Abstract: Abacoproeces topcui sp. nov. (Araneae: Linyphiidae) is described based on male specimens from in Turkey. Four species, namely Araeoncus tauricus Gnelitsa, 2005; Erigonoplus globipes (L. Koch, 1872); Megalepthyphantes pseudocollinus Saaristo, 1997; and Styloctetor romanus (O. P.-Cambridge, 1872), belonging to this family are new records for the fauna of Turkey. Styloctetor Simon, 1884 has been recorded as a new for Turkey. Data on collected localities, distribution throughout the world, and genitalia figures of each species are presented.

Key words: Araneae, Linyphiidae, Turkey, new records

The family Abbreviations used in the text and in the figures are as Linyphiidae, commonly called the sheetweb , is a follows: cym: cymbium; cd: copulatory duct; cdo: copulatory large spider family comprising 589 genera and 4482 species duct opening; e: embolus; fd: fertilization duct; fm: femur; worldwide, of which 116 species of 64 genera are known in m: membrane; mt: metatarsus; pc: paracymbium; pt: Turkey, but it must be regarded as an insufficiently studied patella; tb: tibia; tba: tibial apophysis; tr: tarsus; sc: scapus; family. It has recently been given increased attention sp: spermatheca; st: subtegulum; rp: radical part; NUAM: in taxonomic and faunistic studies (Topçu et al., 2005; Arachnology Museum of Niğde University, Niğde, Turkey.

Palpus: Cymbium boat-shaped, paracymbium Diagnosis: Abacoproeces topcui sp. nov. is very closely 3-dimensional, nearly U-shaped and slender; angular at related to A. saltuum (L. Koch, 1872) from the Palearctic proximal end and more annular at distal end, embolus (cf. Wiehle, 1960: Figures 172–175; Heimer and Nentwig, tapered, bent at end, and covered with wide membranous 1991: Figure 361.1).

Province, Başyayla district, 27.VI.2007. Female: Unknown. Distribution: , Ukraine (Platnick, 2014). Etymology: The species is named in honor of the Erigonoplus globipes (L. Koch, 1872) (Figure 4) Turkish arachnologist Prof Dr Aydın Topçu. Material examined: Turkey: 1♀ (NUAM), Natural history and distribution: Abacoproeces topcui Kahramanmaraş Province, Deliosman village, 02.V.2007. sp. nov. inhabits the soil covering of a coniferous forest. Distribution: Palearctic (Platnick, 2014). Known from the type locality only.

Our results have added 4 new Distribution: , , (Platnick, 2014). records and a new species to the Turkish spider fauna; Styloctetor romanus (O.
