Within Europe this species has so far only been recorded from the Canary Islands (Tenerife, Gran Canaria, La Palma) (Becker 1908, Cresson 1930) and Madeira (Stuke 2012). Despite these isolated records the species is widely distributed and probably not rare with records from Egypt (Becker 1903, El-Hawagry et al. 2018), Israel (Mathis &amp; Zatwarnicki 2004a), Jordan (material listed above), Oman (Mathis et al. 2017), Seychelles (Mathis &amp; Zatwarnicki 2003), United Arabian Emirates (Mathis et al. 2017), Taiwan (Cresson 1930) and the Philippines (Cresson 1930).</p><p>Biology.

Hyadina guttata belongs to the group that is characterised by (i) only inner vertical seta and (ii) scutellum velvet black laterally (as Fig. 7). Males are straightforward to recognise by the golden dusted face.Except for the black legged H. agostinhoi, H. guttata differs by the shining tergite 5 that has at least laterally no microtrichia beside the scattered long hairs (Fig. 14). Terminalia as Figs 20-22.</p><p>Distribution. Hyadina guttata is widely distributed in Europe and might be the most common Hyadina species. The only European distribution border is in the north with the northernmost records known so far from 66° N in Finland (GBIF 2023a). Outside Europe it is found in North Africa with records from Morocco (Vitte 1988, 1991) to Egypt (Hollmann-Schirrmacher 1998, El-Hawagry et al. 2018), from Turkey (Hollmann-Schirrmacher 1998, Popescu-Mirceni 2011), Israel (Mathis &amp; Zatwarnicki 2004a) and the Far East of Russia (Krivosheina 1986).</p><p>Biology. Hyadina guttata lives in a wide range of habitats as summarized by Bährmann (1995). He points out that H. guttata might be common on xerothermic meadows. At least regionally it prefers wetlands in the widest sense including for example wet meadows, forests, or fens. It can be classified as ubiquitous. Of course, it might have very special habitat requirements that occur in different habitats that are not known so far. Hyadina guttata has been recorded all through the year with a peak in April and May (personal observation) and a second peak in autumn (Bährmann 1995), is probably polyvoltine and might overwinter as adult fly. The Laboulbeniales Stigmatomyces spiralis Thaxter, 1901 is reported from H. guttata (Dainat &amp; Dainat 1973 as S. hyadinae Balazuc, 1974 as S. hyadinae Rossi, 1993).</p></div>	https://treatment.plazi.org/id/038487E3AB120B37FCD9FA61E374FB3C	Public Domain	No known copyright restrictions apply.

It has been recorded from the coast of the Dead Sea in Israel (Mathis &amp; Zatwarnicki 2004a), the Mediterranean Sea with records from Italy (Canzoneri &amp; Meneghini 1987, Canzoneri &amp; Vienna 1988b, 2000, Bertoli et al. 1992, Raffone 2009) France (Dainat &amp; Dainat 1973, Martinez 2002, this work) and Mallorca (Canzoneri &amp; Vienna 1988a, Canzoneri &amp; Rallo 1996, Ebejer et al. 2006) and along the North Sea coast in Suffolk, and Pool Harbour, Dorset in South England (Gibbs 2005; pers comm.). Additionally, it has been recorded from few inland salt places in Germany (Oldenberg 1923, Stuke 2023) and from inland places without salt habitats in Slovakia (Zatwarnicki 1996), Fès, Morocco (Vitte 1991), Park HaYarden, Israel (Mathis &amp; Zatwarnicki 2004a), and Volano, Italy (Canzoneri &amp; Meneghini 1983).</p><p>Biology. Hyadina pollinosa is a halophilous species and has been recorded mainly from coastal and inland wetlands that are under the influence of salt water. However, there are records mainly from its southern distribution where it can be found at freshwater wetlands. Adults are recorded from March to October. Dainat &amp; Dainat (1973) reported H. pollinosa to be infested with the Laboulbeniales Stigmatomyces spiralis Thaxter, 1901 .</p></div>	https://treatment.plazi.org/id/038487E3AB160B39FD33FA91E035FC48	Public Domain	No known copyright restrictions apply.

