Mitt.  10:32-33  Kurzmitteilungen  Basel, Dezember 1995 le  os KlIMES & Pavel SeZDECKA: Egaenus convexus -a new harvestman from the Czech Republic Egaenus convexus  -eine neue Weberknechtart  aus der  Tschechischen Republik The harvestmen fauna ofthe Czech Republic is relatively species-poor; so far 29 species have been found, of them 23 in Bohemia, the western part of the country, and 26 species in  Moravia, the eastern part of the Czech Republic (SILHAvY 1956,1981, MARTENS 1978). The last new species for the area of the Czech Republic (Leiobunum glabrum) was reported 14 years ago by SILHAvY (1981). After his death in 1984 little attention has been paid to the faunistics of harvestmen in the country. Here we are reporting the first finding of  Egaenus convexus (C. L. KOCH 1835) in the Czech Republic. It was recorded in the SE part of  the country, in the Bile Karpaty Mountains. E.  convexus is a SE-European species (MARTENS 1978). The nearest localities are in Slovakia from where the species has been reported rarely. The first record was by Kratochvflwho found it near  Bratislava (KRATOCHViL 1934). Later, findings from the neighbourhood of  Nitra (SILHA  vY 1956) and the KoVa90vske kopce Hills (SILHAvY 1969) were reported. In  the very beginning of the 20th century the name Egaenus tibialis C.L.KOCH (= E.  convexus (C.L.KOCH)) was used (with a question mark) in a report from the Czech Republic (Krkonose Mts., NOSEK 1900). This report has never been confirmed and is doubtful. In 1994 we caught 30 adults of E.  convexus in the National Nature Reserve Gertoryje, Bile Karpaty Mts., at an elevation of about 400 m. The species was caught in a mesic oak woodland with a rich herb layer and in a subxerothermic wooded meadow dominated by  Bromus erectus.  The specimens were caught in pitfall traps and by hand. The pitfall traps were placed on the site between 15th May and 26th October, 1994, and emptied monthly. All adults (10 males and  15 females) were caught between the beginning of may and the beginning of september, immatures were caught 32 from the end of  august to the middle of  october. The immatures overwinter and matu  re in the next spring. The same phenology of  th is species has been reported by WEISS (1975,1980,1984) and GRUBER in MARTENS (1978, p.308). The occurrence of the  Pannonian  species  E.  convexus  in  the  Bile Karpaty Mountains supports the view of a close connection between the biotas of SE Moravia and the Pannonian lowland (PODPERA 1951).
