Meteorus sibyllae
Stigenberg
sp nov.
Fig. 79E
,
125
Diagnosis:
Meteorus sibyllae
is most similar to
M. cespitator
and
M. jaculator
. It is most easily separated from
M. cespitator
on the body size. Whilst
M. sibyllae
belongs to the smaller species in the genus (length <
3.5 mm
),
M. cespitator
is distinctly larger (length>
3.5 mm
). The face of
M. sibyllae
is also more transverse and wider than that of
M. cespitator
(face 1.8 times as wide as high in the former, 1.5 times in the latter).
M. jaculator
is as small as
M. sibyllae
but has fewer antennal articles (
18–22 in
M. jaculator
,
24–26 in
M. sibyllae
).

Description:
Body 3.0 mm, forewing
3.2 mm
of
holotype
.
Paratypes
have 2.7–3.0 mm in body lengths.
Head: Length of eye equals the length of temple in dorsal aspect; eyes small, not convergent, slightly protuberant, smooth with punctation; width of face 1.8 times its height; OOL=3–3.5; clypeus distinctly shorter than the width of face, distinctly divided from face, convex, tentorial pits distinct; length of malar space 0.6 times basal width of mandible; mandibles stout and not twisted; antennal articles 24–26; 3rd antennal article 3.5 times longer than wide; all articles longer than wide, subapical articles 1.5 times longer than wide.
Mesosoma: Precoxal sulcus deep and narrow.
Wings: Fore wing: r/3–SR=0.4; C+SC+R/SR1=1.37; m–cu antefurcal; pterostigma brown with apical corner light. Hind wing: 1–M/cu–a=1.2;
Legs: Hind coxa rugose dorsally; hind femur 4.8 times longer than wide; tarsal claws small with no lobe.
Metasoma: Petiolar tergum apically 1.5 times longer than wide, 4.2 times as long as forewing; dorsope present; ventral folds of petiolar tergum not joined, dorsal aspect with no ridges, evenly curved with weak rugosity medially and striae laterally; ovipositor straight, slender; length of ovipositor 3.5–4.0 times that of petiolar tergum and 0.75 times forewing; propodeum with vague carina and reticulation.
Colour: Dark brown - black, clypeus yellow, legs yellow - brown, coxae dark brown.