Hyadina rufipes is an easily recognised species with inner and outer vertical setae developed, basal flagellomere orange ventrally and scutellum with velvet black markings at lateral edges (as Fig. 7). Terminalia as Figs 32-34.</p><p>Distribution. Hyadina rufipes is quite common and widely distributed over Europe with records from the Canary Islands (Becker 1908 as nitida) to the Republic of Mordovia, Russia (MacGowan et al. 2021). Records from Morocco (Vitte 1991 as nitida) and southern Portugal (Stuke et al. 2023) indicate that there is no southern distribution border within Europe. However, H. rufipes is not recorded from Spain so far (Zatwarnicki 2002), only once recorded from Portugal and not recorded in Italy south of Veneto (Canzoneri &amp; Vienna 2000). Most northern records of H. rufipes are from Finland at 68°N (GBIF 2023b). Outside from Europe H. rufipes is reported from Morocco (Vitte 1991 as nitida) and Russia Far East (Krivosheina 1986) only.</p><p>Biology. Hyadina rufipes can be found in all kinds of wetlands including salt influenced places, densely vegetated or bare margins of rivers or lakes, wet meadows, forests, or fens. Reasons for its occurrence or none occurrences at specific places are unknown and might be caused by specific bacteria in microhabitats we do not understand so far. Adults of H. rufipes occur from March to November with peaks in May and August. The species is polyvoltine and might overwinter as adult.</p></div>	https://treatment.plazi.org/id/038487E3AB180B39FF3FFC6AE2D2FD60	Public Domain	No known copyright restrictions apply.

It might be confused only with similar Nostima picta (Fallén, 1813) that also has a completely velvet black scutellum. However, N. picta has an arista with long rays (short in H. scutellata), obvious sublateral grey striped on the scutum (no sublateral stripes in H. scutellata), 2 obvious dorsocentrale seta (1 dorsocentral seta in H. scutellata), a densely dusted frons (shining to subshining in H. scutellata) and obvious long ommatrichia (inconspicious ommatrichia in H. scutellata). Terminalia as Figs 36-38.</p><p>Distribution. Hyadina scutellata is widely distributed but records are rare and scattered.Surprisingly there are no records from France nor the Iberian Peninsula and the records from Ireland (Haliday 1839) and Britain (Drake 2007) mark the western distribution. Eastwards H. scutellata reaches to Talmenka at 83°E (Zatwarnicki 1996). It has so far not been recorded in South Europe and the record from Georgia is the most southern location at 41° N. There are no records from Norway nor Sweden and the most northern findings are from Finland at 65° N (material listed above).</p><p>Biology. Hyadina scutellata is a species of freshwater wetlands and has probably a preference for margins of rivers and streams. Adults are recorded from January (Papp 2001) and March to September. This species is polyvoltine and probably overwinters as adult. At least in Germany this species has become rare with the last known record from 1994 (Zatwarnicki &amp; Hollmann-Schirrmacher 1997).</p></div>	https://treatment.plazi.org/id/038487E3AB180B3BFD2FFD71E366FE0A	Public Domain	No known copyright restrictions apply.

It is the only species of this group without white patches before and behind dm-cu. However, these white patches can easily be overlooked in other species and therefore other characters should be considered, especially that tergite 5 is all over covered with microtrichia and additionally longer setulae (Fig. 15). Terminalia as Figs 40-42.</p><p>Distribution. Hyadina vernalis is a quite common species and widely distributed in Europe. It is recently recorded from Portugal (Stuke et al. 2023 as H. humeralis auct.), occurs in Calabria, Italy (Canzoneri &amp; Vienna 2000 as H. humeralis auct.) and Georgia (material listed above). In Finland it has been found up to 66° N (material listed above). Lack of records in larger areas like Spain, parts of the Balkan or western Scandinavia are very probably due to the absence of collecting activities. The only record of H. vernalis outside of Europe is from the Kuril Islands (“Kunaschir, Sernawodsk”, Dahl 1968 as H. humeralis auct.) and should be checked carefully.</p><p>Biology. Hyadina vernalis inhabits different kinds of wetlands including wet meadows, salty places, margins of rivers, ditches, streams or lakes. Adults of H. vernalis were found all year round, the species is very probably polyvoltine and might overwinter as adult. The Laboulbeniales Stigmatomyces spiralis Thaxter, 1901 is reported at H. vernalis (Rossi 1993 as H. humeralis auct.).</p></div>	https://treatment.plazi.org/id/038487E3AB1A0B3BFF46FDA8E218FE26	Public Domain	No known copyright restrictions apply.

This species is easily characterised by the very short R 2+3 (Fig. 13) and the unique colouration of the face with velvet black patches at the gena (Fig. 3). Terminalia are illustrated in Clausen (1984).</p><p>Distribution. So far there are European records from Czech Republic (Zatwarnicki 1996), Denmark (Zatwarnicki 1991 misidentified as nigricornis), Germany (Stuke 2023), Hungary (Zatwarnicki 1991 misidentified as nigricornis) and Sweden (Zatwarnicki 1991 misidentified as nigricornis). Beside the European records this Holarctic species is reported from Nova Scotia and Ontario (Clausen 1984).</p><p>Biology. Hyadina vockerothi occurs in a brachypterous form and the Nearctic type material has been caught in “mouse run among Carex ” (Clausen 1984). Adults have been recorded in April, June and July in a damp birch wood and at a densely vegetated lake shore.</p></div>	https://treatment.plazi.org/id/038487E3AB1A0B3BFD2CFDB3E5C6FB5B	Public Domain	No known copyright restrictions apply.
