Review of the genus (Hemiptera, Heteroptera, Miridae).

The genus Kerzhner, 1962 is revised, with differential diagnoses and redescriptions provided for nine species. Three distinct species groups were recognized within the genus: group (, , , ), group (, , ), and group (, ). A key to species, illustrations of dorsal habitus, male and female genitalia, and selected diagnostic structures are included.

Note on the genus (Xylariaceae) - first records and a new species of the genus from Iran.

In a survey of xylarialean fungi in northern Iran, some specimens attributable to the genus were collected, cultured and sequenced. Morphological evidence and phylogenetic analyses of a combined ITS, LSU, and gene dataset confirmed the presence of and in Iran for the first time. Furthermore, the new species , which shows similarities to and its putative synonym , but significantly differs from the latter in its DNA sequences, was encountered.
