The geographic structure of Türkiye is well-suited for determining species diversity and interspecific variation as Türkiye has many regions with different altitudes and ecological characteristics. A large number of specimens belonging to the Helophoridae family belonging to the order Coleoptera were collected from different regions of Turkey between 2007-2021, examined and kept as museum material. Among the museum materials evaluated in terms of variation, Helophorus (Helophorus) aquaticus (L., 1758) species were seen to be both more common and more diverse in each region. In this study, male specimens varying in color, size, pronotum, tarsi, and genital structure were selected among the samples collected from different regions and geographic locations within the same locality. A total of 17 different morphological variations were identified and listed by examining the pronotum, elytra, tarsi, and aedeagophore structures. The relationships of these variations with altitude have been evaluated. As a result of this study, it has been determined that variations of the same species can coexist in the same locality, as well as similar variations in localities in different geographical regions. In addition, it was determined that the size of the insects increased as the altitude increased.

Türkiye'nin coğrafi yapısı tür çeşitliliğini ve türler arası varyasyonu belirlemeye oldukça elverişlidir ve Türkiye'nin farklı rakımlara ve farklı ekolojik özelliklere sahip birçok bölgesi vardır. Coleoptera takımı Helophoridae familyasına ait çok sayıda örnek 2007-2021 yılları arasında Türkiye'nin farklı yörelerinden toplanmış, incelenmiş ve müze materyali olarak saklanmıştır. Varyasyon açısından değerlendirilen müze materyalleri arasında, Helophorus (Helophorus) aquaticus (L., 1758) türlerinin her bölgede hem daha yaygın hem de daha çeşitli olduğu görülmüştür. Bu çalışmada, farklı bölgelerden ve farklı coğrafi konumlardan toplanan ve aynı lokasyonu paylaşan erkek örnekler arasından farklı renk, boyut, pronotum, tarsi ve genital yapılara sahip bireyler seçilmiştir. Pronotum, elytra, tarsi ve aedeagophore yapıları incelenerek toplam 17 farklı morfolojik varyasyon tanımlanmış ve listelenmiştir. Bu varyasyonların rakım ile ilişkileri değerlendirilmiştir. Bu çalışma sonucunda, aynı türün varyasyonlarının aynı lokalitede bir arada bulunabileceği gibi, farklı coğrafi bölgelerdeki lokalitelerde de benzer varyasyonların olabileceği tespit edilmiştir. Ayrıca rakım arttıkça böceklerin boyutlarının da arttığı tespit edilmiştir.
