The Harvestmen Fauna (Opiliones, Arachnida) of the City of Sofia (Bulgaria) and its Adjacent Regions

This is the dataset for: Plamen G. Mitov, Ivailo L. Stoyanov (2004) The Harvestmen Fauna (Opiliones, Arachnida) of the City of Sofia (Bulgaria) and its Adjacent Regions. In: L. Penev, J. Niemelä, D. J. Kotze & N. Chipev (Eds.) Ecology of the City of Sofia. Species and Communities in an Urban Environment, Pensoft, 319-354. Abstract: This is the first paper dealing with the opilionid fauna of urban park-areas (located in the city of Sofia) in Bulgaria. In addition, the harvestmen fauna of the regions surrounding the city of Sofia is summarized. The faunistic list presents data on the 32 species hitherto found in the covered area. Two of them (Trogulus closanicus and Rilaena serbica) are new to the Bulgarian fauna, and a further one, referred herein as Rilaena cf. serbica, is currently of unclear taxonomical status. A detailed analysis of the opilionid assemblages (both local and regional) under study is provided, and hypotheses concerning the genesis and development of the urban fauna are presented. This dataset includes both the raw (presence-absence) community data as well as the summarized data from Table 1 and Table 2 in the paper.
