Bothriomirini is a small tropical mirid tribe that has not been comprehensively revised nor has monophyly of the tribe and included genera been tested. This paper presents a systematic review of Bothrioimrini. Bothriomirella ater gen. nov. sp. nov., Bothriomiris lorenzatoae sp. nov., Dashymenia javanensis sp. nov. , Dashymenia jaydeni sp. nov. are described as new to science. A phylogenetic analysis of Bothriomirini based on morphological data is performed. The diagnoses of the tribe and most of its genera are discussed. Bakeriola crassicornis Poppius, Bothriomiris lugubris Poppius, Bothriomiris ornatus Bergroth, Dashymeniella tibialis Poppius and Leprocapsus scutellaris Poppius are redescribed. Female genitalia of Bothrimirini are discussed for the first time. This study supports the monophyly of the tribe and most genera and documents remarkable heterogeneity of the female genitalia. New locality data and a discussion of the distribution of Bothriomirini in relation to major biomes and climatic zones are provided.

The seed beetle genus Ctenocolum Kingsolver & Whitehead is peculiar because its preferred host Lonchocharpus Kunth (Fabaceae) is not preyed upon by other bruchine species. This study investigates the phylogenetic relationships and evolution of this genus and of its species groups, while providing the description of three new species and of the male of C. biolleyi Kingsolver & Whitehead. To infer phylogenetic relationships, a character matrix of 40 morphological characters was assembled and analysed using both parsimony and Bayesian inference. Ancestral state estimations of host plant use and biogeography analyses were also performed. A total of 22 species were examined: 16 Ctenocolum species (including the three new ones) and six outgroup bruchine species (from genera Caryedes Hummel, Meibomeus Bridwell, Pygiopachymerus Pic and Pachymerus Thunberg). All resulting trees support the monophyly of the genus Ctenocolum. Three synapomorphies characterize the genus: (i) head with frontal carina enlarged at base, (ii) male pygidium truncated apically, and (iii) lateral lobes of tegmen with dorsal process. The two known species groups are also recovered monophyletic in the parsimony analyses. The following three species are described: Ctenocolum inmaculatus Manfio & Ribeiro-Costa sp. nov. (Type locality: Venezuela, Guarico), which belongs to the group tuberculatum; Ctenocolum nigronotus Manfio & Ribeiro-Costa sp. nov. (Type locality: Porto Rico, Mayaguez) and C. pallidus Manfio & Ribeiro-Costa sp. nov. (Type locality: Republic of Guyana), which belong to the group podagricus. Finally, we present colored illustrations of dorsal patterns and male genitalia for these three new species and C. biolleyi in addition to an updated key for the genus Ctenocolum.

We revise the Oriental species of Bruchomyiinae based on type and additional material, with first descriptions of the genus Alexanderia Wagner & Kvifte, gen. nov. and A. thailandensis Wagner, Rulik & Polseela, sp.nov. The genus further comprises Nemapalpus orientalis Edwards, 1928 (type species), Nemopalpus vietnamensis Quate, 1962 and Nemapalpus unicolor Edwards, 1928. Alexanderia thailandensis is described using morphology of males and females and DNA barcodes, whereas A. orientalis Edwards, 1928 comb.nov., A. unicolor Edwards 1928 comb.nov., and A. vietnamensis Quate 1962 comb. nov. are redescribed. The male and female internal genitalia in the genus are discussed in the context of sexual selection, and we suggest that the spermathecal ducts of the female and the basiphallic musculature of the male may be shaped by a male/female coevolutionary arms race.

