The West Palaearctic species of Fidiobia Ashmead, (Hymenoptera: Platygastroidea)

Parasitoid wasps new to Britain (Hymenoptera: Platygastridae, Eurytomidae, Braconidae & Bethylidae)

“…Fidiobia hispanica Popovici & buhl, 2010Figs 1-3 Fidobia synergorum -o'connor et al, 2004: 14 [not Kieffer, 1921 [misidentification].…”

“…Specimens were identified to genus using the key by Masner & Huggert (1989) and to species with the key by Popovici & buhl (2010). Detailed illustrations are given by Popovici & buhl (2010).…”

“…Detailed illustrations are given by Popovici & buhl (2010). the following notes are provided to improve the diagnosis of the female metasoma given in the original description of this species and to take account of telescoping of the apical gastral tergites, which varies naturally and can also be affected by the preservation techniques used.…”

“…Fidiobia hispanica Popovici & buhl, 2010 (1.4 ±0.16) {1.5-1.7}; ratio between length and width of t2 0.8-1.1 (0.9 ±0.1) {1.0}; ratio between length of t2 and length of t1 3.3-6.5 (4.1 ±0.9) {4.8-5.0}; ratio between length of t2 and length of t3 3.1-4.0 (3.6 ±0.3) {2.4}; ratio between maximum and minimum width of t2 1.2-1.5 (1.3 ±0.1) {1.2-1.3}; ratio between length of t3 and length of t4 1-1.5 (1.1 ±0.2) {1.0-1.3}; ratio between maximum and minimum width of t3 1.1-1.3 (1.2 ±0.1) {1.1}; ratio between maximum and minimum width of t4 1.1-1.6 (1.2 ±0.1) {1.1-1.3}; t6 triangular, ratio between length of t6 and t5 1.7-2.8 (2.1 ±0.4) {1.3-1.5}. (2004, as F. synergorum) and from Spain and ireland by Popovici & buhl (2010).…”

“…these wasps are endoparasitoids of beetle eggs, and consequently are very small, typically 0.6-1.3 mm, and rarely collected (Popovici & buhl 2010). Fidiobia hispanica was previously reared from the galls of Andricus lignicola by o 'connor et al (2004), although the host remains were not located, and the host identity not confirmed.…”
