Synonyms and other taxonomic changes
Leiophron Nees 1819
Junior synonym: Liophron Forster 1862 (Dicky Sick Ki Yu 2012 (1))
Numbers
69 species world-wide(1), about 19 described North American species (Shaw, S.R. 1997. Subfamily Euphorinae. In:(2))
Size
Generally 4 mm or less
Identification
first metasomal segment (petiole) long, narrow, tube-like, similar to this image
occipital carina either absent or if present, incomplete dorsally
wings with fore wing vein 3RS abruptly curving apically to intersect with the costal vein near the stigma and far from the wing apex. fore wing cells either complete, veins fully sclerotized, or as in this figure (some veins missing, incomplete, and/or spectral). (Shaw, S.R. 1997. Subfamily Euphorinae. In:(2))
Range
Cosmopolitan except Australia
Food
late stage nymphs and adults of Miridae (plant bugs).
Life Cycle
Solitary koinobiont endoparasitoids. Click here for parasitoid terminology.
Remarks
Closely similar to euphorine genus Peristenus. Can be separated from Peristenus by:
occipital carina absent or incomplete dorsally (complete in Peristenus)
some fore wing veins often incomplete, absent, and/or spectral, thus marginal and discal cells often open apically (always complete in Peristenus)
petiole with tergum (dorsal side) and sternum (ventral side) separated by a suture (fused in Peristenus)
For biocontrol potential, see Remarks under Euphorinae.
