Abstract. A determination key to the Central European paper wasps (Polistinae Polistes Latreille, 1802 eight species) and social wasps (Vespinae 11 species:Vespa Linnaeus, 1758 one species, Vespula Thomson, 1869 four species,Doli-chovespula Rohwer, 1916 six species) is given. Distribution and biotope re-
quirements of all species in the Czech Republic and Slovakia are briefly men-tioned. All social wasps occur more or less regularly in both countries. Four paperwasps are relatively common but four other species (Polistes atrimandibularisZimmermann, 1930, P. sulciferZimmermann, 1930, P. associus Kohl, 1898, andP. gallicus (Linnaeus, 1767)) are very rare with the Czech Republic and/or Slova-kia at the northern edge of their range.

Introduction
According to present knowledge, social and paper wasps form two subfamilies (Vespinae,Polistinae) of Hymenoptera: Aculeata: Vespidae. Mason wasps (Eumeninae) and pollen wasps(Masarinae), ranked as different families in the past, are now considered as subfamilies with-in the Vespidae as well (e.g. CARPENTER 1982). The last (and the only) usable key to the paperand social wasps of the Czech Republic (BOUEK & USTERA 1956) is 50 years old. Regional,European, Palaearctic and world keys to the social and paper wasps have been published inrecent decades (e.g., GUIGLIA 1972, ECK 1984, ARCHER 1989, STARR & LUCHETTI 1993, MAUSS& TREIBER 1994, PEKKARINEN 1995), but they have some limitations for Central European

vespidologists. This work aims to make new information readily available to a broad spec-trum of entomologists, and to provide a straightforward identification key to the Vespidsfound in the Czech Republic and Slovakia.
This key is based on MAUSS & TREIBER (1994) with additional species which do not occurin Germany. Several characters have been omitted and several others added; the structure ofthe key has been altered in a number of places. The main additions concern Polistes Latreille,1802, with information taken from STARR & LUCHETTI (1993) and GUIGLIA (1972). Severalcharacters typical ofDolichovespula Rohwer, 1916, were adopted from ECK (1984), ARCHER(1989), and PEKKARINEN (1995). The nomenclature is adopted from CARPENTER (1996) andCARPENTER & KOJIMA (1997).
The key is usable for Central Europe, and only the most typical markings have been includ-ed in the key. As the variability of some markings is very high, further information is listed in
the species accounts, including notes on similar species.
Key to the paper wasps (Polistinae)
Paper wasps can be easily distinguished from social wasps by having tergum 1 convergent.

Parasitic species. One old record is known from southern Slovakia (BOUEK & USTERA1956). The species was regularly found in the Mursk Planina National Park (SMETANA2004). The only record from the Czech Republic was not published yet (L. Dvok, own data).
Polistes bischoffi Weyrauch, 1937
It is very difficult to separate females of this species from P. biglumis. Other species differby short erect hairs on mesoscutum. Males are similar to P. gallicus, which has clypeus con-vergent below and temples strongly convergent behind eyes, but both species differ by hairson mesoscutum and colouring of antennae P. bischoffi has antennae distinctly darkenedabove, while P. gallicus has antennae orange beyond segment 3.
The newest member for the fauna of both countries, which is known from the southern
parts of the Czech Republic and from northwest and west Slovakia (see DVOK et al. 2006for summary).
Polistes biglumis (Linnaeus, 1758)
Females are very similar to P. bischoffi. The species is extremely variable in colour, and theyellow colour is often considerably reduced. Males are most similar to P. dominulus, whichhas antennae orange beyond segment 3.
Common species at higher altitudes in the past, but slightly decreasing at present.
Polistes dominulus (Christ, 1791)= P. gallicus auct. nec Linnaeus, 1767
Females clearly distinct in having antennae orange beyond segment 3, a character sharedwith P. gallicus. Polistes gallicus differs in having yellow mandibles, black genae and blacklast sternum (in Central European populations), while P. dominulus has black mandibles,yellow genae and yellow on the majority of last sternum. Most Central European specimenshave clypeus completely yellow, exceptionally with black spot or transverse band; the blackmark is more often found towards south. Males are similar to P. biglumis in having parallel-sided clypeus without longitudinal ridges, but P. biglumis has antennae blackened above (al-most black) and mesoscutum with long erect hairs.
Southern element occurring in southernmost parts of Central Europe in the past. Afterspreading in the last decades, it is the commonest paper wasp of the Czech Republic andSlovakia at present, and it occurs from the lowest to the highest altitudes.
Polistes gallicus (Linnaeus, 1767)= P. foederatus Kohl, 1898
Females are similar to P. dominulus by having antennae orange beyond segment 3. For
differences separating these two species see above. Males are similar to P. bischoffi, whichhas clypeus convergent below and temples strongly convergent behind eyes, but both species

