It is similar to A. melanogaster (Hartig, 1840) male but they can be differentiated by the beginning of rhinaria and club: F 2 in A. staryi but F 3 in A. melanogaster ; and the proportion between flagellomeres: F1 longer than pedicel and subequal to F2, F2 longer than F 3 in A. staryi while pedicel-F3 subequal in length in A. melanogaster . Etymology This species is named after Petr Starý, collector of the material, and without whom this material would not have been possible to be studied. Material examined Known only from one male .

All antennomeres covered with sparse setae. F1 smooth and thinner than remaining flagellomeres, F2–F12 with placodeal sensilla and club shaped. Antennal formula: 2.0 (1.2); 2.5 (0.9); 2.5 (1.1); 2.3 (1.1); 2.5 (4.3); 2.5 (1.3), F5–F12 subequal in length, width, and shape ( Fig. 4E ). Female unknown. MESOSOMA . Pronotum covered by disperse setae, being less in the distolateral corners and abundant in the anterior margins, with two small carinae present ( Fig. 4B ). Mesoscutum smooth and shiny, round in dorsal view with few scattered setae. Scutellum smooth and shiny with scattered setae, more abundant on apex of scutellum. Propodeum covered by abundant long pubescence, with protruding plate, this plate has a few setae on first half and curved sides ( Fig. 4D ). FORE WING . Longer than body, 1.4 times as long as mesosoma and metasoma together. Covered with dense pubescence; marginal setae present and very long ( Fig. 4A ). Partially open radial cell, 2.3 times as long as wide. R1 short and curved; Rs long and slightly curved ( Fig. 4A ). METASOMA . Anterior part with an incomplete ring of setae, glabrous at centre, wider laterally. Metasoma smooth and shiny, T3 and T4 clearly distinguished. Distribution Obec Byšice ( Czech Republic ). Host Emerged from Aphis farinose Gmelin, 1790 ( Hemiptera : Aphididae ) via Aphidius salicis Haliday, 1834 ( Braconidae : Aphidiidae ) on Salix L. ( Salicaceae ).
