Material examined. HUNGARY: 1 ♀ (holotype) “ Hortobágy, Kunmadaras, Dög-halom ”, “ 1974.VI.13 leg. Kaszab ”, “ Holotypus Neolonchetron hungaricum Szel. ”, “Hym. Typ. No. 6914 Mus. Budapest ”, “ ♀ Stenetra hungarica (Szel.) det. Z. Bouček ” ( HNHM) . FRANCE: 1 ♀ “Yaucluse: nr. Bëdoin, 17.07.1980 ”, “near Apeliome”, “ Stenetra hungarica Sz. M. de V. Graham det. 1994(44)”, “ NHMUK 013455979 ” ( BMNH) .

Distribution. Western and Eastern Europe ( France, Hungary).

Comments. Stenetra hungarica belongs to a group of five species that have a head and mesosoma with thin, inconspicuous dark pilosity and the stigma of the stigmal vein comparatively narrow; differences from between species are shown in the key in couplets 5–8. Females of S. hungarica are also similar to those S. californica , as is discussed under the latter species.
