Özet
Bu çalışmada, Türkiye’den toplanan Cryptocephalus türlerinin erkek ve dişi genital organlarının morfolojileri sunulmaktadır. Cryptocephalus cinsi Türkiye’de 73 tür ile temsil edilmekte olup, bunların 36’sı (yaklaşık %49,3’ü) koleksiyonumuzda bulunmaktadır. Bugüne kadar Türkiye’de Cryptocephalinae alt familyasına ait türlerin erkek genital organı (aedeagus) ve dişi genital organının (spermateka) morfolojilerinin birlikte incelendiği herhangi bir çalışma yapılmamıştır.
Bu nedenle, bu çalışma, Cryptocephalus Geoffroy cinsinin nominotipik alt cinsi olan Cryptocephalus içerisinde yer alan seçilmiş türlerin erkek ve dişi genital morfolojilerini değerlendirmeyi amaçlamaktadır. Gözlemlenen morfolojik farklılıklar, nominotipik alt cinsin polifiletik olabileceğine işaret etmektedir. Bu bulgular, bazı türlerin mevcut diğer alt cinslere aktarılmasının veya yeni bir alt cins oluşturulmasının gerekli olup olmadığını belirlemek için daha ileri taksonomik çalışmalara ihtiyaç duyulduğunu göstermektedir.
Dolayısıyla, bu çalışmanın amacı, stereomikroskop altında görülemeyen ultrastrüktürel özellikleri ortaya çıkarmak ve nominotipik Cryptocephalus alt cinsinin alt gruplara ayrılmasında kullanılabilecek erkek ve dişi genital organlarına ait ayırt edici karakterleri belirlemek amacıyla erkek ve dişi genital yapılarını taramalı elektron mikroskobu (SEM) kullanarak incelemektir.
We present the morphologies of male and female genitalia of Cryptocephalus speciescollected from Turkey. The genus Cryptocephalus is represented by 73 species in Turkey,36 of which (approximately 49.3%) are in our collection. To date, there has been no studyin Turkey in which the morphology of the male genitalia (aedeagus) and female genitalia(spermatheca) of the subfamily Cryptocephalinae have been studied together.Therefore, this study aims to evaluate the male and female genital morphology ofselected species of the genus Cryptocephalus Geoffroy within the nominate subgenusCryptocephalus. The observed morphological differences may indicate that the nominatesubgenus is polyphyletic. These findings suggest that further taxonomic studies areneeded to determine whether some species should be assigned to other existingsubgenera or whether the establishment of a new subgenus is warranted. Therefore,the aim of this study is to examine the male and female genitalia by SEM to elucidate theultrastructural properties that cannot be seen under a stereo microscope and to distin-guish the male and female genital organs that will be used in the subdivision of thenominate subgenus Cryptocephalus
