Head about 6.1X as wide as frontovertex, in profile about 1.7X as high as deep, tangent to frontovertex forming an angle of about 85° with that of face; occipital margin acute, not carinate; an elongate, shiny bottomed, oval depression adjacent to eye immediately behind posterior ocellus; ocelli of normal size, forming an angle of about 40°; frontovertex ( Fig. 312) moderately shiny with shallow, polygonally reticulate sculpture of mesh size clearly smaller than eye facet; temple and gena with very shallow, longitudinally elongate, fine, polygonally reticulate sculpture; top of scrobes, interantennal prominence and mouth margin with shallow, regular, polygonally reticulate sculpture; scrobes extremely shallow, indistinct; antenna as in Fig. 311; scape very slightly broadened and flattened, about 3.7X as long as broad; funicle with F1-F3 smaller, subequal, subquadrate, F4-F6 larger, gradually increasing in size distally, subquadrate, linear sensilla present only on F4-F6; clava very slightly longer than F2-F6 combined, sutures parallel, outer suture incomplete and dorsally oblique; sensory area small, at apex only giving it a rounded appearance; eye slightly overreaching occipital margin, naked; malar sulcus present, but incomplete and very inconspicuous; clypeal margin weakly emarginate medially; mandible with one acute tooth and a broad, straight truncation. Relative measurements: HW 67, HH 57.5, FV 11, POL 3, OOL 0, OCL 7.5, AOL 8.5, EL 37.5, EW 38.5, MS 30, SL 33, SW 9.

Thorax with visible part of mesoscutum about 1.9X as broad as long; scutellum about 1.5X as broad as long with subapical setae about 0.7X its length; hind femur about 3.6X as long as broad; fore wing with venation and setation as in Figs 314, 315; propodeum medially about 0.05X as long as scutellum. Relative measurements: FWL 77, FWW 31.5; HWL 56, HWW 13.

Gaster with hypopygium reaching about 0.7X towards apex; last tergite about 0.7X as long as mid tibia, with apex broadly truncate; ovipositor exserted, the exserted part about 0.4X as long as mid tibial spur or about 0.15X mid tibia; posterior margin of hypopygium virtually straight with hardly a median invagination ( Fig. 316). Relative measurements: OL 75, GL 17.5 [MT 69.5].

Variation. Females vary in overall length from 1.15-1.18mm, the shiny bottomed depression adjacent to eye immediately behind posterior ocellus may be small and difficult to see, otherwise little variation noted in material examined.

Male. Unknown.

MATERIAL EXAMINED.

Type material. Holotype E: COSTA RICA, Puntarenas, RF Golfo Dulce , 24km W Piedras Blancas, 8°46’N 83°24’W, 200m, xi.1990 (P. Hanson) . Paratype: COSTA RICA; 1E, Heredia, Est. Biol. La Selva , 10°26’N 84°01’W, 75m, 28-29.ii.2008 (J.S. Noyes) . Holotype and paratype in NHMUK .

COMMENTS. Neococcidencyrtus cyclope is extremely similar to drysus . Apart from the relatively narrower frontovertex and a brown spot on the occiput above the foramen (see key), cyclope differs from drysus in having the mandible with one acute tooth and a very broad, straight upper truncation and the posterior margin of the hypopygium virtually straight. In drysus the mandible is tridentate with a longer, lower acute tooth and two shorter upper teeth and the posterior margin of the hypopygium is distinctly biconvexly curved either side of a moderately deep invagination.
