Due to some biological features, species belonging to genus Dorcadion Dalman, 1817 (Coleoptera: Cerambycidae) can be easily divided into isolated populations. This can be considered as an important factor of speciation process and allows the observation of various effects of biological evolution of taxa. These effects can be measured on morphological characters with some different approaches such as geometric morphometrics. This study aims to determine pronotum and elytra shape differences of the samples of three isolated localities of Turkey (Akyurt, Bala, and Beynam) detected in Ankara, and to contribute to taxonomic and evolutionary knowledge of Dorcadion micans Thomson (1867) by evaluating the analysis of outcomes. As a result, significant differences between populations were detected both in pronotum and elytra. Besides, common variations were observed in some morphological characters of the Bala and Beynam populations, unlike Akyurt population. Accordingly, the distinguishing ...

The karyotypes of four species of Cleridae (Coleoptera): Trichodes favarius (Illiger, 1802), Trichodes quadriguttatus Adams, 1817, Trichodes reichei (Mulsant et Rey, 1863), and Tilloidea transversalis (Charpentier, 1825) were reported for... more
The karyotypes of four species of Cleridae (Coleoptera): Trichodes favarius (Illiger, 1802), Trichodes quadriguttatus Adams, 1817, Trichodes reichei (Mulsant et Rey, 1863), and Tilloidea transversalis (Charpentier, 1825) were reported for the first time with this study. The chromosome numbers of these four species were determined as 2n = 18, sex chromosome system Xyp, and all chromosomes were metacentric (the except y chromosome). Together with this study, the chromosome data of only 17 species are available in this family. It is remarkable that all of them display the same chromosome number and similar karyotypes. This may make the effect of karyotypical features important in interpreting the evolutionary process of Cleridae.

Dorcadion Dalman, 1817 (Coleoptera: Cerambycidae) cinsi turleri toprak yuzeyinde yasayan ve ucma kabiliyetleri olmayan turlerdir. Ancak bu turlerin populasyonlari birbirlerinden kolayca izole olabilirler. Bu tarz biyolojik ozellikler turlesme surecini hizlandiran onemli faktorler olarak dusunulebilir. Izole populasyon en etkileri orneklerin morfolojik karakterleri uzerinden olculebilir. Taksonomistlerin cinsin tanimlamasinda kullandigi morfolojik karakterler genel olarak ozneldir. Bu durum bazi sistematik problemlere neden olmaktadir. Turkiye’ye endemik olan Dorcadion anatolicum Pic, 1900 (Coleoptera: Cerambycidae) turunun bazi populasyonlarinin alttur statusu tartismalidir. Bu calismanin amaci, iki izole lokaliteden alinan orneklerin pronotum sekil farkliliklarini geometrik morfometri analizleri ile belirlemek ve D. anatolicum 'un taksonomik ve evrimsel durumuna katkida bulunmaktir. Calismada kullanilan ornekler Turkiye’nin iki farkli populasyonundan (Kahramanmaras ve Konya) 2018 yili mart ve nisan aylarinda toplanmistir. Morfometrik analiz sonuclari orneklerin pronotum sekil degisikliklerinin, populasyonlarin morfolojik anlamda ayrimina izin verdigini ortaya koymustur.
