Taxonomy of scaly crickets (Orthoptera: Mogoplistidae: Mogoplistinae) from China: five new species groups and three new species of the genus Ornebius Guérin-Méneville, 1844.

The genus Ornebius Guérin-Méneville, 1844 was divided into five species groups based on the structure of the male genitalia. Three new species of Ornebius were described from the Chinese provinces of Hainan, Guangxi and Guangdong. Type specimens are deposited at the Museum of Flora and Fauna of Shaanxi Normal University, Xi'an, China (SNNU).

Morphological and molecular characters reveal the status of Pedesta rubella (Devyatkin, 1996) stat. n. and P. similissima (Devyatkin, 2002) syn. n. (Lepidoptera, Hesperiidae).

To clarify the relationships of Pedesta submacula (Leech, 1890), P. submacula rubella (Devyatkin, 1996) and P. similissima (Devyatkin, 2002), specimens from various localities in China and Vietnam, including the type materials of P. submacula rubella and P. similissima were examined. A neighbor-joining (NJ) tree was also reconstructed based upon partial COI sequences of 24 ingroup specimens and 4 outgroup species. The result shows that P. similissima is a synonym of P. submacula, and P. submacula rubella belongs to a separate species. The mean Kimura-2-Parameter genetic distance between P. submacula and P. rubella stat. n. is 4.4%. Wing patterns and genitalic structures of these taxa are illustrated and compared. A distribution map of both species is provided.

A new species of Tipulodina (Diptera, Tipulidae) from China, with description of the female internal reproductive system.

A new species of the genus Tipulodina Enderlein, 1912, Tipulodinabifurcata Xue & Men, sp. nov. (Guangxi, South China) is described and illustrated. A key to the known species in China is provided. The morphological description of the female internal reproductive system of the new species is provided, which represents the first description for this genus.

New information on the skipper fauna of Guangxi, China (Lepidoptera, Hesperiidae).

The skipper fauna of Guangxi is updated based upon field surveys and examinations of specimens. Two genera and 16 species/subspecies are recognized as new records to Guangxi, of which one genus and four species are recorded from China for the first time. Distribution of seven species/subspecies in Guangxi are confirmed as well. The females of four species are described for the first time. The male genitalia of three species are illustrated and re-described. Taxonomic notes on some of these species are provided.
