A molecular phylogeny and revision of the genus Pyropteron Newman, 1832 (Lepidoptera, Sesiidae) reveals unexpected diversity and frequent hostplant switch as a driver of speciation Author Bartsch, Daniel daniel.bartsch@smns-bw.de Author Pühringer, Franz f.puehringer@sesiidae.net Author Milla, Liz liz.milla@csiro.au Author Lingenhöle, Arthur arthur.lingenhöle@gmx.de Author Kallies, Axel 0000-0002-3778-2187 axel.kallies@unimelb.edu.au text Zootaxa 2021 2021-05-18 4972 1 1 75 journal article 6247 10.11646/zootaxa.4972.1.1 cdd9688e-9a3f-4602-992e-1f8693caab9b 1175-5326 4771798 E78473FE-5662-409A-90C2-7C4912DC57E8 Pyropteron koshantschikovi ( Püngeler, 1914 ) ( Figs 160, 161 ) Chamaesphecia koshantschikovi Püngeler, 1914 : Deutsche Entomologische Zeitschrift Iris, 28: 54, pl. 3 Fig. 10 . Holotype : Uzbekistan , Syr-Daria , Baigacum (MFNB). This large species is poorly known; it has only been collected in a few places in Central Asia. Barcodes. P. cirgisa and P. koshantschikovi are situated more basally in the clade, perhaps suggesting a central Asian origin of this species group. P. koshantschikovi and P. umbrifera show an average distance of 6.4%. Biology and habitat. Similar to previous species, local in low lying salt steppe ( Špatenka et al. 1999 ). Limonium meyeri Boissier is reported as host plant by Špatenka et al. (1996) . The larva is feeding 2 years in the root. Distribution. Uzbekistan and eastern Kazakhstan ( Špatenka et al. 1999 ).
