Abstract

A new genus and species, Creapsilocephala nagatomii gen. et sp. nov. assigned to the enigmatic family Apsilocephalidae, was described from Mid-Cretaceous Burmese amber. The details of mouthpart structures in the new species are well preserved, revealing the non-piercing mouthparts that comprise an elongated labrum and tube-like hypopharynx, a pair of slender pointed laciniae, one-segmented palp, and prolonged labium. According to the analysis of mouthpart features, the food tube of the new species is constituted by the labrum and hypopharynx, which supports a nectar-feeding habit. This new finding enriches the species diversity of Cretaceous Apsilocephalidae and enhances the knowledge of the early biological features in this family.

白垩纪中期缅甸琥珀中发现的具有拉长口器的 Apsilocephalidae (Asiloidea) 新属和新种
从中白垩世缅甸琥珀中描述了一个新属和新种Creapsilocephala nagatomii gen.该新种的口器结构细节保存完好,揭示了由拉长的唇瓣和管状下咽、一对细长的尖唇瓣、单节腭和延长的唇瓣组成的非穿刺口器。根据对口部特征的分析,该新种的食管由唇瓣和下咽构成,支持其采蜜习性。这一新发现丰富了白垩纪栉水母科的物种多样性,加深了对该科早期生物学特征的认识。
