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
).
Telenomus truncatus
. Female lectotype (OXUM 0011): head in frontal view (
A
); habitus in lateral view (
B
); habitus in dorsal view (
C
). Scale bars: 0.5 mm.
Telenomus truncatus
. Female (
DISAFA
- FT HYM- 0519): head in frontal view (
A
); head in dorso-lateral view (
B
); habitus in dorsal view (
C
); habitus in lateral view (
D
). Scale bars: 0.2 mm.
Telenomus truncatus
. Female (
DISAFA
- FT HYM- 0650): fore and hind wings (
A
). Male (
DISAFA
- FT HYM- 0516): head in frontal view (
B
); antenna (
C
); genitalia (
D
). Scale bars: 0.2 mm.
Telenomus heydeni
. Male lectotype (
NHMW
- HYM # 0005387): head in frontal view (
A
); habitus in lateral view (
B
); habitus in dorso-lateral view (
C
). Scale bars: 0.5 mm.
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
).
