Abstract
Ptinidae is currently a diverse family of beetles with a sparse Mesozoic fossil record. Here a new ptinid fossil, Granulobium whitei Li, Philips & Cai gen. et sp. nov., is reported from midCretaceous Burmese amber, which represents the earliest record of the extant subfamily Eucradinae. Granulobium can be recognized within Eucradinae by its coarsely granulated pronotum with no carinae or ridges, narrowly separated procoxae, irregularly punctate elytra, and relatively short abdominal ventrite 4. Our discovery indicates that Mesozoic Ptinidae were more biodiverse than previously appreciated.
飞虫科目前是一个多样化的甲虫科，中生代化石记录很少。本文报道了在中白垩世缅甸琥珀中发现的一种新的蜡质类化石Granulobium whitei Li, Philips & Cai gen. et sp. nov.，它代表了现存Eucradinae亚科的最早记录。细粒菌在Eucradinae科中可被识别为粗粒状的前凸部，无隆突或脊，前凸部间距狭窄，鞘翅不规则点状，腹内腔相对较短。我们的发现表明，中生代栉蚊科的生物多样性比以前认识到的要多。
