Pocadius adustus Reitter, 1888

Materials

Examined:

GEORGIA • Nedzvi Managed Reserve; N41.9024°, E43.5161°; 885 m a.s.l.; 08.10.2021; ISU, CaBOL IDs: 1018762, 1018763 (Fig. 4 ); leg: CaBOL team.

Genetics:

The BOLD identification engine indicated high similarity of the sequence yielded from the specimen with CaBOL ID 1018763 (BOLD: ACJ7127) to the COI of Pocadius adustus from Germany (BIN ID: ACJ7127, similarity 98.95%). The morphology of the Georgian specimens also perfectly corresponds to the description provided in the key by Medvedev (1965).

Remarks:

To date, 63 species of Nitidulidae comprising 23 genera are known from Georgia ( Jelinek and Audisio 2007; Tarkhnishvili et al. 2013). The genus Pocadius includes 10 described species, displaying peculiar habits of being epigeous gasteromycetes specialists ( Cline 2008). P. adustus has a wide distribution range in the Palaearctic region, with the nearest findings from Turkey ( Jelinek and Audisio 2007) and the Western Caucasus in Russia ( Cline 2005). The specimens from the Nedzvi Managed Reserve found in the puffball ( Lycoperdon sp.) cavity represent a first record for Georgia.
