A New Type Covering Setae Morphology in Crab Spiders (Araneae)

Öz

The present study aims to determine the covering setae in two crab spiders using scanning electron microscopy (SEM). The setae on the prosoma of Runcinia grammica (C. L. Koch, 1837) and Thomisus onustus Walckenaer, 1805 were examined. This study reveals a new type of covering setae in the members of Thomisidae family.

Yengeç Örümceklerinde (Araneae) Yeni Bir Tip Örtü Setası Morfolojisi

Öz

Mevcut çalışmada taramalı elektron mikroskobu kullanılarak iki yengeç örümceği türünde örtü setalarının morfolojisinin belirlenmesi amaçlanmıştır. Runcinia grammica (C. L. Koch, 1837) ve Thomisus onustus Walckenaer, 1805 türlerinin prosomaları üzerindeki setalar bu amaçla incelenmiştir. Thomisidae familyası üyelerinde ilk kez görülen bir örtü setası tipine rastlanılmıştır.