The Japanese species of the genus Therion Curtis, 1829 (Ichneumonidae: Anomaloninae) were revised based on examination of 447 Japanese specimens. Four species are recognized based on morphology and sequence data (mtCOI). Two of them are identified as previously known species: T. circumflexum (Linnaeus, 1758) and T. giganteum (Gravenhorst, 1829). The other two species are described as new: T. carinatum Shimizu & Bennett, sp. nov. and T. nigrigasterum Shimizu, Bennett & Ito, sp. nov. In addition, T. rufomaculatum (Uchida, 1928) stat. rev. is once again synonymized with T. circumflexum. The Japanese species of Therion are easily distinguished from each other by a newly provided key. The lasiocampid moth, Dendrolimus spectabilis (Butler, 1877), is newly recorded as a host of T. giganteum.
(Myrmecozelinae, Perissomasticinae, Tineinae, Hieroxestinae, Teichobiinae and Stathmopolitinae)
Additional records are listed for species treated in volume 7, as well as two taxa which were overlooked before and nine new species are listed.

Bacotoma Moore, 1885 is reviewed including the description of a new species from Hainan Island, B. hainanensis sp. nov., based on an analysis that combined morphology and mitochondrial DNA. The following taxonomic changes are proposed: Platamonina Shaffer & Munroe, 2007, syn. nov. is synonymized with Bacotoma and ten species are included: B. ampliatalis (Lederer, 1863) comb. nov., B. binotalis (Warren, 1896) comb. nov., B. camillusalis (Walker, 1859), B. cuprealis (Moore, 1877) comb. nov., B. hainanensis sp. nov., B. illatalis (Walker, 1866), B. oggalis (Swinhoe, 1906) comb. nov., B. poecilura (Hering, 1903) comb. nov., B. ptochura (Meyrick, 1894) comb. nov., and B. violata (Fabricius, 1787). Syngamia albiceps Hampson, 1912 syn. nov. is confirmed to be a synonym of Bacotoma binotalis, and Platamonia medinalis Snellen, 1900 syn. nov. is synonymized with Bacotoma illatalis. A key to species examined is also provided based on external morphology and male genitalia.

The recent critical revision of the order Skleroptera by Beutel et al. (2018a) is considered. We show several defects in their interpretation, contradicted by the original descriptions and diagnosis (Nel et al., 2013; Kirejtshuk & Nel, 2013). The main arguments of the initial interpretation of Stephanastus polinae Kirejtshuk et Nel, 2013 (Stephanastidae) and reasons for the proposal of the order Skleroptera (Kirejtshuk & Nel, 2013) are mentioned, together with reasons to reject the proposal of Beutel et al. (2018a, b). A comparison of Skleroptera with other neopteran orders is made. Lastly the problem of the position of Umenocoleus as a member of Coleopterida versus a roachoid is discussed, the first hypothesis being supported by synapomorphies which is not the case for the second.

Bethylinae are a morphologically well-defined subfamily of Bethylidae, with remarkable characters, such as strongly convex clypeal carina and bifid and angled tarsal claws. However, there is no consensus about the phylogenetic relationships among the genera within the family, regarding mainly Eupsenella and Lytopsenella. To resolve this problem, a phylogeny of the Bethylinae is inferred based on parsimony analyses separately of 43 and 44 morphological characters for males and females, respectively. We performed combined analyses of both sexes with 49 morphological characters, including genitalia. We present a phylogenetic analysis, including a total 118 species of Bethylinae. Male and female characters were included in these analyses. We discuss wing morphology and deformability of forewings for the first time. In summary, the basal polytomy was solved for the first time. Seven of the eight genera were recovered as monophyletic groups. The unique exception is Goniozus, which was retrieved as paraphyletic in all topologies.

This paper provides a synopsis of the South American genus Diabroctis Gistel, 1858. Five species are assigned to the genus. The type species D. mimas is widely distributed and shows considerable morphological variation in male secondary sexual characters. A substantial number of morphological and geographic data are used to provide an updated diagnosis of this species, and to describe intraspecific variation. A new Brazilian species is described as Diabroctis pseudomimas sp. nov., which has been recognized among specimens confused with D. mimas (Linnaeus) in entomological collections. Additionally, the subspecies D. mimas venezuelensis is elevated to species level. Lectotypes are designated for Phanaeus mirabilis and Phanaeus mimaeformis. Diagnoses, distribution data, and an identification key are provided for all species included in the genus.
