The Alydidae (Heteroptera: Coreoidea) of Turkey: A Key to the Genera, New Records and a Species Checklist

Abstract

In this study, 110 adult Alydidae (Coreoidea) specimens belonging to 4 genera and 7 species
were collected from 25 different localities in Anatolia in 2008-2009. These new records increased the number
of Turkish Alydidae genera from 2 to 4 and species from 5 to 7.
A key to the Alydidae genera of Turkey is provided. Megalotomus ornaticeps (Stål, 1858) and Namausus sordidatus (Stål, 1858) are recorded for the first time from Turkey, redescribed and their genitalia are illustrated

ABSTRACT: In this study, 110 adult Alydidae (Coreoidea) specimens belonging to 4 genera and 7 species
were collected from 25 different localities in Anatolia in 2008-2009. These new records increased the num-
ber of Turkish Alydidae genera from 2 to 4 and species from 5 to 7. A key to the Alydidae genera of Turkey
is provided. Megalotomus ornaticeps (Stål, 1858) and Namausus sordidatus (Stål, 1858) are recorded for
the first time from Turkey, redescribed and their genitalia are illustrated.
KEY WORDS: Turkey, Alydidae, Megalotomus, Nemausus, new records
INTRODUCTION
The Family Alydidae is in the superfamily Coreoidea. Worldwide, there are ap -
prox i mately 200 known species belonging to 50 genera. In the Palaearctic Region; 69
species belonging to 26 genera have been identified (Dolling, 2006). In Turkey, 5
species from 2 genera have been previously recorded (Pehlivan, 1981; Önder et al.,
2006; Dolling, 2006).
There have been many studies of the Alydidae of Turkey conducted by both native
and foreign researchers: Amasya (Fieber, 1864); Hatay (Horváth, 1901); Istan bul
(Fah ringer, 1922); Kars (Kiritshenko, 1918, 1924); Adana, Ankara, Edirne (Hober -
landt 1955; Seidenstücker 1957); Mersin, Istanbul (Linnavuori, 1965); Aydın (Wag -
ner, 1966; Pehlivan 1981); in all parts of Turkey, Ankara, Elazıg˘, Kayseri (Kıyak,
1990a, b, 1993) and Kelkit Valley (Dursun, 2009). Col lec tively, these investigators
reported Alydus calcaratus (Linnaeus, 1758), Camptopus bifasciatus Fieber, 1864,
Camptopus illustris Horváth, 1899, Camp topus lateralis (Germar, 1817) and Camp -
topus tragacanthae (Kolenati, 1845). Alydidae are generally phytophages of Poaceae
and Fabaceae but in North America Alydus calcaratus has been reported to feed on
some animals (Pehlivan, 1981).
Our research area covered parts of both the Iran-Turan flora region and Medi ter -
ranean region. The principal aim was to collect specimens in the Eastern Ana tolia
Region near the borders of Armenia, Georgia and Syria, and especially Iran, in order
to increase knowledge of the Turkish Alydidae fauna.
MATERIALS, METHODS AND RESULTS
Our research material consisted of 110 adult Alydidae specimens collected from 25
localities with different vegetation and habitat properties in the pro vinc es of Adana,
Ag˘rı, Ardahan, Erzincan, Erzurum, Ig˘dır, Kars, Mersin and Van in 2008-2009, espe-
cially in areas near the Turkish borders with Iran, Na hcivan, Armenia, Georgia and

Syria. Specimens were collected from plants with the help of a net and killed in a bot-
tle with ethyl acetate. Specimens were preserved in a cardboard box in a cool envi-
ronment before laboratory processing to prevent mildew. Coordinates of the collec-
tion locations were logged with a hand-held Global Positioning System (GPS). In the
laboratory, samples were softened in 5% acetic acid before the extraction and pinning
of male genitalia.

Measurements of body parts were done with a Leica MZ 125 stereomicroscope,
photographs taken with a Leica digital camera and drawings completed. Species were
identified using Stichel (1960), Kerzhner and Jaczewsk (1964), Pehlivan (1981) and
Kıyak (1990a, 1990b). Several of our specimens were compared with specimens held
in the Museum für Naturkunde, Berlin, Germany. Study site data are summarized in
Table I. Specimens are preserved at the Faculty of Arts and Science at Amasya Uni -
ver sity, Amasya, Turkey.
To date, a complete list of the Alydidae of Turkey has not been published. The main
reference for the current study was the Catalogue of the Heteroptera of the Palae -
arctic Region (Dolling, 2006). A total of 2 genera and 5 species were recorded for
Turkey before this study (Pehlivan, 1981; Önder et al., 2006; Dolling, 2006). Mea -
surements are in mm and the diagrams have scales.

DISCUSSION
There are 69 species belonging to 26 genera from the family Alydidae known in the
Palearctic Region. Five species belonging to 2 genera were known from Turkey
(Pehlivan, 1981; Önder et al., 2006; Dolling, 2006; Dursun, 2009). In previous stud-
ies in Turkey, no species belonging to the genus Megalotomus Fie ber, 1860 and
Namausus Stål, 1866 had been reported. We report the genus Megalotomus and the
species Megalotomus ornaticeps (Stål, 1858), as well as the genus Namausus and the
species Namausus sordidatus (Stål, 1858), as new records for Turkey. Megalotomus
ornaticeps and Namausus sordidatus from specimens collected this study, museum
specimens, and from descriptions in the literature.
The five species previously reported from Turkey were Camptopus bifasciatus first
recorded from Turkey by Fieber (1864); Camptopus lateralis; Camptopus tragacan-
thae first recorded from Turkey by Horváth (1883); Alydus calcaratus, first recorded

from Turkey by Horváth (1905); and Camptopus illustris first recorded from Turkey
by Kiritshenko (1918) and again by Pehlivan (1981). During this study, new locali-
ties were recorded for: Camptopus tragacanthae (Igdir); Camptopus lateralis (Ag˘rı,
Erzincan, Erzurum, Ig˘dır, Kars and Van); and Alydus calcaratus (Erzincan). Among
the seven species now known for Turkey, Camptopus lateralis had the widest distri-
bution.
Seven species of Megalotomus are known from the Palaearctic Region. They are
Mega lotomus acutulus Liu&Liu, 1998; Megalotomus castaneus Reuter, 1888; Mega -
lotomus costalis Stål, 1873; Megalotomus junceus (Scopoli, 1763); Megalotomus ob -
tusus Gauri, 1972; Megalotomus ornaticeps and Megalotomus zaitzevi Kerzhner,
1972. One species of the genus Namausus (Namausus sordidatus) is known from the
Palaearctic Region.
Species of Megalotomus are most common in Asia. Their distribution in the Pale -
arctic region is mostly in the Euro-Siberian and Irano-Turanian Floristic Regions.
Megalotomus ornaticeps has been recorded from Azerbaijan, Armenia and Georgia,
which all border the study area, and Namausus sordidatus is known from Iran, which
also borders the study area (Fig. 5) (Dolling, 2006). In the literature, there are no
records of host plants for Megalotomus ornaticeps and Namausus sordidatus. In this
study, it was determined that a host plant for Megalotomus ornaticeps is Prosopis
farcta (Fabaceae) and for Namausus sordidatus a host plant is Olea oleaster (Olea -
ceae).
