The holotype was reared from unknown primary parasitoid of Brachycaudus cardui (Linnaeus, 1758) on Cirsium eriophorum .

Diagnosis. Alloxysta slovenica sp. nov. is characterized by partially open radial cell, absence of pronotal carinae, and presence of propodeal carinae which are forming a plate. It is similar to A. rufiventris ( Hartig, 1840) but they can be easily differentiated by the proportion between flagellomeres: F1 shorter than pedicel but longer than F2 and F 3 in A. slovenica sp. nov. while pedicel and all F1–F3 are subequal in length in A. rufiventris .

Description. Female. Head. Transversely ovate, smooth and shiny, slightly wider than high in frontal view. Setae present below and between toruli, the area above toruli without setae, vertex with scattered setae, face with numerous setae. Transfacial line 1.0 times height of compound eye. Malar space 0.4 times height of compound eye.

Antenna. 13-segmented, filiform. All antennomeres with sparse setae. F1–F3 smooth and thinner than remaining flagellomeres; F4–F11 club-shaped, with rhinaria. Antennal formula: 3.5 (2.2); 2.5 (1.2); 2.0 (1.3); 1.8 (1.3); 2.5 (1.5) ( Fig. 36 ).

Mesosoma. Pronotum covered with setae, without carinae ( Fig. 38 ). Mesoscutum smooth and shiny, round in dorsal view with few scattered setae, with two lines of setae on both sides. Scutellum smooth and shiny with scattered setae, which are more abundant on apex of scutellum. Height of mesopleural triangle along anterior margin 1.4 times height of mesopleuron. Propodeum covered with numerous setae; with two carinae forming a plate and few setae present only in the upper half ( Fig. 37 ).

Forewing. Longer than body, 1.4 times as long as mesosoma and metasoma together; covered with dense pubescence; marginal setae present ( Fig. 34 ). Radial cell partially open, 2.2 times as long as wide ( Fig. 35 ). R1 short and slightly curved; Rs long, slightly curved.

Metasoma. Proximal part with incomplete ring of setae, glabrous centrally, laterally broader. Rest of metasoma smooth, shiny with clearly visible terga.

Body length. 1.0 mm.

Coloration. Head, mesosoma and metasoma yellowish brown. Scape yellowish brown, pedicel, F1–F3 dark yellow, F4–F11 yellowish brown. Legs yellow. Veins yellowish brown.

Male. Unknown.

Etymology. The new species is named after the country where it was first found; adjective.

Distribution. This species is known only from Slovenia.
