The genus Paratrichapus Scott, 1926 currently comprises four species, one described from the Seychelles Islands in the Indian Ocean, one from Indonesia and two from New Zealand. Here, the first Australian species of Paratrichapus are described, as follows: P. australis sp. n., P. burwelli sp. n., P. christmasensis sp. n., P. metallonotum sp. n. and P. peckorum sp. n. Data on their geographic distribution and host fungi are provided, as well as an identification key.

The Carboniferous insect taxon †Stephanastus polinae was assigned to a monotypic new order †Skleroptera, which was postulated as the sister group of the clade Strepsiptera + Coleoptera (= Coleopterida). The placement of †Stephanastus in Holometabola and the proposed relationship with Coleopterida are very likely unjustified. Suggested shared derived features of Skleroptera + Coleopterida are vague, insufficiently documented (characters of proximal leg segments) or likely based on misinterpretation (wing veins). Based on the wing venation we suggest a position in the extinct hemimetabolous order †Protelytroptera.

The New World family Heterothripidae (~90 spp., four genera) comprises flower-feeding and ectoparasitic thrips. The monophyly of the group has remained untested and species-level relationships were unknown. Morphological (123 characters) and molecular (28S rDNA D2 and D3-D5, H3, and partial COI) data were compiled to reconstruct phylogenetic relationships of this group. The ingroup was represented by 65 species of the four recognized Heterothripidae genera (Aulacothrips Hood, Heterothrips Hood, Lenkothrips De Santis & Sureda, and Scutothrips Stannard). The monophyly of Heterothripidae was recovered in the total evidence and molecular data only analyses with the ectoparasitic Aulacothrips placed as the sister group of the remaining Heterothripidae. The large genus Heterothrips (>80% of the species-level diversity), which was thoroughly sampled in our analyses (56 species), was recovered as paraphyletic with respect to Scutothrips and Lenkothrips. We conclude that additional morphological and molecular data would be desirable before revising the classification of Heterothripidae

Stephanidae (Hymenoptera, Stephanoidea) are solitary idiobiont ectoparasitoids of wood boring insect larvae. Here we present two genera, i.e., Afromegischus van Achterberg, 2002 and Foenatopus Smith, 1861, and five species, i.e., A. gigas (Schletterer, 1889), F. bisignatus Aguiar & Jennings, 2010, F. crispus Aguiar, 2010, F. nimaarkanii Ghafouri Moghaddam & Rakhshani sp. n. and F. prousti Aguiar & Turrisi, 2010 from Iran. Specimens were collected in southeastern Iran (Kerman and Sistan-o Baluchestan) from unknown hosts. Their morphological features and distribution are discussed in relation to the overall knowledge in the target and adjacent regions. Foenatopus nimaarkanii sp. n. is incorporated to the key for the identification of Foenatopus species with double spots on metasomal tergites.

The species Calyptra minuticornis is divided into two subspecies: C. minuticornis novaepommeraniae (Strand) and C. minuticornis minuticornis (Guenée) based on minor morphological differences, geographic distribution, and differential feeding behaviors in the adults. In this study, museum specimens were examined, including the holotypes of C. novaepommeraniae and C. minuticornis. A comprehensive distribution map was generated for C. minuticornis. A permutational multivariate analysis of variance provided some statistical evidence for minor differences between the male genitalic morphology. Additionally, the maximum parsimony analysis of the C. minuticornis subspecies complex resulted in a polytomy and did not represent natural groupings. From these results, it can be concluded that C. minuticornis novaepommeraniae and C. minuticornis minuticornis should be synonymized. A redescription of the species and a revised checklist for the genus is also provided. This includes synonymization of Wolframmeyia Behounek, Hacker & Speidel with Calyptra and evidence that Percalpe Berio is an unavailable name.