differ by colouring of antennae P. gallicus has antennae orange beyond segment 3, while P.bischoffi has antennae distinctly darkened above.
Taxonomic status of this species requires revision. Specimens from southern and south-eastern Slovakia belong to a species inhabiting the whole Pannonian plain (A. Cetkovi, un-publ. data). Thermophilous and halophilous species.
Polistes nimphus (Christ, 1791)
Females differ from other species by having the following colour features: mandibles black,genae with yellow markings, antennae darkened above, and the last sternum black, sometimeswith small yellow apical spot. Clypeus usually with black transverse band. Males are recogn-isable by the parallel-sided clypeus with longitudinal ridges.
Relatively common species at lower altitudes.
Polistes associus Kohl, 1898
Females are very similar to P. nimphus. In P. associus the last sternum is usually reddish-brown with lighter apical spot. According to J. Gusenleitner (pers. comm.), Austrian popula-tions have the last sternum coloured similarly to P. nimphus and differ by reduced black stripeon clypeus. Males are similar to P. gallicus and P. bischoffi by having clypeus convergentbelow and temples convergent backwards, but only P. associus has longitudinal ridges onclypeus.
South-European species of lower altitudes, which occurs in Hungary and eastern Austria.The only published record from Slovakia was from an old museum collection (DVOK 2005).Not known from the Czech Republic.
Vespa crabro Linnaeus, 1758 Hornet
Practically unmistakeable species due to its large body size and tri-coloured (red-brown-yellow) tergum 1. Only the queen ofDolichovespula media is similar in body size and colourpatterns. Distance of ocellus to apical margin of head can clearly separate the species.
This species inhabits predominantly floodplain and xerophilous broadleaf forests and or-chards at lower altitudes. It is closely associated with parks and orchards at medium andhigher altitudes.
Vespula germanica (Fabricius, 1793) German Wasp
This species can be confused only with V. vulgaris. Colour characteristics partly usable forseparation from V. vulgaris are as follows: Clypeus with 1-3 black points. Yellow colour inocular sinus convex towards antennae (often connected in males with frontal spot). Genaeand temples completely yellow. Yellow lateral band on thorax widened in middle. Tergum 1
always with black rhombic spot.

