Tergites with black setulae and in marginal part with small white setae and tergite 5 with long brownish black setae ( Fig. 17 View FIGURES 13 – 18 ). Epandrium oval ( Figs. 22–23 View FIGURES 19 – 26 ); glans moderately long and mostly membranous ( Fig. 24 View FIGURES 19 – 26 ) Ejaculatory apodeme as in Fig. 26 View FIGURES 19 – 26 .

Oviscape shining black, yellow in lateral. All setae and setulae dark brown except setulae on tergite 1 ( Fig. 18 View FIGURES 13 – 18 ). Aculeus brown, 4 times as long as wide, with one pair of small preapical steps ( Figs. 19–20 View FIGURES 19 – 26 ). Eversible membrane as in Fig. 21 View FIGURES 19 – 26 . Spermathecae papillose, teardrop shaped ( Fig. 25 View FIGURES 19 – 26 ); round with narrowed neck.

Measurements. Female. Body length 4–4.5 mm, wing length 3.75–4.4 mm, aculeus length 1–1.25mm; Male. Body length 3.25–4.25 mm, wing length 3.25–4.5 mm.

Etymology. The new species is named in honour of Arezoo Najarpoor, who was one of the first collectors of this species.

Host plant. Unknown. The flies were swept from Helichrysum arenarium (L.) Moench, which is a possible host plant.

Discussion. The overlap between diversity of two species of Heringina lies in the North-Eastern Iran and Turkey, where both species live sympatrically, and sometimes in the same habitat. Its distribution in the Baltic part of Europe seems to be a result of a very late, almost certainly of postglacial, Neogene time. It is believed very rare or extinct at the edge of its historic distribution in Czech Republic and The Netherlands, and has not been recorded in Southwest Europe. Its possible host plant genus, Helichrysum Mill. 1754 , with almost 600 species, occurring mostly in Africa (especially in mainland Southern Africa), Madagascar, Southern Asia and Australia, belongs in the tribe Gnaphalieae (family Asteraceae ). Flower heads of the plants of that tribe are commonly infested by numerous species of another genus of the Tephritini , Actinoptera , which has it centre of diversity in Western and Southern Africa, and is less diverse in Mediterranean Europe, Southern Asia and Australia. Heringina is another genus certainly associated with Helichrysum , but its close relatives in the Afrotropical Region are not known so far. Afrotropical Multireticula perspicillata (Bezzi 1924) , which is near the base of the phylogeny of the Tephritis group and known to be reared from terminal galls on Helichrysum (see Merz 1999), has a broad, round wing, radiate pattern and four hyaline spots beyond pterostigma in r1 similar to Heringina spp. Its wing pattern and shape strongly resembles that in H. arezoana sp. nov., but other characters (chaetotaxy, structure of male and female genitalia) neither support, nor contradict their close relationships. Multireticula perspicillata differs with H. arezoana in having many small hyaline spots in wing pattern, abdomen without shiny black tergites and with paired spots on tergites 3 to 5. Some undescribed species of Tephritis swept from Gnaphalieae plants are recognized in the collections by SVK. Possible relationships of Heringina with Multireticula and Tephritis need more detailed phylogenetic analysis, which is out of the scope of this study.
