Material.

Holotype a female labeled "COSTA RICA: Guanacaste, ACG, Sector Pitilla, Amonias, 20.ix.2007, P. Rios, ex Letis mycerina eating Inga oerstediana , sibling of wasp DHJPAR0028972, 07-SRNP-33368" (BMNH).

Diagnosis.

Lower face with median part yellowish-brown, pale part reaching slightly outside of level of outer lateral margin of toruli (Fig. 333); fore and mid coxae yellowish-white, remaining parts of fore and mid legs and entire hind leg yellowish-brown (Fig. 332); scutellum 0.8 × as long as wide with slightly elongate meshes, very posteromedian part with transverse meshes (Fig. 341); dorsellum without a groove or foveae along anterior margin (Fig. 782); propodeum anteromedially with a transverse triangular cup, median carina on propodeum wide (Fig. 782); petiole 1.0 × as long as wide; gaster dark brown, anterior ½ with a large yellowish-white spot (Fig. 334), and with tergites 5-6 reddish-brown posteromedially.

Description.

Female. Length of body 2.3 mm. Antenna with scape yellowish-white in basal ½ and yellowish-brown in apical ½, pedicel yellowish-brown, flagellomeres 1-4 dark brown with ventral part yellowish-brown, 5-6 dark brown (Fig. 335). Mandibles and palpi white. Head black and shiny, lower face with median part yellowish-brown, pale part reaching slightly outside of level of outer lateral margin of toruli, with parts between pale area and eyes black (Fig. 333). Frons close to eyes with one irregular row of setae (Fig. 339). Vertex with very weak reticulation (Fig. 340). Occipital margin with a weak carina behind ocellar triangle (Fig. 340).

Mesosoma black and shiny (Fig. 332). Each sidelobe of mesoscutum with 12 setae. Scutellum 0.8 × as long as wide; with very weak reticulation, meshes slightly elongate (Fig. 341). Dorsellum without a groove or foveae along anterior margin (Fig. 782). Propodeum smooth (Fig. 782); anteromedially with a strongly transverse triangular cup that is 0.3 × as long as wide; propodeal callus with nine setae. Legs (Fig. 332): fore and mid coxa yellowish-white, remaining parts of fore and mid legs and entire hind leg yellowish-brown. Fore wing: costal cell with two irregular and sparse rows of setae on ventral surface, and margin with three setae close to marginal vein; with 21 admarginal setae, partly in two rows.

Gaster dark brown, anterior ½ with a large yellowish-white spot (Fig. 334), and with tergites 5-6 reddish-brown posteromedially.

Ratios. HE/MS/WM = 2.6/1.0/1.4; POL/OOL/POO = 5.0/3.0/1.0; OOL/DO = 1.4; WE/WF/WH/HH = 1.0/2.0/3.7/2.8; WH/WT = 1.0; PM/ST = 1.9; TS1/TS2/LT/LT1/LT2/LT3/LT4 = 4.4/2.2/8.0/2.4/1.9/1.0/1.9; LP/WP = 1.0; MM/LG = 1.3.

Male. Unknown.

Hosts and biology.

Feeding on second instar larva of Letis mycerina ( Erebidae ) feeding on Inga oerstediana ( Fabaceae ), parasitoid cocoons stuck to dead larva and substrate.

Distribution.

Costa Rica (Guanacaste Province).

Etymology.

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

Remarks.

The barcode from the single available specimen from this sample (DHJPAR0028972) is very similar to the barcode of DHJPAR0023280 (Suppl. material 1). Specimens from DHJPAR0023280 are included under the description of Euplectrus daveroubiki . Specimens from DHJPAR0028972 are morphologically distinct from those of DHJPAR0023280, and also have a very different host. Therefore we prefer to treat these two samples as different species. See also remarks under Euplectrus daveroubiki .
