Abstract

Abstract. An unusually large acariform mite is described as Immensmaris chewbaccei gen. et sp. nov. from the Cretaceous (ca. 100 Ma) Burmese amber of Myanmar. With an idiosoma plus gnathosoma more than a centimetre long, it represents the largest unequivocal fossil mite ever recorded and approaches the maximum size of the largest living Acariformes today. Although some details of the dorsal idiosoma are equivocal, the new fossil appears to belong to Smarididae (Prostigmata: Parasitengona: Erythraeoidea) and also represents the largest erythraeoid mite ever discovered, indicating a clade of giant, possibly arboreal, mites in the Late Cretaceous of southeastern Asia.

白垩纪缅甸琥珀中的巨型螨虫

摘要缅甸白垩纪(约100 Ma)缅甸琥珀中的一种异常大的针状螨被描述为imunsmarischewbacei gen. et sp. 11 .。它有一个超过1厘米长的独特体和颌体，代表了有史以来最大的明确化石螨，接近当今最大的活螨的最大尺寸。虽然背部特有体的一些细节尚不清楚，但新化石似乎属于Smarididae (prostimata: Parasitengona:Erythraeoidea)，也代表了迄今为止发现的最大的erythraeoid螨，表明东南亚晚白垩世的一个巨大的，可能是树栖的螨类。
