Head black and shiny, lower face medially yellowish-brown, pale area reaching to outer lateral margins of toruli, with parts between pale area and eyes black (Fig. 129), vertex dark brown. Frons close to eyes with one sparse row of setae (Fig. 135). Vertex smooth (Fig. 136). Occipital margin with a weak carina behind ocellar triangle (Fig. 136).

Mesosoma black and shiny (Fig. 128). Each sidelobe of mesoscutum with seven setae. Scutellum 0.8 × as long as wide; with very weak engraved reticulation, partly smooth (Fig. 137). Dorsellum along anterior margin with a groove that is divided by longitudinal carinae (Fig. 749), groove medially 0.2 × as long as length of dorsellum, median posterior margin of dorsellum without spines. Propodeum smooth (Fig. 749); anteromedially with a short and wide semicircular cup; propodeal callus with eight setae. Legs yellowish-white (Fig. 128).

Ratios. HE/MS/WM = 1.8/1.0/1.1; POL/OOL/POO = 3.7/1.8/1.0; OOL/DO = 1.3; WE/WF/WH/HH = 1.0/2.6/4.4/3.3; WH/WT = 1.1; PM/ST = 2.0; TS1/TS2/LT/LT1/LT2/LT3/LT4 = 6.3/2.8/7.7/2.3/1.7/1.0/2.0; LP/WP = 1.0; MM/LG = 0.9.

Male. Unknown.

Hosts and biology.

Feeding on second instar larva of Ceromacra Poole02 ( Erebidae ) feeding on Guatteria diospyroides ( Annonaceae ), parasitoid cocoons stuck to leaf substrate.

Distribution.

Costa Rica (Guanacaste Province).

Etymology.

This species is named after Dave R. Smith, in recognition of his contribution to the understanding of ACG Hymenoptera taxonomy.

Remarks.

Euplectrus davesmithi and Euplectrus victoriapookae 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.
