Abstract

The
main objectives of the study were to determine the adequacy and reliability of
characters used for identification of Ormyrus (Ormyridae: Hymenoptera)
species, and the relationships between species within the genus by numerical
taxonomic analysis. The specimens studied were collected in Sivas Province in
2010. Individual females of five species in to Ormyrus were examined.
One hundred morphological characters were measured for 249 specimens. Three
different numeric taxonomic analyses were performed, principal component,
principal coordinate, and cluster analyses, using computer package software
PAST. Principal components and coordinate analyses revealed the with characters
of sufficient value to reliability distinguish five species of Ormyrus.
Examination of the relationship between the five species by clustering analysis
showed that the species belonged to two different main groups. The robustness
of the currently available identification keys and new characters that could be
used for of species identification was also determined.

Sivas İli Ormyrus Westwood, 1832 (Ormyridae: Hymenoptera) türleri üzerinde nümerik taksonomik çalışmalar

Abstract

Çalışmanın asıl amacı nümerik taksonomik
analiz ile Ormyrus cinsine ait türlerin teşhisinde kullanılan karakterlerin
kalite ve güvenilirliğini ve türler arasındaki akrabalık ilişkilerini
belirlemektir. Çalışılan örnekler 2010 yılında, Sivas ilinden toplanmıştır. Ormyrus
Westwood (Ormyridae: Hymenoptera) cinsine ait 5 türün dişi bireyleri
incelenmiştir. 249 örnek için 100 morfolojik karakter ölçülmüştür. PAST
bilgisayar paket programı kullanılarak Temel Bileşenler Analizi, Temel
Koordinat Analizi ve Kümeleme Analizi olmak üzere üç farklı nümerik taksonomik
analiz yapılmıştır. Yapılan Temel Bileşen ve Koordinat analizleri sonucunda,
belirlenen karakterlerin, Orymrus cinsine ait 5 türü tamamen birbirinden
ayıracak yeterlilikte ve güvenilirlikte olduğu gösterilmiştir. Yapılan kümeleme
analizi ile Orymrus cinsine ait 5 türün birbirleriyle olan akrabalık
dereceleri belirlenerek, bu türlerin iki ayrı ana grup oluşturduğu
gösterilmiştir. Mevcut teşhis anahtarlarının güvenilirliği ve teşhislerde
kullanılabilecek yeni karakterler belirlenmiştir.
