Paratanytarsus laetipe s (Zetterstedt, 1850)

Material: Demirköy - Saka Lake , 41°48ʹ0ʺN, 27°59ʹ40ʺE, 07.07.2013, 1♂ .

Distribution in the world: Austria, Belgium, France and Corsica, Finland, Germany, Hungary, Italy, Netherlands, Poland, Romania, Slovakia, Sweden, Switzerland ( Serra-Tosio and Laville, 1991; Tatole, 2000; Arnold and György, 2004; Ekrem et al., 2007; Gilka and Dominiak, 2007; Paasivirta, 2014).

Habitat: It was collected among greenery near the lake.

Remarks: This species was identified from the adult form and its larvae were not encountered. The wing membrane of the species bears macrotrichia and always squama is bare. Combs of hind tibia with 2 spurs. The distinguishing features of the species are inner margin of inferior vorsella expanded in the distal half and flattened setae of median vorsella club-shaped ( Figure 2 ).

In the present study, Cladotanytarsus (Cladotanytarsus) mancus was the most prevalent species, in terms of both larval and adult samples, as expected, since it is a multivoltine species. When the identified species were evaluated on the basis of their subfamilies, most of the species were found to belong to Chironominae (61%), followed by Orthocladiinae (23.4%), Tanypodinae (14.1%), and Prodiamesinae (1.5%).

Chironomus plumosus , Chironomus viridicollis , Chironomus anthracinus , and Chironomus riparius are

AYDIN and GÜHER / Turk J Zool known as bioindicator species ( Epler, 2001; Armitage et al., 1995) and they were commonly sampled during our study period. This finding about the bioindicator species led us to think that a pollution load occurred in the research area.

In conclusion, larval and adult chironomids were evaluated together taxonomically. We conclude that, in order to obtain reliable data on taxonomical positions of Chironomidae , particularly for some members of the family, a simultaneous identification of both larval and adult specimens will provide valuable data for a clear
