Dinetus rakhimovi Mokrousov et Khedher , sp. nov.
( Figs 1–7 View FIGURES 1–7 )
Diagnosis. A member of the D. dentipes species group, which also includes D. arenarius Kazenas, 1973 , D. dentipes E. Saunders, 1910 , D. psammophilus Kazenas, 1977 , D. turanicus Kazenas, 1993 , D. wojciechi Kazenas, 1998 and is characterized by having the ocellocular distance shorter than the hind ocellar diameter, the head and mesosoma (at least mesopleuron) with long erect setae ( Fig. 1 View FIGURES 1–7 ); the apex of the marginal cell truncate, the second section of the cubital vien of the subdiscoidal cell nearly vertical ( Fig. 3 View FIGURES 1–7 ). From all species of the D. dentipes species group, D. rakhimovi differs by having long subparallel apical clypeal teeth ( Fig. 6 View FIGURES 1–7 ). From the similarly colored D. dentipes , D. psammophilus and D. turanicus , it differs by having the propodeal enclosure with reduced yellow coloration and more developed appressed silvery pubescence ( Fig. 2 View FIGURES 1–7 vs Fig. 18 View FIGURES 17–21 ). From the morphologically similar D. arenarius and D. wojciechi , it differs by having largely developed light coloration (head and legs almost completely yellow, ventral part of mesosoma completely yellow).

Description. Female. Body length 4.9 mm; fore wing length 2.8 mm.
Head 1.28× as wide as long in frontal view. Eyes diverge sharply downward, ratio of minimal distance at vertex to maximal below is 0.45×. Ocellocular distance distinctly shorter than hind ocellar diameter. Occipital carina well developed dorsally, evanescent ventrally. Clypeus with pair of long subparallel semitransparent apical teeth. Basal ventral surface of mandible with well-developed tooth and weak notch distally; apical part of inner side simple, without additional tooth. Antenna normal; scape not long, it length about half frons height; ratio length of scape and flagellomeres I, II, III is 1:0.63:0.57:0.45. Head predominantly with obscure dense punctation, with appressed silvery pubescence almost over entire surface (denser on clypeus and frons) and with long erect setae on gena (psammophore), ocular area and shorter on frons and vertex. Areas laterally of hind ocelli and occipital area shagreened and without setae. Underside of head smooth and shiny. Mesosoma with obscure dense punctation, with appressed silvery pubescence almost over entire surface and with long erect setae on propleuron (psammophore), mesonotum and mesopleuron. Propodeal enclosure with shagreen sculpture, only central part without appressed silvery pubescence. Ventral part of mesosoma smooth and shiny. Fore coxa, fore trochanter and fore femur normal, with long setae of psammophore; tibia with anterior and posterior rows of several bristles; tarsal rake well developed, spines slightly expanded, fore tarsomere I with seven spines; apical tarsomeres elongate, near parallel sided, with lateral stout spines. Apex of marginal cell truncate, second section of cubital vien of the subdiscoidal cell nearly vertical; hind wing media diverging slightly before cubito-anal crossvein. Metasoma with delicate shagreen sculpture; terga 1–5 with apicolateral patch of silvery pubescence, more developed on terga 1–3; pygidium slightly elongated, smooth, with several punctures; sterna 2–5 with apical and sternum 6 over the entire surface with sparse erect setae.
Head yellow with black ocular and occipital areas; mandibles yellow with darkened apex; scape yellow with dorsal darkening, pedicel, flagellomeres I and II from above yellow, remaining parts of the antenna darkened. Mesosoma yellow ventrally (except anterior part of mesopleuron), dorsally and laterally with large black parts and white spots: black—central transverse spot on pronotum, mesonotum (except lateral parts), spots on axillae, mesopleuron posterodorsaly; propodeum predominantly black, propodeal enclosure with yellow lateral spots at base and apical spot. Legs yellow with white parts and darkened dorsal side on trochanters and femora, inner side of tibias. Veins of wings yellowish-brown. Metasoma ferruginous with ivory apical bands on terga 1–3 and lateral spots on tergum 4; tergum 6 whitish (except apex).
Male. Unknown.
Etymology. The species is named after Tulkin U. Rakhimov, lecturer at Karshi State University ( Uzbekistan), thanks to whose efforts expeditions to study Hymenoptera of Uzbekistan was possible.
Distribution. Uzbekistan.
