Etymology.

The species is named in honour of A. van Harten for his outstanding collecting of arthropods from the Arabian Peninsula and for his impressive book series on the arthropod fauna of the United Arab Emirates.

Description.

Female. Fore wing length 2.5-2.8 mm. Head. Width of head (dorsal view) 1.9-2.0 × its median length. Transverse diameter of eye (dorsal view) 1.9-2.1 × length of temple. OOL 3.0-3.2 × Od; POL 1.3-1.4 × Od; OOL 2.1-2.4 × POL. Longitudinal diameter of eye (lateral view) 1.3-1.4 × its transverse diameter. Face medially weakly, but widely elevated, with complete, very high medio-longitudinal carina, 1.5-1.7 × as wide as high. Longitudinal diameter of eye 2.8-3.0 × height of malar space (anterior view). Malar space 0.85-0.90 × base of mandible. Malar suture deep, smooth. Width of hypoclypeal depression 1.1-1.4 × distance from depression to eye. Antenna with 28 antennomeres, ca. 1.1 × as long as fore wing. First, middle and penultimate flagellomeres 2.1-2.5 ×, 1.7-1.9 ×, and 1.9 × as long as wide, respectively. Mesosoma 1.6 × as long as high. Mesoscutum setose on notaulic area and posteriorly, anteromedially widely glabrous. Propodeum with short branching medio-longitudinal keel apically and weak medio-longitudinal impression in basal half. Wings. Vein r arising from basal 0.37-0.40 × of pterostigma. Vein 1-R1 1.8-1.9 × as long as pterostigma. Marginal cell 19-26 × as long as distance from its apex to apex of wing. Vein 3-SR 2.3-2.5 × vein r, 0.55-0.60 × vein SR1, 2.0-2.2 × vein 2-SR. Vein 2-SR+M ca. 0.6 × vein 2-SR, 0.90-0.95 × as long as vein m-cu. Vein cu-a weakly postfurcal. Legs. Hind femur 4.4 × longer than wide. Fifth segment of hind tarsus 0.85-0.92 × as long as second segment, 0.5 × as long as hind basitarsus. Claws with shortly protruding and blunt basal lobes. Metasoma. Median length of T1 0.65-0.75 × its apical width; margin of its median area crenulate. T1 with incomplete dorsal carinae and with weak sublateral posteriorly converging carinae; dorsolateral carinae of T1 developed. T2 medially 1.2-1.4 × as long as T3; basal width of T2 1.7-1.8 × its median length. Anterolateral areas of T2 round, weakly separated by roundly converging sublateral carinae and shallow crenulate furrows delineating not elevated subparallel-sided median area. Dorsolateral impressions of T2 absent; spiracle located in middle of T2, on dorsum of tergite. Suture between T2 and T3 deep, weakly curved, and crenulate. Apical margins of T3-T6 with shallow, weakly crenulate transverse subapical grooves. Ovipositor sheath 1.00-1.05 × and 0.31-0.32 × as long as hind tibia and fore wing, respectively. Sculpture and colouration. T2-T3 longitudinally rugose to granulate-rugulose. Body mainly reddish yellow, mesosoma reddish brown; malar space pale yellow; tegulae yellow; pterostigma yellow; wing veins pale brown; wing membrane weakly darkened, lighter apically.

Male. Fore wing length 2.1 mm. Transverse diameter of eye (dorsal view) 2.3 × length of temple. OOL 2.2 × Od; POL 1.1 × Od; OOL 2.0 × POL. Longitudinal diameter of eye 3.9 × height of malar space (anterior view). Malar space 0.75 × base of mandible. Malar suture weak under eye, deep near mandible. Antenna with 27 antennomeres. Mesosoma 1.7 × as long as high. Vein 2-SR+M 0.85 × vein m-cu. Median length of T1 0.85 × its apical width. Metasoma yellow with pale yellow T1-T2; pterostigma brownish yellow. Otherwise similar to female.