The taxonomic history, composition, morphology, distribution, and bionomics of the genus Dila Fischer von Waldheim, 1844 are discussed. The following new generic synonymy is established: Dila Fischer von Waldheim, 1844 = Caenoblaps König, 1906, syn.n. As a result, four species are transferred from Caenoblaps to the genus Dila: Dila difformis (König, 1906), comb.n., Dila nitida (Schuster, 1920), comb.n., Dila baeckmanni (Schuster, 1928), comb.n., Dila kulzeri (Schuster, 1928), comb.n. A new synonymy is established: Blaps kulzeri Pierre, 1964 = Caenoblaps kulzeriana Pierre, 1964, syn.n. A taxonomic review of the eight known Caucasian, Turkish and Iranian species is given. Lectotypes of Caenoblaps nitida and Caenoblaps difformis are designated. Three new species are described: Dila hakkarica sp.n. and Dila svetlanae sp.n. from the Hakkary Province of Turkey and Dila crenatopunctata sp.n. from West Azerbaijan Province of Iran. The position of the genus Dila within the tribe Blaptini and subtribal classification are discussed.

The subgenus Canthon (Pseudepilissus) Martínez, 1954 is revised. Four valid species are redescribed: Canthon (Pseudepilissus) muticus Harold, 1867; C. (P.) lunatus Schmidt, 1922; C. (P.) planus Lucas, 1857 and C. (P.) reichei Felsche, 1910. Three species assigned to other groups are transferred in the subgenus: C. (P.) quadratus Blanchard, 1843 [previously Canthonincertae sedis”]; C. (P.) edentulus Harold, 1868 [previously Canthonincertae sedis”] and C. (P.) seminulus Harold, 1867 comb. nov. [previously Vulcanocanthon]. The genus Vulcanocanthon Pereira & Martínez, 1960 syn. nov. is synonymized with Canthon (Pseudepilissus). Three subspecies are raised to species level: C. (P.) tibialis Schmidt, 1922 stat. nov. [previously C. (P.) lunatus tibialis]; C. (P.) granuliceps Felsche, 1910 stat. nov. [previously C. edentulus granuliceps] and C. (P.) hendrichsi Halffter & Martínez, 1968 stat. nov. [previously C. (P.) muticus hendrichsi]. C. (P.) honsi Balthasar, 1939 syn. nov. is synonymized with C. (P.) reichei Felsche, 1910. Four new species are described: Canthon (P.) arriagadai sp. nov., Canthon (P.) bonaerensis sp. nov., Canthon (P.) vidaurrei sp. nov. and Canthon (P.) ziggy sp. nov., bringing the number of species in the subgenus to 14.

A systematic review of the tribe Hyaliodini from Australia and New Caledonia is given. Four new genera and 13 new species of Hyaliodini described: Bolbomiris gen. n. (B. cola sp. n., B. samuelsoni sp. n.), Epelisentis gen. n. (E. celiae sp. n., E. gressitti sp. n.), Plikomiris gen. n. (P. freycinetiaphilus sp. n., P. monteithi sp. n.) and Torunotum gen. n. (T. badius sp. n., T. hystrix sp. n., T. oviformis sp. n., T. pindaii sp. n. and T. psydrax sp. n.), as well as Femurocoris madeleinensis sp. n., Montagneria yahouensis sp. n. Femurocoris Carvalho and Montagneria Akingbohungbe and their type species are redescribed, as is M. cuneatus (Distant). Stethoconus praefectus (Distant) is reported from Australia for the first time. A dichotomous key, illustrations of male genitalia, scanning electron micrographs and habitus photographs are provided. A phylogenetic analysis of a morphological dataset was undertaken resulting in a monophyletic Hyaliodini, and the New Caledonian hyaliodines form a subclade. A discussion of the infra-subfamilial classification of the Deraeocorinae is given.

Platygerris White comprises true bugs that inhabit the surface of water in moderate to fast-flowing freshwater habitats. This genus differs from Cylindrostethus Mayr and Potamobates Champion (Gerridae: Cylindrostethinae) by having a short and flattened body; the mandibular and maxillary plates fused; and the omphalium, lateral groove, and lateral evaporatorium of the scent apparatus inconspicuous. In this paper, we redescribe Platygerris, describe two new species from Colombia, and redescribe P. asymmetricus Hungerford, P. caeruleus Champion and P. depressus White. In addition, we present an updated identification key to the species of the genus. For the first time, the cuticular structure is described for the genus based on electron microscopy.
