Chrysidid systematics

The fundamental morphologic features which distinguish chrysidids from the other wasps are:

• reduction of the number of the visible abdominal segments to 5 or less
• an internal ovipositor or genital tube, constituted by the remaining abdominal segments
• 11 antennal articles (flagellomeres), plus pedicel and scape
• labial palps with 3 articles and maxillar palps with 5 articles
• fore wings with 5 closed cells, or less, and
• hind wings without closed cells.

According to the Zoological Record, Chrysidids are ranked in the taxonomic hierarchy as Aculeate Wasps, wasps equipped by a stinging apparatus. But, according to the present-day classifications, the traditional sections (infraorders) 'Terebrantia' ('Parasitica') and 'Aculeata' of the Suborder 'Apocrita' have been abandoned in the direction of taxonomy based on Superfamilies.

The Family Chrysididae comprises 5 Subfamilies and 83 Genuses. Their taxonomy down to the Genus level is as follows:
