Burmorussidae, a new family of parasitic wasps (Insecta: Hymenoptera) from mid-Cretaceous Burmese amber

Zhang Qi, Kopylov Dmitry, Rasnitsyn Alexandr, Zheng Yan & Zhang Haichun
A new genus and species, Burmorussus mirabilis, is described based on two specimens from the mid-Cretaceous Burmese amber, and considered to be a specialized parasitic wasp of wood-living hosts. The new taxon is characterized by an orussid-like ocellar crown, big eyes, antennae attached well above the clypeus, and antennal grooves or ventral transverse frontal carinae absent. Additionally, all legs carry a prominent lanceolate lobe on the 3rd tarsomere. A similar structure is found, but organized...

Evaluating the genetic variation of the COI gene of Insecta: Implications for DNA barcoding, metabarcoding and species delimitation studies

Haiguang Zhang & Wenjun Bu
The genetic variation of the COI gene has a great effect on the final results of the species delimitation studies. However, little research has comprehensively investigated the genetic divergence in COI among Insecta. The fast-growing COI data in BOLD provide an opportunity for comprehensively appraising the genetic variation in COI among Insecta. We calculated the K2P distance of 64,414 insect species downloaded from BOLD. The match ratios of the clustering analysis based on different thresholds...
