Abstract

Available information on Gynacantha Rambur, 1842 species from the South Pacific is reviewed. Specimens were found to be sufficiently similar to G. rosenbergi Kaup in Brauer, 1867 to be placed in the same species group (G. rosenbergi group-established here) but also distinct enough to form a subgroup of its own (G. rosenbergi Pacific group). All species of the G. rosenbergi group are diagnosed, with three species, Gynacantha vitiana sp. n. (male and female) from Viti Levu, Fiji, G. koroana sp. n. (male) from Koro, Fiji and G. vanuatua sp. n. (male) from Malekula, Vanuatu being described as new to science. A key is presented for identification of the males.

摘要

对1842年发现的来自南太平洋的Gynacantha Rambur属物种的现有信息进行了综述。发现这些标本与1867年布劳尔所描述的G. rosenbergi Kaup足够相似，可归入同一物种组（在此建立的G. rosenbergi组），但又有足够的差异，足以形成其自身的一个亚组（G. rosenbergi太平洋亚组）。对G. rosenbergi组的所有物种进行了诊断，其中有三个物种，即来自斐济维提岛的新物种Gynacantha vitiana sp. n.（雄性和雌性）、来自斐济科罗岛的新物种G. koroana sp. n.（雄性）以及来自瓦努阿图马列库拉岛的新物种G. vanuatua sp. n.（雄性）被描述为科学界新发现的物种。给出了一个用于鉴定雄性的检索表。
