New fossils from China elucidating the phylogeny of Praesiricidae (Insecta: Hymenoptera)

A new subfamily of Praesiricidae (Pamphilioidea), Decorisiricinae subfam.n., is erected based on three new genera: Decorisiricius gen.n., Limbisiricius gen.n. and Brevisiricius gen.n. Two new species – Decorisiricius patulus gen. et sp.n. and D. longus sp.n. – from the Lower Cretaceous Yixian Formation and three species –Limbisiricius aequalis gen. et sp.n., Limbisiricius complanatus sp.n. and Brevisiricius partialis gen. et sp.n. – from the Middle Jurassic Jiulongshan Formation, are described. Based on these well‐preserved new fossil specimens and previously published data, the nonmonophyly of Praesiricidae is confirmed and the phylogenetic relationships of species of Praesiricidae are analysed for the first time. Two main clades within Praesiricidae are recognized from the cladistic analysis: Decorisiricinae subfam.n. forms a monophyletic lineage, with the remaining members of Praesiricidae plus Megalodontes (Megalodontesidae) forming its sister group. The two subfamilies Archoxyelydinae and Praesiricinae are discarded with no strong supported synapomorphic characters based on phylogenetic research. A key to all genera of Praesiricidae is provided.

A contribution to the knowledge of Agathidinae (Hymenoptera: Braconidae) from Iran with description of a new species

The subfamily Agathidinae was studied in parts of northern Iran. Six species were collected and identified. Among them, Cremnops desertor (L., 1758) is recorded for the first time from Iran. Lytopylus persicus Farahani & Talebi sp. n. is described and illustrated. A key to the West Palaearctic species of the genus Lytopylus Förster and an updated checklist of Iranian Agathidinae are provided.

Weighted compromise trees: a method to summarize competing phylogenetic hypotheses

A new consensus method for summarizing competing phylogenetic hypotheses, weighted compromise, is described. The method corrects for a bias inherent in majority‐rule consensus/compromise trees when the source trees exhibit non‐independence due to ambiguity in terminal clades. Suggestions are given for its employment in parsimony analyses and tree resampling strategies such as bootstrapping and jackknifing. An R function is described that can be used with the programming language R to produce the consensus.

Three new species of Sesioctonus Viereck (Hymenoptera, Braconidae, Agathidinae) from Peru

Abstract Three new species of Sesioctonus (Braconidae: Agathidinae) are described and illustrated, i.e., Sesioctonus huggerti, Sesioctonus wayquecha, and Sesioctonus bina. Two new Peruvian species records for Sesioctonus are reported: Sesioctonus longinoi and Sesioctonus diazi. A revised key to all known species of Sesioctonus is presented.

A New Species of Leluthia (Braconidae: Doryctinae) from Mexico

Abstract Leluthia danielensis n. sp. (Hymenoptera: Braconidae), reared from Scolytopsis puncticollis Blandford (Coleoptera: Curculionidae), is described from Mexico. Illustrations of lateral and dorsal habitus and wings are provided.

Two species and a genus new for Thailand, with description of a new species of Neurolarthra Fischer (Hymenoptera: Braconidae: Alysiinae)

The taxonomic history of Hellwigiella Szépligeti is presented with comments. Ophion similis (Szépligeti, 1905) is diagnosed and illustrated, with the first record for Morocco. Hellwigiella is redescribed and illustrated, with comments on its differentiation from O. similis. A key to the two valid species, H. dichromoptera and H. nigripennis stat. rev., is provided.

Separatatus Chen & Wu (Hymenoptera: Braconidae: Alysiinae) newly recorded from Thailand, with description of one new species and one new combination

Separatatus Chen Wu, 1994, is reported for the first time from Thailand and one new species is described and illustrated: Separatatus xuexincheni n. sp. In addition, one species is newly recorded from Thailand (S. parallelus Zhu et al., 2017) and we transfer one species from Phasmidiasta to Separatatus: S. malaysiae (Fischer, 2006) n. comb. A key to species of the genus Separatatus is presented.

Addendum to “Phylogeny of the Agathidinae (Hymenoptera: Braconidae) with a Revised Tribal Classification and the Description of a New Genus” (Sharkey and Chapman, 2017, Proc Entomol Soc Wash 119 (Special Issue): 823-842)

This addendum serves to correct an accidental omission from Sharkey and Chapman (2017). In that paper, we present a phylogeny of the Agathidinae (Fig. 1) that has the outgroup (nonagathidine) taxa removed and all of the ingroup genera represented by multiple species collapsed into single terminals representing each genus. The intent was to have an additional file available that contained three unpruned trees from three phylogenetic analyses of the data set: (Suppl. Fig. 1) the tree of highest log likelihood from a maximum likelihood (ML) analysis, (Suppl. Fig. 2) the ML bootstrap tree, and (Suppl. Fig. 3) the majority-rule consensus tree from a Bayesian analysis. These trees were in a single pdf referred to in the paper as Appendix II. This file was accidentally omitted from the published paper and we are making that file available here.

Revision of the subfamily Cardiochilinae Ashmead, 1900 (Hymenoptera: Braconidae) in Egypt, with new records and a new species

ABSTRACT In the present study, the subfamily Cardiochilinae (Hymenoptera: Braconidae) is revised. This study is based on specimens deposited in Egyptian repositories. Many of them were collected during Priesner’s trips to Gebel Elba (extreme south-west of Egypt). The subfamily Cardiochilinae is represented in Egypt by 11 species in three genera, Bohayella Belokobylskij, 1987 (one species), Cardiochiles Nees, 1819 (three species) and Schoenlandella Cameron, 1905 (seven species). The cardiochiline species C. pseudofallax Telenga, 1955 and S. deserta (Telenga, 1955) are recorded here as new records in the fauna of Egypt. The females of previously known male C. weidholzi Fischer, 1958, S. acrenulata (Fischer, 1958) and S. obscuriceps (Fischer, 1958) as well as the male of the previously known female S. glabra (Fischer, 1958) are described. Schoenlandella pseudoglabra sp. nov. is also described and illustrated. www.zoobank.org/urn:lsid:zoobank.org:pub:C134A1AA-81F6-4661-9C7B-12A7CAE08F67

A dichotomous key and a link to an electronic, interactive key are included. All specimens were reared from Lepidoptera larvae collected in Area de Conservación Guanacaste (ACG) and all are associated with ecological information including host caterpillar, collection date, eclosion date, caterpillar food plant, and locality. Neighbor-joining and maximum likelihood analyses of the barcode region of the mitochondrial cytochrome c oxidase subunit I gene (COI DNA barcode) were conducted to aid in species delimitation.
