( Figures 1 (d), 3(a), 4(b))

Cardiochiles acrenulatus Fischer, 1958 . Polskie Pismo Ent . 28(2): 16, ♂. ‘ Wadi Digla , Ägypten ’ (Wien, ♂) (Leg. Priesner) .

Diagnosis

Generally yellowish with some black areas on different parts of body; temple moderately swollen behind eyes ( Figure 1 (d)); propodeum with various forms of blackish spots ( Figure 1 (d)); apical third of fore wing slightly infuscate ( Figure 3 (a)); vein 1-SR+M 7.0× as long as m-cu ( Figure 3 (a)); SMC2 0.45× as long as wide; spectral node of 3r may be present but hardly visible; hind tibia 7.2× as long as wide apically; inner hind tibial spur 1.35× as long as outer one ( Figure 4 (b)); stem of T1 2.6× as long as bulb ( Figure 1 (d)).

Abbreviated description of female:

Length of body: 4.5 – 4.8 mm; Length of fore wing: 3.1 mm.

Body generally yellowish with head largely black when seen in dorsal view; the following areas are black: vertex (shiny), upper face, frons (above and between antennal bases to vertex in the middle), apical half of mandibles, the proboscis (especially apically), entire antenna (with shiny and slightly paler scape and pedicel), three shiny lobes of mesoscutum (especially the middle lobe between notauli), scutellum, two sub-lateral semicircled spots on base of propodeum, hind coxa, middle band (dark hue) along metasomal T1 – 3. The remaining parts of all legs are uniformly yellow coloured. Fore wing: hyaline, weakly infuscated apically and ventrally; pterostigma almost black except basal orange area; parastigma and tegula are entirely orange; the veins are orange except veins M+Cu, 1-CUa, 1-Cub and 2CUa brownish.

Head: antenna with 31 flagellomeres, scape 2.4× as long as wide; galea 0.58× as long as height of eyes; glossa deeply bilobed, to about 0.3 – 0.4 of its length; OOL:AOL:POL: ØOD = 14:9:11:2. Fore wing: 1-SR+M 7.0× as long as m-cu; 2-SR+M about 4.0× as long as m-cu; 1-M straight, 1-SR slightly curved apically, junction of 4SRb and 5-SR forming a distinct angle, m-cu 0.25× as long as 1-M; discal cell 0.58× as long as wide; 1-A absent; 1-2A+3A spectral; 1-Cua 0.27× as long as 1-Cub; 2r 0.54× as long as inside height of SMC2, arising 0.5 – 0.6 along the length of stigma apically; stigma 3.4× as long as wide; angle between 4SRa and Rs 125°; angle between Rs and r-m 105°; spectral node of 3r present (very weak); SMC2 0.43× as long as wide; 2 + 3-SR slightly curved. Legs: Fore tibial spur 0.4× as long as basitarsus; hind tibia 7.2× as long as wide apically; inner hind tibial spur 1.35× as long as outer spur, 0.74× as long as basitarsus. Metasoma: T1 about 1.04× as long as broad; stem 0.36× as long as bulb; median field of T2 2.57× as broad as high; ovipositor sheath 0.3× as long as hind tibia.

Remarks

This is the first description of the previously unknown female of this species. In one of the examined specimens, the two black spots of the propodeum extended to almost the whole area of it.

Male

Unknown to us; according to the male holotype description ( Fischer 1958), it is very similar to the female but spots of mesoscutellum are paler and smaller, metasoma largely yellowish; antenna 30-segmented.

Material examined

1♀, Wadi Digla (29.932°N; 31.427°E), 28 April 1929 (Leg. Priesner) (det. P. Marsh) [ EFC]; 2 ♀♀, Gebel Elba (Bir = Wadi? Cansisrob) (22.243°N; 36.366°E), 28 January 1933 (Leg. Priesner) [ PPDD] .

Distribution

So far endemic to Egypt ( Fischer 1958 as Cardiochiles acrenulatus ; Yu et al. 2012).

Host records

Unknown.
