The tiger beetles of the southern Levant (Egypt: Sinai, Israel, Jordan) and adjacent regions of the neighboring countries Lebanon, Syria, Iraq, Saudi Arabia and Egypt are reviewed in terms of species taxonomy, ecological and distributional traits and conservation biology. An illustrated dichotomous identification key from the species of this region is provided. Based on the classical identification key, we developed a digital identification application for smartphones and tablets. The species status of Calomera aulicoides (J.R. Sahlberg, 1913) is (re-) established (stat. rest.) as this taxon can be found sympatrically and parapatrically together with Calomera littoralis winkleri (Mandl, 1934). Morphological character states are discussed to identify Cicindela javetii Chaudoir, 1861 and C. herbacea Klug, 1832. Calomera aphrodisia (Baudi di Selve, 1864) is recorded for the first time from Israel. The presence of Calomera aulica (Dejean, 1831) and Grammognatha euphratica (Dejean, 1822) is confirmed by new records. At least five taxa are threatened or extinct in Israel. For one of these species, Israel has a national responsibility for the conservation as the main part of the distribution range is within this country.

As tiger beetles are often colorful and diurnal, they have attracted the attention of academics, citizen scientists, and nature-lovers. For example, there is an entire journal ‘Cicindela’ devoted exclusively to this group, and highlights the public interest in these animals which belong to the best known insects (
For many regions, updated identification keys, compilations or even field guides for the tiger beetles are available, e.g. for North America, Australia, parts of China, most parts of Europe and Sub-Saharan Africa (
(1) In the faunistic part of their work
(2) An identification key which includes the species of the adjacent countries would be useful. To meet the need of many enthusiasts and laypersons, for example in Facebook groups which discuss entomology, we present a field guide for mobile devices, such as smartphones and tablets (cf.
(3) Open systematic questions, for example, the systematic rank of the two parapatric and sympatric “subspecies” of the Cicindela littoralis group in the southern Levant, need to be revised.
(4) Finally, as claimed by both taxonomists and conservationists (e.g.
We define the southern Levant as a section of Southwest Asia comprised of the Sinai Peninsula (Egypt), Israel (including areas under Palestinian control), and Jordan. Species known from surrounding regions in Egypt, Lebanon, Syria, Iraq and Saudi-Arabia are also considered. For an overview of the study area see Fig.
We rank the tiger beetles as a family within the Geadephaga. In many other systematic compilations of Adephaga, tiger beetles are ranked as a subfamily of Carabidae (e.g.
Since
Moreover there are differences in the rank of species and subspecies between many authors (
This study is based on the examination of specimens collected during the authors’ field trips in Egypt, Israel, and Jordan, as well as specimens stored in entomological collections (including material from Europe, Africa, and other parts of Asia for comparisons). We studied approximately 2,000 specimens stored in the following collections:
CAL Working collection Assmann, Lüneburg, Germany (part of ZSM)
CGD Working collection Gebert, Dresden, Germany
COQ Working collection Orbach, Qiryat Tiv’on, Israel (will be transferred to SMNHTAU, Israel)
CSW Working collection Starke, Warendorf, Germany (will be transferred to Westfälisches Landesmuseum Münster, Germany)
CSH Working collection Schnitter, Halle/S., Germany
CWB Working collection Wrase, Berlin, Germany (part of ZSM)

For detailed explanations about measurements, photography, traits and distributional data see other publications about the carabid beetles of the southern Levant (
As few biologists and citizen scientists work on tiger beetles in the Middle East, our data do not allow for the estimation of a trend for all species. Thus, we used the approach of
If large parts of the distribution range (>67 %) of a taxon are in the study region we derive the national responsibility of the given states for the preservation of the given taxa (cf.
We developed two tools for the identification of the tiger beetles in the southern Levant:
(a) A “classical”, dichotomous identification key (
(b) An Android application for mobile phones and tablets (Android Studio environment: Google and Alliance 2016, Android Homepage). Text and figures are adopted from the “classical” identification key.
In general, tiger beetles differ from all other ground beetles in the position of antennae which insert on the frons of head, between the bases of mandibles (Fig.
Tiger beetles are agile, usually diurnal beetles with a head (including the eyes) wider than the pronotum; long, thin legs and long, sickle-shaped mandibles with long, simple teeth along the inner edge of the mandibles (Figs

For ease of orientation, the numbering schemes of the species found in the identification key and in the species accounts are identical. Species which are known from adjacent countries, but not from the southern Levant itself are given in parentheses.
The following species are also not incorporated in the key: 30. Cylindera pygmaea (Dejean, 1825), 31. Calomera caucasica (Adams, 1817), the Salpingophora species 32. S. bellana (W. Horn, 1905), 33.

The above presented key for the tiger beetles of the southern Levant and adjacent territories is also available as a stand-alone application (app) for portable Android devices (Android-version 5.0 and later releases; Application Programming Interface (API) of 21 or higher is recommended), and can be downloaded from https://doi.org/10.3897/zookeys.734.21989.suppl1. On most devices, the app requires less than 150 Mega bytes (MB) of storage.
After the loading screen, the users will first see a short morphological definition of cicindelids and drawings of the external morphology with key terms indicated (see above). The next screen leads to the dichotomous identification key and to the species list. All photographs and most of the drawings have a zoom function which enables viewing at a higher resolution. Each species name is linked to the species’ accounts with information about habitat, distribution and conservation status (shortened version of the species accounts given below). Here too, a habitus photograph which can be enlarged allows for better orientation and helps to verify identification to species level. The species list is probably be more helpful for experienced users, while beginners should start with the identification key. Figure
All species are macropterous and flight active. If the species are not recorded from the southern Levant, or if not enough data about the populations during the last decades are available, no conservation information is given.