DVOK & ROBERTS: Key to the paper and social wasps of Central Europe234
The commonest species in urban habitats. Inhabits open and often secondary biotopes.Very rarely found in forested areas and above 800 m a.s.l.
Vespula vulgaris (Linnaeus, 1758) Common Wasp
This species can be separated from the similar V. germanica by the key and followingfeatures: Clypeus mostly with black anchor-shaped spot, rarely with black colour reduced.Yellow colour in ocular sinus straight or concave towards antennae. Yellow genae and tem-ples most often with black spot, the yellow band often interrupted by black, rarely with smallblack spot on outer margin. Yellow lateral band on thorax not widened medially.
Ubiquitous and everywhere common. A little rarer than V. germanica in open habitats, butone of the most common species in forested areas. Inhabits also secondary spruce forests.
Vespula rufa (Linnaeus, 1758) Red Wasp
This species has red colour on terga 1 and 2 unlike its social parasite V. austriaca. Clypeusoften with black anchor-shaped marking.
Relatively common species in the Czech Republic and Slovakia. Distinctly prefers foreststands and inhabits dry coniferous forests too.
Vespula austriaca (Panzer, 1799) Cuckoo Wasp
Terga 1 and 2 without red colour (unlike its host V. rufa). Clypeus usually with a singleblack spot, occasionally with three spots.
Probably the commonest of the parasitic Vespine wasps and with the same habitat require-ments as its host.
Dolichovespula media (Retzius, 1783) Median Wasp
Unmistakeable species due to almost completely yellow ocular sinus a colour feature notshared by any other Central European species ofDolichovespula. Queens are very similar toworkers ofVespa crabro; both species can be separated by distance of ocelli to margin ofhead.
Probably the rarest social wasp excluding parasitic species. It sporadically occurs in thewhole territory of the Czech Republic and Slovakia from lowlands to mountains. A forestspecies.
Dolichovespula omissa (Bischoff, 1931)=D. ingrica (Birula, 1931)
Parasitic species ofD. sylvestris. Queens are similar toD. adulterina in having apically
pointed anterior angles of clypeus, butD. omissa has lower half of clypeus with dense andcoarse punctures. Special colour characteristic of queens are yellow bands on sterna 1-5 which

Red colour can be lost in some specimens, which can be problematic to separate from D.saxonica. Additional characters are: Clypeus with longitudinal black stripe regularly touchinglower margin. Postscutellum practically always without yellow spots. Males differ from D.saxonica by gonostipes, by only one visible tyloid on lower parts of antennal segments 9-12,and by black antennal scapus.
Boreoalpine species which rarely occurs at lower altitudes. Very common species in moun-tains and in larger forests; dominant in mountain peat-bogs.

Vosy a vosci (Vespinae, Polistinae) tvo dle nejnovjch poznatk 2 podeledi azenv rmci ahadlovch blanokdlch do eledi Vespidae. Jejich nejblimi pbuznmi jsoujzlivky (Eumeninae) a medovosy (Masarinae), kter dve tvoily samostatn eledi, zatmconyn se ad t jako podeledi do Vespidae (nap. CARPENTER 1982). Posledn a vlastn jedinpouiteln kl na urovn vosk a vos z zemesk republiky a Slovenska (BOUEK &
USTERA 1956) je 50 let star. Pestoe byly v poslednch letech publikovny kle regionln,evropsk, palearktick nebo i celosvtov na vosy i vosky (nap. GUIGLIA 1972, ECK 1984,ARCHER 1989, STARR & LUCHETTI 1993, MAUSS & TREIBER 1994, PEKKARINEN 1995), maj proStedoevropana jist limity. Jednak je to u nkterch kl pli velk mnostv zahrnovanchdruh, jednak jazykov rozttnost (francouztina, nmina, anglitina). Tento pedkldankl si klade za cl zaplnit vzniklou mezeru a zpstupnit nkter nov poznatky ohledndeterminace ir entomologick obci v anglickm i eskm jazyce. Zklad byl vypracovnpodle kle MAUSS & TREIBER (1994), ke ktermu byly pidny druhy neznm z Nmecka.Nkter znaky byly vyputny, jin naopak pidny, v mnoha mstech byla zmnna strukturakle. Hlavn doplky se tkaly zejmna rodu Polistes Latreille, 1802; ty byly excerpovny zprac STARR & LUCHETTI (1993), pop. GUIGLIA (1972). Nkter znaky k roduDolichovespulaRohwer, 1916 byly pevzaty z prac ECK (1984), ARCHER (1989) a PEKKARINEN (1995). Pouitnomenklatura je pevzata z prac CARPENTER (1996) pro vosky a CARPENTER & KOJIMA (1997)pro vosy.
