Ulidia sp. nr. apicalis Meigen

( Fig. 21 )

Material examined. ISRAEL: Yerushalayim [Yerusalem], 12.vi.1940 (1♀)( TAUI).

Description. Head ( Fig. 21 ): Structure: 1.29 times as high as long. Frons of same width posteriorly and at lunule level, 1.23 times as wide as long, smooth, medially concave, with posterolateral protrusion. Eye 1.5 times as high as long. Gena 0.46 times as high as eye, posteriorly corrugated. Fronto-orbital plate at antenna insertion level 0.17 times as long as eye. Color and vestiture: Head mostly reddish-brown. Frons posteriorly black. Orbit with fine white microtrichose line with anterolateral triangular widening. First flagellomere orange, slightly silvery microtrichose. Arista with microscopic rays. Face, postgena, occiput and ocellar triangle reddish-black. Setae and setulae: Postocellar seta 0.85 times as long as ocellar seta; 2 orbital setae, each 0.88–0.91 times as long as ocellar seta. Frons densely long setulose, setulae 0.7–0.8 times as long as ocellar seta. Vibrissal angle and parafacial dorsally with long and thin setulae. Gena and postgena long setulose, longest setulae as long as orbital setae. Palpus with long black setulae; labellum with mixed black and white long setulae.

Thorax: Color and vestiture: Black, densely shagreened. Setae and setulae: 2 supra-alar, 1 dorsocentral, 1 acrostichal, 1 anepisternal and 1 katepisternal setae present. Postpronotal lobe, scutum and scutellum densely setulose, setulae 0.4–0.5 times as long as major setae; anepisternum and katepisternum long setulose, setulae 0.7– 0.8 times as long as major setae.

Legs: Mostly blackish-brown except midtarsus and hindtarsus with 1 basal tarsomere yellowish-brown.

Wing (too damaged to be illustrated): Pattern: Apical spot on wing covers apex of cell r1. Venation: Veins yellow basally, brown apically. Crossvein R-M aligned slightly apical to apex of vein R1. Vein Cu2 ratio 1.33. Calypteres yellow. Halter base and stem brown, knob yellow.

Abdomen: Mostly subshiny black except syntergite 1+2 basally inconspicuously white microtrichose; tergites shagreened and setulose.

Male terminalia: Unavailable.

Female terminalia: not examined.

Measurements (mm): Body length 5.24.

Diagnosis. This species greatly resembles U. apicalis Meigen , differeng from it in the median depression on orbit (orbit without median depression in U. apicalis ), and in the apical spot on the wing, which covers the apex of cell r1 (covers the apex of cells r1, r2+3 and partially r4+ 5 in U. apicalis ).

Comments. Although this species is clearly different morphologically from all congeners, due to the poor condition of the single available specimen it is not named here. This description is postponed until additional specimens become available.
