NEW TRAMP ANT SPECIES FOR TURKEY : Tetramorium lanuginosum Mayr ( HYMENOPTERA : FORMICIDAE )

Human activities such as tourism, developed transportation and increased trade lead to the introduction of faunal elements into non-native habitats and consequently affect native fauna. These introduced species are called as non-native, exotic, invasive or tramp species. Here we record the well-known tramp species Tetramorium lanuginosum Mayr, for the first time from Turkey (Antalya-Alanya), and present first locality records for Paratrechina longicornis (Latreille) from AntalyaAlanya and Adana. Thus, the number of tramp ant species of Turkey is increased to 19.

Turkey is an important destination for tourism (Tursab 2016), with more than 35 million tourists who visited the country each year in the last decade.The geographic position of Turkey as a peninsula and the increased internal and external trade activities by shipping resulted in the introduction of non-native ant species to the country.For instance, Anoplolepis gracilipes (F.Smith), Camponotus compressus (Fabricius), C. maculatus (Fabricius), Hypoponera punctatissima (Roger), Linepithema humile (Mayr), Solenopsis geminata (Fabricius), Paratrechina longicornis (Latreille), and Tetramorium bicarinatum (Nylander) have recently been recorded from Turkey as tramp species (Borowiec 2014), but without their distribution localities.According to the records of Borowiec (2014) and AntWeb (2017) the current number of tramp species known from Turkey is 32.
Here we present a new tramp ant species T. lanuginosum Mayr from Antalya-Turkey and give the first locality based records of P. longicornis (Latreille) from Antalya and Adana.
Antalya-Alanya and Adana is characterized by a Mediterranean type climate with hot and dry summers and mild and wet winters.The average annual temperature and precipitation values are 18.7°C and 1087mm for Antalya-Alanya and 19.3°C and 679mm for Adana, respectively.Moreover, the average temperature of winter season of these two provinces never fall below 10°C (Climate-data.org).

Results
Tetramorium lanuginosum Mayr (Fig. 1) Diagnosis: Tetramorium lanuginosum with T. bicarinatum are among the few Turkish ants with antennal scrobe.Tetramorium lanuginosum can be readily discriminated from T. bicarinatum and from other Turkish Tetramorium species by the long and profuse bifid pilosity.

Paratrechina longicornis (Latreille) (Fig. 2)
Diagnosis: Paratrechina longicornis is differentiated from all other species of the genus by 5 toothed mandibles, the stiff and blunt hairs and the bare antennal scape.

Discussion
The tramp ant species have been known since more than one century.Forel (1911)    New Tramp Ant Species for Turkey: Tetramorium lanuginosum Mayr (Hymenoptera: Formicidae) Four of these serious pest ant species (A.gracilipes, L. humile, S. geminata and P. longicornis) were reported from Turkey by Borowiec (2014) without exact locality records.Monomorium pharonis and P. megacephala were recorded by different researchers from different localities in Turkey.The other problematic species, T. destructor, is a native ant species for Turkish ant fauna and only one of them (Tapinoma melanocephalum) has not been recorded so far from Turkey.
The records available from Borowiec (2014) and AntWeb (2017) point out presence of at least 32 tramp ant species from Turkey (Table 1).However, 14 ant species (Table 1; written as red) from this list are native to Turkey because their native distribution range comprise Turkey.As a result, the exact and real tramp ant species number of Turkey needs to be revised as 18 (Table 1; written as black).
Tetramorium lanuginosum is widely distributed across tropical and subtropical regions with several records in countries in Western Palearctic (Egypt, England, Israel, Lebanon, Libya, Malta, Netherlands, Spain, Tunisia and Saudi Arabia).We recorded T. lanuginosum from two different urban habitats, pavements of historical bazaar and a coastal road in Alanya (Figure 3A).These findings let us to conclude without doubt that T. lanuginosum is settle to Alanya and became a putative permanent tramp species.
Paratrechina longicornis has been recorded in the Western Palearctic Region from Algeria, Azores, Balearic Islands, Belgium, Canary Islands, Czech Republic, Denmark, Egypt, England, Estonia, France, Netherlands, Germany, Gibraltar, Greece, Iran, Iraq, Israel, Italy, Lebanon, Libya, Malta, Morocco, Saudi Arabia, Spain, Sweden, Switzerland, Syria and United Arab Emirates.We recorded P. longicornis in a semi-rural area of Alanya castle (Figure 3B).The workers were collected from Pinus brutia Tenore trunk where they were most probably feeding with aphid honeydew.The Adana record of the species was also from semi-rural area but no information on its biology is available.
Boer & Vierbergen (2008) divided the tramp ant species into 4 groups as intercepted tramps, temporary tramps, local tramps and permanent tramps according to their existence in a country.According to Boer and Vierbergen's classification, local tramps are non-native ant species moved away from the entry medium and dispersed to settle a temporary population.Permanent tramps are also non-native ant species who settled permanent populations and spread different locations.We, therefore, can categorize T. lanuginosum as a local tramp and P. longicornis as a permanent tramp species.Many tropical and subtropical ant species will become tramp ant species in the future due to global warming (Boer & Vierbergen 2008).In conclusion, the current and exact number of tramp ant species in Turkey, after the exclusion of 14 species, all which were regarded as to have a native distribution in Turkey, from the list one can deduce considering the data in Borowiec (2014) and AntWeb (2017) (see Table 1), is increased to 19 by the present record of T. lanuginosum.We are expecting that this number will increase in the future with more collecting efforts in urban and semi-rural areas especially in southern parts of Turkey.
