Negev Desert, Sde Boker Kibbutz, 2-22.x.1988 , F. Brouwer [1♀ on slide, UCRC ]. Description. FEMALE (specimens from China and Israel ). Body yellowish-brown except eyes red, legs yellow. Body length 0.55–0.63 mm (n = 7). Head brown, subcircular in frontal view; eye 0.68× height of head (0.57–0.80). Maxillary palp short, 1- segmented. Antenna ( Fig. 11 ) rather long, with scape long, 4.28× as long as wide (4.00–4.43×); pedicel pyriform, 2.50× as long as wide (2.00–2.50×); scape length/pedicel length = 1.50 (1.47–1.55); second anellus small and appressed to club; club 3-segmented, 3.58× as long as wide (2.92–4.00×), first segment the shortest, apical segment the longest and with 3–4 PLS, terminal process as long as second claval segment, its length/ club length = 0.14 (6/ 42). Mesoscutum with reticulate sculpture; midlobe with 4 setae. Fore wing ( Fig. 12 ) 2.00× as long as wide (1.9– 2.1×), hyaline; venation short, extending 0.30× FWL, disc sparsely setae, with setae irregularly arranged. Fringe setae short, FWFS/FWW = 0.20 (0.14–0.20). Hind wing with 1 complete linear setal track. First tarsal segments of all legs short, second and third segments equal in length. Metasoma longer than mesosoma; ovipositor short and slightly exerted, arising from fourth gastral sternite, ovipositor/hind tibia length = 1.15 (1.17–1.25). Measurements (µm) of the holotype . Body 610; mesosoma 180; gaster 300; ovipositor 37.5. Antenna: scape 70; pedicel 50; clava 110. Fore wing 390: 200; longest marginal seta 40. Hind wing 370; 30; longest marginal seta 60. MALE (specimens from China ). Body length 0.60–0.62 mm ; body color and morphological features similar to female. Antenna ( Fig. 13 ) slightly thick, scape length/pedicel length = 1.36 (1.15–1.44), scape 3.65× as long as wide (3.14–4.00×); pedicel 1.98× as long as wide; second anellus larger than first; club 5-segmented, 3.06× as long as wide (2.83–3.50×), with 2 PLS, one on the third club segment, another on the fourth to fifth club segment. Genitalia ( Fig. 14 ) cylindrical, aedeagus and apodemes equal in length. Diagnosis. Tumidiclava tamariska is most similar to T. longiclavata . Females of this new species are easily distinguished by the unique combination of the club having long segments, particularly the second and third segments ( Fig. 11 ), and the fore wings having sparse, short, inconspicuous discal setae ( Fig. 12 ). Etymology. The species name is a noun in apposition which is derived from the common name of Tamarix , tamarisk. Distribution. China (Xinjiang) and Israel . Hosts. Unknown. Comments. Most of the specimens of this species were collected in Beitun, Xiganqu saline desert. Vegetation at this locality is predominated by Tamaricaceae , plant hosts of various leafhoppers (Hemiptera: Cicadellidae) and also the leaf beetle Diorhabda elongata Brullé ( Coleoptera : Chrysomelidae ). At least one of these two might be the potential host of T. tamariska , numerous specimens of which were collected on Tamarix chinensis .
