Rhadinopyga n. gen. is erected for Diceropyga recedens (Walker) from Salawati, D. impar (Walker) and D. acuminata Duffels, both from Waigeo, and Rhadinopyga epiplatys n. sp. from the “Vogelkop” area ( = Tjendrawasih) of New Guinea and the islands of Misoöl and Batjan. Phylogenetic analysis suggests a sister-group relationship of Rhadinopyga n. gen. and Diceropyga Stål. The endemism of Rhadinopyga in the “Vogelkop” area is discussed in connection with the geological history of the area and the historical biogeography of the subtribe Cosmopsaltriaria.

Inti gen. nov. (Hymenoptera: Eulophidae: Entedoninae), is described from Costa Rica and the Dominican Republic, and includes one new species, I. levis sp. nov. The new genus is characterized by four autapomorphies, and the possession of an additional 14 synapomorphies. Inti is compared to the Australian genus Horismenoides Girault with which it shares the most apomorphies, indicating a possible sister-group relationship. The relationship of Inti to the tribe Euderomphalini and to other groups in the subfamily is discussed briefly.

Phylogenetic analysis of DNA sequence data from the nuclear CAD (rudimentary) and mitochondrial NDI, COI, and 16S gene regions (2817 bp total) recovered exemplars of the genus Dohrniphora as a monophyletic lineage. The data also supported the sister-group relationship of Dohrniphora + Diplonevra and were used to associate a morphologically dissimilar male and female of the species D. ecitophila. Further, we discuss the implications of this designation and provide support for the synonymy of D. ecitophila and D. geminata as proposed by Borgmeier (1968).

A phylogenetic analysis of the Mycetophilinae is presented and discussed. The analysis is based on morphological characters for 27 genera. Fourteen equally parsimonious trees were found. The monophyly of the Mycetophilinae and the two tribes, Exechiini and Mycetophilini, is well supported. Within the Exechiini, good support for the sister-group relationship of Exechia and Exechiopsis was found, as was support for the inclusion of Cordyla in the tribe. The analysis provides good resolution within the Mycetophilini, with Trichonta as the sister group of the remaining taxa.

Although bradoriids locally are common components of the Cambrian biota, they have been reported previously from Antarctica only from Tertiary glacial deposits. Here, we describe the bradoriid,Bicarinella evansinew genus and species, collected in situ from the upper Lower Cambrian (Botomian) of the Pensacola Mountains in East Antarctica.Bicarinella evansin. gen and sp. is characterized by a subtriangular carapace with a well-defined marginal rim, subequal anterior and posterior lobes that are elongated into sharp ridges extending one-third the length of the carapace, and a broad dorsal node placed between the anterior and posterior lobes. The surface of the carapace exhibits three kinds of ornamentation: fine pitting, pustules, and reticulae. Several smaller carapaces with reduced ornamentation collected from the same bed are interpreted as instars of this species.Bicarinellan. gen. is assigned to the family Hipponicharionidae and appears to be closely related toAlbrunnicolaMartinsson, 1979, orHipponicharionMatthew, 1886. Although strong archaeocyath faunal similarities demonstrate a close biogeographic relationship between Australia and Antarctica in the Early Cambrian, the possible sister group relationship ofBicarinellan. gen. toHipponicharion, which is otherwise unknown from Gondwana, may suggest a separate biogeographic pathway to East Antarctica that did not involve Australia.

The genus Thoris Pascoe is revised. Two species are described as new: T. octoguttata from Australia and T. brandti from New Guinea. Diagnoses of all other species are given and their terminaha described. T. moerens Blackburn is transferred to Allotisis Pascoe. A key to the eight species is provided. Phylogenetic analysis suggests that this genus be divided into three species-groups: the gilesi-group, the quinqueguttata-group and the septemguttata-group. Biogeographic implications of the genus are discussed on the basis of the genus' proposed phylogeny, present distribution and geological history of New Guinea and Australia.

Abstract. Baenidae is a clade of paracryptodiran turtles known from the late Early Cretaceous to Eocene of North America. The proposed sister-group relationship of Baenidae to Pleurosternidae, a group of turtles known from sediments dated as early as the Late Jurassic, suggests a ghost lineage that crosses the early Early Cretaceous. We here document a new species of paracryptodiran turtle, Lakotemys australodakotensis gen. and sp. nov., from the Early Cretaceous (Berriasian to Valanginian) Lakota Formation of South Dakota based on a poorly preserved skull and two partial shells. Lakotemys australodakotensis is most readily distinguished from all other named Late Jurassic to Early Cretaceous paracryptodires by having a broad, baenid-like skull with expanded triturating surfaces and a finely textured shell with a large suprapygal I that laterally contacts peripheral X and XI and an irregularly shaped vertebral V that does not lap onto neural VIII and that forms two anterolateral processes that partially separate the vertebral IV from contacting pleural IV. A phylogenetic analysis suggests that Lakotemys australodakotensis is a baenid, thereby partially closing the previously noted gap in the fossil record.

