Abstract

It is accepted male genitalia are not diagnostic, but spermathecae are partly diagnostic within the genus Cassida Linnaeus, 1758 (Coleoptera: Chrysomelidae: Cassidinae). However, studies on genitalia have been based only on stereomicroscopic examination. The ultrastructure of genitalia has mostly not been studied. The aim of this study was to determine whether this ultrastructures could be diagnostic. Aedeagi and spermathecae of 63 specimens of Cassida viridis Linnaeus, 1758 were collected from Çankırı, Hatay, Kayseri, Osmaniye and Zonguldak Provinces in Turkey in 2003, 2007 and 2015, and examined for the first time. Thus, new diagnostic characters were obtained and it revealed that it was diagnostic to either species or subgenus. Photos of aedeagus and spermatheca taken with both SEM and stereomicroscope are given.

Türkiye'den Cassida viridis Linnaeus, 1758 (Coleoptera: Chrysomelidae: Cassidinae)'in aedeagus ve spermatekaları üzerine bir SEM çalışması

Abstract

Cassida Linnaeus, 1758 (Coleoptera: Chrysomelidae: Cassidinae) cinsi içerisinde genel olarak erkek genitalinin ayırt edici olmadığı, ancak spermatekanın kısmen ayırt edici olduğu kabul edilmektedir. Bununla birlikte şimdiye kadar yapılan genital çalışmalarının sadece stereo mikroskoba dayalı olduğu görülmektedir. Genital yapılarının ince yapısı çoğunlukla çalışılmamıştır. Bu çalışmanın amacı, bu altyapının tanısal olup olmayacağını belirlenmesiydi. Bu çalışmada Çankırı, Hatay, Kayseri, Osmaniye ve Zonguldak (Türkiye) illerinden 2003, 2007 ve 2015 yıllarında toplanan toplam 63 Cassida viridis Linnaeus, 1758 örneğine ait aedeagus ve spermateka yapıları ilk defa olarak incelenmiştir. Bu sayede yeni ayırt edici karakterler elde edilmiş ve diğer bir alt cinsteki daha önce çalışmış türlerden ayırt edici olduğu ortaya konulmuştur. Aedeagus ve spermatekanın hem SEM hem de stereo mikroskop fotoğrafları da çalışma içerisinde sunulmuştur.
