Charops Holmgren, 1859: 324

Type of the genus: Ophion (Campoplex) decipiens Gravenhorst, 1829: 596  by monotypy (= Charops cantator  De- Geer, 1778: 594)

Emended Diagnosis: relatively small to large sizes (fore wing 3.1 to 8.2 mm) covered with a silvery or golden pubescence; head strongly lenticular; mandible with a ventral flange; mandibular teeth small with equal or subequal sizes, and upper tooth broader than the lower tooth; clypeus slightly convex and rounded at apex; eyes strongly emarginate opposite to antennal socket; antennae filiform, usually not longer than half of the body; occiput subpolished and occipital carina reaching hypostomal carina at base of mandible; mesosoma  short, as long as or slightly longer than high; pronotum short, with transverse wrinkles; epomia strong to absent; mesoscutum without discernible notaulus; epicnemial carina present, extending to 0.5–0.75× the height of mesopleurum; scutellum subquadrate and not acutely carinate laterally, covered with long pubescence; metapleuron with juxtacoxal carina usually complete, sometimes strong on its anterior part and weak on its posterior part; propodeum with or without pubescence, usually rugose to reticulate and with elliptical spiracle; median longitudinal carina strongly present to absent; apex of propodeum close to the apex of hind coxa; legs with tarsal claws pectinate; fore wing areolet absent and 2 m-cu vein straight and vertical; metasoma long and strongly compressed; petiolar part of first segment very long, weakly up curved or straight; tergosternal suture in a dorsal position near base of petiole lateral and ventral near apex of petiole; postpetiole swollen and sometimes bulbous; glymma absent; ovipositor short, straight or upcurved, not projecting beyond apex of metasoma and with a distinct subapical notch.

Etymology: a female word from Greek (χάροψ) which means bright eyes (Hopper, 1959).

Comments: Charops  is easily distinguished from all other Campopleginae  genera by the following combination of characters: emarginate eyes, tergosternal suture near its upper margin, absence of areolet and relatively short ovipositor. Charops  is very similar to Scenocharops Uchida, 1932  , because they share the strongly emarginated eyes, the complete juxtacoxal carina, and the tergosternal suture near its upper margin, in lateral view. However, Scenocharops  presents a small petiolate areolet on the fore wing. In Brazil, Charops  can be easily misidentified as Casinaria Holmgren,1859  , since both genera have strongly emarginated eyes, and a suture separating the first metasomal sternite from the tergite near its upper margin, in lateral view. It is possible to discern Charops  from Casinaria  because the latter shows a petiolate areolet on the fore wings, and usually lack a complete set of propodeal carinae as well as the juxtacoxal carina.

Brazilian Charops  species have the juxtacoxal carina always present, sometimes faint on its posterior part; epomia present or absent; ovipositor straight or upcurved. It is possible to discern its species by studying the number of flagellomeres, format of supraclipeal area, presence or absence of epomia, the orientation of the propodeal carinae, ovipositor format and body coloration, that may vary in tone or pattern (illustrated for C. lucianae  ). Surface sculpturing may vary between faint to strong wrinkles on the mesopleura and the propodeum.

Charops  has been registered only in Southeast Brazil ( Fig. 2View FIGURE 2). However, its occurrence now seems to cover almost all of the Brazilian territory, except for the Midwest and Tocatins, both poorly studied regions (e.g. Fernandes et al. 2014 for Ophioninae  ).
