New taxa in Hesperiidae (Lepidoptera: Papilionoidea) are traditionally proposed after inspection of male genitalia, which largely form the basis for Hesperiidae taxonomy. However, with genomic DNA sequencing, even a single female specimen can be placed in a phylogenetic context of existing classification and taxonomically assigned with confidence. Genomic sequencing of an unusually patterned Hesperiidae female from San Martin, Peru, characterized by pearly spots outlining an inverted heart pattern on the rust-colored ventral hindwing, reveals that it represents an undescribed genus and species named here as Gemmia buechei Brockmann and Grishin, new genus and new species.

Tapinesthis inermis Simon, 1882, the only species in the genus, is widely distributed in western Europe. This redescription provides the first information on the ultrastructure of the species using SEM. The morphology of the spinnerets, tarsal claws and tarsal organs, and the internal structure of the female genitalia and the male palp are described and illustrated in detail. The combination of these structures is very similar to those encountered in some dysderoid spiders and supports the basal placement of Tapinesthis among Oonopinae. The phylogenetic relationships of the species are discussed. The only female among the three syntypes is designated as the lectotype.
The genus Oryctopterus Karny, 1937 (Orthoptera, Stenopelmatidae, Oryctopinae) is reported from India for the first time and two new species, Ot. varuna sp. nov. and Ot. yeshwanthi sp. nov. are described. Male and female external genitalia of Ot. varuna sp. nov. and female genitalia of Ot. yeshwanthi sp. nov. are figured and described. Notes on seasonality, food habits and behavior of Ot. varuna sp. nov. are provided.
Neofidia Strother nom. nov., is proposed as the replacement name for Fidia Baly, 1863, a junior homonym of Fidia Motschulsky, 1861 (not 1860, Griffin 1936). A list of the included species of Neofidia Strother nom. nov. and Fidia Motschulsky, 1861 is provided for clarity. Fidia medvedevi nom. nov. is the new replacement name proposed for Lypesthes vietnamicus Medvedev, 2015. Fidia kanaraensis (Jacoby, 1895) is redescribed and habitus, male and female genitalia are figured. Cashew (Anacardium occidentale L.) is reported as a new host of F. kanaraensis and partial information on the life history is provided. Eggs are laid singly on the surface of soil, and are covered with excreta and soil. Larvae tunnel into the tender roots. Adults are nocturnal and feed on tender leaves.
The phylogenetic relationships of the species of Padunielia are analyzed based on characters of larvae, pupae, and adults (mainly male genitalia). The genus is monophyletic and most closely related to Psychomyia, and Metalype in the subfamily Psychomyiinae. Nine species groups are suggested. Eight species, including six new to science, are reported from the People's Republic of China for the first time.
