( Figs 7cView FIGURE 7, 8cView FIGURE 8, 9cView FIGURE 9)

Aphidius (Monoctonus) caricis Haliday 1833: 261  , 488.

Material examined. Canada, British Columbia, Gulf Islands National Park Reserve , 23 VII 2012, 2 females, 1 male  ; Langley, James Kennedy Elementary , 2 X 2015, 1 male  ; Victoria, Pacific Forestry Centre , 11 VIII 2014, 1 female  .

Female. Head. Eyes oval, medium sized, sparsely setose. Malar space equal to 0.2 of longitudinal eye diameter. Tentorial index 0.3. Clypeus oval with 7 setae. Maxillary palps with four palpomeres, labial palps with two palpomeres. Antenna with 13 antennomeres, filiform, setae on flagellomeres semierect, subequal to half of flagellomere diameter. Flagellomere 1 (F1) about 3.6 (3.3–3.7)× as long as wide, without longitudinal placodes. F2 about 3 (2.6–3.3)× as long as wide, without longitudinal placodes. F3, F4 and F5 with 1–3, 1 and 1–2 longitudinal placodes, respectively. F1 length equal to F2.

Mesosoma. Notaulices incomplete, visible in anterior third of mesoscutum. Dorsal surface of mesoscutum sparsely setose. Head width/mesoscutum width ratio 1.5. Propodeum areolated, with narrow central pentagonal areola ( Fig. 7cView FIGURE 7).

Fore wing ( Fig. 8cView FIGURE 8). Wing length 1.4 mm, width 0.5 mm. Stigma narrow, about 7.6 (7.3–7.8)× as long as wide and about 3.2 (3–3.4)× as long as distal abscissa of R1. Vein m-cu visible only in first third, vein 2RS not visible. Veins r and  3RS distinct, 3RS sometimes colourless.

Metasoma. Petiole 2× as long as wide at spiracles. Dorsal disc of petiole moderatelly rugose, with 4–5 long setae on each side. Ovipositor sheath ploughshare shaped. Ovipositor sheath length/width ratio 3 ( Fig. 9cView FIGURE 9).

Colour. Head brown, eyes black, mouthparts light brown. Scapus, pedicel, F1, and F2 yellow, remainder of antenna brown. Mesonotum, propodeum and legs brown. Wings hyaline with brown venation. Petiole and rest of metasoma brown, ovipositor sheath light brown to brown. Body length 1.7 mm.

Male. Head. Eyes oval, medium sized, sparsely setose. Malar space equal to 0.2 of longitudinal eye diameter. Tentorial index 0.4. Clypeus oval with 6 setae. Maxillary palps with four palpomeres, labial palps with two palpomeres. Antenna with 16–17 antennomeres, filiform, setae on flagellomeres semierect, subequal to half of flagellomere diameter. Flagellomere 1 (F1) 2.6× as long as wide, with 4 longitudinal placodes. F2 2.2× as long as wide, with 4 longitudinal placodes. F3, F4 and F5 all with 6 longitudinal placodes. F1 length equal to F2.

Mesosoma. Notaulices incomplete, visible only in anterior part of mesoscutum. Dorsal surface of mesoscutum sparsely setose. Head width/mesoscutum width ratio 1.3. Propodeum areolated, with narrow central pentagonal areola.

Fore wing. Wing length 1.7 mm, width 0.6 mm. Stigma narrow, about 8.4 (7.9–8.9)× as long as wide and about 2.6 (2.5–2.7)× as long as distal abscissa of R1. Vein m-cu visible in first third, second third colourless, last third ef- faced. 2RS absent. Veins r and  3RS distinct.

Metasoma. Petiole 1.8× as long as wide at spiracles. Dorsal disc of petiole moderately rugose, with 3–4 long setae on each side.

Colour. Head and antenna brown, mouthparts light brown. Mesonotum brown, propodeum and legs brown. Wings hyaline with brown venation. Petiole and rest of metasoma brown. Body length 1.7 mm.
