Remarks.

The species is distributed in south Kazakhstan and northwestern Kyrgyzstan (Toropov and Milko 2013). Three subspecies have been described to date: D. mystacinum mystacinum Ballion, 1878, D. mystacinum rufidens and D. mystacinum pumilio Plavilstshikov, 1951 (Danilevsky 2018a). This subspecies seems to be endemic to the southeastern slopes of the Syr-Dar Karatau Mountains, where it mainly inhabits sparse grasslands and fixed sands in clayey and stony piedmonts between 320 and 1150 m a.s.l. The larvae feed on the roots of various grass species, mainly on Festuca and Stipa . The imagines are active from the end of April to the end of May (Toropov and Milko 2013).

Only the remains of a single female were found in a habitat with Caragana shrubs near the shore of a salt lake.
