Anarta Ochsenheimer, 1816 is a noctuid genus restricted to Palaearctic and Nearctic realms. The genus belongs to the tribe Hadenini of the subfamily Noctuinae (Fibiger et al. 2011; Zahiri et al. 2013) and comprises about 80 valid species subdivided into seven subgenera (Hacker 1998; Fibiger et al. 2011): Trichoclea Grote, 1883 (= Hadula Staudinger, 1889), Cardiestra Boursin, 1963, Ptochicestra Hacker, 1998, Aglossestra Hampson, 1905, Calocestra Beck, 1991, Pulchrohadula Hacker, 1998, and Anarta Ochsenheimer, 1816 (= Discestra Hampson, 1905). The group has been revised by Hacker (1998), who considered Anarta, Trichoclea, Hadula and Discestra as distinct genera, but subsequently Trichoclea, Hadula and Discestra have been synonymized with Anarta by Fibiger & Hacker (2005).
Anarta mirabilis Volynkin, 2014 has recently been described from West Mongolia and the south-eastern part of the Russian Altai Mountains (Volynkin & Ivanova 2014). Subsequently, in the course of the extensive studies of the Lepidoptera fauna of Kazakhstan, the species was found in a number of localities in the country. The present paper contains new data on the distribution of this poorly known species in Kazakhstan and data on its bionomics as well.
Material and methods
Abbreviations of the depositories used: CAV = research collection of Anton Volynkin (Leominster, United Kingdom); KNC = research collection of Kari Nupponen (Espoo, Finland); OPC = research collection of Oleg Pekarsky (Budapest, Hungary); PGC = research collection of Pavel Gorbunov (Yekaterinburg, Russia); SMC = research collection of Sergei Melyakh (Yekaterinburg, Russia); STP = research collection of Sergey Titov (Pavlodar, Kazakhstan); ZISP = Zoological Institute of Russian Academy of Sciences (St. Petersburg, Russia). Other abbreviations used in the illustrations: HT = holotype; PT = paratype.
Moths were collected using light traps based on 160W and 250W mercury bulbs, and 8W black light and actinic tubes. The genitalia were dissected and mounted in Euparal on microscope slides. The photographs of adults were taken using a Nikon D3100/AF-S camera equipped with a Nikkor, 18–55 mm lens while the genitalia were imaged using the same camera attached to a microscope with an LM-scope adapter. All photographs were processed using the Adobe Photoshop CC 2018 software. The distribution map was constructed using the online resource SimpleMappr (www.simplemappr.net).

Bionomics. The species was found in Kazakhstan in the middle and southern steppe sub-zones (Botanical geography… 2003). Anarta mirabilis is a local hemi-petrophilous species inhabiting petrophytic steppes and rocky steppe slopes (Figs 11–14). Only in one locality (Besoba Mt.), it was collected in the clayey desert steppe with minor rubble outcrops. Adults fly from late April to middle May and were collected together with such typical spring Lepidoptera as Orthosia spp., Shargacucullia spp., Cucullia inderiensis Herrich-Schäffer, 1856, Egira anatolica (Hering, 1933), Athaumasta spp., Simyra nervosa ([Denis & Schiffermüller], 1775), Anarta dianthi (Tauscher, 1809) (first generation), Anarta trifolii (Hufnagel, 1766) (first generation), Cerastis rubricosa ([Denis & Schiffermüller], 1775), Watsonarctia deserta (Bartel, 1902), Eudiaphora turensis (Erschoff, 1874), Saturnia pavonia (Linnaeus, 1758), Phyllodesma ambigua Staudinger, 1901, Lycia hirtaria (Clerck, 1759), Callophrys rubi (Linnaeus, 1758), etc. In the regions of the sympatric occurrence with the externally similar Anarta armata (Staudinger, 1888), the flight periods of the two species only partly overlap and A. armata usually gets on wing two or three weeks later than A. mirabilis. However, in East Kazakhstan (Karabastau and Arkaly Mts), specimens of both species in good condition were collected at the same nights. The preimaginal stages and the host plants are unknown.
Distribution. The species is known from Western Mongolia, south-eastern Russian Altai (Volynkin & Ivanova 2014), and Kazakhstan (Aktobe, Karaganda, Abai and East Kazakhstan Regions) (Fig. 15).
The senior author expresses his sincere thanks to Vitaly Radchenko (Pavlodar, Kazakhstan) for his help in organising the expedition in the Bektau-Ata Mountains. The senior and the third authors are grateful to Valery I. Volynkin (Biysk, Russia) for his help in organising the expedition in western Tarbagatai Mountains. The study of Sergey Titov, Petr Egorov and Ruslan Rakhimov was founded by the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan (Program No. OR11465437). The work by P. Y. Gorbunov was partly supported by the project of the Institute of Animal and Plant Ecology of the Russian Academy of Sciences “Interaction of natural and anthropogenic factors in formation of the diversity of plant and animal worlds of the Uralian Region”, FUWU-2022-0007. The study of Anton Volynkin had no foundation.
