New data on distribution, biology, and ecology of some little-known cerambycid species, collected in the western part of Tajikistan, are presented. Arhopalus rusticus (Linnaeus, 1758) is recorded in Tajikistan for the first time. New localities of species considered pests or invasive species such as Aeolesthes sarta (Solsky, 1871) and Xylotrechus stebbingi Gahan, 1906 are also given. The list of the taxa collected by the first author during many years of field research in Tajikistan as well as photographs of poorly known species from his collection, including some endemics, are additionally provided. Furthermore, high quality photographs of some extremely rare species that were collected during our expedition, i.e., Turkaromia gromenkoi Danilevsky, 2000 and Ropalopus nadari Pic, 1894, with images of their habitats or feeding grounds are also presented for the first time.
Central Asia, endemic species, faunistics, invasive species, new records, zoogeography
The longhorn beetle family (Cerambycidae) is one of the most species-rich groups of beetles (Coleoptera) with approximately 35,000 described species (
Tajikistan is located almost entirely within the Pamir-Alay Mountain range although forests only cover 2.6% of the area of the country. That places this country on one of the last positions regarding woodiness among the republics of the former Soviet Union. Some relict species such as Juglans regia, Acer turkestanica, and A. reggeli used to occur in Tajikistan in the past but they are totally extinct as a result of intensive cutting and burning of forests (
The state of the knowledge of the longhorn fauna of Tajikistan (particularly, of the region of the Pamir Mountains) as well as information about the biology and ecology of some species that are distributed in the region is very poor. Therefore, the present study aims to supplement the knowledge in this field.
Tajikistan is a relatively small intra-continental country situated at the boundary of the subtropical and temperate climatic zones. It is located in the mountain desert zone of the Eurasian continent in the southern part of Central Asia, where ecosystems such as deserts, steppes, savannoides, conifer forests, mixed mountain forests, high-mountain deserts, and glaciers are widely represented. The changeable mountain climatic conditions and hard historical natural processes have promoted the formation of a unique biological diversity in Tajikistan, which counts many relict and endemic species (
The entomological expedition, which consisted of four scientists from the Department of Zoology, University of Silesia (Poland), took place at the turn of June and July 2014. During the research, several sampling trips were carried out to various locations in the western part of Tajikistan (Map
Tajikistan has a wide variety of habitats that range from gravel deserts in the south through green mountain valleys in the central part of the country to the high mountains with glaciers in the north and east. The area studied includes several different nature ecosystems such as alpine meadows, mesophilic shrubs, various shrub steppes, broad-leaf forests, light forests, and tugay as well as agroecosystems such as gardens, orchards, fields, and pastures.
The most effective, standard methods for collecting beetles such as attracting to artificial light sources, shaking down into an entomological umbrella, sweep netting, and rearing of inhabited material were used during the field research. The beetles were studied using an Optek SZM7045-J4L microscope at 7-90× magnifications. Photographs of the cerambycids in nature, their host plants and habitats were taken with Canon EOS 550D, Canon EOS 600D, and Olympus XZ-1 cameras. Produced images were stacked, aligned, and combined using ZERENE STACKER software (www.zerenesystems.com). Geographical coordinates were read off and recorded using Garmin Oregon 550T 3-Inch Handheld GPS Navigator. For each specimen collected, the exact location (including the GPS coordinates), altitude, date, and the names of the collectors are given. Additionally, information on the general distribution and biology of the species are provided. Some general data that had been collected by the first author during long-term field research were also used.

The nomenclature was adopted from the Catalogue of Palaearctic Coleoptera (
The specimens are preserved in the entomological collection of the Department of Natural History of the Upper Silesian Museum in Bytom and in authors’ collections.
During the one-month expedition, a total number of 12 species (approximately 20% of the Tajik cerambycid fauna) belonging to three subfamilies (Prioninae 1 sp., Cerambycinae 10 spp., and Lamiinae 1 sp.) were recorded. The list of recorded taxa along with the new localities, general characteristics, and remarks on the species biology and ecology follow.

Although the species is distributed also in Turkmenistan and Tajikistan, most of the known specimens were collected in the Samarkand region in Uzbekistan. In Tajikistan, it was only observed in the north-western part of the country as far as the southern slope of the Gissar Mountain ridge (
Adults are active from early May to late July. In the hilly area of the Katagurgan environs (Uzbekistan),
The larvae develop in soil, where they probably feed on roots of various plants. According to
According to
In the Sarichashma environs, the specimens were collected in a semi-ruderal plant community (Fig.
Because this site is located directly on the Tajik-Afghan border, it can be expected that this species will also occur in Afghanistan. On the other hand, the bordering Panj River may form a natural migration barrier, particularly for the females, which are probably flightless. It is noteworthy that two other related Prionini species, Miniprionus pavlovskii (Semenov, 1935) and Pogonarthron semenovianum (Plavilstshikov, 1936), were also recorded in the immediate vicinity of the plot mentioned above (
The authors feel compelled to state that this plot is located in a strongly guarded zone just a few kilometres from the Afghan border. No foreigners are allowed to enter this area without the proper permits. Staying in this zone (especially at night) can have serious consequences from both the Tajik authorities and Taliban fighters from Afghanistan due to the large drug route in the region.

