Description.
Female
(
Holotype
). Length,
2.3 mm
. Head orange; antenna (
Fig. 13
) with scape and clava brown to black, pedicel and F1 to F3 dark yellow, F4–F6 whitish; thorax dark metallic green, except pronotum, lateral margins of mesonotum, distal part of axillae and posterior margin of scutellum orange, tegula yellow, the apex translucent; mesopleuron orange; forewing (
Fig. 14
) with speculum and large circular band past venation brown, remaining part of the disc hyaline, venation dark brown, marginal vein (
Fig. 15
) darker; legs orange, apices of tarsi brown; gaster brown apex of gonostylus orange. Head about 4.4× as wide as frontovertex; ocelli forming an angle of about 70°; antenna (
Fig. 13
) with scape about 2.6× as long as broad, F1 slightly longer than broad and about 0.5× as long as pedicel; clava transversely truncate at apex. Relative measurements: HW 106, FV 25, POL 13, OOL<1, OCL 8, SL 36, SW 16.
Mesoscutum 0.7× as long as wide and 1.2× as long as scutellum. Forewing (
Fig. 14
) about 2.4× as long as wide; marginal vein (
Fig. 15
) about 1.2× as long as stigmal vein and 1.4× postmarginal vein. Relative measurements: FWL 130, FWW 54; MV 20, PMV 14, SV 16.
Gaster with ovipositor not exserted.
Paratype
: hypopygium (
Fig. 16
) about 3× as wide as long; ovipositor (
Fig. 17
) about 1.1× as long as mid tibia and 5× as long as gonostylus; Relative measurements: OL 180, MT 160, GL 35.
Male
. Similar to female but for antenna and genitalia. Scape about 2.4× as long as broad; pedicel subquadrate, all funicular segments longer than broad, their length decreasing towards the apex, F1 3× as long as broad and 4× as long as pedicel; clava about 3× as long as broad and as long as F6 and half F5 together. Relative measurements: SL 24, SW 10.
Variation.
None in the material at hand.
Hosts.
The species was reared from
Eulecanium
sp. (
Hemiptera
:
Coccidae
) on walnut (
Juglans regia
L.,
Juglandaceae
).
Distribution.
Iran
.
Material examined.
Holotype ♀, Iran, Kermanshah province, Kermanshah, 34°16'N 47°49'E,
5.vi.2010
, ex
Eulecanium
sp. (
Hemiptera
:
Coccidae
) on walnut, K. Jalilvand leg. Paratypes: 1 ♀, 1 ♂, same data as holotype. Holotype and 1 paratype will be deposited at NHM; 1 paratype will be deposited at DEZA.
Comments.
The species appears to be very close to
M. iranicus
and
M. sylvius
. Females of the new species can be separated from those of
iranicus
by the brown scape (orange in
iranicus
), proportion between head and frontovertex width (4.4× in the new species, 3.7× in
iranicus
), forewing 2.4× as long as broad (2× in
iranicus
) and with well-defined white band (irregular and faint in
iranicus
). Females of new species can be separated from
sylvius
by the relative proportions of the pedicel in respect to F1 (2× in the new species, 1.3× in
sylvius
) and by colour of antenna (with F4 yellowish slightly paler than F3 and slightly darker than whitish F
5 in
the new species, F4 brown as dark as F3 and distinctly darker than white F
5 in
sylvius
).
