Diagnosis. This species generally matches the characteristics of the Platystoma lugubre  species group ( Hennig, 1945) with the following exceptions: presence of 2–3 supra-alar setae, as opposed to 4; absence of setulae on the scutellum; black ground color of the postpronotum, as opposed to red (differs from all species in the group except P. lugubre corsicanum Séguy  ). This species was also compared with specimens of similar species, P. t e gu l a r u m Loew and P. gemmationis (Rondani)  , from which it differs by a much shorter ventral calypter.

Description. Head ( Figs. 12View FIGURES 8 – 18, 23View FIGURES 19 – 29): Color and vestiture: Head conspicuously pale to dark brown, with yellowish-brown areas. Frons microtrichose mostly medially, at orbits and around bases of orbital setae, with 4 orange to brown patches delimited by inconspicuous transverse band of microtrichia at middle, and by median line of microtrichia. Ocellar triangle inconspicuously microtrichose, delimited by dense yellowish microtrichia. Lunule yellow to pale brown, with yellowish microtrichia, especially medially. Antenna: scape pale to dark brown, pedicel yellow to orange and 1st flagellomere dark brown, all microtrichose (not visible in certain angles). Face mostly blackish, except yellowish to brownish areas lateroventrally; dense gray microtrichia on most of dorsal part and medioventrally, leaving ventral 0.20–0.33 of antennal groove shiny black without microtrichia, and lateroventrally without microtrichia although matte. Clypeus mostly densely microtrichose, with small lateral shiny area (depending on angle of observation). Chaetotaxy: 2 (pairs) orbital setae and 1 (pair) postocellar seta present. Lunule setulose. Postgena and occiput with long yellowish setulae.

Thorax: Color and vestiture: Ground color black, with yellowish-gray microtrichia. Scutum with 3 or 5 microtrichose stripes. Postpronotal lobe ground color black. Scutellum medially and laterally microtrichose, with sublateral black spots, sometimes including round black spots around bases of setae. Subscutellum black, with grayish-yellow microtrichia, mostly laterally and near median. Pleura microtrichose as in genus. Chaetotaxy: Presutural supra-alar seta absent. 0–1 postsutural supra-alar seta present. Postpronotal lobe with yellowish setulae anteriorly and black setulae posteriorly. Anepisternum uniformly short setulose. Katepisternum with long curly yellowish-white to orange setulae. Ratios: Scutum: 0.81–0.95; postsutural supra-alar/intra-alar: 0.33–0.50; postalar/intra-alar: 0.46–1.09.

Legs: Color and vestiture: Leg type dark. Tarsi: fore and mid tarsi black, with yellow areas on proximal part of tarsomeres; hind metatarsus mostly yellowish, dorsoapically pale brown; 2nd tarsomere of hind tarsus yellowish ventrally and dorsally on proximal half. Other segments as fore and mid tarsi. Coxae anterodorsally microtrichose, posterodorasally shiny black. Chaetotaxy: Coxae and trochanters with mixed yellow and blackish setae and setulae, posterodorsally bare. Femora dorsally with blackish and mostly short setulae, with long and thicker setulae distally. Fore femur ventrally with yellow and blackish setae and setulae. Mid and hind femora, ventrally with thin long yellowish setulae. Tarsi with short, mostly blackish setulae, with shorter orange-brown setulae ventrally. Hind metatarsus anteroventrally with row of predominantly thick black setulae, distinguished from rest of setulae and more conspicuous in male.

Wing ( Fig. 34View FIGURES 30 – 40): Pattern: Mostly rather pale brown, reticulate, with large hyaline spots along and near costa and mostly smaller spots arranged in 2 longitudinal rows in each of cells r2+3, br and r4+5. Combined area of hyaline spots subequal to combined area of pigmented pattern. Conspicuous, dark, transverse bands or large spots present as follows: 1 band extending from costa at cell co, over crossvein BM-Cu, ending in anterobasal corner of cell cu1; 2 spots extending from costa in proximal 0.5 of pterostigma, ending in posterior margin of cell r1 proximal 0.5; 1 band extending from distal edge of pterostigma, aligned with crossvein R-M, ending medially at cell dm, anterior to vein Cu1; 1 spot extending from posterior part of cell dm, in level between crossveins R-M and DM-Cu, ending near medial of posterior margin of cell cu1; 1 narrow band extending (more or less intermittently) from costa to posterodistal edge of cell cu1, aligned with crossvein DM-Cu; 3 somewhat oblique bands beyond level of crossvein DM-Cu, converging medially towards cell r4+5: Proximal two forming "X" shape; apical band C-shaped.

The holotype ( Fig. 97View FIGURES 95 – 100) is double-mounted (minutien pin and polyporus block), in excellent condition, and deposited in SMNHTAU. Most paratypes are deposited at SMNHTAU; some paratypes will be deposited at the museums listed in the Material and Methods section.

Distribution. Israel.

Distribution in Israel. Mt. Hermon, Golan Heights, Upper and Lower Galilee, Carmel Ridge, Jordan Valley, Yizre'el Valley, Samaria, Foothills of Judea and Judean Hills.

Adult activity in Israel. February to April.

Etymology. This species is named after Mrs Geula  Freidberg, the late mother of the junior co-author. It is a noun in apposition.

Comments. This is the largest species of Platystomatidae  found in Israel. The numerous specimens studied by us can be fairly equally divided into two size groups based on body length: 6.70–8.50 mm or 4.20–6.20 mm. Our prior assumption that these two size groups may represent two new species is not supported by any other morphological evidence. We have therefore chosen to base our description of the new species on the large specimens only and designated these as the type series. The small specimens are also recorded in the material examined section following the large specimens, although they are not designated as paratypes.

Adults were frequently collected on Silybum marianum  ( Asteraceae  ), Mandragora autumnalis  ( Solanaceae  ), Scandix pecten-veneris  , and Smyrnium olusatrum  (both Apiaceae  ).
