Re-visiting the Aphidius urticae s. str. group: re-description of Aphidius rubi Starý and A. silvaticus Starý (Hymenoptera: Braconidae: Aphidiinae) Jamhour, Aiman Mitrović, Milana Petrović, Andjeljko Starý, Petr Tomanović, Željko Zootaxa 2016 4178 2 278 288 67LK8 Stary Stary [151,454,151,178] Insecta Braconidae Aphidius Animalia Hymenoptera 6 284 Arthropoda species silvaticus   Diagnosis.For differentiation of  A. silvaticusfrom  A. rubi, see  A. rubidiagnosis above.  Aphidius silvaticusdiffers from  A. urticaein having more longitudinal placodes on F2 (2–3 longitudinal placodes in  A. silvaticus, one placode in  A. urticae) and a higher tentorial index (  A. silvaticusis 0.45–0.55, 0.35–0.40 in  A. urticae). It differs from  A. urticaein its host range pattern, since  A. urticaeis a specialized parasitoid of the stinging nettle aphid (  Microlophium carnosum), while  A. silvaticusparasitizes  Amphorophoraaphid hosts.   Description.Female. Head:Head wider than mesoscutum (the ratio between head width and mesoscutum width is 1.30–1.39). Eyes oval, with sparse setae ( Fig. 5a). Clypeus oval, with 10–16 long setae. Tentorial index (tentoriocular line/intertentorial line) equal to 0.45–0.55. Antennae (18) 19–20-segmented, filiform, reaching about half of metasoma with semierect and adpressed setae shorter than diameter of the segments. F1 ( Fig. 5b) 3.30–3.80 × as long as median width, without longitudinal placodes. F2 ( Fig. 5b) is 3.00–3.50 × as long as median width, with (2) 3 longitudinal placodes. F1 subequal to F2 (F1/F2 = 0.94–1.03) ( Fig. 5b). Maxillary palp with four palpomeres, labial palp with three palpomeres.  Mesosoma:Mesonotum with notaulices distinct in the ascendent part, deep, crenulated, sparsely setaceous, with two rows of setae along the mesonotum. Notaulices effaced on the disc ( Fig. 5c). Propodeum areolated with central pentagonal areola ( Fig. 5d). Upper lateral areolae with 10–13 setae each, and lower lateral areolae with 4–5 setae. The ratio between hind leg tibia length and first tarsomere length is 3.35–3.42, while that between hind leg tibia length and second tarsomere length is 7.45–8.15. The ratio between lengths of the first and second tarsomeres of the hind leg is 2.18–2.45.  Fore wing:Stigma moderately elongate, 3.50–4.00 × as long as wide and 0.91–1.00 × as long as distal abscissa of R1 (= metacarpus). The ratio between length and width of the fore wing is 2.44–2.60.  Metasoma:Petiole elongate, slender, 3.30–3.60 × as long as wide at spiracles ( Fig. 5f), with 10–12 costulae on its anterolateral area and with a short mediodorsal carina that is not clearly defined. Ovipositor sheath slightly concave on its dorsal margin ( Fig. 5g).  Colour:Head black-brown with yellow face, frons, genae, clypeus and mouthparts. Scape yellow, pedicel brown. F1 yellow at the base, and sometimes F2 and F3 also yellow. Remaining part of antennae brown. Mesosoma and metasoma mostly yellow or light brown. Legs yellow with brown apices. Propodeum light brown. Ovipositor sheath black.  Body length: 2.9–3.6 mm.  Male:Antennae 21–22 segmented. F1 2.00–2.10 × as long as wide. F1 and F2 with 6–8 and 7–9 longitudinal placodes, respectively. Stigma about 3.50 × as long as wide, metacarpus subequal to stigma length. Petiole subsquare, about 2.80–2.90 × as long as wide at spiracle level. Body generally darker than female.   Examined material:We re-examined type specimens (for collection details, see Starý, 1962);   Amphorophora ampullataBuckton on  Dryopteris austriaca2♀, Rusava, 20-VII-1963(CZE);   Amphorophora idaei(Börner) on  Rubus idaeus4♀ 5Ƌ, Sint–Truiden, 09-VII-2015(BEL); on  Rubussp. 1♀ 1Ƌ, Sint–Truiden, 16-IX-2014(BEL);   Amphorophora rubi(Kaltenbach) on  Rubus idaeus1Ƌ, Kopaonik, 17-VII-2013(SER); on  Rubussp. 1♀ 2Ƌ, Brestovik, 27-V-2011(SRB); 2♀ 3Ƌ Helsinki 15-28-VII-1963(FIN); 23♀ 15Ƌ, Plitvice–Kozjak, 21-VI-2015(CRO);   Amphorophorasp. on  Dryopterissp. 3♀ 1Ƌ, Divčibare, 05-VIII-1999(SRB); on  Rubussp. 1♀ 1Ƌ Petnica, 18-V-1998(SRB); 2Ƌ, Tara–Derventa, 31-V-1998(SRB); 5♀ 2Ƌ, Tara–Derventa, 20-V-2000(SRB); 4♀ 1Ƌ, Sint–Truiden, 16-IX-2014(BEL),  1♀, Praha–Košíře,  VI-1978(CZE). 1324019980 [585,981,1626,1651] 1978-06 Praha 6 284 1 1 Praha