The city longhorn beetle A. sarta is a species widely distributed throughout the Palaearctic and the Oriental region. It is believed that it originated in Pakistan and Western India from which it spread to Afghanistan, Iran, and to Central Asia (
The species is polyphagous with a wide range of host plants and it primarily attacks tree trunks. For this reason, the species is considered a serious pest in the countries in which it occurs. In many cities of Central Asia, poplars and willows have been destroyed as well as plane trees, acacias, and ashes in Dushanbe (
It was observed that A. sarta attacks both maximally exposed and shaded trees. The larval feeding grounds (Fig.

It is noteworthy that only one specimen was found despite a few hours of examining the plot using various methods. The presence of only a single female may indicate the end of the period of the occurrence of this species. It appears that T. gromenkoi is endemic to the Gissar Mountains.

This species occurs in Kyrgyzstan, Tajikistan, and Uzbekistan (
Only a single female was observed despite a 24-hour monitoring of the trees on the plot. This may either be related to the end of the period of the occurrence of the species or its hidden life in the treetops.

This species is distributed in the countries of Central Asia and the Xinjiang region of China (
Mating of this species seems to start at the end of June. We observed adults flying into wooden components and actively moving on trunks of the wild apple tree Malus sieversii, where they were also mating. T. pilosum was recorded sympatrically with R. nadari in the same habitat (Fig.

This species occurs in Tajikistan, Uzbekistan, Kyrgyzstan, and Kazakhstan (
A massive mating of this species was observed in the Takob environs between 8 and 10 July. The beetles performed characteristic slow flights during the day. It is noteworthy that no more species of the genera Agapanthia or Phytoecia were caught during the entire expedition, despite the very frequent use of the sweep-netting method in appropriate habitats (e.g. alpine meadows) in various parts of the country. This species seems to occur much later or longer than the other related species.

Knowledge about the fauna of Tajikistan, particularly invertebrates, is still poor. Species of beetles that are new to science are increasingly being described, for example, Kytorhinus kergoati Delobel & Legalov, 2009 (Chrysomelidae) (
Longhorn beetles arouse great interest among beetle families, and therefore the current state of knowledge on Tajik cerambycids appears to be better than that for other groups. However, the knowledge about the species that occur in this country is still insufficient; thus, some new taxa have been described in recent years: Turkaromia gromenkoi (
The distribution of species within the individual subfamilies is characteristic for Central Asia and it is presented as follows: Prioninae (9), Lepturinae (2), Spondylidinae (1), Apatophyseinae (2), Cerambycinae (20), and Lamiinae (25). Species of the subfamily Prioninae, whose larvae develop in soil and feed on plant roots, as well as many representatives of the tribes of Agapanthiini and Phytoeciini (Lamiinae), whose development take place in the stems and roots of herbaceous plants, dominate the fauna of Tajikistan. Representatives of the subfamily Lepturinae are few in number possibly due to the lack of trees and, consequently, small amounts of deadwood, which is quite a normal situation in Central Asia. For example, the total number of Lepturinae species is: 5 (Uzbekistan), 6 (Turkmenistan), 9 (Kyrgyzstan), and 4 (Afghanistan).
Because of the many geographical barriers in Tajikistan, a high level of endemism occurs in this group of beetles. Currently among the 60 taxa, as many as eleven taxa occur exclusively in Tajikistan. The endemics include Mesoprionus zarudnii, Pogonarthron semenovianum (all known specimens were only collected in Tajikistan, near the Afghan border (
Due to its climatic conditions, Tajikistan is a very unique place to collect insects. The flight period of various groups of longhorn beetles is quite diverse. Some species only occur in spring, for example the genus Phytoecia, which is represented here by as many as 13 species. On the other hand, some species of the subfamily Prioninae begin to fly in late summer. There are also many nocturnal species that lead very cryptic lifestyles. For these reasons, comprehensive studies that include the entire growing season are needed to obtain a reasonably full and true picture of the composition of the species of longhorn beetles in this country.
Today, the industrial and economic activities of humans are the most important factors that influence ecosystems. Such anthropogenic activities cause important changes in fauna and flora that lead to the simplification of biogeocenosis structures and to decrease in the differences between landscape zones. Some agrotechnical measures, such as ploughing desert regions of a country, deforestation, intensive irrigation, chemical use, and the development of industry in large parts of southeast Central Asia have induced the development of specific fauna in the anthropogenic landscapes. Among the most important forms of human activity are ploughing and managing soils that had not been used earlier, which causes the formation of secondary biocoenosis and agrocoenosis, which in turn leads to disturbances of the ecosystems and, as a result, to the disappearance of many vulnerable species. Planting trees and shrubs in disturbed regions is extremely important due to their role as an ecological corridor (
