The Roger, 1861 (Formicidae, Ponerinae) of Hong Kong SAR with additional records from Guangdong, China.

is the most diverse genus of the ant subfamily Ponerinae and is widely distributed across the world's tropical and subtropical regions. More than 40 species are known from the Oriental realm displaying a wide range of ecologies, although their life history traits remain poorly understood, and new species are frequently discovered. Here, a faunal review of the genus from Hong Kong SAR, southern China is provided.

Strumigenys emmae (Emery, 1890) (Myrmicinae) new to Britain, with an updated key to the known Strumigenys of the West Palaearctic.

The ant genus Strumigenys is a hyper diverse pantropical group of specialised predatory leaf litter dwelling ants. Species richness peaks within tropics, with few species extending into the West Palaearctic realm. A significant proportion of Strumigenys species known from the West Palaearctic are non-native, spread via human commerce, and predominately establishing populations within artificially heated greenhouses.

A checklist of Nylanderia (Hymenoptera: Formicidae: Formicinae) from Hong Kong and Macao SARs, with an illustrated identification key for species in Southeast China and Taiwan.

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.
