Belongs within: Bembicidae.
Contains: Epinysson, Zanysson, Nysson, Synnevrus, Brachystegus.

The Nyssonini are a group of medium-sized to small wasps, usually with a heavily armoured integument, that are kleptoparasites of other Bembicidae or Crabronidae (Bohart & Menke 1976).

Characters (from Bohart & Menke 1976): Eyes converging below, often strongly, inner margins slightly to moderately emarginate above; ocelli well developed. Labrum small to rather large, in latter case broadly subrectanpular; palpal formula 6-4; pronotum closely appressed to scutum. Scutum with admedian lines fused into a single line at or very near anterior edge; notauli absent; with oblique scutal carina; scutellum without posterior overlapping edge. Omaulus usually present, sometimes indistinct; acetabular carina present, sometimes faint; subomaulus present; episternal and scrobal sulci absent or evanescent; sternaulus absent; verticaulus sometimes present. Metapleuron not always separated from propodeum by a distinct sulcus or line beneath upper metapleural pit; propodeum usually spined dorsolaterally. Midcoxae widely separated, precoxal sulcus complete or sometimes obscure; midtibia usually with two apical spurs (exceptionally one); foretarsal rake weak or absent; arolia small or absent; plantulae present but usually very small. Forewing media usually diverging at or before cu-a; stigma usually rather small; two or three submarginal cells, true second cell petiolate (when present) and receiving at least one recurrent vein. Hindwing media diverging before to after cu-a; jugal lobe small or absent. Gaster with tergum I nearly as broad as II and with lateral line or carina; sternum I with a double ridge converging basally; male with seven visible terga; male sternum VIII simple; male genitalia with volsella undifferentiated into cuspis and digitus; female pygidial plate usually well developed but sometimes indistinct, and with entire pygidium serrate or multidentate.
