Aprostocetus (Aprostocetus) rubi Graham, 1987: 319   , fig. 433.

Material studied. 3 ♀, Poland, Włocławek, reared from nearly 20 galls of Lasioptera rubi   on Rubus idaeus   collected in a pine forest on 08.III. 2015, adults obtained a month later; 1 ♀, 1 Ƌ, same collecting site but five galls taken on 19.II. 2016 and adult wasps obtained a month later; all collected and reared by P. Jałoszyński (PJ personal collection).

Description of the male. Body ( Figs 2 View FIGURES 1, 2 , 3– 14 View FIGURES 3 – 7 View FIGURES 8 – 14 ) pigmented as for dark forms of females described by Graham (1987), except distal portion of first gastral tergite and nearly entire basal half of gaster ventrally pale yellowish; antenna with long brownish setae, otherwise yellowish with scape infuscate dorsally and ventrally, pedicel infuscate dorsally, and flagellum infuscate ventrally. Body length 1.75 mm, smaller than all studied females.

Structures of head ( Fig. 9 View FIGURES 8 – 14 ) similar to those previously described for the female ( Graham 1987); measurements: length 0.20 mm, width 0.50 mm, height 0.40 mm, malar space 0.12 mm, longest diameter of compound eye 0.22 mm, POL 0.12 mm, OOL 0.05 mm. Malar sulcus ( Fig. 9 View FIGURES 8 – 14 ) slightly curved. Antenna ( Figs 3 –5 View FIGURES 3 – 7 , 10, 11 View FIGURES 8 – 14 ) nearly filiform, length 1.06 mm (distinctly longer in relation to body than for females); scape 0.8 × shorter than longest diameter of compound eye, ventrally swollen and with conspicuous but short plaque ( Figs 10, 11 View FIGURES 8 – 14 ) located in distal half; pedicel distinctly broadening distally; F 1–4 subequal in width, nearly cylindrical, each with whorl of very long setae; clava long with first clavomere narrowing distally so clava distinctly constricted, second and third clavomeres confluent, and first clavomere with whorl of long setae. Relative lengths of scape: pedicel: F 1: F 2: F 3: F 4: clava (with pedicel as 1) = 2: 1: 1.14: 1.42: 1.42: 1.57: 3.57.

Structures of mesosoma ( Figs 6 View FIGURES 3 – 7 , 12 View FIGURES 8 – 14 ) similar to those of female; measurements: length 0.72 mm, maximum width 0.50 mm; length of pronotum (measured in lateral view) 0.25 mm, length of mesoscutum 0.37 mm, length of scutellum 0.22 mm, length of dorsellum 0.05 mm, length of propodeum (at midline) 0.07 mm. Median area of mesoscutum with faint but discernible median longitudinal line.

Wings ( Fig. 7 View FIGURES 3 – 7 ) hyaline and not different from those of females, fore wing length 1.62 mm, width 0.72 mm; hind wing length 1.25 mm, width 0.25 mm.

Middle leg with tibial spur appearing about as long as basitarsus in studied dry-mounted specimens, but 1.2 × as long as basitarsus in SEM images (Figs 13,14), and covered with spines.

Gaster ( Figs 3 –5 View FIGURES 3 – 7 , 8 View FIGURES 8 – 14 ) only about as long as mesosoma (i.e. shorter in relation to mesosoma than for females) and more slender than for females, in dorsal view suboval; measurements: length 0.82 mm, width 0.32 mm, ratio length/width 2.53.
