Abstract: A remarkable new genus and species of Nevrorthidae, Sisyroneurorthus aspoeckorum gen. et sp. nov., is described from mid-Cretaceous Kachin amber of northern Myanmar. This new species is the second Mesozoic representative of Nevrorthidae. The distal fusion of ScP and RA in the forewing of this new genus is shared by most Sisyridae. Given the probable sister-group relationship between Nevrorthidae and Sisyridae, our study sheds light on the evolution and morphological diversity of Nevrorthidae in the Mesozoic era.

Character analysis and descriptions of Eocene sphodrine fossils (Coleoptera, Carabidae) using light microscopy, micro-CT scanning, and 3D imaging https://dez.pensoft.net/article/79931/ Deutsche Entomologische Zeitschrift 69(1): 19-44

DOI: 10.3897/dez.69.79931

Authors: Joachim Schmidt, Stephan Scholz, Kipling Will

Abstract: Of the 12 specimens of Calathus-like sphodrine beetles presently known from Baltic and Rovno amber deposits, 11 specimens were investigated using light microscopy, micro-CT scanning, and 3D imaging techniques. For the first time, many significant diagnostic characters of the external morphology and male and female genitalia of Eocene Sphodrini were studied in detail. Based on these data, three fossil species are diagnosed and placed in a natural group characterized by a derived pattern in elytral chaetotaxy and microsculpture and therefore the genus Quasicalathus Schmidt & Will, gen. nov. is described to comprise these species. Due to the presence of a styloid right paramere, Quasicalathus gen. nov. is considered a member of the sphodrine “P clade” of Ruiz et al. (2009). However, given the absence of synapomorphies of any species group of the P clade, the systematic position of Quasicalathus gen. nov. within this clade remains unresolved. The Baltic amber species Calathus elpis Ortuño & Arillo, 2009 is redescribed based on additional, fossil, non-holotype material and transferred to Quasicalathus gen. nov. Identification of the additional C. elpis fossil material remains slightly uncertain due to the non-availability of the holotype for direct comparison coupled with doubts regarding the accuracy of certain character states presented in its original description. Two species are newly described: Quasicalathus agonicollis Schmidt & Will, sp. nov., from Baltic amber, and Q. conservans Schmidt & Will, sp. nov., from Rovno amber.

Phylogeny and age of cockroaches: a reanalysis of mitogenomes with selective fossil calibrations https://dez.pensoft.net/article/68373/ Deutsche Entomologische Zeitschrift 69(1): 1-18

DOI: 10.3897/dez.69.68373

Authors: Xin-Ran Li

Abstract: In spite of big data and new techniques, the phylogeny and timing of cockroaches remain in dispute. Apart from sequencing more species, an alternative way to improve the phylogenetic inference and time estimation is to improve the quality of data, calibrations and analytical procedure. This study emphasizes the completeness of data, the reliability of genes (judged via alignment ambiguity and substitution saturation), and the justification for fossil calibrations. Based on published mitochondrial genomes, the Bayesian phylogeny of cockroaches and termites is recovered as: Corydiinae + (((Cryptocercidae + Isoptera) + ((Anaplectidae + Lamproblattidae) + (Tryonicidae + Blattidae))) + (Pseudophyllodromiinae + (Ectobiinae + (Blattellinae + Blaberidae)))). With two fossil calibrations, namely, Valditermes brenanae and Piniblattella yixianensis, this study dates the crown Dictyoptera to early Jurassic, and crown Blattodea to middle Jurassic. Using the ambiguous ‘roachoid’ fossils to calibrate Dictyoptera+sister pushes these times back to Permian and Triassic. This study also shows that appropriate fossil calibrations are rarer than considered in previous studies.

New species of Omma Newman from mid-Cretaceous Burmese amber (Coleoptera, Archostemata, Ommatidae) https://dez.pensoft.net/article/74174/ Deutsche Entomologische Zeitschrift 68(2): 341-348

DOI: 10.3897/dez.68.74174

Authors: Yan-Da Li, Di-Ying Huang, Chen‑Yang Cai

Abstract: A new fossil species of the extant archostematan genus Omma Newman, O. forte sp. nov., is reported from mid-Cretaceous amber from northern Myanmar. The extinct ommatid genus, Cionocups Kirejtshuk from the same deposit, is considered as a junior synonym of Omma, and C. manukyani is transferred to Omma, as O. manukyani comb. nov. A key to species of Omma from Burmese amber is also provided.

Limnomma, a new genus of Ommatidae from the Middle Jurassic Daohugou beds (Coleoptera, Archostemata) https://dez.pensoft.net/article/71880/ Deutsche Entomologische Zeitschrift 68(2): 299-308

DOI: 10.3897/dez.68.71880

Authors: Yan-Da Li, Erik Tihelka, Hong Pang, Di-Ying Huang, Chen‑Yang Cai

Abstract: The relictual archostematan beetle family Ommatidae attained high diversity during the Mesozoic. Despite their once high taxonomic diversity and morphological disparity, many Mesozoic ommatid taxa remain poorly understood, partly due to limited preservation. Here we report an exceptionally well-preserved fossil, which we describe as a new ommatid genus and species, Limnomma daohugouense gen. et sp. nov., from the mid-Jurassic Daohugou Lagerstätte in Northeast China. The new genus can be most easily distinguished from other ommatids by the presence of a circular non-tuberculate region on ventrite 5. The new taxon is discussed in relation to the classification of the Mesozoic genera Brochocoleus and Burmocoleus.

New findings of Flagellisargus J Zhang, 2012 (Diptera, Brachycera, Archisargidae), with discussion of the placements of some controversial taxa https://dez.pensoft.net/article/13550/ Deutsche Entomologische Zeitschrift 64(2): 111-122

DOI: 10.3897/dez.64.13550

Authors: Junfeng Zhang

Abstract: A new species of a new subgenus and a similar known species referred to the genus Flagellisargus J Zhang, 2012 are described and illustrated based on a male and a female impression fossils of these flies: Flagellisargus (Changbingisargus) parvussubgen. et sp. n. and Flagellisargus (Flagellisargus) cf. sinicus J Zhang, 2012. The latter taxon is the first record of a female Flagellisargus. Recently taken out of Archisargoidea, this study concludes that Flagellisargus should be an archisargid genus based on the known (male) and new (female) impression fossils. The placement of Daohugosargus J Zhang, 2012b is reassessed. It demonstrates close similarities in body structure and wing venation to archisargid flies, and can be retained as an archisargid genus. Archirhagio mostovskii J Zhang, 2015 is separated from Archirhagio zhangi K Zhang et al., 2009. Helempis Ren, 1998 could be, as a separate genus, placed in Archisarginae, Archisargidae.

On the enigmatic Sinonemestrius Hong & Wang, 1990, with description of a new species based on a complete fossil fly (Diptera, Brachycera, Tabanomorpha, Heterostomidae) https://dez.pensoft.net/article/11724/ Deutsche Entomologische Zeitschrift 64(1): 61-67

DOI: 10.3897/dez.64.11724

Authors: Junfeng Zhang

Abstract: A new species of Sinonemestrius Hong & Wang, 1990 is described and illustrated based on a complete compression fossil of the fly. Currently placed in Rhagionemestriidae or Xylophagidae, the present study concludes that the morphology of the new find indicates that Sinonemestrius is a heterostomid genus within Tabanomorpha. The placement of Ahirmoneura neimengguensis K-y Zhang et al., 2008 is reassessed. It demonstrates close similarities in body structure and wing venation to those of Sinonemestrius, and can be provisionally transferred from Nemestrinidae to Heterostomidae: Sinonemestriinae.
