Taxonomic study of Uncobotyodes Kirti & Rose, 1990 (Lepidoptera, Crambidae), with the description of a new species from China.

The monotypic genus Uncobotyodes Kirti & Rose and its type species U. patulalis (Walker) are redescribed. The female genitalia of U. patulalis are described for the first time. An additional species, Uncobotyodes latizona sp. nov., is described as new to science. The two species of the genus are compared. Images of adults and their genitalia are provided.

Revision of the genus Charitoprepes Warren (Lepidoptera, Crambidae), with the description of a new species from China.

The genus Charitoprepes is revised based on morphological characteristics, and Charitoprepesaciculatasp. nov. is described as new from China. Additionally, the female genitalia of C.lubricosa are described for the first time based on new material. The differences among species of this genus are diagnosed, along with images of adults and their genitalia.

Five new species of Bradina Lederer (Lepidoptera, Crambidae) from China, with remarks on the morphology of the genus.

Bradina is a species-rich genus that differs from most other Spilomelinae genera because of its distinctive wing venation. Most species of this genus are very similar in appearance. In this study, we have studied morphological characteristics of the genus and eight closely related species from China. Among them, B.falciculata Guo & Du, sp. nov., B.fusoidea Guo & Du, sp. nov., B.spirella Guo & Du, sp. nov., B.ternifolia Guo & Du, sp. nov. and B.torsiva Guo & Du, sp. nov. are described as new to science. Bradinamegesalis (Walker, 1859), B.translinealis Hampson, 1896 and B.subpurpurescens (Warren, 1896) are redescribed based on their holotypes and additional material, and the latter two are newly recorded from China and their genitalia are described for the first time. The images of the habitus and genitalia of these eight species are provided, with a key to their identification.

Revision of Nagiella Munroe (Lepidoptera, Crambidae), with the description of a new species from China.

The genus Nagiella was studied using morphological and DNA barcode data. Nagiella bispina sp. nov. is described as a new species, and N. hortulatoides Munroe is recorded in China for the first time. The diagnosis of this genus is revised, and the genitalia description of N. quadrimaculalis (Kollar and Redtenbacher) and N. inferior (Hampson) are given in English for the first time. Nosophora incomitata (Swinhoe) stat. rev. is removed from the synonym of N. quadrimaculalis. Photographs of the habitus and genitalia as well as COI DNA Barcode data of these four species are provided.

Three new species of Herpetogramma Lederer (Lepidoptera, Crambidae) from China.

Five species of the genus Herpetogramma in China are studied with morphological and DNA barcode data. Herpetogrammabiconvexa Wan, Lu & Du, sp. nov., H.longispina Wan, Lu & Du, sp. nov., and H.brachyacantha Wan, Lu & Du, sp. nov. are described as new. Herpetogrammarudis (Warren) and H.magna (Butler) are newly diagnosed. Photographs of the habitus and genitalia of these five species are provided.

A new species of Patania from the Hainan Island, China (Lepidoptera, Crambidae).

Patania clava sp. n. is described from the Diaoluo Mountain of Hainan Island, China. The new species is distinguished from its most similar congener, Patania iopasalis (Walker, 1859), by the following features: wingspan 33.0-35.0 mm (vs. 21.0-30.0 mm), ventral cilia of the male antenna as long as the diameter of flagellomere (vs. 1/4), the thick finger-like gnathos (vs. the short broad sheet-like), a long thick needle-like cornutus stretching out from (vs. embedded in) a cluster of spicular cornuti near apex. Images of adult and genitalia of the new species are provided.
