Treatment

Lathrolestes syringe Reshchikov sp. nov.

Description. Female. Body length 4.0–5.0 mm. Antennal flagellum with 26 articles. Width to length ratio of scapus 0.53. Head narrowed behind the eyes, mat. Maximal length of temple to transverse eye diameter ratio 0.8; minimal length of temple to transverse eye diameter ratio 0.6. Face as wide as longitudinal eye diameter; in profile convex, with bulge. Clypeus separated from face by transverse impression; at apex projecting slightly anteriorly; apical margin of clypeus moderately thick. Clypeal foveae small. Malar space as wide as 0.33 of basal mandible width ( Fig. 53 View FIGURES 53 – 58 a). Occipital carina complete, not interrupted above. Lower mandible tooth longer than upper.

Mesosoma . Notaulus shallow, impressed at base. Lower part of mesopleuron without punctures, mat, meshed. Tarsal claws weakly pectinate ( Fig. 41 View FIGURE 41 – 52. 41 – 50 ). Hind tarsus article length ratio: 8:4:3:2:3. Forewing with areolet petiolate. Second recurrent vein with a single bulla. Nervellus intercepted below middle. Nervulus postfurcal. Propodeal carinae complete ( Fig. 31 View FIGURE 21 – 40. 21 – 30 ). Area superomedia elongate.

Metasoma. Shiny. First metasomal tergum width to length ratio 0.6; with shallow median longitudinal impression; bordered by lateral longitudinal carinae, median longitudinal carina defined at base. Ovipositor straight, without notch, syringe –like, extra heavy at base, not stout dorsally ( Fig. 1 View FIGURES 1 – 20 ).

Color. Face, malar space, temple, base of antenna, tegulae, edges of propleuron, mesopleuron, legs, scutellum, 3d and 8th metasomal tergum, hind part of second and other tergum laterally yellow ( Fig. 53 View FIGURES 53 – 58 b). Remainder black.

Comments. This species differs from the similar L. barroni Reshchikov sp. nov. by ovipositor not stout dorsally ( Fig. 1 View FIGURES 1 – 20 ); mesosoma not wide, with mesopleuron not projecting; area superomedia elongate ( Fig. 31 View FIGURE 21 – 40. 21 – 30 ); second metasomal tergum almost as wide as long, sculptured. Ovipositor without notch ( Fig. 1 View FIGURES 1 – 20 ) as distinct from L. scutellatus ( Ashmead, 1890) .

Variation. Scutellum of paratype from Cleveland, South Carolina. dark.

Etymology. The species epithet, syringe , refers to structure of ovipositor.

Host. Unknown

Distribution. USA: SC; GA
