Abstract
A list of 18 species of checkered beetles is given, together with images of voucher specimens and a distribution map based on literature,
dry collections and databases.
Key words
CaBOL, fauna, Insecta, occurence data
Introduction
Checkered beetles (Coleoptera: Cleridae) are a member of
the superfamily Cleroidea, with about 3,500 species de-
scribed worldwide. Most often, checkered beetles are found
on owers in moist and sunny environments or under tree
barks (McNamara 1991). Checkered beetles mainly repre-
sent phytophagous animals, although there are also zooph-
agous forms known, and some species feed on animal car-
casses (e.g., Trichodes apiarius (Linnaeus, 1758) is known as
a scavenger of bee hives).
Knowledge of checkered beetle diversity in Georgia remains
poor. One of the rst lists of Caucasian checkered beetles pub-
lished by Radde (1899) reported four species for Georgia. Lat-
er on, Zaitsev (1915) updated the list for the country to 16
species. Lastly, Japoshvili et al. (2022) provided three species
of Cleridae from the Lagodekhi Protected Areas. So far, 18
species have been reported from Georgia (Tarkhnishvili et al.
2013). However, species distribution data as well as actual spe-
cies diversity are still very sporadic and incomplete.
Here we comprehensively summarize the existing data
for the checkerid beetle species found in Georgia and pro-
vide new occurrence data for some of the species.
Materials and mathods
Various published articles and online databases for beetles
in the Caucasus and Georgia were checked. e curated
databases GBIF (Global Biodiversity Information Facility)
(GBIF Secretariat 2023) and GBD (Georgian Biodiversity
Database) (Tarkhnishvili et al. 2013) were used for collect-
ing occurrences. Dry entomological collections of the Insti-
tute of Zoology of Ilia State University (ISUZI) were stud-
ied for old, unpublished material. Data used from GBIF
and CaBOL (Caucasus Barcode of Life) (https://ggbc.eu/
data) is cited in the given paper using unique IDs. Identi-
cation of CaBOL material was performed using the identi-
cation keys of Richter (1965) and Krivolutskaya (1992).
In Georgia, social media proved to be a useful tool for
collecting biodiversity data (Iankoshvili and Tarkhnishvili
2021). We used the Facebook page “Wildlife of Georgia” as
a complementary source (WGFB) as well as the internation-
al citizen science platform iNaturalist (https://inaturalist.
ca/) to retrieve the data. For several records, we were unable
to retrieve the collecting date as it was not specied in the
publication, nor did we have access to the actual material.
e taxonomy was validated using GBIF.

e locations for the beetles recorded in older articles are
not precise, in which case the sampling locations were geo-
referenced using Google Earth Pro (v.7.3.6) with varying
accuracy (Fig. 1).
Abbreviations for collecting methods are as follows: HC
= Hand Collection; SwN = Sweeping Net. e genera and
species in the checklist are listed alphabetically. Taxonomy is
according to the Catalogue of Palaearctic Coleoptera (Löbl
and Rolcik 2007). For species with vague occurrence data,
we used “location is not dened”.

Discussion
So far, the species-occurrence records were obtained mostly
from the central part of Georgia. Still, the surveyed area in
Georgia is very sporadic and patchy (Fig. 1). Most of the
parts of the country need to be further studied to provide
comprehensive distributional data for the members of the
Clerida family.
Two of the species given in the checklist, Clerus mutillar-
ius and Dermestoides sanguinicollis, were recorded in Geor-
gia; however, there is no exact data about their localities.
ey were included in the checklist since the Catalogue of
Palaearctic Coleoptera (Löbl and Rolcik 2007) indicates
their presence in the area. Nevertheless, further research is
needed to conrm their occurrence in Georgia.
In addition to the listed species, some others that are
known to occur in the neighborhood of Geogia are ex-
pected to be discovered here too. For instance, Trichodes
sipylus (Linnaeus, 1758) is distributed in Armenia, Azerbai-
jan, and Turkey (Zaitsev 1915; Löbl and Rolcik 2007); T.
ephippiger (Chevrolat, 1874) and T. longissimus (Abeille de
Perrin, 1881) are distributed in Turkey (Bulak et al. 2012);
T. persicus Kraatz, 1894 is distributed in Armenia, Azerbai-
jan (Zaitsev 1915; Löbl and Rolcik 2007), with the closest
occurrence recorded in Gyumri (Armenia) (Slieker et al.
2023). us, all these species are also expected to be found
in Georgia. Nevertheless, targeted research on checkered
beetles in Georgia would uncover the yet-unknown diversi-
ty and distribution patterns of this taxon.

