Macrocentrus collaris ( Spinola, 1808)

( Figs 1 (locality 8), 8A–D, 10C–E)

Bracon collaris Spinola, 1808: 140

Body length (female): 5.0 mm. (excluding ovipositor)

Coloration: head above antennae (dorsally), antennal scape and pedicel are dark reddish-brown; antennal flagellum black; propodeum dark reddish brown, slightly paler posteriorly; metasoma (except T2 medio-laterally orange) as well as ovipositor sheath dark brown to black. Frons (anteriorly behind antenna) clear reddish brown; clypeus and supraclypeal area, mandibles (except black apex) yellowish to orange; mesoscutum and scutellum reddish or yellowish; palpi and legs entirely yellowish; ovipositor yellow to orange, ovipositor sheath dark brown to black. Wings hyaline giving off some colored reflections apically, veins pale brown, pterostigma dark brown, largely yellow at base.

Diagnosis. eye in dorsal view 2.3 × as long as temple; inner margin of eye (just behind antennae) with short, fine yellowish pubescence; malar space distinctly shorter than basal width of mandible; clypeus slightly convex, wider than long (i.e. transverse); face smooth medially; antennal F1 1.3 × as long as F2, and 4.8 × its width apically; mandibles crossing, with inner tooth sharp and obviously shorter than outer one; temple smooth and shiny, shorter than longitudinal eye diameter; mesosoma relatively long, 1.65 × as long as its height; mesoscutum with deep notauli, dividing mesoscutum to three convex lobes that are smooth and shiny, posterior margin of mesoscutum with deep rounded depression; propodeum coarsely, transversely rugose; lateral sides of pronotum (propleuron) rugose; mesopleuron finely and superficially punctate; fore wing with r: 3-SR: SRl = 2.9: 5.2: 21; T1 1.7 × as long as its apical width; metacoxa relatively large, more than two times as long as mesocoxa; claws simple; metasomal T1 narrowed toward base, 1.7 × as long as its apical width; T2 distinctly longer than T1, parallel sided; ovipositor, at most, as long as metasomal length, with sharp pointed end, without subapical notch, ovipositor sheath flexible, 0.62 × as long as fore wing, densely setose.

Male: resembles female except for: body including antenna black; legs with coxae, trochanters and femora are dark yellow to brown, rest yellowish; pterostigma narrower and largely dark brown except a small yellowish area at base; clypeus and supra-clypeal area as well as basal half of mandible, palpi somewhat yellowish to orange in color.

Remarks: This species, as in all macrocentrines, has small pegs on the front side of trochantelli. Based on van Achterberg (1993a), they vary in number (2 or 3) and size (small or minute) in the different examined specimens in this species. In the Egyptian specimens, only two pegs can be seen under high magnification.

Material examined: 1♀, 1♂, Ismailia, El Tal El Kebeer [30°25’19.512” N, 32°17’42.58” E] ( Fig.1 , locality 8), 4.x.2012, Malaise trap, leg. Samar Mahmoud .

General distribution: Widely distributed in the Afrotropical, Neotropical, Oceanic, Oriental, and Palaearctic regions ( Yu et al. 2016).