Although the taxon goudotii (Dejean, 1829), which occurs along the coasts of the western Mediterranean, is currently ranked as a subspecies of C. littorea, it is probably a valid species. Cephalota littorea s.str. and goudotii do not occur parapatrically as their ranges are separated from each other by a gap which is partially filled by the distribution range of tibialis. Moreover, the differences in the median lobe of the aedeagus (shape, internal sac) may support the species status of both goudotii and littorea (but see C. aulicoides for discussion of genital structures as characters to delineate species).

Three species are listed from the southern Levant, but their occurrence is questionable as verifiable records are missing: Calomera fischeri, Cephalota circumdata and Cephalota deserticola.
We present two formats of the same key which enables the identification of the tiger beetles of Egypt, western Iraq, Israel (including the areas under Palestinian control), Jordan, Lebanon, Syria (without the easternmost parts) and northern Saudi Arabia. In the investigated study region, the southern Levant, there are Geadephaga species for which poleward shifts in their distribution ranges due to global change have been identified (e.g.
Under laboratory conditions, all species can be reliably identified using the “classical” identification key, including those requiring the dissection of the male genitalia (e.g. sibling species Cicindela javetii, C. herbacea; Calomera aulicoides, C. littoralis, and C. aulica). However, the majority of the species can be identified correctly under field conditions, by examining live individuals using basic magnification tools. In such circumstances the Android application may be more useful rather than the classic key. We hope that both identification tools will be useful in a range of contexts, such as education at levels, academic research, the activities of citizen scientists and in practical conservation work like surveying.
Our application for mobile Android devices, TIGER BEETLES ID, can serve as a starting point for the development of additional tools, with the translation of the app’s text into both Hebrew and Arabic being greatly desired. Moreover, a simple version of the identification application is possible by deleting those alternatives considering the species which occur exclusively outside of Israel, the areas under Palestinian control, and Jordan. The simplified version may better address the need of less experienced users such as biology teachers at secondary schools and their students. For this version, appropriate translations of morphological terms (for example genae, palpi, etc.) must be taken into consideration, and in some cases may need to be developed, as established terms in Hebrew and in Arabic are in many cases lacking.
As far as we know, the first record of Calomera aphrodisia for Israel has now been documented in the form of an old specimen in ZISP. The occurrence of two species is confirmed by new records from Jordan (Grammognatha euphratica and Calomera aulica). It is likely that additional species which occur in Jordan have not yet been recorded (e.g., Cephalota vartianorum in the vicinity of the Dead Sea, see also below), especially as the oases in the eastern part of the country have, to our knowledge, not yet been sampled.
In terms of tiger beetle faunistics, Israel is certainly the best-studied country in the Middle East, as shown by the number of records found in SMNHTAU which are listed by
For the classification of threatened species, we used an approach which is widely used in Central Europe (
Five tiger beetle species have been classified as threatened. Two species, Grammognatha euphratica and Calomera aulica, are defined as vulnerable, meaning that they have become rare in Israel, and probably in Jordan as well. However, both taxa are widely distributed outside of the southern Levant and seem not to be threatened in other parts of their distribution ranges. Grammognatha euphratica is apparently expanding its distribution range northwards (
Three critically endangered species have not been recorded in Israel during the last decade.
(a) Cephalota vartianorum, for which apparently suitable habitats remain in the salt marshes on both the Israeli and on the Jordanian sides of the Dead Sea. However, this species seems to have disappeared from nature reserves where it was recorded in 1994 (e.g. Enot Zuqim), as we did not find individuals in any of our collecting trips, including nocturnal light trapping methods. Specifically in Enot Zuqim, a decline of the phytodiversity in this nature reserve has been reported (
(b) The known habitat of Cicindela javetii in the Golan Heights has been destroyed, and no further records since the 1990s are known from Israel. Due to the high power of dispersal of the species, with all individuals being fully winged and flight-active, (re-) colonization of suitable habitats in the southern Levant is possible.
(c) Israel and Egypt are responsible for the world-wide preservation of Cylindera contorta valdenbergi, as its entire distribution range is confined to these two countries. However, it is unclear if populations of this taxon still exist, or if C. contorta valdenbergi is extinct. The definition of national responsibility is important in the assessment of national conservation priorities as well as in decision making about inclusion in international conventions on species conservation. The larval development of Cylindera contorta valdenbergi occurs in close proximity to sea water line on beaches, a habitat which is often extremely disturbed by tourism and recreational activities such as swimming facilities and off-road vehicles which compress the soil and sand and destroy the habitat of the species. For Habroscelimorpha dorsalis s.str. Say (= Cicindela dorsalis s.str.), an endangered species covered by the U.S. Endangered Species Act (
We hope that our identification tools and the species’ accounts describing the ecology and conservation biology of the tiger beetles of the southern Levant will encourage further work on tiger beetles in the Middle East and enhance the conservation and preservation of these attractive insects.
