Gyascutus fulgidus
Gyascutus fulgidus is a species of metallic wood-boring beetle in the family Buprestidae, originally described by Barr in 1969. The species is native to western North America, particularly the Great Basin region. Based on genus-level characteristics, adults are known to possess a pale yellow-white waxy bloom on the elytra, which is believed to serve a thermoregulatory function in these desert-dwelling insects. The species has been collected on willow (Salix) in western Nevada.