First records of two species of beetles (Insecta, Coleoptera), namely Pocadius adustus Reitter, 1888 (Nitidulidae) and Byrrhus pustulatus (Forster, 1770) (Byrrhidae) are given for Georgia. In addition, an update on the occurrences of Necrobia violacea (Linnaeus, 1758) (Cleridae), Coelostoma orbiculare (Fabricius, 1775) (Hydrophilidae) and Lycoperdina succincta (Linnaeus, 1767) (Endomychidae) are also presented based on the specimens collected in Samtskhe-Javakheti region, determined by morphological and mtDNA barcoding methods.

During this survey, 195 species of coleopterans have been recorded from the Lagodekhi Protected Areas (LPA). Thirty families are recorded for the first time from this area, of which Rhysodidae, Sphindidaeand, and Thymalidae are new for Georgia. One hundred fifty-seven species are new to LPA and 66 of them are new country records.

A previously unreported population of Salicornia europaea has been found on the edges of a small tidal inlet in the emirate of Umm al-Qaiwain. It appears to be different from two ecotypes of the species found in other parts of the United Arab Emirates (UAE). The location has large numbers of an introduced halophytic plant species, Sesuvium portulacastrum, which serve to inhibit the growing of local species. The number of plants of the local S. europaea ecotype is low and the species may disappear. The eradication of the alien species of S. portulacastrum from the area is necessary to protect the S. europaea ecotype and other local flora in the area.

This study is based upon material of the family Cleridae collected from different localities in Turkey between 1971 and 2010. A total of 15 species belonging to three subfamilies (Tillinae, Clerinae, Korynetinae) were recorded from Turkey. Further new localities are included for some species which have already been reported for Turkey. Within these species, Trichodes quadriguttatus ADAMS, 1817 and T. sipylus (LINNAEUS, 1785) has been found the most common and widespread species. Zusammenfassung Diese Studie basiert auf Material aus der Käferfamilie Cleridae, welches von verschiedenen Lokalitäten in der Türkei zwischen 1971 und 2010 gesammelt wurde. Insgesamt konnten 15 Arten aus den Unterfamilien Tillinae, Clerinae und Korynetinae berücksichtigt werden. Von diesen Arten sind Trichodes quadriguttatus ADAMS, 1817 and T. sipylus (LINNAEUS, 1785) die häufigsten und weit verbreitetsten Arten. 325

Twentytwo snake species are recorded for Georgia. Over three years (2017-2019), social media (Facebook, iNaturalist and Instagram) was inspected to identify new snake records for Georgia. This led to an increase in the total number of known snake locations by 78% and this gain led to considerable growth of the Extent of Occurrence (up to 269%) and Area of Occupancy (up to 188%) data. The new locations identified by professional and amateur zoologists correlated with the number of locations known from scientific publications. In contrast, occasional sightings reported in social media only weakly correlated with published data, providing valuable information on highly mobile snakes of the family Colubridae, for which observation by professional herpe-tologists' are disproportionately rare. The study helped improve our knowledge of the range of individual species substantially. Specifically, a number of Colubridae known before only from eastern Georgia were recorded in suitable habitats in the country's western part. There were significant gains in knowledge for Elaphe dione, Zamenis hohenackeri, Hemorrhois ravergieri, and Vipera eriwanensis. Because IUCN categories for reptiles are dependent on the size and shape of their ranges, this information is highly useful for planning the conservation priorities for snakes in the country.
