Abstract

A new fossil genus and species of Cantharidae, Li, Biffi, Kundrata & Cai , is reported from mid-Cretaceous Burmese amber. The new species is tentatively attributed to the extant subfamily Malthininae based on a combination of characters, including the symmetrical apical maxillary palpomeres, shortened elytra, pronotum with arched margins and well-defined borders, tibiae with apical spurs, and tarsal claws simple, although its well-developed gonostyli are atypical in Malthininae. The discovery of also suggests a possible Gondwanan origin for Malthininae.

摘要

从白垩纪中期的缅甸琥珀中发现了花萤科的一个新化石属和新物种，李、比菲、昆德拉塔和蔡报道了这一发现。基于包括对称的上颚顶端节、缩短的鞘翅、边缘呈拱形且边界清晰的前胸背板、具顶端距的胫节以及简单的跗爪等一系列特征组合，这个新物种暂时被归入现存的花萤亚科，尽管其发育良好的生殖突在花萤亚科中并不典型。该发现还表明花萤亚科可能起源于冈瓦纳大陆。
