TL;DR: Comparison of distribution records and major vegetation types indicate the absence of information on the hepialid fauna for much of the northeast region, and the inclusion of voucher collections of Hepialidae in future biodiversity surveys of northeastern India is to be strongly encouraged.
Abstract: Taxonomic and biological information is reviewed for the forest Hepialidae of northeastern India, a poorly known group of moths in a region known for the global significance of its biodiversity. The taxonomic and biological characteristics are described for genera known from the northeast - Endoclita , Palpifer , and Hepialiscus . A key is provided for distinguishing these genera and the genus Thitarodes known from nearby Bhutan, China, and Nepal, which is almost certainly present within the borders of India. Taxonomic characteristics are described for 12 species from the northeast along with illustrations of the species and maps of their known distributions. Information on species distributions is extremely fragmentary and it is considered very likely that most species have more extensive distributions than currently documented. The northeastern Indian region represents a center of hepialid diversity comprising three principal distribution patterns: (i) local endemics, (ii) Himalayan, and (iii) northeastern. Comparison of distribution records and major vegetation types indicate the absence of information on the hepialid fauna for much of the northeast region. The principal challenge for future documentation and assessment of the hepialid fauna for this region, as with any other part of India, is the lack of modern descriptions of type specimens. The inclusion of voucher collections of Hepialidae in future biodiversity surveys of northeastern India is to be strongly encouraged, particularly in the context of current and future environmental impacts affecting the sustainability of forest environments in the region.
TL;DR: Three new species of Hepialiscus Hampson are named and described and their morphology is described and figured, and compared with H. nepalensis (Walker) and Oxycanus goldfinchi Tindale.
Abstract: Three new species of Hepialiscus Hampson are named and described; Hepialiscus robinsoni, H. taiwanus, and H. monticola. Their morphology is described and figured, and compared with H. nepalensis (Walker) and Oxycanus goldfinchi Tindale. The geographical distribution of the known oriental species of Hepialiscus and of its allied genera is shown.
TL;DR: The Leiden Museum of Natural History has received a gigantic Hepialid, sent over by Mr. O. Stolz from Soerian, unknown that in Sumatra such insects are living, and the number of the Hepialidae begins to rise, till the Australian regions, where the maximum of species is to be found.
Abstract: The Leiden Museum of Natural History has received a gigantic Hepialid, sent over by Mr. P. O. Stolz from Soerian (distr. Alahan Pandjang, W. Sum.). As far as I can find in literature, it was till now unknown that in Sumatra such insects are living. In the East-Indian Archipelago Hepialidae are known from Borneo, Java and Amboina, from the Aroe islands and from New-Guinea. Java is inhabited by representatives of three genera: Palpifer Hamps., Hepialiscus Hamps. and Phassus Moore. Their species are not numerous. Mr. P. C. T. Snellen recorded in the „Tijdschrift voor Entomologie", vol. XLIII, pp. 29—33 the following species: Palpifer sordida Snell., Hepialiscus marcidus Butl., Phassus damor Moore and Phassus signifer Walk. From Borneo is only known Phassus signifer Walk.; from Amboina are recorded Hepialus rosatus Pag. and Hepialus tegulatus Pag. On the Aroe islands Casana trichiloides Walk, has been captured. No sooner had we come into New-Guinea, than the number of the Hepialidae begins to rise, till we have reached the Australian regions, where the maximum of species is to be found. These communications are drawn from the „Lepidopterorum Catalogus" by Aurivillius and Wagner, part 4, 1911.
Returning to the Hepialidae from Sumatra I must mention moreover two specimens of Phassus damor Moore in the collection of Messrs. Piepers and Snellen. For the determination of these species I have used: List Spec. Lep. Ins. Coll. Brit. Mus. by F. Walker, 1856; Cat. Lep.
Ins. Mus. E. I. C. by Th. Horsfield and Moore, 1858—1859; Faun. Brit.
Ind. by G. F. Hampson, 1892, and the above cited memoir by Mr.
Snellen. Judging from these works the specimen collected by Mr. Stolz
