Notes Holotype deposited in MZLU, paratypes in MZLU, NHM, ZSM.
Host Gregarious endoparasitoid on Arge ustulata(L.) ( Hymenoptera: Argidae), 14♀ and 3♂ have been reared from the same host specimen. The label information does not specify which stage of the sawfly that was parasitised. Another Tetrastichusspecies, T. hylotomarum, has been recorded from larvae and pupae of Argespp. (Graham 1991), but not specifically A. ustulata.
Additional paratypes (not barcoded) 1♀ 1♂ "SWEDEN, Skane, Kullaberg, 28.ii.1966, P. Benander, ex Arge ustulata".
