Species of the ant genus Nylanderia constitute some of the most common ground dwelling Formicinae in tropical and subtropical areas. The genus includes numerous species introduced into new regions, especially within urban or disturbed environments. Here, we review the Nylanderia species found within Hong Kong and Macao, which are both highly urbanized regions and of critical importance to Southern China's policy-makers and non-governmental actors concerned with the regional spread of non-native species. A total of 11 species and 2 morphospecies are recorded in Hong Kong and 6 species and 2 morphospecies are recorded in Macao. We also provide a list of new records for the genus in Hong Kong and Macao, along with taxonomic accounts for all the species recorded. Additionally, the present work provides an illustrated identification key for the species of Nylanderia occurring in Southeast Mainland China and Taiwan. We briefly discuss the possible biogeographical implications of our findings, providing additional support to the exotic status of N. bourbonica in continental Southeast Asia. Lastly, we give our perspective on the ramifications of local inaccessibility to type specimens to current taxonomic practices.

Ponera is a widespread genus of litter and soil ants. The highest diversity of the genus is found in Asia, with Taiwan and Japan being two of the most species-rich regions. Here, we systematically review the taxonomy of the 16 Taiwanese and Japanese Ponera species, two of which are new species from Taiwan: Ponera terayamai sp. n. and P. wui sp. n. A new key for Ponera species of East Asia is presented.

The genus Myopias Roger, 1861 is distributed in the Australian, Oceanian, Oriental and southern Sino-Japanese realms. Currently 40 valid species and three subspecies have been described, but none have ever been recorded for Thailand. Here we review the species of Thailand, recognizing seven in total. Four are new records of previously described species: Myopias bidens (Emery, 1900), M. crawleyi (Donisthorpe, 1941), M. maligna punctigera (Emery, 1900), and M. mandibularis (Crawley, 1924). Three new species are described: Myopias minima sp. nov. from southern Thailand, M. sakaeratensis sp. nov. from eastern Thailand and M. sonthichaiae sp. nov. from northern and western Thailand. The queen caste of M. mandibularis is described here for the first time and additional descriptions of other species are provided. All these species were found to nest in rotten wood on the forest floor.

Recently a new species of bombyliid fly, Marleyimyia xylocopae, was described by Marshall & Evenhuis (2015) based on two photographs taken during fieldwork in the Republic of South Africa. This species has no preserved holotype. The paper generated some buzz, especially among dipterists, because in most cases photographs taken in the field provide insufficient information for properly diagnosing and documenting species of Diptera.

A recent species checklist of the ants of Peru recorded 592 nominal species and 79 genera on the basis of a literature review. Here we complement the previously published checklist with the addition of 83 nominal species and six genera, including three genera recorded only from morphospecies. This increases the list of ants reported from Peru to at least 679 species and subspecies and 85 genera. We also modify the list of species known as endemic from Peru, discuss the historical importance of the Peruvian ant fauna in myrmecology, and highlight potential research for future studies.

The genus Bannapone was described in 2000 on the basis of a single dealate queen specimen. Since its original collection in Yunnan, China, no other specimen has been reported, making it one of the rarest ant genera in the world. Here we report the collection of two workers of Bannapone also from Yunnan province. The description of the worker caste is presented. Furthermore, we found significant differences with the described B. mulanae Xu, 2000 which leads us to describe the workers as a new species, B. scrobiceps n. sp.. Finally, we briefly discuss the importance of leaf-litter collection methods to collect taxa considered as "rare".
