E-Mail: rezac@vurv.czAlthough the family Oonopidae includes 487 described species worldwide (PLATNICK 2007), little attention has been paid to the faunistics and taxonomy of these spiders. Records from Europe are scarce, concern only a few species and – in most cases – only a few specimens were collected. In Cen-tral Europe seven species; namely Ischnothyreus velox Jackson, 1908, Oonops domesticus Dalmas, 1916, O. pulcher Templeton, 1835, Orchestina pavesii (Simon, 1873), Silhouettella loricatula (Roewer, 1942), Tapi-nesthis inermis (Simon, 1882) and Triaeris stenaspis Simon, 1891 (BLICK et al. 2004) have been recorded so far. All these species may occur in the Czech Republic, nevertheless none of them has been un-equivocally recorded here until now. A single record of O. domesticus (BUCHAR & RŮŽIČKA 2002) is incorrect as this specimen was redetermined as T. inermis during this study.Tapinesthis inermis  (Simon, 1882)Oonops domesticus Dalmas, 1916: ŠMAHA (1976) and subsequently ŠMAHA (1981), BUCHAR (1995), BUCHAR et al. (1995), BUCHAR & KŮRKA (2001), BUCHAR & RŮŽIČKA (2002), BLICK et al. (2004); misidentifica-tion.     This species can be distinguished from the other oonopid species occurring in Central Europe by an abdomen without a scutum and the tibia of leg I without ventral spines (Figs 1-3). See KRAUS (1967) for a detailed description.Distribution: T. inermis is the only species known in the genus and occurs in the northern hemisphere. In Europe it was found in the Netherlands (VAN HELSDINGEN 2003), Switzerland, Germany, Aus-tria (BLICK et al. 2004), Belgium (VANUYTVEN 2006), Bulgaria (LAZAROV et al. 2001), southern Europe (HEIMER & NENTWIG 1991) and has been introduced to the USA (PLATNICK 2007). In Europe the species mostly occurs synanthropi-cally (HEIMER & NENTWIG 1991), although it was also collected in natural habitats (KRAUS 1967, VAN HELSDINGEN 2003). It is thus possible that T. inermis is hemisynanthropic in larger cities (like Antwerp), where the general outdoor temperature is higher than in the countryside. Several specimens were found in dense ivy and close litter in more locations within the city of Antwerp (VAN KEER et al. 2006). All records for the Czech Republic (Fig. 9) come from indoors.Material: Brewery, Praha 5-Smíchov (50° 04' 29" N, 14 °22' 55" E), 9 April 1964, 1 , leg. E. Valešová-Žďárková, det. as juv.

Jäger, collec-tion of Research Institute and Natural History Museum Senckenberg, Frankfurt am Main (SMF).Triaeris stenaspis  Simon, 1891This species can be distinguished from the other oonopids occurring in Central Europe by the pre-sence of two scuta on the opisthosoma, the dorsal scutum covering less than 3/4 of the abdominal length and much larger than the ventral scutum (Figs 4-8). The male of this species has never been found. KOPONEN (1997) suggested that this species Arachnol.

See MILLER & ŽITŇANSKÁ (1976) for a detailed description.Distribution: The genus Triaeris contains 18 spe-cies occurring solely in the tropics. Of these only T. stenaspis has been introduced into Europe. This species was first described from the Caribbean is-land of St. Vincent (SIMON 1891) and according to PLATNICK (2007) it occurs from USA to Venezuela and in the West Indies. In Europe the species has been recorded from Great Britain, France, Belgium (HEIMER & NENTWIG 1991), Slovakia (MILLER & ŽITŇANSKÁ 1976) and Finland (KOPONEN 1997). The record from Belgium was later rejected (BLICK et al. 2004, VANUYTVEN 2006) because it was an unconfirmed verbal communication (Vanuytven in litt. 2007). In Europe the species has always been found within heated greenhouses. In the Czech Republic it was so far collected only from one place (Fig. 9), but it is expected to be present also in other cities.Material: Greenhouse, Botanical Garden of the Ma-saryk University, Brno (49° 12' 17" N, 16° 35' 47" E), 18 October 2006, 1 , leg.
