The article updates the status of the three valid taxa of the genus Streblote Hübner, 1820 from the Malay Archipelago. The species Streblote castanea (Swinhoe, 1892) was described from an unstated location in the Philippines. Presently this species is recorded from 8 major Philippine islands: Cebu, Luzon, Mindanao, Mindoro, Negros, Palawan, Panay, and Samar. The three populations from Luzon, Mindoro, and Negros have pairwise distances ranging from 2.45 to 3.92%. Genetic distance together with geographic isolation is enough to treat the populations as separate species, but the description of new Philippine taxa is not possible until the island of the origin of S. castanea is designated. To locate the species origin and to understand relationships to other populations, the type specimen has to be barcoded. The species Streblote dorsalis (Walker, 1866) from Borneo is similar morphologically to S. castanea. It has to be sequenced as well to understand its relationship with the Philippine species and with geographically and morphologically close populations from the islands Belitung and Sulawesi. The taxon Streblote pallida (Rothschild, 1915) from Java and Bali was earlier attributed as a subspecies to S. castanea and then to S. dorsalis. It is raised here to a bona species because of its wing pattern distinct from the two species, it has an average pairwise distance of 5.15% from S. castanea. Two populations from the neighboring Sumatra, Flores and Sumba are described as new species Streblote gerry sp. n. and Streblote jacquie sp. n. Streblote pallida and S. jacquie sp. n. have a pairwise distance of up to 2.45%.

The geographical distribution of carpenter moths (Lepidoptera: Cossidae) in the Old World has been studied. Cossid faunas of different zoogeographical zones of the earth are characterized. Zoogeographical borders; centers of species diversity and generic diversity; and centers of endemism in the Palaearctic part of the Holarctic Kingdom, as well as in the Afrotropical, Indo-Malayan, and Australian zoogeographical regions, are specified. The Papuan horon is proposed to be regarded as a subregion of the Indo-Malayan region of the Paleotropical Kingdom. The Australian and New Zealand horons are also suggested to be included into the Paleotropical Kingdom as the Australian region. Finally, it is proposed that the border between the Holarctic Kingdom and the Indo-Malayan region should be rectified and that the eastern Gobi horon should be considered a separate zoogeographical superprovince.

The cossid or the Carpenter Moths (Lepidoptera, Cossidae) include about 1000 species worldwide (van Nieukerken et al., 2011), of which 750 species belong to five subfamilies that occur in the Old World (Yakovlev 2011). The Cossidae are still relatively poorly known from vast areas of the African continent, despite recent reports on the fauna of Malawi (Yakovlev & Murphey 2014), Zimbabwe (Yakovlev & Lenz 2014), and Zambia (Yakovlev 2014). The first results of an ongoing revision of the South African Cossidae have also been published (Mey 2015).

The second species of the genus Typhonoya Prozorov 2011—T. kravchenkoi Prozorov, Müller & Zolotuhin sp. n. from the Democratic Republic of the Congo is described. A previously monotypic genus becomes bitypic. One paratype specimen was collected in the buffer zone of the southern part of the Salonga National Park during a one year-long stationary expedition (June 2017–June 2018). Spread imagoes, heads, legs, venations and genitalia of both species are figured and compared. Additional notes on the genus description and previously known species are added.

Seven new species of the Afrotropic Lasiocampidae genus Rhynchobombyx are described and illustrated: Rh. gavinfilippone Prozorov, Saldaitis & Müller sp. n., Rh. avadomenicarocchio Prozorov, Saldaitis & Müller sp. n., Rh. julianjameseaton Prozorov, Saldaitis & Müller sp. n., Rh. anthonychristophereaton Prozorov, Saldaitis & Müller sp. n., Rh. nicolasroberteaton Prozorov, Saldaitis & Müller sp. n., Rh. arijakefriend Prozorov, Saldaitis & Müller sp. n., Rh. madisonellafriend Prozorov, Saldaitis & Müller sp. n. All species originate from the poorly studied Congolian lowland forests ecoregion of Congo and Democratic Republic of the Congo. Lectotype and paralectotype of Rh. nasuta Aurivillius, 1909 are designated here, the species type locality is specified.

A new genus Meyameta gen. n. is established for the South African Glocia straminea Aurivillius, 1921 which was considered within the Madagascan genus Napta Guenée, 1865 (type species Napta serratilinea Guinée, 1865) and a new species Meyameta roberti sp. n. from Namibia is described. The new genus is compared with the genera Napta and Henometa Aurivillius, 1927 (type species South African Pachymeta clarki Aurivillius, 1909).
