Abstract: Cortodera kiesenwetteri gusakovi ssp. n. is described from Mugodzhary Mountains in Kazakhstan. It differs from the closest well investigated C. k. subtruncata Pic, 1934 by poorly developed elytral pubescence and very short palpi.
A big number of Cortodera taxa in Kazakhstan is still in progress. The present season has already brought one more remarkable taxon described below.
Cortodera kiesenwetteri gusakovi ssp. n.
(Fig. 1)
Description. A single male available; body middle sized (similar to the smallest specimens of C. k. subtruncata), black with yellow elytra; apical palpal joints very short, maxillary palpi much shorter than in C. k. subtruncata, don't extend over mandible apices as always in C. k. subtruncata; temples well developed; antennae relatively thin, black with slightly lightened distal half, reaching to about apical elytral fourth; 2nd antennal joint a little longer than wide; 3rd joint a little shorter than 1st and much longer than 4th; 5 th, 6th and 7th joints about equal in length and each much longer than 1st; prothorax strongly transverse, about 1.3 times shorter than basal width, with distinct lateral swellings; pronotum with wide central glabrous, shining area, typical for the species; with only erect setae, which are very long, that is also typical for the species; pronotal punctation moderately dense, scattered near middle; elytra yellow, slightly darkened near scutellum, with sides strongly tapering posteriorly, slightly narrowed near middle, about 2.2 times longer
than wide; elytral punctation moderately dense similar to certain specimens of C. k. subtruncata; elytral pubescence much shorter than in C. k. subtruncata, with long erect setae near humery only, while in C. k. subtruncata long erect setae are usually distributed to about elytral middle or further backwards; legs totally black; pygidium truncated, postpygidium with very small emargination; body length: 9.5mm, width: 2.8 mm.
Material. Holotype, male, Kazakhstan, central area of Mugodzhary Mountains, about 46km NE Emba-city, 418m, 49°0'60"N, 58°43'1"E, 18.05.2013, A.Gusakov leg. - preserved in Zoological Museum of Moscow Univesity.
Bionomy. The locality of the taxon (fig. 2) is a typical steppe landscape (which can not be identified as "stonny steppe" typical for C. k. subtruncata) without distinct specimens of big Centaurea, which is regarded (Danilevsky, 2010) as a main food plant (as Centaurea ruthenica) of Cortodera kiesenwetteri subtruncata. Remark. The new taxon is similar to C. k. subtruncata Pic, 1934 (described from "Samara" and known from Zhiguli Mountains and neighbor areas of Ulyanovsk Region - Danilevsky, 2010) because of same shape and color, though seems to be a little smaller; but strongly differs by shorter elytral pubescence and very short palpi. It differs from a single known specimen of the nominative subspecies C. k. kiesenwetteri Pic, 1898 (holotype - 9.8mm, described from "d'Astrakan" and preserved in Pic's collection in Paris) by same characters as C. k. subtruncata: more transverse prothorax and dense pronotal punctation.
Dedication. The taxon is dedicated by thankful author to Aleksey Gusakov (curator of beetle collection of Zoological Museum of Moscow University), who collected a single available specimen.
