Abstract

The harvestmen species Pyza taurica
Gruber, 1979 (Opilionida, Nemastomatidae) is endemic to Anatolia. In this study,
external morphology of P. taurica was investigated in detail by using scanning electron
microscope (SEM). Cuticular structures and sense organs on the segments of
legs, pedipalps, chelicerae, and the dorsal integument of male specimens of P.
taurica are investigated and depicted, in particular, characters of
taxonomic and systematic importance. Such studies are needed especially for
understanding the functional anatomy and morphology of opilionids.

Pyza taurica'nın Gruber, 1979 Dış Morfolojisi (Arachnida: Opiliones)

Abstract

Pyza taurica Gruber,
1979 (Opilionida, Nemastomatidae) otbiçen türü Anadolu’ya özgüdür. Bu çalışmada, P. taurica'nın
dış morfolojisi ayrıntılı olarak taramalı elektron mikroskopu (SEM)
kullanılarak araştırılmıştır. Özellikle taksonomik ve sistematik önem taşıyan
karakterde, bacaklar, pedipalp, chelicerae ve P. taurica erkek örneklerinin
dorsal üzerindeki kesici yapılar ve duyu organları incelenmekte ve tasvir
edilmektedir. Bu gibi çalışmalar, özellikle otbiçenlerin fonksiyonel
anatomisini ve morfolojisini anlamak için gereklidir.

Keywords
