Saridoscelis Meyrick, 1894 belongs to Yponomeutidae, with 9 described species. A new species, Saridoscelis diffusolinearum Lu & Hsu, sp. nov., is described from Taiwan, with diagnostic characters provided for both sexes herein. We also proposed that S. diffusolinearum sp. nov. is close related to S. kodamai Moriuti, 1961. The new species feeds on a subalpine bush Gaultheria cumingiana Vidal (Ericaceae) further indicating that the host plant of the subfamily Saridoscelinae may restricted to Ericaceae.

Introduction of organisms to new range may impose detrimental effects on local organisms, especially when closely related species are involved. Species delimitation employing an integrative taxonomy approach may provide a quick assessment for the species status between taxa of interest, and to infer ecological competition and/or introgression that may be associated with the introduction. A nymphalid butterfly, Symbrenthia lilaea lunica, was recently introduced to Taiwan, where a closely related local taxon, S. l. formosanus, can be found. We employed multiple species delimitation methods to study the species status between the two taxa, and the results revealed that they can be recognized as two distinct species, revised to S. l. lilaea (syn. nov.) and S. formosanus (stat. rev.) respectively. We further performed a niche modeling approach to investigate the ecological interaction between the two species. The taxonomic status of the two taxa, now elevated to species, has been revised and conservation facing rapid expansion of the introduced species discussed. [ABSTRACT FROM AUTHOR]

Lycaena nisa Wallace, 1866 was described from Formosa (Taiwan) and is here recognized as a senior subjective synonym of Lycaena alsulus Herrich-Schäffer, 1869. It is resurrected to serve as the valid name, Famegana nisa (Wallace, 1866), comb nov. of the species commonly known as Famegana alsulus. The name Zizera taiwana Sonan, 1938 (syn. nov.), also described from Formosa, is recognized as a junior subjective synonym of L. nisa. Another name, Zizeeria alsulus eggletoni Corbet, 1941 (syn. nov.), described from Hong Kong is also considered a junior subjective synonym of L. nisa. Moreover, all former synonyms of alsulus automatically become new junior synonyms for nisa. This species occurs in the Oriental and Australian regions and western Pacific. [ABSTRACT FROM AUTHOR]

Two new species of Stathmopodidae are described from Taiwan: Cuprina atayalica Shen & Hsu, sp. nov., reared from larvae on Microsorum brachylepis, and C. insolita Hsu & Shen, sp. nov., reared from larvae on Tectaria subtriphylla and T. harlandii. Diagnostic characters for both species are provided. Larval host plants and the biology of the immature stages of both new species are documented. [ABSTRACT FROM AUTHOR]

Two new species of the tribe Synanthedonini are described from Taiwan: Synanthedon auritinctaoidis sp. nov. and Paranthrenella helvola sp. nov. Diagnostic characters for the two species are presented using body color, wing pattern, and genitalia. New records of the relationships between host plants and the immatures are also provided. S. auritinctaoidis feeds in the trunk of Cinnamomum camphora (Lauraceae) and P. helvola in callus tissue of Helicia formosana (Proteaceae) or Prunus campanulata (Rosaceae). [ABSTRACT FROM AUTHOR]

The article presents a study that deals with systematic status of Agehana elwesi f. cavaleriei swallowtail butterflies. The authors used morphology or molecular characters to examine the relationship between f. cavaleriei and A. maraho, an endangered taxon endemic to Taiwan. Based on the male genitalia and a 1530 bp fragment of mitochondrial DNA including the cytochrome oxidase I barcoding region, the authors linked f. cavaleriei with A. elwesi which is widespread in the southern part of continental China.
