Kalama aridula ( Jakovlev, 1902) , sp. dist.

Dictyonota aridula Jakovlev, 1902: 66 .

V. Jakovlev (1902) described Dictyonota aridula from Eupatorium (southern Crimea, Ukraine). Kerzhner (in Kerzhner and Jaczewski, 1964) placed D. (Alcletha) aridula in synonymy with D. (Alcletha) tricornis (Schrank, 1801) and was followed by other authors (all nomenclature and taxonomic changes into the genus Dictyonota Curtis, 1827 and corresponding changes of K. tricornis and K. aridula systematic positions see: Péricart & Golub, 1996).

An examination of the extensive collections of ZISP including the lectotype female of K. aridula (designated by Golub, 1975), shows that some of the specimens from the arid territories of central and eastern Palearctic identified previously as K. tricornis , are actually to lectotype of K. aridula . K. tricornis and K. aridula are actually two sympatric forms: K. tricornis is widely distributed almost throughout the Palearctic Region and North America ( Péricart & Golub, 1996), whereas K. aridula inhabits some southern and eastern territories (see below) into the K. tricornis area. Therefore we restore K. aridula as a good species. The main stabile differences between these two species are in the location and shape of hard setae on antennal segment III; these differences are as follows:

1. Setae on antennal segment III rather dense, curved, and rather strongly inclined towards the apex of antenna, no longer or only slightly longer than the thickness of segment ( Figs. 12, 13 ). On average, slightly larger: 2.9–3.4 mm ........... K. tricornis

- Setae on antennal segment III rare, straight or almost straight, strongly erected, often almost perpendicular to the surface of antenna, no shorter than the thickness of segment ( Figs. 14, 15 ). On average, slightly smaller: 2.75–3.15 mm ...... K. aridula

General distribution. On the base of studied materials of ZISP collection the distribution of K. aridula is as follows: southern Ukraine (southern Crimea); southern Transbaikalia (Buryatia: Kyachta); Uzbekistan (Sherabad; Yakkabag, south of Samarkand); Tajikistan (near Dushanbe); Mongolia. All these territories are indicated for the first time.
