Abstract

Two new species of Trichoptera from Turkey are described and illustrated:Chaetopteryx akgolensissp.n. andChaetopteryx sinopicasp.n. (Limnepphilidae). Both belong to the tribe Chaetopterygini in the Limnephilinae.C. akgolensissp.n. is close toC. bektasensisSipahiler, 2008, whereasC. sinopicasp.n. is closely related toC. nalanaeSipahiler, 1996. The previously unknown female ofChaetopteryx bektasensisSipahiler, 2008 is described and figured.

Highlights

The genus Chaetopteryx Stephens was previously thought to be represented in Turkey by four species
Two new species of this genus are described: C. akgolensis sp.n., which is closely related to C. bektasensis and C. abchazica, and C. sinopica sp.n., which is close to C. nalanae
The following differences exist in the male genitalia: in C. nalanae, in dorsal view, the spinulose zone of tergite VIII is nearly trapezoidal, the apical and lateral edges are straight, the preanal appendages are broadly rounded and without petioles on the ventral parts, the intermediate appendages are long and narrow, the phallic apparatus very large on the apical portion, of which the sides are rounded, and the parameres are broad on the distal portion

Summary

Introduction

The genus Chaetopteryx Stephens was previously thought to be represented in Turkey by four species. C. bosniaca Marinkovic, 1955 (found in the Carpathians, the Balkans, and Turkey) and C. abchazica (Martynov, 1916) (found in the Caucasus, Iran, and northeastern Turkey), are widely distributed species; the others, C. bektasensis Sipahiler, 2008 and C. nalanae Sipahiler, 1996 have restricted distributions, being found in northeastern and northwestern Turkey, respectively [1–3]. Two new species of this genus are described: C. akgolensis sp.n., which is closely related to C. bektasensis and C. abchazica, and C. sinopica sp.n., which is close to C. nalanae.
