Abstract
Khramov, A.V., Nam, G.-S. & Vasilenko, D.V. 13 December 2019. First long-proboscid flies (Diptera: Zhangsolvidae) from the Lower Cretaceous of South Korea. Alcheringa 44, 160–168. ISSN 0311-5518 Buccinatormyia gangnami sp. nov. (Zhangsolvidae) is the first record of Diptera from the Lower Cretaceous Jinju Formation of the Korean Peninsula. B. gangnami is described based on six specimens, the largest number of fossils known for a single species of Zhangsolvidae. Four specimens of B. gangnami preserve a long proboscis; mouthparts of this species show a twofold variation in relative length, which may be partially explained by sexual dimorphism. B. gangnami is the third known species of Zhangsolvidae with extremely elongate antennal flagella. The preserved abdominal colouration pattern in these fossils suggests that B. gangnami was probably a wasp mimic. Alexander V.
