The aim of this study was to determine Coleoptera succession in pig carcasses in Eskişehir Province, Turkey, and to evaluate differences in successional patterns between rural and urban habitats. A total of 24 pig carcasses were placed in rural and urban areas in Eskişehir Province for one-year period between June 2012 and May 2013. A total of 80 species belonging to the families Staphylinidae, Histeridae, Dermestidae, Silphidae and Cleridae (Coleoptera) were collected either directly from carcasses or sifted for the specimens hiding in the soil. The months and duration of all species on the different stages of carcass decomposition were recorded. In addition, new records were added to the Coleoptera fauna of carcass for Turkey. The study revealed that, both species number and activity periods were different even in areas very close to each other. It is suggested that this type of long-term succession study should be performed across all provinces of Turkey. Acquired data could potentially be used for estimating the minimum post-mortem interval in forensic cases in Turkey.

and Yozgat provinces (Figure 1). The Central Anatolian Region is the second largest region of Turkey after the Eastern Anatolian Region and, excluding the Southeastern Anatolian Region, it is adjacent to the remaining six regions of Turkey. The region is divided into four sections as Konya, Upper Sakarya, and Middle and Upper Kızılırmak. It has a plains profile in terms of landforms. While vast plains are found in the middle part, mountains extends around the borders. In the south, there are volcanic mountains extending in parallel with the Middle Taurus mountain range: Erciyes, Melendiz, Hasandağı, Karacadağ, and Karadağ from north to south. The most important streams and rivers of the Central Anatolian Region are the Kızılırmak, Sakarya, Porsuk, and Delice. Lake Tuz is the largest lake of the region and Akşehir, Eber, Ilgın (Çavuşçu), Tuzla, Seyfe, Mogan, and Sultansazlığı are other important lakes.

In this study, a new Aleocharinae (Coleoptera: Staphylinidae) species from Turkey, Gyrophaena cagatay sp. n. (Aksaray), is described and illustrated. In addition, new records are presented for seven species: Atheta hygrotopora (Kraatz, 1856), Atheta incognita (Sharp, 1869), Atheta ripicola Hanssen, 1932, Brachyusa concolor Erichson, 1839, Ischnopoda leucopus (Marsham, 1802), Ischnopoda subaenea Eppelsheim, 1890, and Liogluta granigera Kiesenwetter, 1850. Photographs of the habitus of male and female specimens are presented. The 8th tergite and aedeagus of the male and the spermatheca of the female are also illustrated for the new species. Differential diagnosis guidelines are given for comparisons with Gyrophaena rousi Dvořak, 1966.
