FAZEKAS I.: Revision of the Hungarian Euchromius Guenée, 1845 species (Lepidoptera: Crambidae)

FAZEKAS I.: REVISION OF THE HUNGARIAN EUCHROMIUS SPECIES 241 Diagnosis: wingspan 14-19 mm. Frons with or without a small point, sides of labial palp creamy white at base. Tegulae with a dark patch in the middle. Forewing ground colour creamy white, densely suffused with ochreous to dark brown scales, anterior area yellow to brown-grey. Medial fascia double, arched or straight, inner fascia reduced or not, area adjacent to the nine or eight black terminal dots white. Similar species: Most like Euchromius anapiellus (Zeller, 1847) and E. vincuellus (Zeller, 1847). Male genitalia: processus of sacculus short, valvae with two dorsal processses, the processus inferior small. Aedeagus with large hook-shaped cornutus. Female genitalia: posterior part of ductus bursae very broad; bursa copulatrix elongated and very lightly sclerotized and signa absent. Biology and habitat in Hungary: The single generation flies from June to the end of August. According to literature, the larva lives on dry leaves of Hieracium, Picris and Scabiosa, also recorded to attack the roots and flower heads; August to June. So far, the larva has not been found in Hungary. The moth flies in a variety of habitats: colline and montane hay meadows, acid grasslands and heaths; closed rock grasslands; rock steppes; slope steppes; acid open rock grasslands; white oak scrub woodlands and loess steppe oak woodlands. Known habitats are from 100 m up to 690 m.

Distribution within Europe: Balearic Islands, Bosnia and Herzegovina (yet to be confirmed), Bulgaria, Crete, Croatia, France, Georgia, Greece, Hungary, Italy, Macedonia, Poland (doubtful), Romania, Russia South, Sardinia, Sicily, Slovakia, Spain and Ukraine (yet to be confirmed). Geographic range: Distribution outside Europe; Morocco, Israel, Palestine, Lebanon, Jordan, Syria, Iran, Iraq, Tadzhikistan. Known in Turkey up to 2200 m and in Iran up to 2000 m. The adults fly in very hot and dry localities, with sparse herbaceous vegetation with very few grasses. Notes: According to SLAMKA (2010) the species is more frequent in Hungary, but this not so. E. bellus rare and mostly very local in Hungary, and is unknown from many areas. According to our knowledge the strongest Hungarian populations live in Mátra Mountains near Gyöngyös town (Sár Hills). The habitat preferences of the local population: slope steppes and subcontinetal peri-Pannonic scrub. This latter vegetation is low deciduous scrub with Continental and sub-Mediterranean affinities of the Pannonic basin and neighbouring regions including the eastern Alpine periphery, the southern periphery of the Northwestern Carpathians, the Transylvanian plateau and the adjacent foothills and valleys of the Eastern and Southern Carpathians, the southern periphery of the
