Diagnosis
Lower face with median part dark reddish-brown, pale area reaching to level of middle of toruli (Figs 573, 574); fore wing with four setae on dorsal surface of submarginal vein and admarginal setae in three rows; legs yellowish-brown (Fig. 572); petiole 1.0× as long as wide; gaster with anterior ½ yellowish-white with dark brown lateral margins, posterior ½ dark brown (Figs 575, 576); male antenna with scape slightly expanded and widest above the middle, 3.3× as long as wide (Fig. 578).
Description
Female. Length of body 2.6 mm. Antenna with scape and pedicel yellowish-brown, flagellomere 1 yellowish-brown with infuscations dorsally, 2 dark brown with base yellowish-brown, 3–6 dark brown (Fig. 577). Mandibles and palpi yellowish-white. Head black and shiny, lower face with median part dark reddish-brown, pale area reaching to level of middle of toruli, with parts between pale area and eyes black (Fig. 573). Frons close to eyes with one row of setae (Fig. 590). Vertex with very weak reticulation (Fig. 591). Occipital margin rounded (Fig. 591).
Mesosoma black and shiny (Fig. 572). Each sidelobe of mesoscutum with 13 setae. Scutellum 0.9× as long as wide; with very weak engraved reticulation, posterior margin smooth (Fig. 592). Dorsellum anteriorly with a groove that is divided by longitudinal carinae (Fig. 785), groove medially 0.4× as long as length of dorsellum. Propodeum smooth (Fig. 785); anteromedially with a triangular cup that has posterior part strongly raised; propodeal callus with ten setae. Legs yellowish-brown (Fig. 572). Fore wing: submarginal vein with four setae; costal cell on ventral surface with three rows of setae in basal ½, two rows in apical ½, and margin with eight setae close to marginal vein; with 36 admarginal setae, in three rows.
Gaster with anterior ½ yellowish-white with dark brown lateral margins, posterior ½ dark brown (Fig. 575).
Ratios. HE/MS/WM = 2.2/1.0/1.2; POL/OOL/POO = 6.3/3.3/1.0; OOL/DO = 1.1; WE/WF/WH/HH = 1.0/2.3/4.3/3.0; WH/WT = 1.1; PM/ST = 1.6; TS1/TS2/LT/LT1/LT2/LT3/LT4 = 3.7/2.0/5.5/1.9/1.5/1.0/1.5; LP/WP = 1.0; MM/LG = 0.9.
Male. Length of body 1.6 mm. Scape slightly expanded and widest above the middle (Fig. 578), sensory pores confined to apicoventral ¾, sensory area pale as scape. Otherwise similar to female except shorter gaster.
Ratios. LC/WS = 3.3; MM/LG = 1.3.
Hosts and biology
Feeding on penultimate instar larva of Cyclophora Janzen14 (Geometridae) feeding on Siparuna thecophora (Siparunaceae), parasitoid cocoons stuck to dead larva and substrate.
Distribution
Costa Rica (Alajuela and Guanacaste Provinces).
Etymology
This species is named after Victoria G. Pook, in recognition of her contribution to the understanding of ACG Hymenoptera taxonomy.
Remarks
Euplectrus victoriapookae and Euplectrus davesmithi have the same barcode (Fig. 35, Suppl. material 1), but as they are morphologically distinct and their hosts are very different we treat them as separate species.

![Figure 35. Interspecific variation of DNA barcodes among species of ACG Euplectrus displayed using the Neighbor-Joining method (Saitou and Nei 1987[1]) with distances computed using the Kimura 2-parameter method (Kimura 1980[2]) conducted in MEGA6 (Tamura et al 2013[3]). When there was more than one sequence available for each species, the representative sequence was selected based on quality (longest read length with the fewest ambiguities). Line labels are the voucher code|species name|host family|number of barcoded specimens in the ACG database at the time of writing. In the two cases where two species have nearly identical barcodes, morphological differences suggest that each pair indeed contains two species, the veracity of which will be the subject of further research when more samples are available.](/wiki/File:Zookeys-485-e4835-g011.jpg)
