Abstract

The ant genus Temnothorax Mayr, 1861 (Myrmicinae, Crematogastrini) is diverse with 498 species described. Species are distributed predominately within the northern hemisphere with species richness decreasing closer to the tropics; contrary to other ant genera overall. In Southeast Asia, richness is relatively low and knowledge on the genus remains fragmentary, likely due to poor sampling efforts compared to temperate regions. Here, using specimens from recent sampling efforts, Temnothorax is reported for the first time from the Hong Kong Special Administrative Region. Two new species, T. barrettoi Hamer & Guénard sp. nov. and T. haveni Lee, Hamer & Guénard sp. nov., are described based on qualitive morphological characters, with additional morphometric data also gathered. An updated key, as well as a distributional checklist of Temnothorax species from mainland China is provided. We suggest that the two new species are likely arboreal based on our collections, however, further arboreal sampling is necessary to confirm this hypothesis. We hope this study may spurn effort to generate further information on sub-tropical Chinese Temnothorax species.
石竹属的首次记录,1861年(蚁科:石竹科)在香港,并有两个新种的描述
蚁属Temnothoras Mayr,1861(Myrmicinae,Crematogastrini)多种多样,共有498种。物种主要分布在北半球,物种丰富度在热带附近下降;与其他蚂蚁属相反。在东南亚,物种丰富度相对较低,对该属的了解仍然零散,这可能是由于与温带地区相比,采样工作不力。在这里,使用最近采样工作的标本,首次报道了香港特别行政区的特姆诺胸。根据定性形态学特征描述了两个新种,T.barretoi Hamer&Guénard sp.nov.和T.haveni Lee,Hamer&Gueénards.nov.,并收集了额外的形态计量学数据。提供了一份最新的中国大陆毒胸属物种分布表和检索表。根据我们的收集,我们认为这两个新物种可能是树栖的,然而,需要进一步的树栖采样来证实这一假设。我们希望这项研究可以推动进一步了解亚热带中国毒胸属物种的努力。

期刊介绍: EJT is a fully refereed, international, fully electronic Open Access journal in descriptive taxonomy, covering subjects in zoology, entomology, botany (in its broadest sense), and palaeontology. EJT-papers must be original and adhere to high scientific (content) and technical (language, artwork, etc.) standards. Manuscripts that are clearly substandard in either of these categories will not be sent out for review. EJT is supported by a consortium of European Natural History Institutes, but its scope is global. Both authorship and geographical region of study need not be European. Authors are, however, strongly encouraged to involve European Natural History collections by consulting material or by depositing specimens (e.g. types and figured material) related to their published paper in the collection of a European Natural History Institute.
