This study describes two new species of the lace bug genus Omoplax Horváth, 1912 (Hemiptera: Heteroptera: Tingidae) from Mukojima Island, the Ogasawara Islands, Japan, under the names O. karubei sp. nov. and O. mukojimensis sp. nov. These new species differ from the other species of Omoplax mainly in the shape of the pronotum and hemelytron. In all, five species belonging to two endemic genera are recognized from the Ogasawara Islands: Acanthomoplax tomokunii Souma & Kamitani, 2021, Omoplax desecta (Horváth, 1912), O. karubei sp. nov., O. majorcarinae Guilbert, 2001, and O. mukojimensis sp. nov. Additionally, several new records of tingid taxa endemic to these islands are provided: Acanthomoplax tomokunii Souma & Kamitani, 2021 from Ototojima Island, and Omoplax desecta (Horváth, 1912) from the Mukojima Group, and Meijima, Mukohjima and Nakoudojima islands. An updated key to the species is presented to facilitate the identification of Ogasawaran lace bugs.

The cetoniine genera Elaphinis Burmeister, 1842 and Parelaphinis Marais & Holm, 1989 are reviewed in the light of substantial new material that has become available recently. A new species, E. matatiele sp. nov., in the previously monotypic subgenus Elaphinis s. str. and closely related to E. (E.) cinereonebulosa (De Geer, 1778), is described from the southern Drakensberg area near Matatiele (Eastern Cape, South Africa). Within Parelaphinis, two new species, P. umtamvuna sp. nov. and P. drakensbergica sp. nov. are described and compared with P. moesta (Gory & Percheron, 1833) – hitherto the only member of the genus. The former is a mid- to lowland dweller, currently known only from the KwaZulu-Natal side of the Umtamvuna River valley (South Africa). The latter is a montane species apparently distributed across the eastern portion of the Drakensberg Escarpment, from the north-eastern Free State (South Africa) to eSwatini (formerly Swaziland). A review of the enigmatic species E. (Micrelaphinis) pumila Boheman, 1857, also presumably originating from the same broader region, reveals that only five specimens, three of which belong to the type series, are currently still traceable to accessible collections, while no further specimens have been found since the 19th century. It is here established that the type series collected by Wahlberg during the period 1838–1845 most likely originated from the Orange River valley, either in the Eastern Cape, Free State or Lesotho. As this area has been extensively transformed by agricultural and mining activities, as well as human settlements, it is hypothesized that the species may already be extinct. All the species analysed in detail are illustrated, and dichotomic keys to all species of both genera are provided to facilitate their identification.

A correction is provided regarding the identity of a fossil larva recently reported to represent the first Cretaceous record of its kind for the tenebrionoid family Mordellidae (Coleoptera, tumbling flower beetles). A review of the description of the specimen, however, reveals it to be a larval symphytan (order Hymenoptera), and likely of the family Pamphiliidae. The evidence for the revised identification is summarized.

Psilorrhynchus bifasciatus (Blanchard, 1844) is broadly distributed through South America, but its biology, behaviour and life cycle are unknown. The most characteristic feature of the adults is slender rostrum, presumably associated to a specialised feeding habit. However, new observations of P. bifasciatus feeding on nectar in inflorescences of Matayba guianensis Aubl. (Sapindaceae) do not support such a hypothesis. Here, we describe and illustrate their early larval instars in details and compare them with the other Chauliognathini. The larvae are remarkably characterised especially by a long and thick pubescence, conspicuous roughness on the head and thoracic terga, and head with sharp lateral projections. These features are unique amongst the known Cantharidae larvae and do not confirm a previous hypothesis of close affinity between Psilorrhynchus Gemminger & Harold, 1869 and bromeliad-inhabiting Chauliognathini species.

A new diving beetle, Copelatus mkambati sp. nov., is described from the Mkambati Nature Reserve in the Eastern Cape Province, South Africa. The new species is compared with other Afrotropical taxa with two elytral striae and no submarginal stria (the macellus species group of Copelatus Erichson, 1832). A combination of small eyes, rather weak pigmentation, flattened, subparallel habitus, relatively large head and collecting circumstances all suggest that the new species may be semisubterranean in lifestyle.
