Two interesting weevil species were found in Southern Moravia in the Czech Republic. Bagous bagdatensis Pic, 1904 is recorded for the first time from the Czech Republic. Gymnetron rotundicolle Gyllenhal, 1838 was already reported from Bohemia and now it is given as a new species for Moravia. Veronica chamaedrys is reported as a newly discovered host plant of G. rotundicolle in the Czech Republic.

Entomofauna of southern Moravia is relativelly well know, as it is the most popular area in the Czech Republic for entomologists. Despite that we found two weevil species previously not known from this area.
Czech Republic, Moravia mer.: Břeclav env., Pohansko (7267)* (GPS: 48°43'30.1"N, 16°53'43.5"E), 155 m, a drying ditch covered by vegetation of macrophyta species, 5.viii.2012, 8 ex., J. Krátký lgt., det. et coll.; 6 ex., M. Putz lgt., det. et coll.; 5 ex., F. Trnka lgt., det. et coll. All Moravian specimens were collected when activated by sunshine at the surface of mud covered with Lemna sp. and Ceratophyllum demersum. [Fig. W82.02]. A Central and Eastern Mediterranean species which is distributed from Sardinia, Italy, eastern Slovakia, Hungary, Romania, Balkan peninsula and Anatolia to the Middle East, Caucasus, Iraq and Iran [East-Curculio Team 2011]. This recently discovered locality is probably the northernmost location of the species in Europe. The host plant is unknown. New species for the Czech Republic.
Czech Republic, Moravia mer.: Ivančice env., Hlinek hill (6964)* (GPS: 49°5'42.7"N, 16°20'39.7"E), 260 m, 20.iv.2011, 2 ex.; iv.2012, 1 ex.; Biskoupky (6963)* (GPS: 49°5'46"N, 16°16'53"E), 263m, 30.iv.2012, 1 ex.; Sedlec env., Nesyt pond (7266)* (GPS: 48°46'31"N, 16°42'06"E), 173m, 1.v.2012, all D. Čudan lgt., det. et coll.; Dukovany env., Dukovanský mlýn Nature Reserve (6863)* (GPS: 49°5'44.305"N, 16°11'54.874"E), 320 m, 1.v.2012, 1 ex., J. Krátký lgt., det. et coll.
This species is originally known from the Ukraine, southern Russia, Bulgaria, Turkey, Georgia, Armenia, Iran, Turkmenistan, Uzbekistan and Kazakhstan [Caldara 2008]. In recent years it unexpectedly emerged in Central and Western Europe, thousands of kilometers from the original site. The way of its spread is unknown, but probably it was introduced with transport or plant seedlings and quickly acclimatized [Caldara 2008]. Yet it has been reported from the Czech Republic (Bohemia) [Strejček 2007] and Italy (Veneto) [Caldara 2008]. Recently, we found it also in the eastern half of the Czech Republic, in Southern Moravia. Adults of G. rotundicolle were collected in the Czech Republic (environment of Hradec Králové, J. Krátký lgt.) by sweeping from Veronica chamaedrys [Fig. W82.04], which will be here probably also its host plant. It is the first record of a host plant for Gymnetron rotundicolle.
New species for Moravia.
