Xenohalacarus longirostris n. sp., (Acari: Halacaridae: Lohmannellinae), a new genus and species of marine mite from Chilcott Islet in the Coral Sea

A new genus and species of marine mite, Xenohalacarus longirostris n. sp. was described from Chilcott Islet in the Coral Sea. One female, 1 male and 3 deutonymphs were extracted from coarse coral sand collected from the reef slope at Chilcott Islet on 14 September 1998. The reef slope was covered with algae, hydroids and rubble. This research was conducted as part of a survey of marine mites from northern Australia. The holotype, a female (QMS105614) and paratypes, a male (QMS105615) and 3 deutonymphs (QMS 105616-105618) were lodged with the Museum of Tropical Queensland, Townsville.

本研究记述了采自珊瑚海（Coral Sea）奇科特岛（Chilcott Islet）的海螨（marine mite）新属新种：Xenohalacarus longirostris n. sp.。1998年9月14日，研究人员从该岛礁坡采集的粗珊瑚沙样本中，分离得到1头雌成螨、1头雄成螨及3只第二若螨（deutonymph）；该礁坡生境覆盖有藻类、水螅类生物及珊瑚碎块。本研究为澳大利亚北部海域海螨类群调查项目的组成部分。正模标本（holotype）为1头雌成螨（标本编号QMS105614），副模标本（paratypes）包括1头雄成螨（QMS105615）及3只第二若螨（QMS 105616-105618），上述标本均保存于汤斯维尔市热带昆士兰博物馆（Museum of Tropical Queensland）。
