Subphylum Hexapoda (Hexapods)

Class Insecta (Insects)

Order Hymenoptera (Ants, Bees, Wasps and Sawflies)

No Taxon ("Parasitica" - Parasitoid Wasps)

Superfamily Ichneumonoidea (Braconid and Ichneumonid Wasps)

Family Braconidae (Braconid Wasps)

Tribe Euphorini

Genus Leiophron

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

see Euphorinae identification

first metasomal segment (petiole) long, narrow, tube-like, similar to this image

dorsal (a) and ventral (b) sides of petiole base not fused; separated by a suture

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.
