A New Species

A new species of the staphylinid subfamily Oxytelinae is described and figured from a series of well-preserved compression fossils of the Yixian Formation (Early Cretaceous), Beipiao City, Liaoning Province, northeastern China. The species is placed in the recent genusAnotylusThomson, 1859 based on typical morphological features for the genus as well as secondary sexual characters. The strong projection of the anterior pronotal angles is a feature also possessed by males of several recent Neotropical taxa in the genus. This is the earliest fossil rove beetle with clearly demonstrable sexual dimorphism.

AbstractA new species of the extinct rove beetle genus Hesterniasca Zhang, Wang & Xu, 1992 is described and illustrated on the basis of a well-preserved specimen from the Lower Cretaceous Yixian Formation at Huangbanjigou of Beipiao City, Liaoning Province, Northeastern China. Based on the examination of this new species that is preserved better than the type species of the genus, Hesterniasca is firmly placed in the recent subfamily Tachyporinae, tentatively in the recent tribe Tachyporini MacLeay, 1825. Arguments for the Early Cretaceous age of the Laiyang Formation in Shandong Province, Eastern China, from where the type species of the genus, Hesterniasca obesa Zhang, Wang & Xu, 1992, has been discovered are provided.

A new genus Mirabythus Cai, Shih et Ren, gen. nov. (type species, M. lechrius Cai, Shih et Ren, sp. nov.) and M. liae Cai, Shih et Ren, sp. nov. from the family Scolebythidae are described from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, northeastern China. These findings extend the existence of Scolebythidae to the Early Cretaceous of China, while providing evidence to support Engel and Grimaldi’s hypothesis that the family was widely distributed throughout the Cretaceous. Our two new species with clear venation also provide a comprehensive understanding of the venational changes from the Early Cretaceous to now. A key to the fossil and extant genera of Scolebythidae is provided.

A New Species

A new genus with a new species (Shoushida regilla gen. et sp. nov.) of pelecinid wasps is described and illustrated. The fossil has been collected from the Upper Jurassic to Lower Cretaceous of Yixian Formation at Huangbanjigou Village, Liaoning Province, China. The new species has vein Rs forking to two branches: Rs 1 straight and reaching wing margin much before apex and Rs 2 long, forming an “X” pattern together with 2r-rs. This finding represents the earliest fossil record of subfamily Pelecininae in the world up to date. Sexual dimorphism in Pelecinidae is briefly discussed.

A New Species

An unusual new omaliine species, Anthobium alekseevisp. nov., is described and illustrated from Eocene Baltic amber, tentatively placed in the megadiverse genus Anthobium Leach, 1819. A new monotypic species-group is established. The new species can easily be distinguished from other species of the genus by the larger body, shape of the subrectangular pronotum, and the presence of a median carina on the prosternum and large, subtriangular tooth on the inner side of each mesotibia, likely exhibiting a peculiar sexual dimorphism in the male. Based on the study of the specimen with support of microtomographic images, a brief comparative analysis of a new species with described extant species of Anthobium is provided.

The tribe Diglottini Eichelbaum, 1909 comprises two halophilous rove beetle genera Diglotta Champion, 1899, and Paradiglotta Ashe & Ahn, 2004. The tribe contains eight known species distributed in the Nearctic and West-Palaearctic regions, and also Fiji Islands and New Zealand. This tribe is recorded for the first time from South America with the description of a new species, Diglotta brasiliensis n. sp. from southern Brazil (Paraná). Characters of the mouthparts, aedeagus and spermatheca of the new species are illustrated and compared with other Diglotta species. Sexual dimorphism is reported for the first time in the genus.

A new species of the family Prophalangopsidae, Ashanga borealis sp.n., is described from the Lower Cretaceous Yixian Fomation (Liaoning Province, P.R. China). The male forewing of the new species is similar to that of the Middle/Upper Jurassic species Ashanga clara Zherikhin 1985, but differs from it in possessing a forewing arched anterior margin, RS branching more basally, and MP + CuA1 with more branches. The fossil record of Chifengiinae is reviewed.

The first skiff beetle fossil and earliest myxophagan,Hydroscapha jeholensisn. sp., is described and illustrated on the basis of a single specimen from the Lower Cretaceous Yixian Formation at Huangbanjigou of Beipiao City, Liaoning Province, Northeastern China. Based on the combination of diagnostic characters of this specimen (e.g., minute and fusiform body, short elytra, tapered abdomen, separated meso- and metacoxae, and 3-segmented tarsi), we suggest that it is a definitive representative of Hydroscaphidae belonging to the widespread hydroscaphid genusHydroscaphaLeConte, 1874. It also represents the only impression fossil of the beetle suborder Myxophaga. This find displays great significance for shedding light on the preservation of the minute aquatic beetles, since it is the first well-preserved impression fossil reported for the suborder, rather than amber inclusion.
