Faunistic study of the aquatic beetles (Coleoptera) of Trabzon province (Turkey)

Abstract

In this study, we established the presence of 26 aquatic beetle species belonging to 16 genera and 5 families from the Trabzon province in the Black Sea region of Turkey. Specimens were collected between 2005 and 2006. Distributions of species within Turkey are presented as a catalogue of provincial records. Ten species are here recorded for the first time from the Black Sea region of Turkey. Several species known previously from only a few localities in Turkey have been shown to have much wider distributions in the country. In addition, the habitats and the phenologies of these species found in the area were given.

ABSTRACT: In this study, we established the presence of 26 aquatic beetle species
belonging to 16 genera and 5 families from the Trabzon province in the Black Sea region of
Turkey. Specimens were collected between 2005 and 2006. Distributions of species within
Turkey are presented as a catalogue of provincial records. Ten species are here recorded for
the first time from the Black Sea region of Turkey. Several species known previously from
only a few localities in Turkey have been shown to have much wider distributions in the
country. In addition, the habitats and the phenologies of these species found in the area
were given.
KEY WORDS: Coleoptera, Gyrinidae, Noteridae, Dytiscidae, Hydrophilidae, Helophoridae,
fauna, Trabzon, Turkey.
Aquatic beetle fauna of Trabzon province is only partly known. Twenty
four species of aquatic beetles have been recorded from the studied
region in the following published works: Balfour–Browne (1963), Gentili
& Chiesa (1975), Guéorguiev (1968; 1981), Angus (1988; 1992), Brancucci
(1988), Gentili (1981; 2000) and Fery & Petrov (2005).
The aim of this study was to make a contribution to Turkish aquatic
beetles fauna.
MATERIALS AND METHOD
This study is based on 495 specimens of aquatic beetles and all the
specimens were collected by the first author from Trabzon province (Map
1) between June – September in 2005 and 2006. Specimens were
collected from a spring water area, with a sieve, ladle and net having a 1
mm mesh size. The beetles were killed with 70% alcohol and in the
laboratory were cleaned of muddy remnant on their surfaces with a small
paintbrush. Aedeagophore was dissected under the stereo-microscope
and on to add 10% KOH solution for about 1–2 hours. Materials have
been deposited in the Gazi University Zoological Museum (=ZMGU),
Ankara, Turkey.
A list of localities is given in Table 1. The ‘List of species” gives the
sampling locations for each species. The dates of sampling and total
number of individuals are also noted. Species new for Trabzon are
marked with an asterisk, species new for Black Sea Region of Turkey with
two asterisks.
