Mecostethus parapleurus (Hagenbach, 1822)

Material examined. Moravia mer., Hrabĕtice-Travní Dvůr, 12.viii.2011, 1 M, R. Vlk leg. et det., P. Marhoul coll.; Vrbovec-Ječmeništĕ, 26.viii.2011, 1 M, P. Marhoul leg., det. et coll., 1 M, R. Vlk leg., det. et coll.

Seidl (1836) published an occurence of this species in Zadní (nowadays Horní) Šárka, and the record was cited by Krejčí (1896) and Haury & Nickerl (1905), but without citation of the specific locality. Given that its distribution in central Europe does not extend beyond the Pannonian district (Kaňuch et al. 2006), an occurrence in Bohemia seems unlikely even though it is a very efficient flier (Kaňuch et al. 2006).

By the year 2005, this species was missing in the CR. The species was re-discovered after 2005, and at present, numerous occurrences are known from the southeastern parts of Moravia, especially in the environs of Lanžhot and Sedlec near Mikulov (Holuša et al. 2007a; as noted earlier in this report).

Acryptera fusca (Pallas, 1773)

This species has been demonstrably found only several times in the area of the CR (Czižek 1905; Görtler 1944; Dobšík 1948; Holuša 2012). A. fusca is a chortogeobiontic, subxerophilous, stenotopic species (Rácz 2001) living on sunny hill sides, semiarid to arid grasslands, and alpine pastures of mountainous and subalpine regiones (Nadig 1986; Detzel 1998; Krištín 2000; Krištín & Hrúz 2005). Its ecological requirements are difficult to define (Nadig 1991).

Currently, there is probably no locality in the CR suitable for the occurrence of this species. The known localities are either covered with forests (Josefov Valley) or covered with continuous grass stands (Javorník, the Velká Javořina Mt., and the Pradėd Mt.). Other suitable localities (lowland to mountainous heaths) in the territory of the CR are small and isolated (Chytrý et al. 2010; AOPK 2011). The nearest area of occurrence is near the village of Šípkov in the Strážovské vrchy hills (Gavlas 1999), which is 45 km from the Velká Javořina Mt. This species is evaluated as regionally extinct (Holuša 2012).

Acryptera microptera (Fischer de Waldheim, 1833)

A stable population has been known only in a single locality in the CR (Pouzdřany Steppe-Kolby NNR). The abundance of A. microptera at this locality declined during the 20th century, and only a few specimens exist in the museums in the CR. At each of two other localities (Kobylí and the Kamenný vrch u Kurdėjova NR), only a single male has been found in the past. In several extensive surveys conducted in the CR between 1990 and 2008, A. microptera has not been detected, probably because the habitat is not longer suitable for this species. Based on these facts, it is necessary to categorize A. microptera as extinct in the CR (Holuša 2012).

Dociostaurus brevicollis (Eversmann, 1848)

Material examined. Moravia mer., Bzenec, 18.viii.1950, 1M, leg. O. Ginter, coll. MJVM, J. Holuša det.; Vojenské cviċištė Bzenec NM, 7.x.1995, 1F, 14.viii.1999, 1M, 3F, 18.vii.2006, J. Holuša observ.

The species has been documented from only four localities (Görtler 1946; Ginter 1971) in the CR; in the case of two of the localities, no data have been collected since the 1960s. It presently occurs at only one locality on the open sands in the environs of Bzenec, where its abundance is fluctuating between hundreds and thousands of individuals (own observations).

Omocestus petraeus (Brisout de Barneville, 1856)

Material examined. Moravia mer., Mohelno, Mohelenská hadcová step NNR, 24.viii.2004, 1 M, 10.viii.2006, 3 M, 2 F, P. Marhoul leg., det. et col.; 19.vii.2012, 1 M, 1 F, R. Vlk leg., det. et coll.

According to Obenberger (1926), this species was reported from Bohemia by Haury & Nickerl (1905) but we did not find the species in the list of Haury & Nickerl (1905). In the CR, its occurrence has been recently confirmed only at Mohelenská hadcová step NNR. Historically, it has also been known from some other localities in southern Moravia (Pálava, Pouzdřany, Kobylí) (Görtler 1946; Chládek 1985). Despite intensive surveys of those localities, it has not been recently confirmed there.

Omocestus rufipes (Zetterstedt, 1821)

This species was reported from Bohemia by Haury & Nickerl (1905) but without detail regarding the locality. The species has been reported from the area of Bohemia only several times (Obenberger 1926, Niedl 1966) and the nature of its occurrence in the CR is generally unknown. It occurs in Moravia on the boundaries of the Pannonian and Central European deciduous forest biogeographical provinces (Holuša 2003; Holuša et al. 2012a). Despite an intensive survey, it has not been found in the area of Bohemia, and so it must be evaluated as missing in Bohemia.

Stenobothrus eurasius Ma ř an, 1958

This species is known from only several isolated localities in the České středohoří Mts. and Házmburská tabule plateau (Mařan 1958; Holuša & Holuša 2002). The occurrence reported from Moravia (Miroslavské kopce NNM) (Chládek 2006) was not been confirmed by repeated intensive surveys. Altogether, only five individuals were observed there (Chládek 2006) but they represent aberrant individuals of Stenobothrus nigromaculatus (Herrich- Schaeffer 1840) based on our revision (Miroslav, Miroslavské kopce NNM, 23.vi.2005, 1 M, vii.2007, 1 M, F. Chládek leg., det. et coll., R. Vlk revid.).
