038DEA58FFB2FF90FE01F988C67BD986.taxon	materials_examined	A. dentigera Kulczynski, 1913 was found on and in tussocks of Carex elata in a small semi-open mesotrophic coastal marsh surrounded by alder trees. In pitfall traps one female and one juvenile were trapped (26 March - 5 Apr. 1991), one juvenile (14 May - 3 June 1991), one male (7 - 30 Nov. 1991) the top of tussocks. Two males were found in the middle of a tussock that was cut in small pieces (27 Oct. 1991). Agroeca dentigera has also been found previously at another locality on the coast of Scania. S. Almquist (pers. com.) found one female in a drift of Phragmites australis on a coastal pasture used by horses south of Klagshamn (55 ° 30 ' N 12 ° 55 ' E), 3 Sept. 1976. The female was found in the area between the pasture and a belt of Phragmites in sea water.	en	Jonsson, Lars J.

038DEA58FFB2FF90FE01F988C67BD986.taxon	distribution	Agroeca dentigera has been reported from a few places in Germany (BRAUN 1967, WUNDERLICH 1975, PLATEN et al. 1999), Belgium (JOCQUE 1977, JANSSEN 1991), Romania (OLTEAN 1973, STERGHIU 1985), Poland (KUPRYJANOWICZ 1997), the Netherlands (v. HELSDINGEN 1999), Wales (FELTON et al. 2004), Finland, Lithuania (KOPONEN et al. 2000, RELYS & DAPKUS 2002, RELYS et al. 2002), Belarus (MIKHAILOV pers. comm.), Ukraine (MIKHAILOV 1997) and in Russia (KULCZYNSKI 1913), eastwards to the Urals (Esyunin & Efimik 1996).	en	Jonsson, Lars J.

038DEA58FFB2FF90FE01F988C67BD986.taxon	discussion	The female originallydescribedby KULCZYNSKI, 1913, has later been figured by several arachnologists (Braun 1967, OLTEAN 1973, Jocque 1977, Sterghiu 1985, Roberts 1998 and Felton et al. 2004). The drawing ofthe heart-shaped epigyne by GRIMM (1986) and the copy in HEIMER & NENTWIG (1991) is somewhat atypical. The male has been figured by WUNDERLICH (1975), JOCQUÉ (1977), Roberts (1998) and Felton et al. (2004). Figs. 1 - 2 show the pedipalp of a male and figs. 3 - 6 the epigyne of females from Sweden. WUNDERLICH (1975) found A. dentigera in a marsh with Carex lasiocarpa surrounded by an alder fen. JOCQUÉ (1977) found it among heather, Calluna vulgaris, on dry ground near water and among the grass Molinia caerulea on wet ground. According to him A. dentigera needs " the vicinity of wet acid soils ”. It has also been reported from mosses of Sphagnum. (BRAUN 1967, STERGHIU 1985, JANSSEN 1991). In Romania it has been found in a floating belt of Phragmites in the Danube delta and in association with Sphagnum (OLTEAN 1973, STERGHIU 1985). The records in Finland and Lithuania are from peatbogs, both open and with pines (KOPONEN et al. 2001, RÉLYS et al. 2002). The report from Wales is from a somewhat different environment, from a hollow in a fixed sand dune with Ammophila arenaria dominant (FELTON et al. 2004). It seems that A. dentigera needs wet, thick heaps of vegetation, e. g. tussocks or mosses. It is obviously hygrophilous. Probably it spends the day in tussocks, mosses or other wet heaps and wanders, at least some ofthe time, on the surface during the night. The species is active in autumn and spring, but can also fall into pitfall traps during the winter. It is red-listed as vulnerable in Sweden (GÄRDENFORS 2005).	en	Jonsson, Lars J.

038DEA58FFB3FF93FA74FCADC2AAD2DB.taxon	discussion	Entelecara omissa was described by PICKARD - CAMBRIDGE (1902), but was named w ithout any detailed description as a nomen nudum two years earlier (PICKARD - CAMBRIDGE 1900). The first drawings of the male palp were published later (PICKARD - CAMBRIDGE 1903), although the drawing of the female's epigyne was of Entelecara errata (O. P. - Cambridge, 1913) (see PICKARD - CAMBRIDGE 1913). O. P. - Cambridge never made any drawings of the female of E. omissa.	en	Jonsson, Lars J.

038DEA58FFB3FF93FA74FCADC2AAD2DB.taxon	distribution	It has been reported from mesotrophic fens in England and from Ireland (RUSSEL-SMITH 2002), from a fen area in Belgium (DECLEER 1992), from fens in Poland (KUPRYJANOWICZ 1997), from Ukraine (K. Mikhailov pers. com.), from a reed swamp in the Czech Republic (BUCHAR & RUZICKA 2002), the Netherlands (van HELSDINGEN 1999) and from an ombrotrophic mire in Germany (SCHIKORA 1994) and also from two other localities in Germany (STAUDT 2004)	en	Jonsson, Lars J. (2005): Agroeca dentigera and Entelecara omissa (Araneae: Liocranidae, Linyphiidae), found in Sweden. Arachnologische Mitteilungen 29 (1): 49-52, DOI: 10.5431/aramit2908
038DEA58FFB3FF93FA74FCADC2AAD2DB.taxon	discussion	. The latter two records in STAUDT (2004) are probably misidentifications and need confirmation (Blick, pers. com.). In England the species is found among tussocks and litter, cut sedge, reed-beds and similar habitats at ground level in fens (RUSSEL-SMITH 2002). In the same fen in Lomma as Agroeca dentigera a female of Entelecara omissa was found (7 Nov. 1990). E. omissa has also been found at three different lakes near Stockholm as reported by TULLGREN (1955) as a new species: Entelecara depilata. By comparing the drawings and description by TULLGREN (1955) and by checking the types in the NRM in Stockholm with the drawings made by LOCKET & MILLIDGE (1953), Roberts (1987) and TAZOE (1993), it is obvious that Entelecara depilata Tullgren is a junior synonym of Entelecara omissa O. P. - Cambridge, new synonym. In Sweden two females of Entelecara depilata have also been reported from the open mire Knisa myr (ALMQUIST 1984). Those females have been checked and are E. omissa. Entelecara depilata has also been reported from Estonia (VlLBASTE 1987) and is probably also E. omissa. The syntypes of E. depilata in the NRM are small, total length approx. 1,5 mm, cephalothorax approx. 0,65 mm. They are rather dark, with yellowish legs bearing dark annulation on the coxae. They have trichobothria on metatarsus I-III, but no trichobothrium on leg IV. Anterior median eyes slightly larger than anterior lateral eyes (Tullgren, 1955; pers. obs.). Trichobothria on metatarsus I approx. 0,45. This is in accordance with the descriptions of Entelecara omissa by LOCKET & MlLLIDGE (1953) and ROBERTS (1987). Fig. 7 shows the drawing of the epigyne of E. depilata made by TULLGREN (1955) and fig. 8 shows the epigynes by ROBERTS (1987).	en	Jonsson, Lars J.