The powder post beetles (Coleoptera: Bostrichidae) (except Lyctinae) of Yunnan Province in Southwest China are reviewed for the first time. Keys to twenty-six genera and fifty-two species from the Yunnan region are provided. One new genus and seven new species are described: Dinoderus (Dinoderastes) hongheensis sp. nov., Dinoderus (Dinoderastes) nanxiheensis sp. nov., Gracilenta yingjiangensis gen. nov., sp. nov., Calonistes vittatus sp. nov., Calophagus colombiana sp. nov., Xylodrypta guochuanii sp. nov. and Xylodrypta zhenghei sp. nov.. Fourteen species are recorded in China for the first time. The bostrichid fauna of Yunnan is compared with those of the neighbouring bio-geographically related Southeast Asian and Himalayan regions. The fauna has a close affinity with that of tropical Southeast Asia and a much weaker relationship with the Palearctic region. The differences with the Himalayas may reflect the separate evolutionary and complex geological history of the two areas.

Complete Mitochondrial Genomes

Insects of the order Phasmatodea are mainly distributed in the tropics and subtropics and are best known for their remarkable camouflage as plants. In this study, we sequenced three complete mitochondrial genomes from three different families: Orestes guangxiensis, Peruphasma schultei, and Phryganistria guangxiensis. The lengths of the three mitochondrial genomes were 15,896 bp, 16,869 bp, and 17,005 bp, respectively, and the gene composition and structure of the three stick insects were identical to those of the most recent common ancestor of insects. The phylogenetic relationships among stick insects have been chaotic for a long time. In order to discuss the intra- and inter-ordinal relationship of Phasmatodea, we used the 13 protein-coding genes (PCGs) of 85 species for maximum likelihood (ML) and Bayesian inference (BI) analyses. Results showed that the internal topological structure of Phasmatodea had a few differences in both ML and BI trees and long-branch attraction (LBA) appeared between Embioptera and Zoraptera, which led to a non-monophyletic Phasmatodea. Consequently, after removal of the Embioptera and Zoraptera species, we re-performed ML and BI analyses with the remaining 81 species, which showed identical topology except for the position of Tectarchus ovobessus (Phasmatodea). We recovered the monophyly of Phasmatodea and the sister-group relationship between Phasmatodea and Mantophasmatodea. Our analyses also recovered the monophyly of Heteropterygidae and the paraphyly of Diapheromeridae, Phasmatidae, Lonchodidae, Lonchodinae, and Clitumninae. In this study, Peruphasma schultei (Pseudophasmatidae), Phraortes sp. YW-2014 (Lonchodidae), and species of Diapheromeridae clustered into the clade of Phasmatidae. Within Heteropterygidae, O. guangxiensis was the sister clade to O. mouhotii belonging to Dataminae, and the relationship of (Heteropteryginae + (Dataminae + Obriminae)) was recovered.

The phylogenetic position of the tuatara, Sphenodon (Sphenodontida, Amniota), as indicated by cladistic analysis of the ultrastructure of spermatozoa

Sphenodon has traditionally been regarded as a little changed survivor of the Permo-Triassic thecodont or eosuchian ‘stem reptiles’ but has alternatively been placed in the Lepidosauria as the plesiomorphic or even apomorphic sister-taxon of the squamates. A cladistic analysis of 16 characters from spermatozoal ultrastructure of Sphenodon and other amniotes unequivocally confirms its exceedingly primitive status. The analysis suggests that monotremes are the sister-group of birds; squamates form the sister-group of a bird + monotreme clade while the three sister-groups successively below the bird + monotreme + squa- mate assemblage are the caiman, the tuatara and the outgroup (turtles). The monotreme + bird couplet, supports the concept of the Haemothermia, but can only be regarded heuristically. The usual concept of mammals as a synapsid-derived outgroup of all other extant amniotes is not substantiated spermatologically. All cladistic analyses made, and a separate consideration of apomorphies, indicate that Sphenodon is spermatologically the most primitive amniote, excepting the Chelonia. It is advanced (apomorphic) for the amniotes in only two of the 16 spermatozoal characters considered. A close, sister-group relationship of Sphenodon with squamates is not endorsed.
