Abstract:
Ips subelongatus (Coleoptera, Scolytinae) is an important bark beetle species that infests Larix spp. in Asia.
Individuals of this beetle are vectors of ophiostomatoid fungi, on their exoskeletons, that are transmitted to infested
trees. In this study, the symbiotic assemblage of ophiostomatoid fungi associated with I. subelongatus in Northeast China
was studied. Fungal isolates were identified based on their morphological characters and sequences of ITS, beta-tubulin,
elongation factor 1-alpha and calmodulin gene regions. In total, 48 isolates were collected and identified, residing in six
taxa. These included a novel species, described here as Ophiostoma gmelinii sp. nov.
