Bu çalışmada, iki linyphiid türü olan Araeoncus altissimus Simon, 1884 ve Trichoncus auritus (L. Koch, 1869), Türkiye’den ilk kez rapor edilmiştir. Her iki tür de Kafkasya ve Avrupa’nın bazı bölgelerinden bilinmesine rağmen, şu ana kadar Türkiye’deki varlıkları bilinmemekteydi. Bu türlerin Bayburt ilinden tespit edilmesi, yalnızca bilinen dağılım alanlarındaki biyocoğrafik boşluğu doldurmakla kalmayıp, aynı zamanda örümcek çeşitliliğinin ortaya konmasında bölgesel faunistik çalışmaların önemini de vurgulamaktadır. Örnekler, Bayburt ilindeki üç farklı lokalitede taş altları ve kayalık habitatlardan penset ve el aspiratörü kullanılarak toplanmıştır. Örnekler stereomikroskop kullanılarak teşhis edilmiş ve dijital kamera ile fotoğraflanmıştır. Yeni kayıtlara ait morfolojik ve genital karakterlerin tanımları ve fotoğrafları verilmiştir.

In the present study, two linyphiid species, Araeoncus altissimus Simon, 1884 and Trichoncus auritus (L. Koch, 1869), are recorded for the first time from Türkiye. Although both species are known from certain areas in Europe and the Caucasus, their presence in Türkiye had not been previously known. The detection of these species in Bayburt Province not only fills a biogeographical gap in their known distribution ranges, but also underscores the importance of regional faunistic surveys in revealing spider diversity. The specimens were collected from beneath stones and rocky habitats at three different locations in Bayburt province using forceps and a hand aspirator. The specimens were identified using a stereomicroscope and photographed using a digital camera. Descriptions and photographs of the morphological and genital characters of the new records are presented.
