Occurrence of groundhopper Tetrix bolivari (Orthoptera: Tetrigidae)
in the Czech Republic and Slovakia
Jaroslav Holu5a & Petr Kodirrek
Abstract
The occunence of Tetix bolivari in the Czech Republic and Slovakia is pre-
sented and discussed. This groundhopper is a very rare species on the northern
edge of its range there. We confirm the present occurrence in the southern terri-
tories of the both republics. All published as well as new data of the occunence
of Tetix bolivari in the former Czechoslovakia are presented in the map.
Introduction
Tetix bolivai Saulcy, 1901 (Fig. 1,2) is a hygrophilous (ripicolous and geophi-
lous) (lrucntsH & KOHLER 1998) subpontic-mediterranean species with a disjunc-
tive area (DEVRTESE 1996). ln the tenitory of the former Czechoslovakia firstly
Mnnnru (1956) mentioned its occurrence but without the name of any locality.
Celcnnru (1963, 1985) recorded particular localities. The specimens were found
at the end of the 4O-ties and the beginning of the SO-ties. According to the author
(Ce.lcHnr.r 1963) Iefnx bolivari occurs sporadically throughout the whole south
Slovakia and south-east Moravia (Czech Republic).
During the ast fifty years Tetix bolivai was not recorded from the Czech Repub-
f
lic. CHL,corx (1995) characterised this species as vulnerable in the territory of
Pdlava Biosphere Reserve but he does not know any other data besides locali-
ties published by CelcnnN (1963) (all known localities in the Czech Republic are
situated in this reserve). Due to dramatic changes in south Moravian landscape
(disappearing of wetlands and flooded areas in large scale) we supposed that
this species had become extinct in the Czech Republic (KoCAREK et al. 1999).
We confirmed the occurrence of Tetix bolivai in the Czech Republic and Slova-
kia. Bellow we show these findings as well as all published data. All the data are
presented in a grid map (Fig. 3) (for the code of map field see ZelrruY (1972) and
PRururueR & Mixn (1996)).
The number of collected males and females are presented in the following form:
number of males / number of females.

At the village of Piim6tice this species lives around a small lake (area of
2 are) in the former kaolin-pit in now flooded. The banks are scarcely
covered mainly by Phragmites communisand Juncus sp. In the period
of 02.08.-06.08.1999 only nymphs were obseryed while on 08.05.2000
only adults were collected. 19.08.2000 we found a few adults as well as
nymhs. After the intensive research it seems that the population counted
only several dozens of specimens.

Discussion
eercnnru (1963) characterised Tetix bolivai as the species with sporadic occur-
rence. Only a few specimens were found in all mentioned localities (CelcHnru
1963). A possible reason of this is that the majority of specimens were collected
in July or August when the nymphs dominated in the population. On the other
hand it is incredible that this species has not been recorded so far in Hungary
(RAcz 1998) as well as Tetix ceperoi known from south-western Slovakia
(HoLUSA & Cnuorr 1998). According to published data (MARSHALL & HAES 1990,
BELLMANN 1985, Hor-uSA & CHLADEK 1998) it seems that Tetix ceperoi prefers
mainfy sandy places (or other good drainage ground) while lefni bolivai occurrs
on loamy or even clayey places (locality of Piim6tice).
In the territory of the Czech Republic and Slovakia Tetix bolivai is a very rare
species with polydisjunclive area (Fig. 3). All known localities are located in the
tenitory of panonic subprovince but the locality of Piimritice is on the northem
edge of this subprovince (Culer et al. 1996). The future existence of the popula-
tion in the Czech Republic is unsure due to the natural succession there. In Slo-
(U vakia our data confirmed the occunence in southern areas.

Erde des Lavendel-strauchs. Von den vier Heuschrecken uberlebten drei riere
bis Ende September. Bis zu diesem Zeitpunkt konnten trotz des hohen Tempera-
turniveaus der Mainzer Innenstadt (STADT Mnrruz 1989) die Tiere die Entwicklung
nicht vollenden. Sie erreichten nur das vierte Larvenstadium.
In dem vollstdndig versiegelten Hinterhof mit einzelnen Topf-GrUnpflanzen hiel-
ten sich die Tlere die ganze Zeit nur auf den Topfpflanzen (oder in direkter Naihe)
auf. Als Hauptnahrung dienten Lavendel-Bliitler (Lavandula angustifotia), an
denen in groBem Umfang RandfraB festgestellt werden konnte.
Es stellt sich die Frage, ob bei gUnstigerer Exposition und geringerer lsolation
des Innenhofs eine vollstiindige Entwicklung bis zum lmago mdglich gewesen
wdre und sich aufgrund der xerothermen Verhdltnisse des Mainzer Beckens eine
kurzfristige Kleinpopulation hiitte entwickeln konnen (vgl. Mainzer Sand:
lNGRlscH 1987). Zumindest macht diese Beobachtung wiederum deutlich, dass
manche ungewohnliche Heuschreckenfunde vornehmlich auf anthropogene Ver-
schleppungen zurUckzufUhren sind, vor allem, wenn man die Dimension der
transeuropdischen Waren- und Bodentransporte betrachtet.
