03AE87A6FF96384CFE76FF3921AF1380.taxon	diagnosis	Diagnosis The genus has two main diagnostic characters, which are shared by most species: the single perpendicular tooth on tarsal claws (multidentate in Elampus Spinola, Holophris Mocsáry, Holopyga Dahlbom and Omalus Panzer); and the transverse anterolateral pronotal carina (absent in Elampus, Hedychrum Latreille and Holopyga). Other morphological remarks of the genus refer to the unvarying wing venation pattern, and the absence of other distinctive features of related elampine genera, such as: oral fossa without medial process (present in Hedychrum); metatibia without fossa (present in Hedychrum); mesopleuron without distinct omaulus or scrobal carina (present in Omalus and Holophris); mesoscutellum without anterolateral tubercle (present in Exallopyga French); apical margin of T 3 evenly rounded (with apical notch in Holophris, and produced into a snout-like process in Elampus); fore wing entirely setose (at least partly asetose in Holophris and Elampus); M of fore wing straight or gently curved (strongly angulated in Elampus and Holopyga); metanotum round (mucronate in Elampus).	en	Lucena, Daercio (2018): The uncommon genus Hedychridium (Hymenoptera: Chrysididae) in South America: new species and first record for Brazil.

03AE87A6FF963849FE13FC2B232816BC.taxon	diagnosis	Diagnosis The new species can be readily distinguished by distinctive traits that are absent in H. argentinum such as: second tarsomere of metaleg with double line of spines; metabasitarsus with apical crown of spines; mesoscutal integument rugulose to striate anterolaterally; fore wing entirely setose; apical margin of T 3 with narrow translucent edge; compound eyes with sparse short microtrichia.	en	Lucena, Daercio (2018): The uncommon genus Hedychridium (Hymenoptera: Chrysididae) in South America: new species and first record for Brazil.

Legs: tarsal claw with single perpendicular submedial tooth; metabasitarsus with crown of spines apically; second tarsomere of metaleg with double line of spines on ventral surface; metafemur enlarged. Wings: fore wing entirely setose (as in Figure 2 (h )); M gently curved, almost straight, arising slightly after 1 cu-a; Rs short, evenly curved, tubular proximally, fading distally; A 1 tubular at cu-a intersection, fading gradually. Pronotum: clearly narrower than head; medial notch slightly marked; anterolateral margin discretely carinate; lateral depression roughly sculptured. Mesoscutum: integument somewhat rugulose, striate anterolaterally; notauli deeply impressed; parapsidal lines discrete, surrounded by punctures. Mesopleuron: round, gently deflected posteriorly, with discrete scratch marks, scrobe deeply marked. Mesoscutellum: one-third as long as mesoscutum. Metanotum: posterior margin convex, as long as mesoscutellum. Propodeum: dorsal surface macro-foveolate, V-shaped; lateral process with some striate marks both dorsolaterally and lateroventrally; lateral process pointed apically. Metasoma: T 3 with narrow apical translucent edge; margins smooth, round, without notch or corners; S 1 polished; S 2 – S 3 with silvery semi-decumbent setae. Punctation: head regularly punctate, changing abruptly in the scapal basin, which is densely striated (as in Figure 1 (e )); mesosoma mostly foveate, with some rugulose and striate areas marginally; metasoma with integument predominantly puncticulate, with discrete striate marks laterally on T 2 and entirely on T 3; T 1 – T 2 finely punctate, distinctly shallower than the rest of body, with broad shiny interspaces among well-separated punctures. Male (Figure 2 (a – h )). Similar to female, except: distinct bronze shine on frons (Figure 2 (c )), pronotum, mesoscutum and T 1 – T 2 (Figure 2 (a )); mesosoma primarily green blue, with bluish highlights on pronotum, mesoscutellum, metanotum and propodeum; large dark blue band covering the mesoscutum (Figure 2 (b )); tibiae brownish green; T 1 light green marginally, with dark blue band on disc; T 2 light green marginally, with large dark blue band occupying much of disc (Figure 2 (d )); T 3 light green with bluish tint on disc; metafemur not so enlarged as in females; genital capsule (Figure 2 (e – g )), gonocoxal lobes widely fused dorsally, lobes as long as aedeagus; cuspis with long apical setae.
