Diagnostic characters.  
  Female. Head : compound eye with sparse and short setation throughout (Figs 1 A, 2 B, 3 B, 4 A, 8 C); vertex shallowly and evenly granulate (Figs 1 C, 2 B, 3 B, 4 A, 8 C); occipital carina complete (Fig. 8 A); hyperoccipital carina present directly behind the lateral ocellus, carina sharp and well defined, sculpture smooth along posterior margin of carina (Fig. 8 C); outer orbital furrow wide (2–2.5 times as wide as an ommatidium) (Fig. 8 C); clypeal sensillum present above the line connecting the medial and lateral clypeal setae (Fig. 8 E).   
 Mesosoma: mesoscutal humeral sulcus (mshs) present as a smooth furrow (Figs 1 B, 2 D, 9 A); metapleural carina in antero-dorsal area of metapleuron (pdms, between metapleural arm and propodeal spiracle) complete, distinct and strong (Fig. 9 A); surface of the furrow between metanotal trough and metascutellar arm (msn) usually crenulate (Fig. 9 A); mesoscutum longitudinally strigose posteriorly (Fig. 9 C); median mesoscutal sulcus present in largest specimens, barely visible in smaller ones. Fore wing postmarginal (pm) and stigmal (st) veins length ratio: pm: st = 1.9: 1 (n = 20) (Fig. 3 A). Hind femora dark brown with yellowish tips (Fig. 2 C, D).   
 Metasoma: first metasomal tergite with one or rarely two pairs of sublateral setae (ss) (Figs 1 C, 2 C, 9 E).   
  Male. Head : antennal length ratio A 3: A 2 = 1.2: 1 (n = 20), antennomeres A 6 – A 11 bead-like, subequal (Fig. 3 C). Genitalia: basal ring ratio: Length: Width = 6: 5; minimum distance between inner margin of laminae volsellares: narrow (laminae volsellares lyre-shaped); external margin of penis valve more intensely sclerotized curved and distally converging (Fig. 3 D). Hind femora yellow to pale brown. Other morphological characters as in female.   
 From the analysis of the lectotype of Te. heydeni (NHMW - HYM # 0005387), the combination of morphological characters (Fig. 4) coincides with the characters of the lectotype of Te. truncatus (OXUM 0011), and the length ratio between the A 3 and A 2 antennomeres (Fig. 4 A) matches with that of the male of Te. truncatus (Fig. 3 C). Therefore, Te. heydeni is here considered a junior synonym of Te. truncatus.   
Biological information.  
 Host species associated: Table 2. The specimen DISAFA - FT HYM- 0657 - OQ 466097 was found overwintering in November in Viburnum leaf mines created by P. viburni; the specimens AVT 001908 and AVT 001909 were found already dead in egg-mass of Lymantria monacha (Linnaeus) (Lepidoptera, Erebidae), presumably after wintering.   
DNA barcoding.  
 Barcode sequences were obtained from 49 specimens of Te. truncatus. Pairwise distance values within species are shown in Suppl. material 3. The genetic distances between the insects identified as the same species were between 0.000 and 0.074 (mean 0.013 + / - 0.003). The analysis of COI sequences discovered that Te. truncatus includes the specimen OL 631282, previously identified as Telenomus sp. (Ricupero et al., 2022) (Suppl. material 1).
