Genus HARLARUS gen.nov.

Type species: Harlarus titana sp.nov. Gender masculine.

Female. Length about 1.2-1.4mm.

Body robust, generally dark with a weak to moderate metallic sheen; funicle with pale and dark segments; dorsum of thorax with dark setae; legs generally dark with pale areas; wings hyaline; propodeum dark with a weak metallic sheen, side more strongly metallic, some silvery setae near spiracle; gaster dark with a metallic sheen.

Head in profile about 1.7X as high as deep, anteriorly fairly evenly curved from occipital margin to top of scrobes, less curved at top of scrobes and virtually straight to mouth margin, interantennal prominence hardly protuberant; occipital margin carinate; frontovertex slightly more than one-third head width and with fairly regular, polygonally reticulate sculpture and sparse, shallow piliferous punctures; ocelli forming a slightly obtuse angle; temple and gena with shallow, longitudinally elongate, polygonally reticulate sculpture; eye virtually reaching occipital margin, naked; scrobes shallow, Λ -shaped; antenna attached slightly below level of lower eye margin; scape strongly broadened and flattened, less than 2X as long as broad, about 0.5X as long as head width; funicle segments slightly longer than broad, gradually becoming slightly broader distally, linear sensilla on all segments except F1; clava shorter than funicle, 3-segmented, sutures subparallel, sensory area slightly enlarged, extending a little way along ventral surface giving clava a very slightly obliquely truncate appearance; malar sulcus present; mouth less than one-third head width, clypeal margin medially very slightly convex; mandible with one tooth and a broad, upper, slightly concave truncation; palp formula 4-3.

Thorax with pronotum very short; mesoscutum without notaular lines; scutellum with longitudinally elongate sculpture that is conspicuously deeper than sculpture on mesoscutum, apex and side smooth, setae sparse and evenly distributed; mid tibial spur shorter than basitarsus; fore wing fully developed; about 2.4X as long as broad; costal cell with only 1 line of setae ventrally and line of setae dorsally in apical two-fifths or so; submarginal vein with an apical hyaline break; marginal vein about 2X as long as broad, a little shorter than stigmal vein and hardly longer than postmarginal vein; linea calva open; filum spinosum present, consisting of a line of about 5 or 6 stouter peg-like setae; posterior margin of mesopleuron not reaching level with posterior margin of propodeum, falling short by distance equivalent to a little more than diameter of propodeal spiracle; propodeum short, virtually smooth medially and without a posterolateral tooth behind spiracle; about 15 setae near spiracle, extending part way to hind coxa.

Gaster with hypopygium not reaching apex; paratergites absent; syntergum shorter than mid tibia, apex more or less rounded; ovipositor not exserted, shorter than mid tibia, second valvifer with 3 or 4 subapical setae, its proximal part broadly C-shaped; hypopygium weakly W-shaped, posterior, median invagination moderately deep.

Male.Unknown.

DISTRIBUTION. Known only from Costa Rica, but likely to be more widespread in the Neotropics.

HOSTS. Unknown.

COMMENTS. Harlarus may be close to Dalek and similar genera (e.g. Hebynthus , Alkonia , Raquanus , etc.) that may form a monophyletic group, along with Caldencyrtus (see comments under Alkonia , p. 708). It can be separated from other genera in this group by having the scape less than 3X as long as broad, the funicle with dark and pale segments, all longer than broad, the clava shorter than the funicle with a weakly oblique, truncate apex, striate sculpture on the scutellum, the hypopygium not W-shaped and the ovipositor shorter than the mid tibia. See also comments under Sosara (p. 680).
