Named in reference to the host genus.

T. molecularis
sp. nov.

Description
. Female. Body length 3.0 mm; antenna
4.4 mm
; fore wing
3.1 mm
.
Antenna with
31
flagellomeres. First flagellomere
3.2
times longer than wide,
1.1
times longer than the second flagellomere. Median flagellomeres 2.0 times longer than wide. Width of head: width of face: height of eye =
2.7
: 1.0:
0.83
. Frons entirely flat, without any mid-longitudinal depression. Od
1.75
times POL and
0.7
times OOL. Inter-tentorial distance
2.5
times tentorio-ocular distance. Transverse diameter of eye 5.0 times longer than temple (dorsal view).
Mesosoma approximately
1.6
times longer than high, smooth and shining. Notauli remaining separate to posterior of mesoscutum where they are separated by a mid-longitudinal groove and coarser sculpture. Scutellar sulcus (prescutellar depression) with only single strong median carina. Precoxal suture moderately deep, foveate, sinuous, occupying
0.75
length of mesopleuron. Median area of metanotum with a weak mid-longitudinal carina. Propodeum with basal midlongitudinal carina on anterior third, giving rise to an elongate, pentagonal areola.
Wings. Marginal (radial) cell
2.8
times longer than maximum width. Vein R
1
a (metacarp) 1.0 times as long as pterostigma. Vein r-rs (first radial abscissa)
0.8
times as long as maximum width of pterostigma. Vein
3
RSa
(second radial abscissa) 4.0 times as long as vein r-rs (first radial abscissa) and forming very obtuse angle with it,
0.7
times as long as the almost straight vein
3
RSb (third radial abscissa),
1.7
times longer than vein
2
RS (first radiomedial). Second submarginal (second radiomedial) cell length
2.05
times maximum width,
1.1
times length of the wide first subdiscal (brachial) cell. Distance from vein
1
cu-a (nervulus) to vein
1
M (basal)
1.2
times vein cu-a (nervulus) length. First discal (discoidal) cell 2.0 times longer than wide. First subdiscal (brachial) cell 3.0 times longer than maximum width. Vein m-cu (recurrent) distinctly thickened and curved.
Hind
wing
4.5
times longer than wide. Vein M+CU (first mediocubital abscissa)
0.75
times as long as vein
1
M (second mediocubital abscissa). Vein m-cu (recurrent) weak, short, interstitial, almost straight.
Legs. Fore femur robust, 6.0 times longer than maximally wide. Fore tarsus
0.8
times as long as fore tibia. (
Hind
legs missing).
Metasoma. First tergite
1.07
times longer than posteriorly wide,
2.15
times longer than its minimum width; raised median area very finely irregularly longitudinally striate. Median length of second tergite
0.6
times its

basal width,
1.3
times length of third tergite. Ovipositor sheath
0.5
times as long as metasoma,
0.55
times as long as mesosoma,
0.24
times as long as fore wing.

sp. nov.
(13) Habitus, dorsal view; (14) Apex of antenna; (15) Base of antenna; (16) Head and anterior of mesosoma, oblique view showing separation of occipital and hypostomal carinae; (17) Head dorsal view; (18) Head subfrontal view;
