Female.
Holotype
. Length, head + mesosoma,
0.65 mm
. (Metasoma distorted on card). Head golden yellow; a short black band between each torulus and eye margin present. Mandible with tip black. Palps white. Antenna (
Fig. 3
) with radicle black; scape white, with a brown band medially (the band incomplete dorsally on inner surface and ventrally on outer surface); pedicel with basal half dark brown and apical half white; F1 dark brown; F2–F6 white with pale brown suffusions, each segment apically brown, but on slide F2–F6 appear brownish yellow; clava with first segment brownish yellow, distal two segments brown. Mesosoma white; dorsum with pale brown suffusions; pronotal collar and sides white, anteriorly dark brown; anterior margin of mesoscutum dark brown; tegula white with apex brown; propodeum white, between spiracles pale brown; prepectus, mesopleuron and metapleuron white. Wings hyaline; fore wing with setae on veins, and setae on distal third of disc pale brown; otherwise discal setae hyaline. Legs, including coxae, pale yellowish white. Gaster with dorsum brown; basal half laterally white; apical half of ovipositor sheaths (= third valvulae; gonostyli) dark brown.

Anagyrus azolus
Hayat
,
sp. nov.
Female: 3, antenna; 4, head, frontal view; 5, fore wing; 6, outer plate of ovipositor; 7, hypopygium.
Head. Frontovertex width 0.43× head width; ocellar triangle with apical angle obtuse; posterior ocellus 1.55× diameter of an ocellus to eye margin; POL about 3.25× as long as OOL; head, in frontal view (
Fig. 4
), 1.12× as broad as high; eye height 2.87× malar space; frontovertex and face with fine rugose-reticulate sculpture and with white setae; eyes setose, setae hyaline, and each seta shorter than a facet. Antenna (
Fig. 3
) with scape slightly broadened, 4.33× as long as broad; pedicel 2.5× as long as broad, 0.41× scape length, and slightly longer (1.15×) than F1; F1 longest segment, 3× as long as broad, and 1.26× as long as F2; F2–F6 subequal in length and gradually increasing in width, so that F6 is 1.33× as broad as F2; clava 1.4× as broad as F6, and as long as distal half of F4 and F5 and F6 combined.
Relative measurements
(
holotype
, slide)—head frontal width, 48; frontovertex width, 21; head frontal height, 39.5; eye height, 29; malar space, 10.5; antennal scape length, 21.
Mesosoma. Mesoscutum and scutellum with sculpture similar to that on frontovertex; setae silvery white including those on propodeum distal to spiracles; propodeum with 3–4 setae mesal to each spiracle. Fore wing (
Fig. 5
) 2.45× as long as broad; linea calva interrupted by 5–6 lines of setae, and closed posteriorly by 4 lines of setae; costal cell with 2 lines of setae on ventral surface; marginal vein 3.5× as long as the short postmarginal vein, both combined very slightly longer (1.08×) than stigmal vein.
Hind
wing 4.7× as long as broad.
Relative measurements
(
holotype
, slide)—fore wing length (width), 108 (44); hind wing length (width), 82.5 (17.5); mid tibia length, 39; mid basitarsus length, 13; mid tibial spur length, 9.5.
Metasoma. Hypopygium as in
Fig. 7
; outer plate of ovipositor as in
Fig. 6
.
Relative measurements
(
holotype
, slide)—TVII length, 62; ovipositor length, 73; third valvula (fused with second valvifer) length, 14.

Etymology.
The species name is derived from an arbitrary combination of letters, and may be taken as a noun in apposition.
Comments.
This new species is apparently similar to
Anagyrus floris
Noyes & Hayat (1994)
, although it does not run to this species in the key because of the relatively longer antennal scape. It differs from
A. floris
in the following characters: antennal scape 4.33× as long as broad; F2–F6 white with pale brown suffusions and each segment apically brown; first segment of clava brownish yellow and distal two segments brown; head without a dark spot on malar sulcus between the eye and mouth margin; thoracic dorsum largely white with pale brown suffusions, except pronotum anteriorly and anterior margin of mesoscutum dark brown. In
A. floris
:
antennal scape 3.77× as long as broad; F2 whitish, F3 whitish to yellowish brown, and F4–F6 and clava brownish yellow; a dark brown spot present on each malar sulcus between the eye and mouth margin; colour of thoracic dorsum variable, but in the
holotype
, lemon-yellow with sides paler.
The new species is quite different from all the South African (
Prinsloo 1998
;
Compere 1939
), the Costa Rican (Noyes 2000) and the Palaearctic species (
Trjapitzin 1989
).
